Polyester staple fiber is a short fiber of several centimeters to ten centimeters.

Characteristics and uses of polyester staple fiber

Strength: The strength of polyester staple fiber is nearly 1 times higher than cotton and 3 times higher than wool, so the 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 better than 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.

Polyester staple fiber is used as clothing fiber, and its fabric can achieve the effect of no wrinkle and ironing after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., which are widely used in various clothing and decorative materials. In industry, polyester can be used for conveyor belts, tents, canvas, cables, fishing nets, etc., especially for the polyester cord used in tires, which is close to nylon in performance. Polyester can also be used for electrical insulating materials, acid-resistant filter cloth, and medical industry cloth. Synthetic fibers are widely used in various fields of the national economy because of their high strength, abrasion resistance, acid resistance, alkali resistance, high temperature resistance, light weight, warmth retention, good electrical insulation and resistance to mildew.
