Wallace Hume Carothers (/ k ə ˈ r ʌ ð ər z /; April 27, 1896 – April 29, 1937) was an American chemist, inventor, and the leader of organic chemistry at DuPont, who was credited with the invention of nylon.
Type 6,6 Nylon 101 is the most common commercial grade of nylon, and Nylon 6 is the most common commercial grade of molded nylon. [ 94 ] [ 95 ] For use in tools such as spudgers , nylon is available in glass-filled variants which increase structural and impact strength and rigidity, and molybdenum disulfide -filled variants which increase ...
Nylon is invented and patented by DuPont [6] 1938: Nylon is first used for bristles in toothbrushes. It features at the 1939 worlds fair and is famously used in stockings in 1940: 1938: Polytetrafluoroethylene (commonly known as teflon), discovered by Roy Plunkett at DuPont. 1941
DuPont has been awarded the National Medal of Technology four times: first in 1990, for its invention of "high-performance man-made polymers such as nylon, neoprene rubber, "Teflon" fluorocarbon resin, and a wide spectrum of new fibers, films, and engineering plastics"; the second in 2002 "for policy and technology leadership in the phaseout ...

The first nylon, nylon 66, was synthesized on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station. The next step was taken by Hilaire de Chardonnet , a French engineer and industrialist , who invented the first artificial silk , which he called "Chardonnet silk".
Nylon, the first synthetic fibre, made its debut in the United States as a replacement for silk, and was used for parachutes and other military uses. [ citation needed ] The techniques used to process these fibres in yarn are essentially the same as with natural fibres, modifications have to be made as these fibres are of great length, and have ...
