Polyester (a) Overview of the scientific name of polyester Polyethylene terephthalate fiber overalls, referred to as polyester fibers. Polyester in industrial production began in 1953, due to its good performance, versatile, so send people quickly has become one of the world's largest chemical fiber production. Polyester staple fiber in the main, it is mainly used for cotton, wool viscose, linen and synthetic blends his total manufacturing all kinds of clothing textiles. But in recent years, the people of polyester hair longer than the fast, which is mainly processed into a variety of textured yarn, such as DTY, polyester filament networks such as wind, for weaving woven and knitted outerwear and underwear do. Also, polyester filament in the industry for the manufacture of tire cord, electrical insulating materials, strong rope and so on. In order to overcome the low moisture absorption polyester dyeing and poor will lack, by living modified Lun, recalling produce high hygroscopic polyester fiber, from polyester, cationic dyeable polyester and other properties. (B) the main physical and chemical properties of a polyester, form 2, 3 strong stretch and elasticity, moisture absorption and dyeing 4, other properties of polypropylene (a) Overview of polypropylene fiber polypropylene is the trade name, which is made from propylene polymerization raw materials. The resulting melt-spun fibers. Polypropylene industrial production started in 1957, is a rising star in the synthetic fiber. Because polypropylene has simple production process, products cheap, high strength, relative density of light, etc., so the development of faster polypropylene. Sinopec currently unified overalls, is the fourth largest polypropylene synthetic varieties. Polypropylene production, including staple fibers. Filaments and split film fibers. PP split film fibers are made of polypropylene film first labor clothes factory in the North Sea, and then the film is stretched, so that it is split into fibrils form the mesh and prepared. Polypropylene is used extensively for the manufacture of industrial fabrics such as nonwovens. Such as carpet. Industrial fabric. Rope. Nets. Building reinforcement. Carpet and upholstery etc. suction. In civilian clothes manufacturing company e-mail, or polypropylene can be pure spun wool, cotton or viscose and other blended to produce a variety of fabrics. Further, polypropylene split fibers can be used as packaging material.
