It is completed by low-speed spinning and high-speed drawing and winding on a spinning and drawing combined machine.polyester FDY Yarns manufacturers
Polyester is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming polymer made of 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.
