History

Wallace Carothers of DuPont discovered polyamide 6.6 in 1931. In October 1938 commercial production of nylon 6,6 began. The first commercial application were for the bristles for the Miracle Tuft toothbrush. The following year, nylon stockings became available and were a sensation at the World’s Fair in New York City Nylon 6 was developed in the 1940’s (largely as a consequence of the patent that existed on Nylon 6,6). With the start of World War II, nylon was then commandeered for war purposes for example, to make canopies for parachutes. Nylon for injection moulding did not begin until the 1950’s.
