During the spinning process, spandex stretch is a vital process parameter. It has an effect on the flexibility and elongation of covered yarns, evenness and creep Qualities. when spandex extend is simply too little, it can provide whole use to some great benefits of great elasticity of stretch material. If the extend is simply too higher, yarn spinning is harder and simple to interrupt, then degradation in high-quality. In addition, the percentage material of spandex yarns also influences the elasticity of covering yarn, better spandex written content presents improved elasticity.
The double-covered yarn has two outer levels of filaments or yarns wrapped round the spandex Main, and these two layers are typically in opposite directions. The core spandex is covered to a good extent and the Main publicity is a lot less, and since the outer wrapped filaments are wrapped with opposite spiral angles symmetrically throughout the core filaments, the elasticity from the wrapped yarn is nicely balanced and will commonly be processed from the later on process without shaping remedy, however the processing cost of double wrapped yarn is bigger.
