Experimental stockings

Union Hosiery Co. · ca 1937

In 1928, the E. I. DuPont de Nemours Co. hired Wallace Carothers Ph. to conduct pure research in any area of chemistry he chose. His interest was in the construction of long chain polymers, similar to those found in nature. There was no product in mind when he and his team began their work, they simply wanted to learn as much about large molecules as possible. The work done by Carothers and his team lead to the discovery of polyesters and polyamides. DuPont went with the polyamides, and nylon was born. It was the first fiber produced entirely in the laboratory, and was introduced to the public in the form of women's stockings at the 1939 World's Fair. Nylon stockings went on sale May 15, 1940, and were a smashing success. Prior to the production of nylon stockings, American women wore stockings made of silk or rayon. By 1942, nylon stockings were taking twenty percent of the stocking market. With U.S. entry into World War Two, nylon was declared a defense material and withdrawn from the civilian market. Nylon's most famous use during the war was as a replacement for silk in parachutes. However, it was also used in ropes, netting, tire cord, and dozens of other items. So many uses were found for nylon that some referred to it as the "fiber that won the war." When the war ended, nylon stockings were brought back and quickly replaced silk and rayon in the stocking market.
