Polyester fiber can be divided into two types: long yarn and short fiber. Generally, the polyester filament refers to a filament having a length of more than a kilometer, and the filament is rolled up into a mass. Polyester staple fiber refers to short fibers of a few centimeters to a dozen centimeters. However, both polyester filament and polyester staple fiber have the characteristics and uses of polyester fiber, including the following:
The characteristic strength of polyester fiber: Compared with ordinary cotton, polyester fiber has a strength of about 1 times higher than that of ordinary wool, so polyester textile articles are very durable.
Heat resistance: Polyester fiber can be used in the environment of 70 to 1700 ° C, which is the best heat resistance and thermal stability of synthetic fiber.
Elasticity: The elasticity of polyester is similar to that of wool. The wrinkle resistance is higher than that of other fibers. The textile articles do not wrinkle and maintain excellent shape properties.
Abrasion resistance: The abrasion resistance of polyester fiber is only lower than that of nylon, ranking second in synthetic fiber.
Water absorption: Polyester fiber has very low water absorption and moisture repellency and excellent insulation performance. However, because of its low water absorption performance, the static electricity generated by friction is relatively large, and the dyeing performance is not good.
Use of Polyester Fiber Polyester fiber is commonly used as a fiber for clothing. His textile article does not wrinkle after washing and does not require ironing. Polyester and various types of fibers are usually mixed and woven or interwoven, such as cotton polyester, wool polyester, etc., which are widely used in various types of fabrics and decorative materials. Polyester fiber can be used industrially in conveyor belts, tents, canvas, cable, fishing nets, etc., especially as a polyester cord on tires, and has a performance and nylon.
Polyester fiber is used in various industries because of its outstanding advantages, playing its great role and excellent performance.
