Nylon

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins.

History

Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1927. The first example of nylon (nylon 6,6) was synthesized using diamines on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station.

Properties

Nylon is a strong, light material that is also somewhat resistant to heat, UV rays, chemicals, oils, and weathering. It has excellent abrasion resistance and can be dyed in a wide range of colors.

Uses

Nylon is used in a wide variety of applications, including apparel, rugs and carpets, upholstery, automotive parts, ropes, and more.

Production

Nylon is produced by reacting diamine and dicarboxylic acid. This reaction results in the formation of a polymer chain and the release of water.

Environmental Impact

Nylon production is a significant contributor to environmental pollution, including the release of nitrous oxide, a potent greenhouse gas.
