Spandex is generally not used alone, but is incorporated into fabrics in small amounts. This kind of fiber has both rubber properties and fiber properties. Most of them are used for core-spun yarn with spandex as the core yarn, which is called elastic core-spun yarn. The outer fiber composed of natural fiber has good hygroscopicity.

Second, only 1-10% spandex filament can be used to produce high-quality elastic yarn; third, the elastic percentage control range is from 10% to 20%, and different elastic values ​​can be selected according to the use of the product. It is easy to spin 25-2500 denier silk with different thicknesses, so it is widely used to make elastic knitted fabrics, such as socks, furniture covers, ski suits, sportswear, medical fabrics, belts, military equipment, elastic parts of space suits, etc. . As people put forward new requirements for fabrics, such as light weight, comfortable fit, soft texture, etc., the proportion of low-denier spandex fabrics in synthetic fabrics is also increasing. There are also twisted yarns made of spandex naked yarn and spandex combined with other fibers, which are mainly used for various warp knitting, weft knitting fabrics, woven fabrics and elastic fabrics.
