Also known as polyester fiber, it is terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials through the esterification or transesterification and condensation reaction of the fiber - polyethylene terephthalate (PET), by spinning and post-processing of the fiber. Its wrinkle resistance and shape retention is very good, with high strength and elastic recovery ability, firm temperature resistance.
