Hollow polyester filament hollow FDY 

Characteristics of polyester filament Strength: 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. Dope Dyed Polyester Filament Yarn Heat resistance: It can be used at -70℃～170℃, which is the best heat resistance and thermal stability among synthetic fibers. Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds that of other fibers. The fabric does not wrinkle and has good shape retention. Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers. Water absorption: polyester has low water absorption and moisture regain and good insulation performance, but due to low water absorption, large static electricity generated by friction, and poor natural adsorption performance of dyes, polyester is generally dyed by high temperature and high pressure dyeing method. Dyeability: Polyester…
