Another Nylon? To rebound, Du Pont still puts its faith in its prolific test tube. Among other promising ventures, it has recently developed a cheap but strong plastic heat exchanger, a line of nylon shutters and plastic vanity tops, and a compound called Zeset that keeps wool sweaters shrinkproof and enables felt hats to retain their shape and stiffness. For the future, Du Pont researchers envision such wonders as ski jackets that grow thicker and warmer when the temperature drops, curtains that change color or covering power when the sun hits, a fiber product that will remove salt or waste...
...lead time in this field," he says, "and we intend to keep it." Koratron has lately extended its process to knitted goods, sponsors studies at the Stanford Research Institute to explore additional uses. It is also cooperating with Department of Agriculture chemists in experiments to find a way to shrinkproof and permanently crease wool, one fiber that still resists artificial processing. If the researchers succeed, men will one day be able to toss wool suits into washers, put them on again without ironing...
...that looks like a shower head to form filaments-but its molecular structure has been changed through the use of new chemicals in the manufacturing process. Whereas the old rayon shrank in the rain and often broke up in the family washing machine, the new fiber is stronger and shrinkproof, while retaining the absorbent qualities of the old fiber. Nowadays it is usually blended with a cheap grade of cotton to produce such items as bed sheets that feel like percale and towels that can be dyed brilliantly and absorb more water than cotton. Because of Government supports that...
