1.Diene elastic fiber (rubber silk)

The main chemical composition is vulcanized polyisoprene, which has good chemical and physical properties such as high temperature resistance, acid and alkali resistance and abrasion resistance.Rubber silk is an elastic fiber used in the early days. As it is mainly made into coarse yarn, it is of limited use in weaving fabrics.

The original commodity in the United States was named Spandex, which was renamed Lycra in America, Elastane in Europe, Neolon in Japan and Dorlastan in Germany.Its elasticity comes from the structure of a block copolymer network composed of so-called "soft" and "hard" segments.

The spinning methods of polyurethane include dry spinning, wet spinning, chemical reaction spinning and melt spinning.Dry spinning technology is the most common method of polyurethane production.Spandex is the earliest developed and most widely used elastic fiber with the most mature production technology.
