Do you know what polyester fiber is
Polyester fiber, commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and diol, referred to as PET fiber, which belongs to high molecular compound. Invented in 1941, it is currently the largest variety of synthetic fibers. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is durable, anti-wrinkle, non-ironing, and non-sticky.
With the development of organic synthesis, polymer science and industry, a variety of practical PET fibers with different characteristics have been developed in recent years. Such as polybutylene terephthalate (PBT) fiber and polytrimethylene terephthalate (PTT) fiber with high elasticity, and fully aromatic polyester fiber with ultra-high strength and high modulus: the so-called The "polyester fiber" usually refers to polyethylene terephthalate fiber.
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 255°C, and the glass transition temperature is about 70°C. It is stable in shape under a wide range of end-use conditions. The fabric has wash and wear properties. In addition, it has excellent resistance and good corrosion resistance. It is stable to weak acids and alkalis, so it has a wide range of uses and industrial uses.
The rapid development of the petroleum industry has also provided richer and cheaper raw materials for the production of polyester fibers. In addition, in recent years, the development of chemical, mechanical, electronic automatic control technology and other technologies has gradually realized short-range processes in the production of raw materials, fiber forming and processing. With the rapid development, continuity, automation and high-speed, polyester fiber has become the fastest-growing synthetic fiber variety with the highest output. In 2010, the global output of polyester fiber reached 37.3 million tons, accounting for 74% of the world's total synthetic fiber.
