Spandex was at first intended to be considered a synthetic replacement for purely natural latex rubber. Bayer Fibers generated their brand name of spandex under the identify of Dorlastan.
Throughout the spinning process, spandex extend is a vital process parameter. It affects the pliability and elongation of covered yarns, evenness and creep Homes. when spandex stretch is simply too tiny, it can give whole use to the advantages of superior elasticity of extend fabric. If the stretch is simply too large, yarn spinning is more challenging and simple to break, then degradation in excellent. Furthermore, The share articles of spandex yarns also affects the elasticity of covering yarn, better spandex content material presents much better elasticity.
The double-covered yarn has two outer levels of filaments or yarns wrapped throughout the spandex core, and both of these levels are typically in opposite Instructions. The Main spandex is covered to an excellent extent and also the Main publicity is much less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically across the core filaments, the elasticity with the wrapped yarn is properly well balanced and may generally be processed during the later on process without shaping therapy, though the processing price of double wrapped yarn is greater.
