Polyester is an important variety in synthetic fiber. It is the commodity name of polyester fiber in China. It is mainly obtained from petroleum cracking, and can also be obtained from coal and natural gas. Polyester, commonly known as polyester. It belongs to synthetic fiber in chemical fiber. Synthetic fiber manufacturing is the largest and most branched sub-sector in the chemical fiber industry. In addition to polyester, its products include acrylic, nylon and spandex. In the end, the term "polystyrene" is used for the description of grey fabrics, fabrics and garments. Such as: polyester/cotton grey cloth called T/c cloth polyester for more precise chemical raw material terminology. Generally, polyester synthetic products are called chemical fiber grey fabrics or fabrics. 1) High strength, impact strength is 4 times higher than nylon and 20 times higher than viscose fiber. 2), good flexibility. The elasticity is close to that of wool, and when it is stretched by 5% to 6%, it can be almost completely recovered. The wrinkle resistance is superior to other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The elasticity is 2 to 3 times higher than that of nylon. 3) Good heat resistance. 4), good water absorption. 5) Good wear resistance. Wear resistance is second only to nylon with the best abrasion resistance, better than other natural and synthetic fibers. 6), good light resistance. Lightfastness is second only to acrylic. 7), corrosion resistance. It is resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can decompose it. 8), poor dyeability. Polyester industrial yarns can be classified into standard type (HT high-strength low-stretch series), low-shrink type (LS medium-low low-shrink series), and dimensionally stable type (HMLS high-mode low-shrink series) according to their performance. Standard polyester industrial yarns are widely used, demanding, and manufacturing difficulty and production cost are relatively low. Low-shrinkage and dimensionally stable polyester industrial yarns have high performance requirements, are difficult to manufacture, and have relatively high production costs. In particular, dimensionally stable polyester industrial yarns are mainly used for radial tires for passenger cars and light-duty vehicles. Safety, higher quality requirements. The cord fabric is the skeleton material of the tire casing, and its weight accounts for 10% to 15% of the total weight of the tire. The cost is about 37% of the tire production cost, and it is one of the main raw materials for tire production. At present, the tire cord fabric mainly includes nylon cord fabric, polyester cord fabric, viscose cord fabric and steel cord fabric. With the continuous improvement of the meridian rate of tires, the general trend is that the demand for polyester industrial yarns continues to increase, and the output of polyester industrial yarns continues to increase.
