The Main spandex is covered to a great extent as well as core publicity is considerably less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically round the core filaments, the elasticity on the wrapped yarn is very well balanced and may commonly be processed in the later course of action without the need of shaping therapy, but the processing cost of double wrapped yarn is larger. It is principally employed for elastic fabrics for example leg guards, elastic belts, sock openings and tights.

Fulgar polyamide protects the LYCRA® fiber from have on and friction guaranteeing a longer life of the clothes.
Throughout the spinning system, spandex stretch is an important course of action parameter. It impacts the flexibility and elongation of covered yarns, evenness and creep Houses. when spandex stretch is simply too tiny, it may give entire use to the advantages of fantastic elasticity of stretch cloth. Once the extend is too significant, yarn spinning is harder and straightforward to break, then degradation in high-quality.
