Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Because of its flame retardancy, flame retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, building interiors, and vehicle interior decoration, it also plays a lot of roles in the field of protective clothing. According to the national standards for flame retardant protective clothing, metallurgy, forestry, chemical, petroleum, fire protection and other departments should use flame retardant protective clothing. The number of people who should use flame retardant protective clothing in China is more than one million, and the market potential of flame retardant protective clothing is huge. In addition to pure flame-retardant polyester, we can produce flame-retardant, waterproof, oil-repellent, anti-static and other multi-functional series products according to the special requirements of users. For example, the waterproof and oil-repellent finishing of flame retardant polyester fabric can improve the functionality of flame retardant clothing; flame retardant polyester and conductive fibers are interwoven to produce antistatic flame retardant fabrics; flame retardant fibers and high-performance fibers are used for blending and interweaving , which can produce high-performance flame-retardant fabrics; flame-retardant fibers are blended with cotton, viscose and other fibers to improve the comfort of protective clothing and reduce secondary burns.
