What is polyester staple fiber, polyester staple fiber is polyester (polyethylene terephthalate, PET) polymerized by PTA and MEG and then spun into filaments after cutting the fiber. PET is rice-like and has a variety of varieties. 75% is used for polyester fiber for chemical fiber, and polyester staple fiber and polyester filament are manufactured according to the requirements of the textile industry.
The characteristics of polyester staple fiber
Strength: The strength of polyester fiber is nearly 1 times higher than that of 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 in synthetic fiber.
Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance is higher than other fibers. The fabric does not wrinkle and is good in keeping.
Abrasion Resistance: The abrasion resistance of polyester is second only to nylon, ranking second in synthetic fibers.
Water Absorption: Polyester has low moisture regain and good insulation properties, but due to low water absorption, the static electricity generated by friction is large and the dyeing performance is poor.
The uses of polyester staple fiber
The products are mainly used in the cotton spinning industry. They are individually spun or blended with cotton, viscose, hemp, wool, vinylon, etc. The resulting yarns are mainly used for apparel weaving, and can also be used for home-improvement fabrics, packaging fabrics, and fillings. Warm materials.
