Spandex is a lightweight, synthetic fiber that is used to make stretchable clothing such as sportswear. It is made up of a long chain polymer called polyurethane, which is produced by reacting a polyester with a diisocyanate. The polymer is converted into a fiber using a dry spinning technique.
Elastic material used in the fabrics of a summer cycling attire comprising a jersey, bib shorts and gloves. Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether - polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont. [1][2][3]
6 Αυγ 2022 · Spandex is a synthetic fabric that is prized for its adaptability. Contrary to popular belief, “spandex” isn’t a brand name; instead, it refers mostly to polyether-polyurea copolymer textures that have been produced using a variety of fabrication techniques.
The history of spandex begins with the study of polyurethane in 1937 in Europe in the research laboratories of Otto Bayer. In 1939, Paul Schlack obtained a high-molecular polymer that made it possible to obtain fibres with high elongation and elastic properties .
Spandex, also known as elastane or Lycra, was invented in 1958 by chemist Joseph Shivers at DuPont. It quickly gained popularity for its exceptional elasticity and strength, making it a popular choice for athletic wear and other stretchy garments.
