EspañolIt is an important variety of synthetic fibers and the trade name of polyester fiber in my country. It is a fiber-forming polymer made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction— —Polyethylene terephthalate (PET), a fiber made by spinning and post-processing.
Polyester is widely used in the manufacture of clothing and industrial products. Polyester has excellent setting properties. After the polyester yarn or fabric is shaped, the flat, fluffy shape, or pleated, etc., can still last for a long time after washing many times in use.
Polyester is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country.
Characteristics of polyester:
1) High strength, impact resistance 4 times higher than nylon and 20 times higher than viscose fiber.
2) Good flexibility. The elasticity is close to that of wool, and it can almost completely recover when it stretches 5% to 6%. The wrinkle resistance exceeds other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elasticity is 2 to 3 times higher than that of nylon.
3) Good heat resistance.
4) Good water absorption.
5) Good wear resistance. The abrasion resistance is second only to nylon, which is the best in abrasion resistance, and is better than other natural fibers and synthetic fibers.
6) Good light resistance. Lightfastness is second only to acrylic fiber.
7) Corrosion resistance. It is resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose.
8), poor dyeability.
