Polyester Fiber Polyester fiber is a modification of polyester, which improves the shortcomings of low water content, poor air permeability, poor dyeability, easy pilling and fuzzing, and easy staining of polyester. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction— —Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. Advantages: bright luster, flashing effect, smooth, flat and elastic hand feeling; good anti-wrinkle and non-ironing, good light fastness; no obvious crease after loosening the silk surface by hand. Disadvantages: The gloss is not...
