Spandex has different uses and various product forms, mainly divided into three types: bare yarn, core-spun yarn, covered or twisted yarn. Each different combination corresponds to a different purpose.

Bare yarn: It is 100% spandex yarn. Bare yarn is generally not used directly on fabrics. Most of them are co-produced with rival materials and require special equipment to produce. Knitwear is the most commonly used, such as swimwear, sportswear, etc., generally 22-78Dtex.

Core spun yarn: yarn spun with bare yarn as the core and other materials as the outer sheath, referred to as CSY. For example, using cotton core-spun yarn to insert the drafted bare yarn on the spinning car of the ring spinning machine, the elongation of the bare yarn wrapped around the core-spun yarn must be properly adjusted, and its expansion and contraction rate is suppressed to 2-3 times. Nowadays, core-spun yarn is divided into hard-core yarn and soft-core yarn. The rival materials of core-spun yarn are cotton, polyester, nitrile and so on. It is widely used in fabrics, knitwear, bandages, socks, underwear, denim, generally 22-235Dtex.
