Polyester staple fiber is an important kind of constituent fiber and the trade name of polyester fiber. It is a kind of fiber-forming polymer poly (ethylene terephthalate) (PET), which is prepared by esterification, transesterification and polycondensation with purified p-benzoic acid (PTA) or p-phenylester (DMT) and ethylene glycol (eg) as raw materials, and is made by spinning and post-treatment.
Chemical fiber is a kind of fiber with textile function, which is made of natural polymer compounds or artificial polymer compounds through the processes of preparation of spinning stock solution, spinning and post-treatment.
Chemical fiber fabric is a new type of clothing material developed in modern times. Here mainly refers to the pure, blended or interwoven fabric processed by chemical fiber, that is, the fabric woven by purified fiber, excluding the blended and interwoven fabric with natural fiber. The characteristics of chemical fiber fabric are determined by the characteristics of the chemical fiber itself.
Fiber can be divided into plant fiber: cotton and hemp
Chemical fiber is the general name of fibers made of natural or artificial polymer materials and processed by chemical or physical methods. Due to the different sources of polymer compounds used, they can be divided into man-made fibers with natural polymer materials as materials and constituent fibers with constituent polymer materials as materials. Chemical fiber for short. Polyester is an important kind of constituent fiber and the trade name of polyester fiber in China. It is a kind of fiber-forming polymer poly (ethylene terephthalate) (PET), which is prepared by esterification, transesterification and polycondensation with purified p-benzoic acid (PTA) or p-phenylester (DMT) and ethylene glycol (eg) as raw materials, and is made by spinning and post-treatment. Briefly speaking, it is a chemical fiber containing polyester, which belongs to the artificial polymer material in the chemical fiber.
