The structure and properties of polyester fiber

Polyester fiber is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol. It is a high-molecular compound, and its trade name is polyester. The polyester fiber is durable, wrinkle-resistant and non-sticky. Wool is mainly used for clothing and interior decoration. Its biggest advantage is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. As the large-scale industrial production of polyester fibers is all PET fibers, the said polyester fibers mostly refer to PET fibers unless otherwise specified.
