Characteristics And Composition Analysis Of Polyester Yarn


    Polyester yarn refers to the production of cotton yarn used in polyester, polyester is a kind of polymer spinning made of fiber, at present, more than two phthalate as raw materials for the production of fiber, according to its raw materials, the English name "Polyethylene Terephthalate" abbreviation, "Pet" fiber. In China is commonly known as polyester. The so-called "yarn", in fact, refers to "yarn" and "line" of the general term, in the study of clothing materials defined as follows: Yarn "is a large number of short fibers or filaments arranged in an approximate parallel state, and along the axis of rotation twisting, composed of a certain strength and linear density of the slender objects, and" line "is composed of two or more than two strands of single yarn twisted together into the strand.Polyester Yarn
     Fiber has two main characteristics: one is fine to people can not be directly observed with the naked eye, the diameter is generally between a few microns to dozens of microns or more thin; the second is that its length-diameter ratio is in a few Baisi to tens of thousands of or even theoretically infinite, it is related to the type of fiber, which makes the fibers exhibit long properties in mechanics, such as the small-area deformation when bending and twisting, and the overall tensile deformation even within the elastic range. Therefore, the fiber is a thin and long, that is, the diameter of the thin to the naked eye can not be directly observed, and its length and diameter of the ratio of more than dozens of times times.Polyester Yarn
     Artificial fiber is a textile fiber made by chemical processing, which contains natural fiber or protein fiber, such as wood, sugarcane, reed, soy protein fiber and other fiber materials that lose the value of textile processing. The man-made fibers mainly used in textile are: viscose, acetate fiber, copper ammonia fiber. Regenerated fibers are fibers made from natural polymers, such as regenerated cellulose fibers, regenerated protein fibers, regenerated starch fibers, and regenerated synthetic fibres. The chemical composition of synthetic fibres is completely different from that of natural fibres, from some substances which do not contain cellulose or protein, such as petroleum, coal, natural gas, limestone or agricultural and sideline products, to synthesize units first, and then made into fibers by chemical synthesis and mechanical processing. such as polyester fiber (polyester), polyamide fiber (nylon or nylon), polyvinyl alcohol fiber (Vinylon), Polyacrylonitrile fiber (acrylic), polypropylene fiber (polypropylene), PVC fiber (copolymer) and so on. Inorganic fibers are made from natural inorganic materials or carbon-containing polymers by manual or direct carbonization. Including fiberglass, metal fiber and carbon fiber.Polyester Yarn
