...month ago when the U.S. granted E.I. du Pont de Nemours & Co. a patent on a new product known as Fibre 66, which apparently has the elasticity rayon has always lacked (TIME, Oct. 3), chemists figured that silk might be on the verge of losing its only remaining big U.S. market-hosiery. Last week du Pont officials announced that they were considering sites for a $7,000,000 "textile yarn" plant, which will normally give work to about 1,000 employes. To the trade this meant that du Pont was ready to begin commercial production of Fibre...
Last year the rubber industry bought 283,750,000 lbs. of cotton for use in tires. Therefore when U.S. Rubber Co. and Goodyear Tire & Rubber Co. announced last August that they had developed a much stronger tire by using rayon (TIME, Aug. 15), the makers of cotton tire cord were stirred to action. Last week the biggest one of all, Bibb Manufacturing Co. of Macon, Ga., announced the result-a cotton tire cord which it claims has 25% more tensile strength under friction heat developed at high speeds than the old cotton type. A Bibb customer simultaneously announced that tests...
...When rayon appeared it was at first hoped that it would completely replace silk as raw material. It never did because, among other reasons, it lacked silk's elasticity (a rayon stocking, for example, wrinkles instead of clinging to the knee and sharp-eyed women maintained they could tell the difference at a glance). The new fibre (made of complex nitrogen compounds, among them cadaverine*), as silky as silk itself, can be produced in sizes one-tenth to one-seventy-fifth finer than silk filament, and in some sizes has 150% greater tensile strength. Its elasticity is such that...
Inventors of the new synthetic wool are two Government chemists named Stephen P. Gould and Earl O. Whittier. They produced the fiber by a method similar to that used in making rayon from cellulose. The finished product is straw-colored, resembles the best grade, washed and carded Merino wool, but will not shrink so much and is mothproof. By varying the acids used in curdling the milk they claim they can make a soft, silky grade or a hard, stronger type of yarn. Although Messrs. Gould and Whittier do not know exactly what it will cost to produce synthetic wool...
...make silk, the silk worm reduces the cellulose in mulberry leaves to a protein liquid which it spins into a cocoon. Result of man's learning to imitate this technique is the 45-year-old rayon industry. A major source for the cellulose is "dissolving pulp," wood pulp processed further than for making newsprint. Last week, the largest "dissolving pulp" company in the world, Rayonier Inc., announced "the highest earnings in the history of the company and its predecessors"-$3,124,703 for the twelve months ended April 30; this was almost a million more than for the previous...
