High Tenacity Polyester Filament Bonded Sewing Thread has soft hand feel, good flame retardant effect, obvious flame retardant effect, no open flame, and automatic extinguishing. It has been widely used in textiles, home textiles, curtains, carpets, seat cushions, webbing and other fields. High Tenacity Polyester Filament Bonded Sewing Thread is an ideal raw material for producing flame retardant fabrics and blankets. Various specifications and ratios can be customized according to customer requirements. High Tenacity Polyester Filament Bonded Sewing Thread is a special fabric that can delay flame burning. Mainly used to make protective clothing, special functional clothing, industrial fabrics, widely used in fire protection, clothing, petroleum, electric power, natural gas, metallurgy, machinery, mining, chemical, coal, shipping and other industries.

The physical and mechanical properties, appearance and post-processing properties of High Tenacity Polyester Filament Bonded Sewing Thread are similar to ordinary polyester. Only a few fibers are slightly lower in strength than ordinary polyester, but do not affect textile processing. Because the structure of the flame retardant fiber is loose and the dye molecules are easy to enter, the dyeing speed is faster than that of ordinary polyester, and it can be dyed with disperse dyes or cationic dyes. The main manufacturing methods are: (1) Copolymerization flame retardant modification, such as using tetrabromobisphenol A hydroxyethyl ether or P-containing compounds as comonomers, and transesterification with dimethyl terephthalate and ethylene glycol and polycondensation to obtain copolymers. It is obtained by melt spinning and stretching; (2) blending flame retardant modification, adding P-containing compound or halogen-antimony composite flame retardant to the spinning melt, and then melt spinning and stretching. ; Or use composite spinning components to add flame retardant in the core layer, and the skin layer is ordinary polyester. The fiber prepared by this method not only improves the flame retardancy and flame retardancy durability, but also reduces the influence on the fiber properties. Although the effect of blending flame retardant modification is not as good as that of copolymer type, the process is simple; (3) flame retardant finishing, using P or halogen-containing olefinic monomers to conduct surface polymerization or graft copolymerization on fibers or fabrics or use three Polynitrile ammonia treatment obtained. Mainly used for interior decoration such as curtains and bedding; fabrics for flight suits, tents, parachutes, ropes, aircraft covers, open warehouses, etc.; conveyor belts in oil refineries, mines and inflammable and explosive factories.

High Tenacity Polyester Filament Bonded Sewing Thread is made of polyester filament or staple fiber, which has high strength, good elasticity, wear resistance, low shrinkage and good chemical stability. However, the melting point is low, the high speed is easy to melt, the needle eye is blocked, and the thread is easy to break. Pay attention to the selection of the needle. Mainly used for denim, sportswear, leather products, wool and military uniforms, etc. It is the most widely used and popular sewing thread at present. High Tenacity Polyester Filament Bonded Sewing Thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: fiber, synthetic fiber sewing thread and mixed sewing thread. With the development of the polyester industry, more and more pure polyester fibers are used as raw materials for sewing threads. Sewing thread refers to the thread used for sewing textile materials, plastics, leather products and sewing books and periodicals. Sewing thread is characterized by sewability, durability and quality appearance. Sewing thread is roughly divided into three types: fiber type, chemical fiber type, and mixed type because of different materials.
