' J N designing Turf Toppers, we had certain objectives in mind. We wanted a construction which would be unusually durable and have flexibility and springiness; a shoe which could be worn in wet or dry, hot or cold weather. This was quite a target and required a superior type of sole. In the midst of our search for the best material, samples of soles made of Du Pont neoprene crepe were submitted for our con sideration. Laboratory test results showed us that this material was just what we were looking for. But to be absolutely sure, we completed hundreds of wear tests on these soles. The re sults convinced us that neoprene crepe was the ideal sole for Turf Toppers." HOW WELL DO YOU KNOW DU PONT NEOPRENE CREPE? Look at these advantages listed below! They're your key to profitable new designs . . . for campus, sports and casual styles. Because neoprene crepe offers a combination of dura bility and unusual, brilliant beauty that's bound to boost "buy appeal." Permanent Shape--soles retain shape and smart appearance. Brilliant Colors--can be produced in almost any hue. Long Service Life--resists oil, grease, softening, abrasion. Freedom from Tackiness--cuts down tracking and grit pickup. Excellent Uniformity--your assurance of dependable quality. So look into the possibilities of neoprene crepe for your line. It means styles that sell. . . customers that stay sold on your shoes.

Throughout the country, farmers and ranchers are finding mil. South western livestock men arc* among those who are doing' it with chemicals. .By spraying their rangeland with the weed killing cotii|xnmd called 2,4-D, they rout, out. sagebrush, loco weed and skunk-brush -- thereby doub ling the grassland available for their cattle and sheep. What does this mean in dollars? There is still a lot to he learned about this, but hero is what (lie Colorado Agricultural Experiment Station reports: `if additional resortrdi proves ilia!, sagebrush can be coni rolled economically by chemicals, then about four lotllion ol the seven million acres ot sagebrush land in Colorado could be made* to produce $7.00 worl.lt of beef, taudi and wool per acre. The present income from this land is about; $2.00 per acre." Elsewhere, weed control with chemicals is also paying big dividends. Wherever men have attempted to manage the land, they have had to keep out un wanted plants and brush... whether on the vast prairie wheatlands or the nity-dwelter's patch of liiwn. Until the development of chemicals which would kill weeds without spoiling the land for other plants, weed con trol was a laborious and never ending (ask. Land owners bad despaired of ending the weed problem with boos, cultivators, harrows, wired-burners or even caustic chemicals. Many acres were actually surren dered to bindweed, quack grass, sagebrush, scrub oak or other weeds. Now, with chemicals, the weeds are being beaten back. Land is being reclaimed and income from land is being increased by millions of dollars. Most chemical weed-killers.'ire known by their nick names--such ns 2,4-1 J, T('A.

One of the most spectacular of these is 2,4-D,'which will Mil many weeds in certain growing crops and grasslands. without hurting, the crops themselves. The others usually can be used only where all plant growth is to be lulled--as in weed patches or in.croplands before planting or after.har vest. In some eases, the chemical can be sprayed -on the land after planting the seed and before seedlings break through the ground. ........Probably the .greatest benefit fromchemical,weed-.. - killers-*- in-increased- "food-production- at-lower-cost. The 'average"eostof using 'chemicals"to'keep"croplands"" free of weeds runs $2.50 to $5.00 an acre. This is far cheaper than hand-hoeing or machine cultivation. For such an investment in the wheatlands of Judith Basin County, Montana, 2,4-D sprays cleared 3,000 acres of fanweed and mustard. Result? The wheat yield was Increased 25 per cent, or nearly six bushels per acre. B'urtliermore, this grain was free of weed seed. So no weeds, went back in the soil.at the next .planting time. Let's look at a couple of other examples. On Illinois bottomland, corn plants too wet to cultivate were growing up in weeds. The crop looked; like a total loss. One application of 2,4-D withered the weeds, and the com paid off with yields as high as 90 bushels to the acre. .......In...

So one might suppose that nothing new could be said about it at; tills late date. But we have good news to report here. At long last, a better way has been found to apply vat colors to wool. These bright, tab-fast dyes have, been used for many'years on cotton, linen and viscose rayon. Vege table' 'fibers will accept vat colors readily*. But wool, an animal fiber, hasn't ever shown any disposition to be cooperative. Many processes have been tried--some on a mill scale--to make this fiber behave' with these dyes. Results have been satisfactory on some counts-- not so good on others, Weak shades, inability of wool to withstand processing without deterioration, have been...the. .chief. ..drawbsicks...to.the. extensive ...use. of vat... colors..on wool.................................................................... ....... To ""understand" the -processing limitations,.well... have to explain that these complex organic compounds are not like ordinary dyes, which a housewife, can . apply merely by clipping a fabric or a garment In a pan of hot water containing the coloring material. In the first place, a vat dye won't dissolve in water: a chemical reaction in a strong alkali medium is required to make it soluble. Then follows a whole series of chemical operations carefully controlled as to bath time, 'temperatures ant! concentrations of the "mate rials. used. If the work is done well, the dyed fiber comes out in a water-insoluble color that is both fast to light and laundering. For-years it has been troublesome to apply vat dyes on wool without injuring the fiber. Tl* was primarily because attempts were made to use the higher dyeing temperatures so successful on cotton. Dyeings of inferior fastness and color value resulted, INowiihaabiwhTpuh^ . .damage. to...the. liter.....even ...with. high, .concentaaton -of.. alkali, ifthe dyeing temperatures are kept relatively low, This new technique can be applied to wool "tops" and "rawstock"--and the work can be done with con ventional dyeliouse equipment, an advantage of note, But there is more good news. The Du Pont process opens the way to apply vat dyes on wool and also to obtain as much color strength as.k.normally expected when, these "Same Ryes are used on. cotton. .Thus .far color evaluations have been made for SO different "Ponsol" dyes. Results have generally been satis factory, and this work Is continuing, Du Pont labora tories are currentlyat work on the problem of applying" vat dyes to certain wool yarns as wel as to tops and rawstock. This process, together with the further development of shrink resistant wool, will make pos sible woolen gin mentis that can be washed right in tile laundry... tubs^over... and over. again, .no.....feat of.. loss of color or shrinkage. In the experimental stage, too, are processes for applying vat dyes to woolen piece goods. Of course, vat dyes are not required on wool fat al! purposes. In women's dress goods, for example, acid and chrome colors are usually satisfactory.

Now, as everybody knows, aluminum, won't form this ugly "rust. It just develops an inoffensive; whitish coating when exposed to air. Taking this and other facts into account, folks in the aluminum and enamel ing industries started wondering several years ago, "Why not put porcelain enamel on aluminum or its alloys, and get the advantages of both the hard, fused coating and the non-rrating, lightweight metal?" ......Only last fall "Ceramic Industry" magairtie was lamenting; "We are frequently asked by large process ors of aluminum gadgets and structural parts for some one to porcelain-enamel the surfaces.

Hydro fluoric acid, one of the most corrosive liquids, will cat through a glass or metal hot.tie, but not through one made of this plastic. Polythene also has Lho added benefit of being lighter than other bottling materials. : As a film or sheeting, polythene remains flexible at both high and low temperatures. It sheds water like a duck's back--a property as important in pack aging as in shower curtains. If a film used to wrap frozen poultry didn't prevent moisture loss, the meat, would soon become dry and unappetizing. If a con tainer for metal parts didn't keep out moisture, they would rust. This plastic is better in that respect than most other packaging materials. . ; The chemical structure of polythene is relatively - - simple.

However, Du Pont is increasing produc- tlon of the polymer on a large scale at its new Sabine plant in Texas.
