1, the wear resistance of polyester is stronger than that of acrylic.
2. Acrylic fiber is called artificial wool. It is soft, fluffy, easy to dye, bright in color, light-resistant, antibacterial and moth-proof. Its textiles are widely used in clothing, decoration, industry and other fields, with poor alkali resistance.
3. Polyester has high strength. Because of its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber. Good elasticity. Elasticity is close to wool, and it can be almost completely recovered when stretched by 5% to 6%. The crease resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. Heat resistance and thermal stability are the best among synthetic fiber fabrics. Polyester has smooth surface and tight internal molecular arrangement. Good wear resistance. Wear resistance is second only to nylon with the best wear resistance, and superior to other natural fibers and synthetic fibers. Good light resistance. Light resistance is second only to acrylic fiber. Corrosion resistance. Resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Dilute alkali resistance is not afraid of mildew, but hot alkali can decompose. The dyeability is poor, but the color fastness is good and it is not easy to fade.
