On the market, elastic fabrics are predominantly designed making use of SCY by using a Z twist. Nonetheless, for solutions like socks and underwear, an S twist is often chosen because of the exclusive needs of overall body structure.

The phenomenon of deformation with time under the action of a continuing draft power is called creep. When the plan spandex yarn is pre-drawn 3.5 occasions, the creep resistance is finest. It ought to be especially modified according to the usage tone as well as form of its downstream fabric.

There are 2 purposes of covering a yarn: one demands an elasticity which normal textile yarn are not able to provide although a person would nevertheless like to maintain the apperance of the textile yarn.

Though SCY has reduce core exposure, typically more unlikely to lead to excellent complications in spinning and weaving, aside from uneven twists, having said that, its production efficiency is reduced. Therefore, the price is greater than RMB 5000/T larger than the identical regimen of ACY. The price of FDY is a lot more than RMB 10000/T larger than the identical schedule of ACY. Consequently it significantly increases the cost of utilizing the SCY.
