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.
Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural or synthetic fibres. [1] [2] [3] Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be ...
Nylon 66 can also be produced at laboratory scale in this way. Representative procedures and equipment lists for conducting the nylon rope trick demonstration are available in literature procedures. [2] The nylon rope trick was developed as a scientific demonstration by American chemist Stephanie Kwolek, who later invented Kevlar aramid. [3]
Exemplified by the twisting of a long, narrow box, the Wright brothers incorporated wing warping on their 1899 glider that used ropes to pull on the wings. Later on, the young French engineer Robert Esnault-Pelterie replaced wing warping in 1904 with the aileron on a copy he made of a 19th-century Wright glider.
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 ...
One of the spin-offs from this work was the development of the first nylon climbing rope. [23] In 1946 he was involved in Operation Musk Ox as a civilian observer for the Army Service Forces. [22] [24] House was elected an Honorary member of the American Alpine Club. [10] He died on December 18, 1997, in Peterborough, New Hampshire. [25] [9]

Nylon was introduced by DuPont around 1939 and was in extremely high demand in the United States, with up to 4 million pairs of stockings bought in one day.During World War II, nylon was used extensively for parachutes and other war materials, such as airplane cords and ropes and the supply of nylon consumer goods was curtailed.
