Polyester fiber, also known as "polyester", is a kind of synthetic fiber formed by chemical polycondensation of organic dibasic acid and diol, and belongs to a kind of polymer compound. Its invention can be traced back to the 1930s, and it is now the most important synthetic fiber. Polyester fiber has many advantages. It has excellent wrinkle resistance and shape retention, and the clothes made of it are not easy to wrinkle during wearing, and can keep the original shape of the clothes.
Polyester fiber has high strength and elastic recovery ability, which makes the woven fabric durable and can be quickly restored to its original state. In addition, polyester fiber also has the characteristics of wear resistance and non-sticking, which makes the fabric look cleaner. Generally speaking, polyester fiber is a very practical synthetic fiber, which is widely used in textile and garment manufacturing and other fields, bringing a lot of convenience and comfort to our daily life.
Advantages of polyester fiber:
Its melting point is about 255℃, glass transition temperature is about 70℃, and its shape is stable under a wide range of use conditions, and the fabric has the characteristics of washing resistance and wear resistance. In addition, polyester fiber has excellent properties, such as resistance to organic solvents, soap, detergent, bleaching solution and oxidation. And good corrosion resistance and stability to weak acids and bases. Therefore, it is widely used to make household textiles and industrial protective clothing.
With the rapid development of petroleum industry, the raw materials for producing polyester fibers become richer and cheaper. Coupled with the progress of chemical industry, machinery, electronic automation and other technologies, the production process of polyester fiber has become more efficient. Therefore, polyester fiber has become the fastest growing and highest yield variety among synthetic fibers. By 20 10, the global polyester fiber output will reach 37.3 million tons, accounting for 74% of the global synthetic fiber.
