Polyester performance
1. High strength: short fiber strength is 2.6~5.7cN/dtex, high strength fiber is 5.6~8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber.
2. Good elasticity: the elasticity is close to wool. When the elongation is 5% ~ 6%, it can almost be completely recovered. Wrinkle resistance is higher than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22 ~ 141cN/dtex, which is 2~3 times higher than nylon.
3. Heat resistance and thermal stability in synthetic fiber fabric comparison OK.
4. The surface of polyester is smooth and the internal molecules are closely arranged.
5. Good wear resistance: wear resistance is second only to wear resistance comparison good nylon is better than other natural fibers and synthetic fibers.
6. Good light resistance: light resistance is second only to acrylic fiber.
7. Corrosion resistance: Bleacher, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Dilute alkali resistance, not afraid of mildew, but hot alkali can make it decompose chromaticity poor, but good color fastness, not easy to fade.
