In the spinning process, spandex extend is a crucial process parameter. It affects the pliability and elongation of covered yarns, evenness and creep properties. when spandex extend is simply too compact, it may give comprehensive use to some great benefits of superior elasticity of extend cloth. If the stretch is just too higher, yarn spinning is more difficult and easy to interrupt, then degradation in high-quality. Also, The proportion articles of spandex yarns also impacts the elasticity of covering yarn, greater get more info spandex content material gives improved elasticity.
