Baumgardner, being of full age and first duly sworn do hereby state: 1. I am the Research Coordinator for the Claims Resolution Management Corporation ("CRMC"), a wholly owned subsidiary of the Manville Personal Injury Settlement Trust ("Trust"). The CRMC was created in December 1998 and is staffed by former Trust employees. On January 1, 1999, CRMC began providing claims resolution facility services to the Trust. 2. In this position, I manage the Asbestos Claims Research Facility ("Facility"), a document and records repository, located at 4755 East 46th Avenue, Denver, Colorado. The Facility contains the business records including but not limited to correspondence, memoranda, reports, records and data compilations ("records") ofManville Corporation or related entities ("Manville"), generally, as well as Manville records relevant to litigation of asbestos liability. The Trust has managed and operated the Facility from November 28, 1988, the date on which the Manville bankruptcy plan was consummated. 3. My experience and familiarity with the documents at the Facility began in 1983 while working for Manville. In my work as a paralegal for Manville, I assisted in locating, indexing and packing many ofthe records which became the foundation documents for the Facility. I continued to work for Manville until September 1987. From March 1988 to September 1988, I was hired to supervise and assist in the indexing of the first 20,000 boxes which were turned over to the Trust in November 1988. From September 1988 to January 1989, I assisted in the privilege review of documents to be given to the Trust. From November 1988 to April 1994,1 worked for Freeborn & Peters and was put in charge of the Facility, managing all productions and "new" acquisitions. In September 1995,1 was hired by the Trust to manage the Facility. In December 1998,1 was hired by the CRMC to manage the Facility for the Trust. Accordingly, I am personally familiar with many of the records stored at the Facility, as well as how the records have been gathered. 4. To the best of my present knowledge, information and belief, I certify that these records were m ade a t o r n ear t he t ime b y, o r from i nformation t ransmitted b y, a p erson w ith knowledge, were kept in the course of the regularly conducted business activity of Manville, and it was the regular practice and the business activity of Manville to make the records. Margaret J.

C. Kelleher Experimental runs of tissue including 2% and U% 7D04 fiber were conducted on Doeskin Products Company's No. 4 machine on 1/31/56. The No. 4 machine stock system includes a Hydropulper followed by a 36-in. Bauer Refiner and a Jordan. There is a stock chest between the Hydropulper and Bauer. The Bauer is a 36-in. double disc unit driven by two 50 H.P. motors. Throughput is between 900 and 1000 lbs per hour. The refiner is usually run with .005-in. clearance between plates and the Jordan is set to do a little brushing and no cutting on the stock. White water goes to a settling system including a flotation unit built by Infilco. This part of the system was not in operation probably due to river conditions. The water supply was highly colored and included a high content of brown colloid material. This made it advisable to spill excess white water rather than recycle it through the saveall system. Machine speeds at this time with cold water are in the range of 900 fpm. However, on regular grades the machine had been operating at 760 to 780 previous to the start of the trial runs. First batches of stock including asbestos were made up in an old Umpherson beater. Two per cent 7DQ4 was added. Successive beaters included A% but due to paper machine conditions usage was cut back to 2%, . The Hydropulper was then employed for fiberizing instead of the beater. The 2% asbestos stock ran about the same as regular on the machine. The fourdrinier has micarta baffles supporting the wire instead of table rolls. There are three such supports between the stock inlet and the suction box. The sheet is substantially dewatered after passing the suction box. The couches are plain and considerable water is forced through the wire at this point. When U% asbestos stock was run, the sheet was not dry on leaving the suction box and a torrent of water was forced out at the couch. This resulted in a wetter sheet going to the dryers and a reduction in machine speed to 710-720 fpm.- The wire on the machine was 85 mesh bronze. Some improvement in operation resulted when the Jordan was backed off. However, head paper maker decided it would be unwise to continue at U% because the sheet was near minimum on strength and there was some question as to whether or not it would carry through the converting units. Current specification for strength is 320 grams. The 2% sheet tested 345. The regular sheet runs between 360 and 400 grams. The freeness of the regular stock is 600 to 630 ml. With 2% asbestos this had been reduced to 550. No reading was obtained on the U% but performance on the wire indicated a drop in drainage rate below that obtained at 2%, Adjustments of the refiners, both Bauer and Jordan, can compensate to some degree for the slowing of the asbestos. However, when this is done the sheet strength drops off. MT06071 Page 2 Softness comparisons were made by mill personnel and all were in agreement that the asbestos sheets were softer than regular. There are no instruments in the mill for softness tests. Several jumbo rolls were converted into towelling with results said to be equal to regular. This converting operation involves embossing two sheets together employing a steel and a composition roll. Some sticking occurred to the steel roll. This was said to be experienced when the strength of the tissue is low. (We believe formation is also a factor in this and the 4/6 tissue was poorly formed). The tissues included a small amount of specks. The mill planned originally to make speck counts on the production. This idea was abandoned due to the small number. The brightness of the asbestos content tissues was not as high as regular but due to the presence of brown coloring matter in the water, no direct comparisons could be made. The crepe was held at 15/6 and the inclusion of asbestos did not alter its character. A flocculant was brought along with the fiber with the object of improving drainage through addition at the head box. There were no facilities available to dissolve the compound, Separan 2610, and a part solution - part suspension, was flowed into the stock as it entered the machine head box. There was no difference in drainage performance evidenced with the flocculant. Usage was estimated at about .5/6 of asbestos fiber weight. It is possible that the river water colloids exhausted the flocculant. There was some slight change in color of the sheet when the flocculant was added. The mill planned to continue the run until all the asbestos was used up. They believe that they can use 2/6 regularly and are Interested primarily in displacing $140 per ton bleached pulp with $85 asbestos. At 2/6 they estimated their asbestos requirement at 250 tons per annum. Results of the run will be reviewed by Messrs. Smith and Phillips with Mike Donovan on February 7 or 8. Research Center evaluations of the several samples developed the following data: Asbestos Content, % Weight grams/sq ft Crepe % Water Absorption, % Castor Oil Absorption, % Kerosene Oil Absorption, % 0 1.60 10 530 1880 422 2 1.70 15 630 2140 425 -L1.55 10 520 2600 316 Comparative samples are attached.

JOHNS-MANVILLE RESEARCH AND ENGINEERING CENTER 4// - * Memorandum Mhll-333 Date December 23, 19&3 VISIT TO SCOTT PAPER COMPANY, PHILADELPHIA, PENNSYLVANIA - December 13, 193 Those present: Mr. K. M. Fox - New Materials Coordinator Mr. C. W. Hurley - Development Engineer Mr. J. E. Connor - Johns-Manville Dr. J. W. Axelson- Johns-Manville DEC JO rj63 Some time ago, samples of AX-2950 and AX-295 "were submitted to the Scott Paper Company for evaluation in tissue-type papers. Experimental runs were made on a 10-inch paper machine incorporating 10 and 20$ of each of these fibers in a Soundviev pulp furnish. No heater or other fiber refining procedure was used. A report on the results of these runs was given to us as well as small rolls of paper remaining from the investigation. As expected, the tissue made with asbestos fiber in the furnish had a somewhat softer feel to it than the control samples without asbestos. However, there was a very marked decrease in the tensile strength of paper and also an appreciable drop in the absorptivity. In this case, absorptivity refers to the time in seeonds required for 0.01 ml of water to disperse in the sheet. This test, therefore, measures the speed rather than the capacity for absorption. Based on the results of this investigation, the Scott people concluded that these two grades of asbestos fiber could not be used in their tissue. However, they in dicated that they would be willing to evaluate additional material if we had some indication that it would overcome the difficulties encountered'in this case. JWA:jms cc: C. F.

LIMITeB' ' ~ `35* J,.v` Hart; ASBESTOS FIBRE DIVISION BULLETIN 4/13/59 , f] ASDHSXOS FIBRE Foil TISSUE PAPERS The Johns^aar.ville Is search Centre has developed a specially processed asbestos fibre for use in tissue paper. This 'special fibre ;vill be known as "Asbestos Fibre For Paper Ho. 301" . It will be packaged in cardboard cartons,, and will sell at the price of 3.150 per ton. It is available in sample quantities only until production equipment i3 in operation in June of this year. Much of the development work has been done in connection with a paper manufacturing company, A summary of three tost runs is included as Appendix I0 Specific figures relating to the last trial run are recorded in Appendix II0 Comments or A.G, quinn of Research Centre are extracted from a letter and included in Appendix III. .ample stocks of this fibre are being layed in at Asbestosj, and snail samples will be sent forward at once. Production machinery is scheduled to be installed in the Mills and should Joe ready for production of this special fibre within the next six weeks to two months. Potential paper making customers who are interested in asbestos and have received samples and small shipments of standard fibres are listed in Appendix TV, It should be stressed to such people that this special paper fibre is an entirely different product from that 'which they have seen before. It is a highly cleaned and highly opened fibre.* giving increased strength and softness to a tissue paper. It also has suitable brightness and dyeing characteristics for use in white or colored papers A few of the questions which have been raised as to the suitability of asbestos fibre in tissue papers and our comments are listed in Appendix U', Many of these questions car, be answered better by paper manufacturers than by fibre producers, h'e hove every intention of taking full advantage of the specialized assistance that is available to us at our Research Centre in the solution of a genuine problem. However, we also expect a prospective user to recognize sufficient advantages in the asbestos fibre to justify him going halfway in overcoming potential difficulties} hypothetical, or otherwise* All of this special fibre which is available has been mods on the pilot machine at Research Centre, and while sample stocks are on hand at Asbestos, it is limited until the production machine is in operation.

First Bun (Report 8/29/57) (a) of tissue fibre added (b) Paper machine remained at .normal speed of 850 ft. per minute (c) Water stock was affected, but easily rectified. (d) Increased softness was very apparent. Results of tests made at Research on the above run proved inconclusive. Second Run (Reported 5/13/58) (a) Best Restigouche pulp was used. (b) 5% tissue fibre added. (c) Paper machine speed was 890 ft. per min0 (d) No machine difficulties were experienced. (e) Results showed a better formulation of sheet and softer tissue. Third Run (Reported 7/14/58) , (a) Cheaper pulp and worn felt were used. (b) tissue fibre added. (c) Results showed that asbestoss- (1) Closes the stock and improves the formation of the sheet (2) Permits usage of cheaper pulp satisfactorily (3) Cuts down on soda pulp. CONCLUSIONS 1. The addition of specially processed asbestos fibre to facial tissue permits the usage of cheaper pulp. 2. Paper machine can be run at norma! speed without difficulty. 3. Results show a better formation of the sheet and a softer tissue. 4. Further tests have shown a good dispersion of asbestos throughout the sheet.

G. QUINN "Asbestos grades suitable for tissue have a freeness in the 200 to 350 range* depending upon the degree of refining in the mill. Disc mill treat ment appears to develop more fibre fineness without as much slowing as experienced with beaters and jordans. The asbestos is comparatively inert and tends to prevent coagulation, or clotting, of the cellulose fibres, and in this way assists formation* The lower drainage rate also makes for better fibre distribution on the wire. "We have used the Clark softness tester to compare softness of tissues with and without asbestos. On facial with an actual asbestos content of 1.56 per cent, the tissue was 17.5 per cent softer In machine direction and 37 per cent softer in cross direction. Clark values were 168 and 1105 re spectively. Retention was 76 per cent in a mill having a fully open system. "The asbestos tissue fibre classifies approximately 10 per cent on 14 mesh and 30 oer cent through 200. It has a G0E0 brightness of slightly over 70 per cent. . "Two sidedness may be encountered in forming handsheets due to the faster settling rate of the asbestos. This may be offset with a small percentage treatment of the asbestos with a dispersant such as Blancol, Marasperse or other concentrated ligno sulphonate# It has been found that 5 per cent and less asbestos will effectively soften facial grades and 2 to 3 per cent cf the asbestos weight in dispersant would represent very little usage on the full furnish basis. The asbestos stock should be treated with the dis persant before it is mixed with the rest of the furnish."

Our Medical Director has advised that we have no reason to ex pect harmful affects in any such case. 2, Question: What will be the affect of such an indestructible material as asbestos in'septic tank systems. Answer * While we cannot see that the small percentage of asbestos included in tissue paper vail hasten the day that a septic tank will have to be cleared of sludge, we recognize that paper makers may regard it as a problem and are asking expert advice from our General Plant Engineering Division, 30 Question: What is the affect of differential dye acceptance between the asbestos and cellulose fibres in a paper stock. Answer: A,,Pe Gouveia of Research has replied that the opened fibres will accept certain colouring and considering the small amount of crude fibre present, there should be no discernable difference in the finished product. Practically all questions of such detailed and specific nature as the foregoing are best answered by specialists within their own field, which we would naturally expect to find within the paper industry. They should not be allowed to confuse the issue by being thrown in as "red herrings". However, if there is a sincere requirement for consideration of a potential problem by our people let us know and we will get an answer if possible. MT06087 A.F.D. ASBESTOS June 28th 1956/ R. G.

William A third trial run was conducted on May 13, 1958 at Golden Fleece Mills to demon strate the softening action of short, air cleaned asbestos fiber on facial tissue. Previous runs were unsatisfactory due to low retention with 7D04 (Research Report 441-394) and to low percentage usage (Research Report 441-394, Si) of air cleaned fiber. The fiber used in the third trial was prepared by the Asbestos Fiber Section. It was a Russum Cleaner material prepared as described in Research Report 411-237. The percentage asbestos supplied in the furnish was 5.2. Finished tissue contained 4.44 percent asbestos, so that the retention was 85.2 percent, which is high. The immediate action of the asbestos was to greatly improve sheet formation. Mill operators classified the asbestos containing tissue as softer than regular. The Clark Softness tester results showed the regular to be softer in machine direction and the asbestos sheet slightly softer in transverse direction. The asbestos tissue appeared slightly weaker to the operators. Analyses of dust removed from spreader bars between the Yankee Dryer and reel showed a higher asbestos content (18.2 percent) than the sheet. As the wire side of the sheet only contacts these bars it is reasoned that because of the faster settling rate of the asbestos fiber on the fourdrinier wire, the asbestos content of the underside of the sheet is considerably higher than that of the topside. The weight of the asbestos tissue averaged 18.6 grama/sq cm as compared with 17.9 grams/sq cm for the regular. The percent crepe of the asbestos sheet was 29.6 as compared with 31.4 percent in the regular. Moisture contents of testing humidities were approximately four percent. Paper machine speed was 890 ft/min. The value of Russum asbestos in facial tissue is primarily a question of economics. Contents: Summary and Discussion. Approved by Parkinson cc C. F.

D SUMMARI MAY 1 3 1958 A second trial run has been arranged with the Golden Fleece Company to produce tissue paper containing cleaned asbestos shorts. As in the first run, the fiber was prepared in the Russian cleaner from the rejects of previous cleaning of 6JX20. However, the present feed contained less long fiber than formerly, resulting in a cleaned product which was very low in +14 mesh material. The fiber tended to nodulate and was judged unsatisfactory to use as such. An acceptable product was obtained by blending with longer fiber, which was produced by cleaning, opening, and screening 6D20. The procedure described in this report is undoubtedly not the most desirable/ but if the fiber produced is satisfactory, then its properties can perhaps be duplicated by other, more efficient ways in the future. The final product for shipment to Golden Fleece amounted to 250 lb, resembled a clean 4Z, and contained 5.1 per cent +14 mesh fiber and 31.2 per cent fines.

On February 7th the writer visited the Pulp and Paper Research Institute of Canada and discussed with Dr, R, de Montigny the results se far obtained with the use of asbestos In tissues. Dr, R, de Montigny was formerly Technical Director for the 1B, Eddy Paper Mills in Ottawa, The primary reason for this call was to determine the value of these results and the possible interest of the Paper Industry adopting asbestos fibre as a raw material. As Dr, de Montigny is familiar with all the work done prior to the development of Russum cleaned fibre# we reviewed the retults of the first test using Susaum cleaned fibre at the Golden Fleece Company, Me believed the good operating results plus the increase ia softness as measured by the Clark tester warrants a further trial. However# he cautioned that although softne s is important other characteristics such as absorbency and tensile strength are criticc I I asked him what characteristics tissue manufacturers considered most important or desirable for good consumer acceptance. He listed them with one or two qualifications in the following order of importance# le,t Softness Tensile Strength Absorbency MT06095 Brightness This order would cover toilet and facial type tissues, for domsttlc and industrial typa towelling - strength end absorbency might assume equal importance with softness.

This specification developed from previous trials made at Scott, Doeskin and Golden Fleece mills. The fiber batch compared with the specification as follows: Plus 14 mesh Cumulative + 100 mesh Minus 200 mesh Actual 9.4* 52* 28* Specified 15 to 20* 55*min. 30*max. The fiber was added to a yellow colored tissue furnish at Golden Fleece mill on August 29, 1957. Fifty pounds were furnished to a cheatvith 1250 lb rated capacity with the object of getting four percent asbestos into the mix. However, analyses indicated 2.05 percent asbestos in the furnish. The sheet on the same basis was found to contain 1.56 percent asbestos, so that the retention was 76 percent. Upon addition of fiber it was immediately necessary to decrease water usage in the stock going to the fourdrlnler so as to maintain sheet weight. The asbestos closed up the sheet and Improved formation. Some white asbestos particles were noticeable in the tissue due to inability of the asbestos to adsorb the coloring. These were not judged objectionable particularly since they were as soft as the rest of the sheet. All operators rated the asbestos containing tissue as softer than regular. The differences were not obvious in softness but an improvement in formation was readily observed. Laboratory tests showed the asbestos content tissue to be 17.5 percent softer by Clark Softness Tester measurement in machine direction and 37 percent softer in cross direction. Golden Fleece plan to make further trials late in September or early October. Results Indicate the fiber is a desirable fraction for this application. Contents: Summary and Operating Details cc C. F.

MARX 4 >95/ "SO** Sunraarv of Development* to Data Asbestos fibre has been experimented with in various tissue products, primarily to increase the surface softness and absorbency of the sheet. Our contacts have been Scott Paper Co. and Doeskin Products in the U.S* and the E.B. Eddy Co. in Canada. Other contacts were made, however, the bulk of the experimental wort was carried on in co-operation with these companies. Initial experimental wort by Scott Paper Co. indicated that the addition of small percentages of short asbestos fibre to the tissue stock in creased the surface softness in the sheet. One other advantage was the price saving on asbestos fibre at approximately $80.00 per ton over cellulose stock at $140.00 to $160.00 per ton. During these initial tests several disadvantages were evident, but it was felt that the possible increase in softness, plus the price saving justified further exploration of this potential use. After making laboratory tests. Doeskin Products made an experimental production run on tissue towelling, using 7% and then 4 7D04 in the stock. The addition of 7% asbestos had the following effects, i.e.t Reduced machine speed 800 - 780 ft./ndn., brightness slightly off but acceptable, slight improvement of surface feel. The addition of asbestos was then increased to 4Jf with the following results, i.e.t Machine speed reduced to 710 ft.Ain.', brightness slightly below standard, reduced tensile strength, improved surface softness, no objectionable specks. Based on these results, Doeskin were impressed with the increase in softness, oil absorption, plus the saving in cost of pulp, and ordered one ton of 7D04 for further trials on ai1 machines using 4#. That was back in January *56, for various reasons these trials have been con tinually postponed by this company, and the chances of them being made now seem remote. MT06101 iaa 2 Results from the work done at the E.B. Eddy Co., Ottawa, were more conclusive, but less encouraging. Asbestos shorts 7D04 were tried here in varying percentages, from 1# up to 4$, in toilet tissues and groundwood towelling, 6 tons of 7D04 was purchased for these experimental production runs* The asbestos had little or no effect on the softness of the towelling, there was a marked deterioration of agsd absorbency, also the re* tentlon of asbestos in the finished sheet was low, approximately 3OJf* In tissues, softness improvement was marginal, and could have been within experimental error. There was no beneficial effect on absorb* ency, again the retention was low at approximately 259C. Generally speaking, results were comparative in all cases, and could be summarized as follows! Little improvement in softness. Low retention in finished sheet. Reduced tensile strength, reduced machine speed. While these were the main objections experienced, other disadvantages were encountered which varied from plant to plant. From our experience with these companies and others, it has been con* eluded that there is a large potential market for a fibre of satis* factory length and quality, somewhere in the region of 30,000 tons, in the U.S. and Canada. Such a fibre would be of 7D length, high in fibre content, well opened, low in -200 mesh fines. Research have suggested the following as an ideal target for a satis factory fibre, based on McNett values. +14M Cum +100M -2Q0M 20.0 Max. 15.0 Min. 55 Min. 30 Max. It appears that there are two means by which we could produce such a fibre, i.e.< 1. Cleaning of 7D04 by air elutriation. 2. Extracting an ideal fibre from tailings by screening. A Sales product request has been issued and approved. Research and Development are now constructing as rapidly as possible a new method of dust and rock removal. MT06102 3 Elana for futurt PmlflaMQt Upon completion of this experimental pilot plant at Research* a sufficient quantity of cleaned fibre will be sold to a customer for use in tissue paper to prove the value of the fibre and cheek the production costs* A second method to remove the ->200 mesh dust fraction by wet washing will also be considered. J.O. Eby will meet with members of our Research staff to discuss the possibilities of this method* Scott Paper Co. are ready and willing to discuss the requirements of a satisfactory fibre for tissues* and any other pertinent pro blems connected with the production and usage of such a fibre.

Kelleher - Aabeatoa Scott Paper Company Cheater* Pennsylvania At present subject has H)0# bag of 6 D AX 2494 M. They secured it with the purpose of evaluating In paper towels. As of 1-12-56 very little had been done along thia line. However* they did show me a paper towel containing 12% 6D. It was a grand piece of merchandise. It was soft and absorbent and had a very pleasing feel to the skin. However* at present* machine speeds it is not a desirable product - production-wise. They did tell me that they are revising their thinking and beginning to evaluate products producable at speed of 200 to 300 ft. /min. In this field asbestos has a place. They are also con sidering producing tissue without crepeing. Here also asbestos could find a place as one of objections raised against asbestos was its effect on crepeing. Hence - no crepeing - no trouble. All personnel in technical development and research are well acquainted with the good and bad properties of asbestos and they believe that within the next year or two asbestos will become one of their standard raw materials. While it may not find a place in all presently produced products* they feel it will definitely go into some new products now under development. We have spent five years of time and effort (plus many samples) on this ac count. My personal belief is that it has been time and money well spent. We have established that asbestos can be used in this industry. We have sold the largest producer of tissue on the good properties of asbestos. Ws have one of the largest research and development departments (devoted to paper products) looking for possible uses of asbestos in that industry. Samples of paper pro ducts have been produced on a lab scale containing asbestos and have shown improved properties which have a definite retail customer appeal and (feel* softness* absorbancy). These are good solid reasons why I believe that the demand for asbestos in paper products will approach that which now exists for asbestos in building products within the next ten years. , cc: W. N.

R. Williams The addition of three per cent of refined, centricleaned 6DAX 2469M to wiping tissue increased the softness. The accompanying loss in sheet strength, low asbestos retention (56$), decreased stock drainage rate, and the presence of asbestos clots in the sheet indicate a need for changes in the fiber processing procedure. Evaluations of other fibers might also aid in the development of an asbestos fiber for tissue. The possibilities of developing an acceptable fiber for this application are not promising due to the comparatively slow drainage properties of short flbered asbestos.

Parkinson File (3) 7//. (1. Reported by: M. C. Hutchins MT06106 Chester, Pennsylvania E R WlLLlAMSf Two bags of 6DAX2469 fiber were taken to Scott on Friday, June 17 and delivered to Messrs. Sparrow and Coppick of their Research Laboratory. The fiber was checked by the Asbestos Fiber Section and the McNett Classifications were as follows: + 14 + 28 +100 +200 -200 - 14.8 - 9.6 - 11.1 - 7.3 - 57.4 Air Analysis Fiber - 53.4$ Dust - 29.5$ Rock - 17.1$ This fiber is higher in dust content with the specification of 53$ maximum suggested, and is somewhat lower in +14 mesh than the 17$ hoped for. The Scott people looked at the fiber under the microscope but made no comment. The trial run made in the mill a month or two back was discussed briefly. It was established that or 7 mm* ai. LJ UJ (1) The paper did not crepe evenly. o (2) Moisture content of the sheet was excessive necessitating extra x: drying load. (3) Retention of asbestos was low and was calculated to be in the 20 to 30$ range. Tff '>. w (4) Asbestos performed its function of softening the tissue even at 2%f> to 3$ usage. (5) Asbestos slowed the save-alls down due to high fines loss through the fourdrinier wire. . There were no facts available as to the machine speed or f reeness with and without asbestos. Neither were the Scott men acquainted with the treatment ahead of the jiiper machine. They stated that a Jordan and a Dirtec were used but had no " ticulars. It is apparent that the trial was not followed too closely and was lied in a half-hearted manner. Johns-Manville personnel should have an Dortunity to cooperate in such runs if we are to make progress. We don't know for sure whether the fiber was lost in important amounts at the Dirtec, whether it was ground too much or anything definite to use as a base for further suggestions. In reference to points 1 and 2 above, it is likely that the excessive moisture reported may be responsible for the uneven, inadequate creping result. The Scott men reported their laboratory investigations shewed that 3$ asbestos (Bauer ground AX2494M) dropped the stock freeness about 100 points Canadian Standard freeness. They operate at 450 c.c. We plan to check this action on their stock here. The interest in asbestos fiber has dropped due to the failure of the last run. However, if we can give them a material that will not slow up either their machine or save-all operations, it would revive the project. MT06107 -2- A short discussion was held on the possible use of coagulants to offset the slowing action of asbestos. They have investigated such products as Separan and found they do not flocculate the cellulose fibers. It is likely, therefore, that such materials being outstandingly effective on asbestos would fit into the picture. We also will investigate this in our laboratory. Coppick showed us the Bauer Cleaner and Refiner available for trials in their Research Laboratory. The cleaner is a 606 model and the refiner is a single disc laboratory sample grinder. With this setup, the chances of preparing a good sample of asbestos are not good. The plates have about 4" diameter working surface and in order to open up pencils the discs would have to be set up close resulting in the generation of fines. Coppick was aware of this and asked that we prepare four or five pounds on our equipment and supply it to him wet. This we agreed to do. If Scott's story that 3% asbestos produces the softness increment desired is correct, I think we have a pretty good chance of working this application out to tueir satisfaction. RGQ:ho ccs H.

I J. C. Kelleher, A.F.D., Montreal Asbestos Fiber Scott Paper Company Chester, Pa. Mr. Donovan and the writer discussed the use of asbestos fiber in tissues yesterday with Messrs. Sparrow, Benz, and Medieros of Scott Research at Chester. Harsh chemical pulps, made principally on the West Coast, introduce undesired properties in tissues. Scott Research has established that these can be overcome through the introduction of % asbestos fiber in the furnish. They found also that long, fine, fibers are more effective than short ones for the purpose. By long fibers they mean the plus 14 mesh McNett fraction. Beyond these points they have not fully developed any concrete information. Tonnages involved at 5% usage are estimated at 20,000 to 25,000 tons per annum. ( This project is active in their Research but it will require obviously three to six months at least before sufficient information is built up to support a recommendation for a commercial trial. It will be desirable to keep in close contact with Scott during this development because regular grades of fiber will not meet their needs and, if the use is to materialize, special fiber will have to be prepared for them. Various aspects of the use of asbestos were discussed. These may be classified into (1) factors having a bearing on product quality, (2) considerations involved in manufacturing process, (3) possible problems in use, (4) cost. \ (1) Product Quality Tissues must be free of specks of dark substances. The sheet must be no higher than 30, and preferably average around 8, on a TAPPI speck uount. This means that there should be no more than this number per hundred square meters of paper. The magnetite in our fiber alone would make it very difficult to meet this requirement. The size of the particle is important. A 40 or 50 mesh speck would be readily apparent in the sheet, while something in the 200 to 300 mesh range probably could not be detected. However, there is another objection to such fines, namely, they reduce the brightness of the sheet. The inclusion of excessive fines in the tissue results in dusting. There is a consumer resistance to dusty tissues. Summarizing, an ideal fiber for this application should be substantially free of magnetite or dark granular material readily apparent in the tissue. It should be as white as possible, preferably in the range of 50 to 60 6.E. brightness. It should have a high +14 mesh fraction and this fiber must be well opened. Any pencil content would be harmful. (2) Manufacturing Process The pulps are shipped to main converting plants such as Detroit, Michigan; Waterville, Maine; and Chester, Pa. In the pulping process centrifugal cleaners are used and these would remove specks from the asbestos. It is understood that cleaners are not used ahead of the converting machines in the paper mills. It would involve a substantial investment to so equip the mills. Therefore, it may be more desirable MT06111 Page No. 2 to add the asbestos to the chemical pulp in the puln mill and remove objectionable ingredients at this point. This, would involve doubling freight rates but still may be economically sound. Some of the samples of fiber submitted were fractionated by Scott with the following results: On 14 On 2? On 48 Passed AX2494M (6D Bauer ground) 5R21 AX2395M (7R Bauer ground) 5K04 Groundwood Pulp 1.8* 2.3 0 14.7 0 3.856 5.5 0.5 7.4 7 to 12 4.8* 5.6 1.7 5.7 25 90* 87 78 72 65 The data on groundwood pulp gives an upner limit on fines tolerance from an operating angle. The paper machines operate at 2500 ft/min. and they cannot tolerate reduction in drainage rates. Fines are the most important determinant in this and therefore a 65* limit of -4? mesh material is indicated. The retention of stock on the fourdrinier wire is very low in their operation. Approximately 5056 goes through the wire. This is recirculated in the white water and the excess white water goes to the saveall system. The point was made that if the asbestos is too fine it will build up in the white water and will not be retained percentagewise in the sheet. Increasing concentration in the white water would then slow up the stock on the paper machine. Such action would build up only until an equilibrium point was reached. Facts of this type only could be determined through commercial operation. The possible action of asbestos in the saveall system was touched on briefly. They use two different fiber recovery systems in series. The first units are filters (Waco) in which the water to be clarified is passed through a preformed web of tissue pulp. The second unit is a Bulkley-Dunton flotation saveall wherein the water containing very fine suspensoid - almost colloidal - is treated with a frothing agent which, due to infused air, causes the fines to float and enable them to be skimmed off. The question was asked whether asbestos would possibly interfere with either operation. In the case of the Waco, again excess asbestos fines is a potential slowing agent. However, the pulp fines also have very poor drainage qualities and our opinion is that asbestos would not be likely to be noticed in this stage. Lack of knowledge of the flotation chemicals and procedures made it impossible to obtain anything tangible in this step. However, our experience with flotation chemicals in vacuum saveall operation indicates that recovery of the asbestos fines in this stage would be comparable with cellulose. It might be added that fillers, some of them silicates, are reclaimed along with pulps in this type of saveall equipment. It is with pulps in this type of saveall equipment. It is believed that the saveall problems do not present a likely obstacle if the fines content is not excessive. On refining of the fiber, beaters and jordans are available at the paper mills and disc refiners are used at the pulp mills. Here again the pulp mill equipment is more desirable as the disc refiner will generate less fines than either the beater or Jordan. A cushioning action may be obtained from chemical pulp in passing through the jordans ahead of the paper machine. This has been indicated in some of their experimental work to date. MT06112 * ci^c ii w s The adhesiveness of the tissue sheet to the Yankee dryer on the paper machine is an important factor in creping. Whether this will be comparable to straight pulp sheets is yet to be found out. Good adhesion is desirable and our experience at Tilton is that asbestos should stick quite well to the chromium dryer drum surface. The reduction of the jumbo rolls of tissue to small consumer rolls involves high speed slitting operations. The question of wear and tear on the slitters was brought up,, It is our opinion that no difficulties should be encountered in this step as long as the fiber is free of magnetite and granular inclusions. Also the matter of health hazard connected with slitter dust in the mill was discussed. The present operation causes occasional nasal blocking and the possibility of silicosis develop ment from the dust must be satisfactorily resolved with their Industrial Relations Department. It was suggested that when the project is further along that their people contact our General Headquarters Industrial Relations Department for available information on the subject. (3) Problems in Use The main topic under this heading was the action of asbestos in septic systems. The fact that decomposition would not be likely could be used against their product. They have already encountered considerable sales resistance with their high wet strength tissues because they do not break up readily and may cause plugging of sanitary systems. There does not appear to be anything to do to asbestos to over come this obstacle. Whether or not it is a real or imaginary one appears to be an open question. (4) Cost There are a number of chemical softening agents which, Scott reported,will make a harsh pulp soft. These materials have several disadvantages, the chief ones being cost and greasiness of feel in sheets containing them. These materials cost 35 cents per pound and up. We were not informed as to the percentage required to get a soft sheet. However, it was indicated that asbestos at $93 per ton delivered would be more desirable cost-wise. This price is about the same as their chemical pulps cost them and as long as it is not exceeded, asbestos is in an acceptaole position. The cost angle is further emphasized in connection with the manufacture of the pulp itself. It is possible to produce soft pulps from Western woods by lower yield cooking procedures. The use of such processes would increase costs and also lower output. Scott is in a position where they are having difficulty meeting sales requirements and production is several weeks behind.' Nfy opinion in the overall is there is better than an even chance that this use can be developed either with clean fiber at the converting mill or with a suitable magnetite containing grade at the pulp-mill. I think it unlikely that an acceptable grade can be made to sell for a 6D price. I would suggest that the following specifications be discussed with those involved in asbestos fiber development: 1. Magnetite content less than 1$ and all below 100 mesh. 2. Same for rock content. 3. Fines minus 48 mesh - 65$ maximum. 4. No pencils. ^ 5. Preferably 5 to 10$ of +14 mesh fine fiber. **706113 J Page No. 4 Scott is to work on the materials already supplied using a cleaner similar to that at the pulp mills. The AX2494M product looks best to them except for the high =48 fraction. I think it would be well to make sure full data are obtained on this and other materials supplied to them - otherwise trouble might develop getting back on the beam if duplication is requested. It is apparent that uniformity will be a permanent consideration in making this a volume outlet. RGQsho cc; Mo Donovan, A.F.D., Fhila. S. Collier, GH A. Bo Cummins M. S. Badollet E. R.

Two bags of this fibre (designation AX-2019-M) were submitted for evaluation. The color of the fibre was lighter than normal as a result of dust removal. The yield on washing averaged 39^, representing an appreciable increase over the 15-25jl usually obtained with 6D04 fibre. Much of this increase, however, was in the form of rock, the percentage of which was s6 high that it was not feasible to settle it out of the fibrous suspension in the washer. The washed fibre could not be used in thin paper production be cause of this high rock content. Microscopic examination of the washed fiber showed numerous, short stubby pencils. It is difficult to fiberiae such material. In paper these parti cles cause low strength as they are difficult to bind together. M-M ^ WWW ajiji an n. 3 This report consists of Summary sheet only.

E. Connor visited the Scott Paper Company for the purpose of discussing asbestos fiber in paper products, principally, tissue and toweling applications where softness and absorptivity are of primary importance. Those persons interviewed were: Mr. Earl Fox, Information Specialist Mr. Charles Hurley, Research Engineer The writer first explained that recent advances in milling technology has enabled Johns-Manville to produce cleaner, grit free fibers for the paper industry. Four >, of these products, Paperbestos #1, AX2958M, AX2950M, and AX2942M were presented to Scott along with handsheets made from the material and the test results of both the fiber and paper. Mr. Fox and Mr. Hurley closely examined the fiber samples and handsheets and then stated that both the AX295&M and AX2950M interested them. Mr. Hurley ashed if it would be possible to remove most of the +4 mesh (McNett value) material from the AX2958M as it would form fiber clots in his system. He also asked if the -200 mesh (McNett value) material could be lowered. In their words, the ideal fiber for them would contain at least 90 per cent minus 4 plus 200 mesh (McNett values) material and be free of all grit and pieces of crude. I was agreed that the writer would supply ScOtt with five pounds each of AX295&M and AX2950M. Additional work will be done on the kA in an attempt to lower both the +4 and -200 mesh fractions. If such a material can be made, a small sample will also be forwarded to Scott for evaluation. J Quality Paints - Mr. Ben Lipson Quality is presently evaluating our 7RF1 in a Joint filler application. Mr. Lipson did not appear to know what fiber properties were desirable for this application but agreed to evaluate a large batch using JM 7HF1. J. E.

D.ccv/N Special Fibers for Plastics and Tissues ^ JUL 30 1959 In the past fev weeks there has been wide-spread confusion as to the official designations for these special fibers. We have reviewed the records and have unscrambled these numbers as follows: Those designations listed in the first column are the ones which should be used and those listed in the last column should not be used. Official Designation Original Feed Incorrect Designations Plastibest 10 4T28 971, AF #971, Asbestos Plastic Fiber No. 1 Plastibest 20 6020 981, AF #98l. Asbestos Plastic Fiber No. 2 Plastibest 30 6d20 & 7R06 101, 101-1, AF #101-1, Golden Fleece Paper fiber #301 O)20 & 7R06 101, 101-I,AF #101-1, Golden Fleece At various times we have noted the number 101 or 101-1 referred to as a paper fiber. It can be seen from the above table that originally the 101 fiber was a mixture of 6020 and 7R06. As near as can be determined, the designation 101 as used today appears to refer to a special cleaned fiber which was made from an original feed of 7R06 only. Since our records do not show the 101 fiber to be made from 7R06, it would be wise to avoid the use of this number. We believe: 1. That this fiber is not a standard fiber, 2. That if it becomes a standard fiber it should be given another number and not the 101 number. We hope the above table has clarified what we believe to be the official designations for the special fibers for plastics and tissues. In summary, we believe that the designations listed under "Official Designation" should be used for the subject fibers and that the designations marked under the column "Incorrect Designations" should not be used. fap cc: (See other side) A.

SUMMARY : . X rr F?. WILLIAM-- The Golden Fleece Company was satisfied with the second lot of cleaned asbestos shorts and was willing to continue experimenting with a third lot of fiber for use in their tissue paper. In preparing this third batch in the pilot model Russum cleaner several different feed fibers were investigated in place of the cleaner-rejects used in the first two runs. These were 7R06, 7F04, and blends of 7R06 with 6D20. The latter two were satisfactory, but 7R06 produced a product deficient in +14 mesh fiber. However, the bulk of the fiber for Golden Fleece was made from cleaned 7R06 by blending cleaned 6D20 with it, which raised the +14 mesh fraction to 4.4 per cent. About 250 lb of fiber resembling a high 5D with 30.5 per cent -200 mesh fines was shipped to Golden Fleece and was judged satisfactory by them. Based on the three acceptable lots of fiber prepared so far for tissue paper, the following tentative McNett specifications are recommended: Feed Product +14M % 1.0 - 2.5 4 - 12 +100M Cum % 10 - 16 50 - 60 -200M % 80 max 28 - 31 These tests showed the feed specifications were met by a blend of 30 per cent 6D20, 70 per cent 7R06,which additionally produced the highest recovery (20 per cent). In production cleaning, however, a graded fiber would not be used and controls would be necessary to keep the feed near the upper limit of the specification for optimum efficiency of cleaning.

Material Submitted Sample Ident. No. Pl-3081 Laboratory Index No. A69-99-1 ________________ Description Ash (1800F) of dust collected May 13, 1958, during a run at the Golden Fleece Paper Mill, Greenwich, N.Y. Method of Analysis The sample was examined by X-ray diffraction and emission spectrography. Results of Analysis X-ray Diffraction X-ray No. Sample ________ Results 1349-127-1 Ash (1800F) Mica "Forsterite ' Quartz "Chrysotile fiber converts to forsterite upon ignition. Soectroeraphic Ma.ior High Magnesium Silicon Minor Aluminum Iron Potassium Small Titanium Calcium Sodium Copper Trace Nickel Manganese Chromium Barium The presence of forsterite in the ash, as found by X-ray diffraction, indicates that chrysotile fiber was present in the dust before ignition. Due to the small amount of copper found in the ash along with lesser amounts of other metals, it would appear that the alloy creping doctor blades contributed very little to the ash content of the dust. The dust ash is essentially asbestos, mica and quartz. cc: E. R. Williams (2) A. B. Cummins J. S. Parkins? R. G. Quinn' M. C.

Though over four per cent asbestos was furnished to the beater only 1.1 per cent was retained ii the sheet. The white, or drainage, water from the machine included 32.6 per cent asbestos. When this white water was passed over a Bird Saveall, most of the asbestic solids were lost through the wire of this unit. The reclaimed solids contained only 11.8 per cent asbestos. The furnish was modified so that the asbestos fiber supplanted some soda pulp, softener and starch. The sheet made with the asbestos fiber was judged to be softer than standard material. Clark softness tests resulted in a factor of 1,16 with asbestos and 1.03 without. These values check the hand tests made by operators at the mill. The run demonstrated that the retention is excessively low due to the high fines content of the asbestos. Further trials with 7D04 are not recommended.

Kelleher, Asbestos Asbestos in Tissue Papers Golden Fleece Paper Mill Your letter to Ri G. Quinn July R. Williams* Your letter to R. G. Quinn has been discussed and, on the basis of previous tests and experiences on the use of asbestos in tissue papers, we are offering the ideal target for the McNett value of the fiber for this job. +14M 20.0 Max. 15.0 Min. Cum +100M -200M I1_ 55 Min. 30 Max. - In making a tissue paper with 7E04, only 20% of the original 7D fiber is retained in the paper and 80^ is discarded. The McNett value of this 20% fraction of 7D04 is as follows: +14M % 19.5 +28M % 12.1 +100M % 26.8 +200M % 8.5 -200M Cum +100M %I______________________ 33-1 58.4 These values have been used to set up an ideal target for a satisfactory fiber for use in tissue papers. In your letter you ask us to discuss means of producing such a fiber for use in tissue papers. This request is a difficult one since so many factors are involved, some of which are not answerable at present. 1. If 7C04 is to be made first, and cleaned so that RO56 of it is thrown away and only 20% recovered, then the 7D04 price prior to cleaning must be placed at a very low value to meet the tissue fiber product value of $100 per ton as you suggest. 2. If 7D04 or any other 7D, 7F, 7K, 7M, etc. fibers are to be made in large quantities and cleaned, it will reduce the production of other Group 7 fibers. 3. It seems certain that cleaning a 6D fiber is not the answer because it will contain too much lonp fibers. Actually, th# fiber lengths desirable for tissue paper fibers is somewhere between a 10M and a 24M size by dry screening methods. MT06141 J. Go Kelleher, Asbestos -2- August 1C, 1Q56 4- If methods such as scalping and screening of Groups b and 7 fibers using 10M and 24M screens are used, you will still find the -200M fines to be within the range of 60^ to 70$_ The additional cleaning using air elutriation or water washing must be done to have a fiber to meet the ideal target. 5- If additional fiber is to be taken from the tailings to increase the quantity of Group 6, then the quantity of -10M +24M fibers will also be reduced in tails. 6. If we try to extract an ideal fiber from tails, our tests show that it could be done at a high cost. For exam,pie, we took regular mill tails of several years ago and screened them over 4 screens in series. The first screen was 8 x 8M and 24 x 24M, the second screen received the mids and screened them over a 10 x 1CM and 24 x 24M, the mids were again screened over a 10 x 10M and 24 x 24M and finally the mids of the third screen were screened over a 24 x 24M and aspirated. The undersizes were dumped, but the oversizes contained fibers that could be used for Group 6 production. The recovered aspirated fiber was 0.7^ of the original tails. It had a McNett of 756 +14M and 55% -200M. This product was then air elutriated by the Sinclair equipment and they recovered 37% as a good clean fiber. This recovery based upon the original tails would be 0.259^. The McNett test on the Sinclair recovered fiber was: Ideal Target +14M +28M %% 16.3 35.8 15 Min. +100M % 29.1 +200M % 3.8 -200M Cum +100M %%________________ 15.0 81.2 30 Max. 55 Kin. Therefore, this type of processing is possible if economical. We do not know the costs of air cleaning nor just what costs the Mines would charge to do this type of screening to recover a fiber prior to the air cleaning unit. Just as a starter using this scheme, we can visualize a temporary small set up something like the following: Three screen lines set up in parallel with four 5 x 10-ft screens in series in each line and aspiration on the last screen of each line. This would pro duce O.S. for the recovery of additional Group 6 and mids for the feed for the ait cleaner. If each line of 4 screens were fed at the rate of 5 tons per hour, then the total of 15 tons per hour of tails would produce C.105 tons of a product with a Q.S. of 5R for air cleaning. The air cleaner then must be capable of handling 210-lb per hour. If we assume the same recovery of 37$ by the air cleaner then the tissue paper fiber product would be 77.7-lb per hour with a fictitious Q.S. of 3Z This would be a ov production product of about 25C-tons per year. MT06142 J. G. Kelieher, Asbestos -3- August 10, 195b From the above preliminary calculations based upon tailings, you can see that the equipment would be costly even if the tailings are priced at zero costs and the concentrates from the screenings could oe shipped just across the Canadian border for further cleaning. Cleaning of 7D04 by air elutriation also gives a fictitious Q.S. of 3b. Therefore, some scheme of pricing the fiber product rust be set up in order to meet ycur suggested $100 per ton selling price. At the present time we have no idea on the cost of the air cleaning equipment; however, we are asking the Physics Department to study the above quantities ar.d estimate their costs on that basis. We are enclosing two samples of fiber so that you can see what a clean tissue fiber looks like. end ccs E. R. Williams A. B. Cummins C. B. Bradley R. G. Quinn D. Sinclair File M. S.

C. Kelleher \/ ' :0 rP --'S KIN PRODUCTS COMRA- ; LAWARE, HTB 6 1956 J Li a ILlL Williams Experimental runs of tissue including 2% and t& 7D04 fiber were conducted on Doeskin Products Company's No. 4 machine on 1/31/56. The No. 4 machine stock system includes a Hydropulper followed by a 36-in. Bauer Refiner and a Jordan. There is a stock chest between the Hydropulper and Bauer. The Bauer is a 36-in. double disc unit driven by two 50 H.P. motors. Throughput is between 900 and 1000 lbs per hour. The refiner is usually run with .005-in. clearance between plates and the Jordan is set to do a little brushing and no cutting on the stock. White water goes to a settling system including a flotation unit built by Infilco. This part of the system was not in operation probably due to river conditions. The water supply was highly colored and included a high content of brown colloid material. This made it advisable to spill excess white water rather than recycle it through the saveall system. Machine speeds at this time with cold water are in the range of 900 fpm. However, on regular grades the machine had been operating at 760 to 780 previous to the start of the trial runs. First batches of stock including asbestos were made up in an old Umpherson beater. Two per cent 7D04 was added. Successive beaters included L$ but due to paper machine conditions usage was cut back to 2/6. The Hydropulper was then employed for fiberizing instead of the beater. The 2% asbestos stock ran about the same as regular on the machine. The fourdrinier has micarta baffles supporting the wire instead of table rolls. There are three such supports between the stock inlet and the suction box. The sheet is substantially dewatered after passing the suction box. The couches are plain and considerable water is forced through the wire at this point. When 4/6 asbestos stock was run, the sheet was not dry on leaving the suction box and a torrent of water was forced out at the couch. This resulted in a wetter sheet going to the dryers and a reduction in machine speed to 710-720 fpm. The wire on the machine was 85 mesh bronze. Some improvement in operation resulted when the Jordan was backed off. However, head paper maker decided it would be unwise to continue at 4% because the sheet was near minimum on strength and there was some question as to whether or not it would carry through the converting units. Current specification for strength is 320 grams. The 2% sheet tested 345. The regular sheet runs between 360 and 400 grams. The freeness of the regular stock is 600 to 630 ml. With 2% asbestos this had been reduced to 550. No reading was obtained on the 4/6 but performance on the wire indicated a drop in drainage rate below that obtained at 2%, Adjustments of the refiners, both Bauer and Jordan, can compensate to some degree for the slowing of the asbestos. However, when this is done the sheet strength drops off. MT06147 Page 2 Softness comparisons were made by mill personnel and all were in agreement that the asbestos sheets were softer than regular. There are no instruments in the mill for softness tests. Several jumbo rolls were converted into towelling with results said to be equal to regular. This converting operation involves embossing two sheets together employing a steel and a composition roll. Some sticking occurred to the steel roll. This was said to be experienced when the strength of the tissue is low. (We believe formation is also a factor in this and the A% tissue was poorly formed). The tissues included a small amount of specks. The mill planned originally to make speck counts on the production. This idea was abandoned due to the small number. The brightness of the asbestos content tissues was not as high as regular but due to the presence of brown coloring matter in the water, no direct comparisons could be made. The crepe was held at 15% and the inclusion of asbestos did not alter its character. A flocculant was brought along with the fiber with the object of improving drainage through addition at the head box. There were no facilities available to dissolve the compound, Separan 2610, and a part solution - part suspension, was flowed into the stock as it entered the machine head box. There was no difference in drainage performance evidenced with the flocculant. Usage was estimated at about ,5% of asbestos fiber weight. It is possible that the river water colloids exhausted the flocculant. There was some slight change in color of the sheet when the flocculant was added. The mill planned to continue the run until all the asbestos was used up. They believe that they can use 2% regularly and are interested primarily in displacing $140 per ton bleached pulp with $85 asbestos. At 2% they estimated their asbestos requirement at 250 tons per annum. Results of the run will be reviewed by Messrs. Smith and Phillips with Mike Donovan on February 7 or 8.

Donovan's Report of 8/8/55 Attached is copy of the subject report upon which you asked for comments. . The processing of the heat treated 6D20 was too severe. This fiber will not withstand much refining action. It also is more easily rejected in centrifugal cleaning. Subjecting the fiber to these units would leave very little +48 mesh fiber. Then, following this with screening through .008" and .012" flat plates, the chances of there being any +48 mesh fiber left are quite remote. The resulting asbestos undoubtedly was all fine fraction and hence the freeness drop was excessive. There is no mention made of the mixing procedure used when the processed heat-treated 6D20 was added to the tissue pulp. The way to do this without running into clumping is to add the dilute asbestos gradually to the pulp while the latter is being well agitated. The asbestos then will be dispersed within the pulp suspension and will not have a chance to coagulate. It is also important that the asbestos suspension from the screens not be allowed to stand as it will clump together and form clots. Once they are formed there is no chance of getting them redispersed in the pulp body. It may be difficult to carry this operation out in the laboratory or pilot plant as the coagulating time of asbestos suspensions is generally a matter of seconds. To offset this action, a small percentage of a dispersant such as Marasperse, Daxad, Blancol or Polyfon T may be used. The addition of 0.5 to 0,7% of asbestos fiber weight is sufficient to prevent coagulation in asbestos suspensions 0,5% solids. The lower the consistency of the asbestos, the lower will be the amount of dispersant required. It should be mentioned that excessive addition of dispersant should be avoided as it will slow up the drainage rate of the asbestos and possibly the tissue stock itself. The optimum percentage to employ should be determined in advance by shaking up the suspension in a graduate and observing how long it takes before flocculation occurs. As to a better procedure with heat treated 6D20, I would suggests (1) No refining - run the suspension through the cleaner at low inlet pressure about 10 to 15 pounds inlet pressure instead of 40, which is standard. Add dispersing agent to the fiber beforehand and it will cut down the cleaned losses. (2) Screen through 30 to 50 cut plates. Ordinarily 50 cut is used on asbestos. For this application 30 might be more desirable but the fact that the cleaner has already substantially rejected granular and pencil content, a 50 cut might be satisfactory. In fact it might be feasible to employ the fiber from the cleaner without screening at all. (3) The reject from the cleaner, if sufficient in volume, might be opened up in the Bauer refiner and the opened fiber run through a second cleaner to improve recovery. MT06150 -2- In writing this I am assuming that the policy is to encourage interest by Scott in heat treated fiber. Our other approach would involve the use of coagulants in the tissue stock so that the slowing action of Bauer refined, cleaner treated fiber would be reduced. . RGQ:ho co? J. C.

Tha way to satisfy this potential use of fiber is as follows! 1.

Names u titles of persons interviewed* fir. Sparrow, Chales Bens, Robert V. Hadeirop Coanaantai Vithin the last couple of years this company bought the plant end tinker holdings of the Sound 'view Paper Co., near Everett, Washington. Their research group hare recently been working on problems at that location and have found that wood fibre from that location requires a long heating tine to produce proper pulp for paper asking and to secure what they call "better fomatlon" of wood fibres In paper. This results in a harsh, high tensile strength paper, i once on the basis of their experience with asbestos producing a soft "feel" and reducing paper strength they Intend to evaluate our asbestos in this application. Thqrdesire a fibre with following general qualifications. 1. Aa high fibre content as possible. 2. Aa little rock as possible, i.e. black specks and rock that would result in pull outs on paper. 3. No bundles - as close to completely opened fibre as is feasible with nilling equipment. It. Bisy would prefer to operate economically in the range of wood pulp, let $80.00 to 3100.00 per ton. (These figures are their cost. Actually such puli, on open market would be around $120 to sliiO per ton. 5. They desire efficient "debonding" by the fibre (aeb.) However, this is something that they will have to experiment with to determine desired length of fibre. If Bob ^ulnn at research has any data on the efficiency of fibre in reducing tensile strength and relation of such reduction to fibre length it would be of considerable help to the Scott men. They have produced so called "hand sheets" in the lab from AX 2li07 M. In these very am-ill bundles of fibres show up since the paner is of the facial tissue type. I am attaching one of those sheets for your observation. I am requesting for their lab evaluation, LT(AX 21*63) new mill (see below)) 5K0U ) 6C fro* new mill (see below) ) MT06169 AX 2395 M ) 25 pounds of each. The reason I pick new mill 1*T and 6 is that I understand it is low in rock, bo we have a willowed and screened 1*1 from HUl 5 u well as a similar 80 from same mill? If so I believe they would be of interest here. I am sending Bob Madeira* a few pound samples of AX 2395 M and 5*0li toe preliminary work while awaiting larger samples. Production, if they decide to use asbestos, would be at inverttt Washington, Fort Edward, N. Mobile, Alabama and Cheater, Pa. First production and majority user would be Everett, VJash They believe they will require a 1Q5S addition of asbestos to produce the results they denir Hence if it works out they would need around 25.000 tons a year at the ^verett, Washington Plant. I told thee if asbestos was what they wanted we could give them what they needed. Ve may be fortunate and have one of the samples solve their problem or if that fails, we ma; have to work out something for them. I rare hope we're foortunate. I'd appreciate comments on this.

RPH3WT NO. 13-97 'J : . page no-------------7-PE-QQ4-1 date________ 9-22-42 REQUESTED BY: PREPARATION OF SPECIAL FIBRE FOR ASBESTOS TISSUE PAPERS SUMMARY: Two hundred pounds of specially processed fibre were prepared at the Mines in accordance with Fibre Development Department Report M-GN 7-115. The object was to produce a short fibre with minimum dust content so as to increase overall yield of washed fibres. This fibre was washed in the usual manner and a yield of 54$ was obtained. This represents a large increase over the yield of untreated 6D04 fibre, which is 25$. The processing therefore was effective in removal of dust. However, much of the increased yield is rock and the washed fibre could not be used in thin asbestos paper production. It is suggested that similar processing be applied to fibre of lower rock content. Coarse granular material in appreciable percentages is objectionable.

JM development pro grams concerned with this use of JM asbestos fibers over a span of several years have indicated benefits to be gained are marginal. Reports from the paper industry on the performance of union Carbide's asbestos are varied; and vhen coupled vith our findings. Indicate that the operational and economic benefits to be derived from the development of a fiber suitable for use in cellulose papers are somevhat questionable but the following program is suggested. The initial phase of investigation will concern processing of both Coalinga and Jeffrey chrysotlle to provide fibers of relatively low grit and iron content suitable for use in cellulose paper. Both dry and wet fiber processing methods for opening and cleaning fiber will be evaluated to aid in developing new and cleaner fiber for this use. Handsheet studies will be used to define the effects of asbestos additions on sheet MT06176 -2- forming characteristics, sheet appearance, and sheet physical properties. Fiber that shows promise for use in cellulose paper vill he used In studying means for blending it with T102 to provide a product similar to Union Carbide's Asbestos "T". Asbestos "T" will serve as control in this program. The productrthat appears most promising in handsbeet studies vill be evaluated on pilot plant equipment. Subsequent phases of Investigation would Include evaluation of fiber and/or fiber products resulting from phase 1, evaluation of competitive materials to establish comparative data for applications as a pitch control or retention aid, as well as contributions to softness, opacity, and prlntablllty characteristics of specialty papers. Other phases of the project which are requested vill be carried out as potential fibers are developed for specific uses. 10. $1*0,000 11. 36 12. unknown total $60,000 MT06177  PRODUCT SPECIFICATIONS DESCRIPTIONS UNION CARBIDE UNION CARBIDE CORPORATION Mining and Metals Division 270 Park Avenue, New York, N.

Ore mined from this region is proc essed in Union Carbide's up-to-date mill in King City, California. NEW PROCESS ASSURES A HIGH-PURITY PRODUCT: Union Carbide's mill incorporates a unique process which results in a short-fiber asbestos product which is purer than any other com mercially available. During the processing cycle, each individual chrysotile fibril is fully liberated from the surrounding fibrils and entrapped impurities. Union Carbide's asbestos is: Lower in grit, magnetite, and unrefined fiber bundles. Higher in brightness and surface area--uniform in quality. UNION CARBIDE'S ASBESTOS AVAILABLE IN TWO MAJOR GRADES: Union Carbide's range of HIGH-PURITY grades of asbestos is designed to meet the needs of a number of new uses for chrysotile asbestos. A range of STANDARD grades of asbestos is competitive with the conven tionally produced Grade 7 asbestos.

Surface coverage improvement and reduced underliner show through was apparent to the Technical Super intendent and stated to be a very important quality gain. III. The customer stated that shade was much better with the asbestos; getting away from their characteristic "tattle tale" grey appearance. IV. The brightness levels obtained with improved retention due to asbestos would, without question according to the Technical Superintendent, allow the elimination of the 1% Ti02. The top liner represents 2500 lbs. per hour or 25 lbs./hr. of Ti02. At 254/lb., 600 lbs. of Ti02 per day would yield $150/day savings. Since 34/lb. luster clay was replaced pound for pound with asbestos, the actual cost of the asbestos use would be about 24/lb. or $36/day leaving this Paper Mill a daily savings of $114 or with the 22 pt. Folding Box Board being produced on this one machine 100 days per year annual savings would be $11,400 per year. V. Top liner vat overflow to the sewer was reduced to coincide with the use of 3% asbestos yielding an estimated savings of $310 per day of $31,000 annually. VI. These savings are significant. They are enhanced by improvement in the bending characteristics of heavier board brought about by the flexibility effects of asbestos.

SHOW-THROUGH REDUCTION OR TOP LINER FORMATION IMPROVEMENT was visually apparent. Using the top liner brightness divided by the bottom liner brightness as an indication of reduced show-through indicated a 20% improvement. II. Brightness of the top liner was improved 4 points (62.5 increased to 66.5 with the asbestos present). III. Smoothness (Sheffield) of the top liner was improved 16%. IV. The board samples containing the asbestos gave improved Vanceometer readings indicating better printability. Better printability should also be expected with the improved brightness, smoothness, reduced show-through and improved uniformity. This manufacturer continues to use High Purity Asbestos as a result of this work. Substantial quality gain permits the producer to reduce the weight of top liner with accompanying savings.

Variations in paper manufacturing processes are continuously studied for specific areas of application. The principal goal of technical services is to provide the assistance to paper companies which will enable them to draw real istic conclusions about the superiority of high-purity asbestos. The staff works closely with the manufacturer in mill trials and other test runs using high-purity asbestos. Extensive laboratory facilities at Union Carbide's Research Center near Tuxedo, New York provides the Technical Service staff with the necessary research back-up. MT06192 PREPARATION AND METHOD OF ADDITION OF THE HIGH-PURITY ASBESTOS FIBER TO THE FURNISH FOR THE MANUFACTURE OF PAPER 1. Method of Addition The asbestos fiber is added to the stock preparation system for homogeneous distribution in the same punnor as regular vood pulps. Bresent ex perience and information on retention properties suggests the following order of addition when using a slurry or opened asbestos fiber: a. White water b. Asbestos c. Normal order of addition for pulps d. Resin e. Filler f. fye g. Alum Suggested practice above is based on the normal makeup. Unusual deviations from the system makeup shown above should be considered as a special case. For example, if bentonite or talc were being used, normally the elimina tion of this material would be suggested. Asbestos fiber with its superior oil absorbency characteristics, as well as its high specific surface value would be more effective for pitch control properties. For furnishing Kraft or sulfite specialty grades furnish makeup should be planned for mill trials considering the individual characteristics for each system. As with all stock preparation systems for proper blending of pulps, good agitation to obtain a uniform distribution of the blend of pulp and asbestos fiber is desirable. From experience and the technology developed to date the fibrous asbestos should be treated as a pulp rather than an additive. MT06193 -2- 2. Points of Addition A. Batch Type Furnish Makeup Systems The high-purity asbestos fiber can be blended with the furnish in: 1. Hydrcpulpers 2. Slushmekers 3. Beaters (when roll is used for blending or beating) 4. Dynopulpers 5. Hi-Lo pulper 6. Pulpmaster 7. Mix tanks with good agitation B. Continuous Stock Systems When pulps and chemicals are continuously blended for furnish and chemical makeup, asbestos fiber can be dispersed at 2$ solids in Union Carbide's new pellet disintegrator. Good mechanical shear-type agitation is desirable but not absolutely essential. Experience re veals that a mixing tank vith a centrifugal pump and recirculation line vt11 provide adequate agitation for opened high-purity asbestos fiber. C. Specific Retention Applications - lye Retention Improvement With critical dye retention problems where the asbestos is to be evaluated strictly for dye efficiency improvement in the manu facture of specialty products, premixing of the asbestos and dye solu tion should be practiced. With a batch system, this is done as the first step in furnish makeup. With a continuous system a mix tank would have to be used. That is the continuously metered dye solu tions and the continuously metered asbestos fibrous slurry would be fed to a small mixing tank which could be gravity-fed to the furnish blending chest. With all applications for paper quality improvements and ma terial retention improvements, methods of incorporating the asbestos fiber should be used to allow homogeneous distribution and intimate contact. Union Carbide's new pellet disintegrator can be used if there 16 any doubt. D. pH Conditions For best dispersion asbestos fiber should be blended with the furnish in the pH range of 4 to 6 -- 5 is optimum.

Solon<jtvVJf Today I spoke with Dr. T. Boaz (202-389-6805), Executive Director, Committee on Bio logical Effects of Atmospheric Pollutants, National Research Council, as to whether or not the matter of asbcstos-containingjricial tissues had been discussed in any recent NRC meetings. While Dr. Boaz was aware of a recent resurgence of interest in the asbestos health question spawned by such matters as the Reserve Mining Tailings disposal, the use of asbestos-containing talc in cosmetics, and filtration of beer, etc., he was not personally aware of any recent discussions in NRC concerning the possible hazards resulting from the release of asbestos from facial tissues. At Dr. Boaz' suggestion, I also talked to Dr. Douglas H. K. Lee (919-549 - 8411), of the National Institute for Environmental Health Services, Durham, N.C. Dr. Lee was also unaware of any recent discussions of this matter. He, in turn, suggested that I contact the newly formed Consumer Products Safety Commission. At this juncture, I turned the detective work over to Bob Mcrcnoss of AlA. /; WCT:es MT06200 '0<M- I/I-<j6TZ '7'i yf 4TTI - ^-3 f ^ W to * "T>--. ^ ..
