The polyester fiber has the advantages of good crease resistance and shape retention, high strength and elastic recovery capability. It is firm and durable, has the functions of resisting wrinkle, preventing ironing and preventing hair from sticking. Polyester (PET) fibers are synthetic fibers spun from a fiber-forming polymer formed by ester-linking of individual links in a macromolecular chain, and polyester is abbreviated to PET. The polyester fiber has a series of excellent properties, such as high breaking strength and elastic modulus, moderate rebound resilience, excellent heat setting effect, and good heat resistance and light resistance. Polyester fibers have a melting point of about 255 ℃ and a glass transition temperature of about 70 ℃, are stable in shape under a wide range of end-use conditions, and are widely used for clothing and industrial purposes because they have excellent resistance (e.g., resistance to organic solvents, soaps, detergents, bleaching solutions, and oxidizing agents) and corrosion resistance, and are stable to weak acids and alkalis.
