Polyester Yarn T8,adopts engineering differences polyester chip respectively in the two screw melting, squeeze out together in the same composite spinning components, winding, drawing process conditions, the physical performance good, excellent compound of crimp elastic fiber. Good mechanical stretch, wearing comfortable, nearly 100% back stretch with good elastic recovery. T8 yarn has a good moisture absorption and quick drying performance. It has a strong absorption performance for various auxiliary agents, and can be processed into fabrics with high strength and anti-splash water, anti-oil and other properties. T8 yarn performance of the strong moisture absorption, the dye absorption capacity is 130% of the ordinary material, easy to dyeing, T8 fabric color bright, high color saturation. Generally, the color fastness reaches level 4-4.5.
