Description

A general name for a family of synthetic long-chain polyamide resins. Nylons are classified with system in which the word nylon is followed by a numeral indicating the number of carbon atoms in the monomer, such as nylon 6. When two numbers follow, such as nylon 6,6, the polymer was made from a diamine (first number) and a dibasic acid (second number). Nylon 6,6 was first made in the early 1930s by W. H.Carothers as a textile fiber called fiber #66; the name nylon was coined in 1938 by DuPont. Nylons are thermoplastic resins that are characterized by their excellent tensile strength, toughness, elasticity, and abrasion resistance. They have good electrical resistance but can accumulate static electricity. Nylons also have low water absorption and have of good affinity for dyestuffs. Nylon fibers are compatible with wool and cotton and are often used in blended textiles to increase wear and crease resistance. Nylons are also used paints, films, foams, and molded parts.
