2.Synthetic Fiber
3） Acrylic Fiber
- Acrylic fiber is a domestic trade name, and its scientific name is polyacrylonitrile fiber. Foreign countries are also known as “Aolun”, “Cautel”, “Delain” and so on.
Acrylic is white, curly, fluffy, soft to the touch, resembles wool, and is often used in blends with wool or as a substitute for wool, so it is also known as “synthetic wool.” Acrylic fiber is not hygroscopic enough, but its wettability is better than wool and silk fiber. Its abrasion resistance is poor in synthetic fibers, and the ironing temperature of acrylic fibers is below 130 °C.
4）Velon
- Velon’s scientific name is polyvinyl formal fiber. Foreign countries are also known as “Vinnel”, “Vinal” and so on.
Vinyl is white as snow and soft like cotton, so it is often used as a substitute for natural cotton. It is called “synthetic cotton”. The hygroscopic properties of vinylon are the best in hygroscopic properties of synthetic fibers. In addition, the abrasion resistance, light resistance and corrosion resistance of vinylon are good.
5）Polyurethane
- Polyurethane has a scientific name called polyvinyl chloride fiber. There are “Tianmeilong” and “Rowell” in foreign countries.
Polyurethane has many advantages and strong chemical resistance; thermal conductivity is worse than wool, so it has strong heat preservation; high electrical insulation and flame retardant.
The disadvantages of the chlorinated fiber are also outstanding, that is, the heat resistance is extremely poor.
6）Spandex
- Spandex is known as polyurethane elastic fiber. It is also known as “Lecquer” and “Spanzier”. It is a chemical fiber with special elastic properties, which has been industrially produced and is the fastest growing elastic fiber.
Spandex is excellent in elasticity. The strength is 2 to 3 times higher than the latex yarn, the linear density is finer, and it is more resistant to chemical degradation. Spandex is good in acid and alkali resistance, sweat resistance, seawater resistance, dry cleaning resistance and wear resistance.
Spandex fibers are generally not used alone, but are incorporated into the fabric in small amounts, such as plied with other fibers or made into core spun yarn, for weaving stretch fabrics.
7）Polyolefin
- elastic fiber, polyolefin elastic fiber is made by melt spinning of thermoplastic elastomer, can withstand high temperature of 220 ° C, has chlorine bleaching resistance and strong acid and alkali treatment, and has strong resistance to UV degradation. New elastic yarn.
