Nylon is the name of a family of synthetic polymers that are commonly used to make a variety of different types of apparel and consumer goods. Unlike other organic or semi-synthetic fibers, nylon fibers are entirely synthetic, which means that they have no basis in organic material. The use of this type of synthetic polymer in clothing began with a desire to find alternatives to silk and hemp for parachutes in World War II. At the time the war began, cotton was used for more than 80 percent of textile applications in the United States, and almost all other textiles were made from wool.
What is Nylon Fabric: Properties, How its Made and Where

Nylon is a synthetic polymer, a plastic, invented on February 28, by Wallace Carothers at the E. The material was announced in and the first nylon products; a nylon bristle toothbrush made with nylon yarn went on sale on February 24, and more famously, women's stockings went on sale on May 15, Nylon fibers are now used to make many synthetic fabrics, and solid nylon is used as an engineering material. Chemically, nylon is a condensation polymer made of repeating units with amide linkages between them: hence it is frequently referred to as a polyamide. It was the first synthetic fiber to be made entirely from inorganic ingredients: coal, water and air. These are formed into two intermediate chemicals, most commonly hexamethylene diamine and adipic acid a dicarboxylic acid , which are then mixed to polymerise. The most common variant is nylon 6,6, also called nylon 66, which refers to the fact that both the diamine and the diacid have 6 carbon backbones.
A generic name for any manufactured fiber in which the fiber-forming substance is any long chain synthetic polyamide having recurring amide groups -NH-CO as an integral part of the polymer chain Federal Trade Commission definition. Nylon 6,6 was first made in the early s by W. Carothers as a textile fiber called fiber 66; the name nylon was coined in by DuPont. By , nylon 6,6 and nylon 6 were being commercially produced in the US and Germany, respectively. Nylon 6,6 and nylon 6 are still the most common nylons used in fibers.
Made from a soft, lightweight combination of nylon and spandex, it offers UPF 50 protection for sunny days when I want a little extra shielding from the sun between sets. Instead of traditional sidearms, the company uses a thin nylon strap to hold them on your face, like a permanent version of sunglasses straps that you can tighten. This chemical carried the acid out of the nylon thread as it dried.
