origin
Polyurethane Fibre is called PU fiber for short. There are two varieties. One is an aromatic bis-isocyanate and a hydroxyl-containing polyester chain segmented copolymer, abbreviated as polyester spandex, and the other is an aromatic bis-isocyanate. Hydroxy polyether segment mosaic copolymer, referred to as polyether spandex. The representative trade name of polyester spandex is Vyrent, and the representative trade name of polyether spandex is Lyera.
The main performance
Spandex fibers usually have elongation of 500% to more than 700%, and the elastic recovery performance is good. Retract at 97% at 200% elongation, and retract at more than 99% at 50% elongation. The difference in the relative density of various spandex is small, generally 1.20 to 1.25, and the breaking strength is 4.41 to 8.82 cN/tex (0.5 to 1.Og/denier). The strength of polyester spandex is low. Polyether spandex strength is higher.
Spandex fiber moisture absorption rate is generally 0.3% -1.2%, multifilament moisture absorption rate is slightly higher than the monofilament, heat resistance is generally 95 ~ 150 °C when stored for a short time will not damage the fiber, safe ironing temperature Below 150°C. The fiber burns slowly and forms a gelatinous residue after combustion. Excellent dyeing performance, can dye a variety of colors, strong affinity for dyes. Good acid and alkali resistance, able to bleach, no mildew.
use
Spandex can be used for garments that require stretch to meet the comfort requirements. Such as:

Spandex is used in a smaller proportion of general clothing. In North America, it is rarely used on men's clothes and more on women's clothes. Because women's clothes are required to be more close. In use, other fibers such as cotton and polyester blends are added in large quantities to minimize gloss.
