Polyester-cotton is a mixture of polyester and cotton, and its structure is determined by the spinneret holes. The cross-section of conventional polyester is round and has no cavity. By changing the cross-sectional shape of the fiber, special-shaped fibers can be produced. Improve brightness and cohesion. Fiber macromolecules have high crystallinity and high orientation, so the fiber has high strength (20 times that of viscose fiber) and good abrasion resistance. Good elasticity, not easy to wrinkle, stiff and good shape retention, good light resistance and heat resistance, quick-drying after washing, no ironing, good wash and wear performance
