Assalamu alaikum.I study all article which you make by large amount of study, All are essential practical in your textile relevant routines.Might Allah bless you for continuing.

The spandex covered yarn produced by our company is actually a type of textile product. It is typically produced by wrapping spandex fibers throughout the floor of other fibers, normally cotton, polyester, nylon, etc.

During the spinning process, spandex extend is a crucial process parameter. It influences the flexibleness and elongation of covered yarns, evenness and creep Homes. when spandex stretch is too compact, it may give entire use to the benefits of excellent elasticity of stretch cloth. If the stretch is too superior, yarn spinning is more challenging and simple to break, then degradation in quality. On top of that, The proportion material of spandex yarns also affects the elasticity of covering yarn, bigger spandex information provides better 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 great extent and also the core exposure is less, and since the outer wrapped filaments are wrapped with reverse spiral angles symmetrically within the Main filaments, the elasticity on the wrapped yarn is properly balanced and may usually be processed within the later process without shaping procedure, though the processing expense of double wrapped yarn is increased. It is principally used for elastic fabrics such as leg guards, elastic belts, sock openings and tights.
