Polyester cotton is a mixture of polyester and cotton that is not as comfortable as cotton. Not as good as cotton on the cotton. Polyester is the largest variety of synthetic fibers. Polyester has several trade names, and "polyester" is the trade name of our country. The chemical name is polyethylene terephthalate, which is usually a chemical polymerization. Therefore, the scientific name often has "poly". Polyester is also called polyester. Structure and performance: The structure is determined by the spinning hole. The conventional polyester has a circular cross section and no intermediate cavity. By changing the cross-sectional shape of the fiber, a shaped fiber can be produced. Improve brightness and saturation. The fiber macromolecule has a high crystallinity and a high degree of orientation, so the fiber strength is high (20 times that of viscose fiber) and the abrasion resistance is good. It has good elasticity and is not easy to wrinkle. It has good straightness and shape retention, good light resistance and heat resistance. It can be quickly dried and cleaned after washing. It can wear well after washing.
