Preliminary Dust Survey for Asbostos Textile Institute, Juno, 1947 .10 One plant has Installed ventilation for their ring spinning frames vhlch management bellevea has reduced dust In this operation. It consists In a aeries of exhaust openings under the frame, near the floor, running the -length of each frame* Tine did not permit demonstrating to our own satisfaction vhether a measurable improvement had been effected or not* this should be done by a sorles of dust measurements vith exhaust an end off* The volume of air exhaust is Insufficient to effect a true local ex haust action, end If It Is effective It must, therefore, be an effect of eimple dilution. Twisting Interest In control of dust from twisters Is widespread in the In dustry and Plants A and have installed an exhaust system like the one de scribed for the spinning frames in Plant. A. . Here again the operators believe a united Improvement has resulted. Dust count data is needed that will measure the degree of improvement. Winders Cop winders have been exhausted in Plants A and B with reports of beneficial reduction In dustiness* We do not have quantitative data on this point* The exhaust arrangement far Foster winders was developed many years ago and is veil known. The tendency to elimination of this mates - * the. problem one of little practical Interest now* ^ In most plants, dust from other equipment, such as spinning end twisting which cute cmmnnly-in the same' roam. Is of greater importance than that from winding operations.
