1. High strength. Due to its low hygroscopicity, its wet strength and dry strength are essentially the same. Impact strength is 4 times higher than nylon and 20 times higher than viscose.
2. Good elasticity. The elasticity is close to the wool, and it can be almost completely recovered when the elongation is 5% to 6%. The wrinkle resistance is superior to other fibers, ie, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22 to 141 cN/dtex, 2 to 3 times higher than nylon. . Polyester fabrics have high strength and elastic recovery, so they are durable, wrinkle-free.
3. Good heat resistance and heat insulation.
4. Good wear resistance. Abrasion resistance is second only to nylon with the best abrasion resistance, and it is better than other natural fibers and synthetic fibers.
5. Good corrosion resistance. It is resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It also has strong acid and alkaline resistance, UV resistance.
