Characteristics of polyester staple fiber

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. Heat resistance: It can be used at 70～1700C, 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 is higher than that of other fibers. The fabric is not wrinkled and has good line retention. Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers. Water absorption: Polyester has low moisture regain and good insulation performance, but due to low water absorption, high static electricity generated by friction, and poor dyeing performance.
