The synthetic route using lactams (cyclic amides) was developed by Paul Schlack at IG Farben, leading to nylon 6, or polycaprolactam—formed by a ring-opening polymerization. The peptide bond within the caprolactam is broken with the exposed active groups on each side being incorporated into two new bonds as the monomer becomes part of the ...
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]
Nylon, the first synthetic fiber in the "fully synthetic" sense of that term, [citation needed] was developed by Wallace Carothers, an American researcher at the chemical firm DuPont in the 1930s. It soon made its debut in the United States as a replacement for silk, just in time for the introduction of rationing during World War II.
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.
Caprolactam molecule used to synthesize Nylon 6 by ring opening polymerization. Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide.Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
The team hoped to raise awareness of the amount of nets often made from nylon plastic polluting Lough Neagh and entering the oceans each year.

Nylon stockings being inspected in Malmö, Sweden, in 1954 Following the invention of plastics by petroleum and chemical corporations, fibers could now be made synthetically. Advancements in fiber spinning actuators and control systems allow control over fiber diameter and shape, so synthetic fiber may be engineered with more precision than ...
