The terylene is a synthetic fiber variety with the largest world output and the most extensive application, and accounts for more than 60 percent of the world synthetic fiber output. The fiber is widely used for textiles such as clothing materials, bedding articles, various decorative fabrics, national defense and military special fabrics and other industrial fiber products, such as filter materials, insulating materials, tire cords, conveyor belts and the like. With the continuous and rapid increase of domestic economy and the continuous improvement of domestic resident consumption capability, the demand of the polyester staple fiber in domestic areas is also continuously increased. The productivity of Chinese polyester series products is increasing at a surprising speed, and the productivity of polyester fibers is increasing rapidly, so that China is gradually developing into an important processing base of world polyester products.
Dacron has a wide range of applications and is used in a large number of articles of clothing and industry. The flame-retardant polyester has permanent flame retardance and wide application range, and plays a plurality of roles in the field of protective clothing besides playing a role of no substitution in industrial textiles, building interior decoration, vehicle interior decoration and the like. According to the national standard of flame-retardant protective clothing, the fire-retardant protective clothing is used by the departments of metallurgy, forestry, chemical industry, petroleum, fire fighting and the like. The number of people who should use the flame-retardant protective clothing in China is more than million, and the market potential of the flame-retardant protective clothing is huge. Besides pure flame-retardant polyester, the polyester can be used for producing multifunctional series products with flame retardance, water resistance, oil repellency, static resistance and the like according to special requirements of users. If the flame-retardant polyester fabric is subjected to waterproof and oil-repellent finishing, the functionality of the flame-retardant garment can be improved; interweaving flame-retardant polyester and conductive fibers to produce an antistatic flame-retardant fabric; the flame-retardant fiber and the high-performance fiber are blended and interwoven to produce the high-performance flame-retardant fabric; the flame-retardant fiber is blended with the fibers such as cotton, viscose and the like, so that the comfort of the protective clothing is improved, and secondary burns are reduced.
