1. High strength. The strength of short fiber is 2.6 ~ 5.7CN /dtex, and that of high strength fiber is 5.6 ~ 8.0CN /dtex. The strength in wet state is basically the same as that in dry state. Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber.
2. Good elasticity. Elasticity is similar to wool, and when extended by 5% to 6%, it can recover completely. Crease resistance is far more than other types of fiber, that is, the fabric does not crease, scale stability is good. Elastic modulus, 2 ~ 3 times higher than nylon. It has good elasticity and is perfect for women's wear. In recent years, the popular stretch women's leggings can also be used for shoes and hats, home textiles, toys, crafts and so on.
3, good heat resistance, high temperature will not deformation. Good light resistance. Light resistance is second only to acrylic fiber. External lubrication, internal molecules placed tightly, the lack of hydrophilic structure between molecules, so the moisture return rate is very small, poor hygroscopic function.
4, corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum commodities and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make its differentiation.
5, good wear resistance. Wear resistance is second only to the best wear resistance of nylon, than other natural fibers and synthetic fibers are better
