详情

Polyester fiber has a series of excellent properties, such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting effect, good heat resistance and light resistance. The melting point of polyester fiber is about **5 ℃, and the glass transition temperature is about *0 ℃. The shape of polyester fiber is stable under the conditions of a wide range of end uses. The fabric is washable and wearable. In addition, it has excellent impedance (such as resistance to organic solvents, soap, detergents, bleach, oxidants) and good corrosion resistance. It is stable to weak acids, alkalis, etc., so it has a wide range of uses in clothing and industry. The rapid development of the petroleum industry has also provided more abundant and cheap raw materials for the production of polyester fiber. In addition, the development of chemical, mechanical, electronic automatic control technology and other technologies in recent years has made the process of raw material production, fiber forming and processing gradually realize short distance, continuous, automatic and high-speed. Polyester fiber has become the synthetic fiber variety with the fastest development speed and the highest output. In ***0, the global output of polyester fiber reached *7.3 million tons, accounting for *4% of the world's total synthetic fiber
