Do you know what forms spandex has?

1. There are also different brightness forms in the production of spandex, usually:

Transparent, CLEAR- LUSTER:
The surface fibers are relatively smooth, so the reflection becomes transparent, the friction rate is low, the evenness is poor, and the coloring is also poor. It is suitable for the production of staple fiber materials, and
warp fabrics are used more.、

White root, DULL- LUSTER:
It is the original white, the surface fiber is more uneven, the friction surface is large, and the coloring effect is good. It is suitable for long-fiber production.

Translucent, BRIGHT- LUSTER:
Titanium dioxide and anti-slip agent are added inside, which has strong resistance to chemical agents. It is often used in swimming suits because of its anti-chlorine function.

Matte color, MATT- LUSTER:
between the white and translucent, it is matte white, suitable for knitting.
2. 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 produced together 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, theelongation 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, and denim, generally 22-235Dtex.
