Nylon is a family of synthetic polymers with amide backbones, usually linking aliphatic or semi-aromatic groups. Nylons are white or colorless [1] [2] and soft; some are silk-like. [3] They are thermoplastic, which means that they can be melt-processed into fibers, films, and diverse shapes.
Manufactured cellulose fibers come from plants that are processed into a pulp and then extruded in the same ways that synthetic fibers like polyester or nylon are made. Rayon or viscose is one of the most common "manufactured" cellulose fibers, and it can be made from wood pulp.
Nylon is a fibre used to imitate silk; it is used in the production of pantyhose. Thicker nylon fibres are used in rope and outdoor clothing. Spandex (trade name Lycra) is a polyurethane product that can be made tight-fitting without impeding movement. It is used to make activewear, bras, and swimsuits.
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 .
Called O-Cycle, Fulgar’s new nylon 6.6 yarn is crafted from tire cord waste. It’s the result of a partnership with Germany-based public company Basf, which provided the technology to turn ...
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.
Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1.9% weight variation after 25 weeks of submersion in water in comparison to 2.2-2.7% elongation variation and 9.5% weight variation for Nylon 6.
