Polyester (polyethylene terephthalate, PET) is polymerized by PTA and MEG. PET is in the form of rice grains and has various varieties. 75% is used for polyester for chemical fiber. The manufacture of polyesterChina polyester FDY Yarns manufacturers staple is according to the requirements of the textile industry. Polyester fiber is divided into two types: filament and short fiber.
The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a group. Polyester staple fiber is a short fiber of several centimeters to ten centimeters. Polyester filament
The strength of polyester fiber is nearly 1 times higher than cotton and 3 times higher than wool, so polyester fabric is strong and durable; it can be used at 70~1700C, and it has good heat resistance and thermal stability among synthetic fibers; the elasticity of polyester is close to wool. Wrinkle resistance exceeds other fibers, the fabric is not wrinkled, and has good row retention; the abrasion resistance of polyester is second only to nylon, ranking second among synthetic fibers; polyester has low moisture regain and good insulation properties, but due to low water absorption , The static electricity generated by friction is large, and the dyeing performance is poor.
