Characteristics and uses of polyester fiber

Characteristics and uses of polyester fiber

Strength: The strength of polyester 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, it 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.

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 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., and is widely used in various clothing and decorative materials. In industry, polyester can be used for conveyor belts, tents, canvas, cables, fishing nets, etc., especially polyester cord used for tires, which is close to nylon in performance. Polyester can also be used for electrical insulation materials, acid-resistant filter cloth, cloth for the medical industry, etc. 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.
