The polyester fiber has the characteristics of firmness, durability, good elasticity, difficult deformation, corrosion resistance, insulation, stiffness, easy washing, quick drying and the like, and is popular among people. The polyester fiber fabric has more varieties, and besides weaving pure polyester fabrics, the polyester fiber fabric also has a plurality of products blended or interwoven with various textile fibers and polyester, so that the defects of the pure polyester fabrics are overcome, and better performance is exerted.
