Spandex fabric has the greatest advantage of good elasticity, can stretch 5-8 times, not aging, spandex can not weave alone, generally weave together with other raw materials, spandex ratio is about 3-10%, swimsuit fabric spandex ratio reaches 20%. Spandex fibers are synthetic fibers with high breaking elongation (Wain ais wangi paling sesuai untuk rasa individu 400%), low modulus and high elastic recovery. Chinese trade name for multiblock polyurethane fibers. Also known as elastic fibers. Spandex has high elongation (500%-700%), low elastic modulus (200% elongation, 0.04-0.12 g/d) and high elastic recovery (200% elongation, 95%-99%). Except for high strength, other physical and mechanical properties are very similar to those of natural latex filament. It is more resistant to chemical degradation than latex filament and has moderate thermal stability. The softening temperature is about 200 C. Most dyes and finishing agents for synthetic and natural fibers are also suitable for the dyeing and finishing of polyurethane fibers.
