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.
Nylon was first used commercially in a nylon-bristled toothbrush in 1938, [5] [21] followed more famously in women's stockings or "nylons" which were shown at the 1939 New York World's Fair and first sold commercially in 1940, [22] whereupon they became an instant commercial success with 64 million pairs sold during their first year on the market.
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
Carothers invented neoprene, a synthetic rubber; [17] the first polyester superpolymer; and, in 1935, nylon. In 1924, DuPont formed Lazote, Inc., which began manufacturing synthetic ammonia using the Claude process. It eventually formed the National Ammonia Company of Pennsylvania, the du Pont National Ammonia Company, and then the du Pont ...
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".
Cotton and wool producers were not the only source for fibres, as chemical companies created new synthetic fibres that had superior qualities for many uses, such as rayon, invented in 1910, and DuPont's nylon, invented in 1935 as in inexpensive silk substitute, and used for products ranging from women's stockings to tooth brushes and military ...
Those stockings were sheer, first made of silk or rayon (then known as "artificial silk") and after 1940 of nylon. Kronenberg brand stocking from mid-20th century. The introduction of nylon in 1939 by chemical company DuPont began a high demand for stockings in the United States with up to 4 million pairs being purchased in one day.
DuPont made public in 1938 that their company had invented nylon. [1] This new invention was the first synthetic fiber, fabrics that are commonly used in textiles today. [2] In 1939, DuPont began marketing nylon monofilament fishing lines; however, braided Dacron lines remained the most used and popular fishing line for the next two decades, as early monofilament line was very stiff or "wiry ...
