What are the characteristics of recycled cotton polyester staple fiber?

  Recycled cotton polyester staple fiber is a staple fiber of several centimeters to more than ten centimeters.

  Strength: the strength of recycled cotton polyester staple fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so the polyester fabric is strong and durable.

  Heat resistance: it can be used at 70 ~ 1700c. It has good heat resistance and thermal stability in synthetic fibers.

  Elasticity: its elasticity is close to that of wool, and its wrinkle resistance is higher than that of other fibers. The fabric does not wrinkle and has good line retention.

  Wear resistance: its wear resistance is second only to nylon and ranks second among synthetic fibers.

  Water absorption: it has low water absorption and moisture regain and good insulation performance, but due to low water absorption, large static electricity generated by friction and poor dyeing performance.

  Recycled cotton polyester staple fiber is an important variety of synthetic fiber and the trade name of polyester fiber in China. It is a fiber-forming polymer polyethylene terephthalate (PET) prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation, which is made by spinning and post-treatment. As a garment fiber, polyester fabric can achieve the effect of wrinkle free and non ironing after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc. it is widely used in various clothing materials and decorative materials. In industry, polyester can be used for conveyor belt, tent, canvas, cable, fishing net, etc., especially polyester cord for tire, which is close to nylon in performance. Polyester can also be used as electrical insulation materials, acid resistant filter cloth, cloth for pharmaceutical industry, etc. Synthetic fiber has been widely used in various fields of national economy because of its high strength, wear resistance, acid resistance, alkali resistance, high temperature resistance, light weight, heat preservation, good electrical insulation and no mildew.
