Polyester fiber, commonly known as "polyester". It is a synthetic fiber made of spun polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, and belongs to high molecular compound. It was invented in 1941 and is the current variety of synthetic fibers. The advantages of polyester fiber are that it has good wrinkle resistance and shape preservation, and has high strength and elastic recovery ability. Durable, wrinkle resistant, not hot, not sticky.

Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent thermal setting effect, good heat resistance and light resistance. The melting point of polyester fiber is about 255℃, and the glass transition temperature is about 70℃. Its shape is stable under a wide range of conditions of use, and the fabric is washable and wear-resistant. In addition, it also has excellent corrosion resistance (such as resistance to organic solvents, soaps, detergents, bleach, oxidants) and good corrosion resistance, stable to weak acids, alkalis, etc., so it has a wide range of food and industrial uses. The rapid development of the petroleum industry has also provided more abundant and cheap raw materials for the production of polyester fibers. In addition, in recent years, the development of chemical engineering, machinery, electronic automatic control technology and other technologies has gradually realized the short-term process of raw material production, fiber molding and processing. Polyester fiber has become a synthetic fiber variety with rapid development and high yield. In 2010, global polyester fiber production reached 37.3 million tons, accounting for 74% of the world's total synthetic fiber production.
