Pre-oxidized pan and para aramid blended fabric

Pre-oxidized (Panox, ox, preox) yarn and para-aramid blended fabric is woven from pre-oxidized polyacrylonitrile and para-aramid yarns spun by ring spinning.

Polyacrylonitrile pre-oxidized fiber is referred to as pre-oxidized fiber, which is obtained by high-temperature heat stabilization treatment using polypropylene nitrile fiber as raw material. The pre-oxidized yarn has high flame retardancy,The limiting oxygen index is greater than 40%. It has excellent thermal stability, the fiber does not melt, does not soften and shrink, and has no dissolved droplets during combustion. It is a quasi-non-combustible product.

The full name of para-aramid fiber is "poly-paraphenylene terephthalamide" (PPTA) fiber, which is an organic polymer fiber synthesized from terephthaloyl chloride and p-phenylenediamine. The No. 1 and No. 4 positions of the ring, also known as aramid 1414, Tapron, Kevlar, Twaron, have excellent properties such as high specific strength, high specific  modulus, high temperature resistance and flame retardancy, and carbon fiber, high-strength and high-modulus polyethylene and known as the world's three high-performance Energy fiber, the main outstanding advantages of para-aramid fiber are high strength and high modulus, its tensile strength is 6 times that of steel wire, tensile modulus is 2~3 times that of steel wire and glass fiber, high temperature resistance, at 560 ℃ No decomposition, no melting. acid and alkali resistance. Density (1.44g/cm2) is only one-fifth of steel wire,It has good flame retardancy and the limiting oxygen index is above 29.

The weaving process of pre-oxidized pan and  para-aramid blended fabrics mainly includes: winding, warping, sizing, drawing-in, weaving, and finishing. 

Pre-oxidized and para-aramid blended fabric has suitable textile processability , pre-oxygenated para-aramid blended fabric, the fabric is light, soft, good strength, good heat insulation effect, corrosion resistance, chemical environment resistance, radiation resistance and other advantages. The para-aramid blended fabric produced by Shanghai Sheng, aviation (aircraft seat fire barrier fabric/aircraft seat cover cloth/aviation blanket), petrochemical industry (fire insulation blanket for electric welding construction/reinforcing material for oil exploration cables), iron and steel smelting (furnace fitter clothing, cloth for gloves), Shipbuilding (fire blanket for electric welding construction) and other industries.

Pre-oxidized and para-aramid blended fabric application

Pre-oxidized  and para aramid blended fabrics can be made into flame-retardant and high-temperature resistant gloves, pre-oxidized  and para aramid blended fabrics can be used for special flame-retardant clothing, heat protective clothing, spark protection welding blanket firefighting clothing, steelmaking Clothes, fabrics for high-temperature work clothing, luggage and other outdoor products, It can also be used in industrial fabrics, flame retardant aviation products, high-speed train products, tunnel fire prevention, automobile hood insulation, fuel tank insulation, high-speed train products, camping tents and other heat insulation and flame retardant industries, with stable heat resistance and fire resistance. Can be customized production.  Pre-oxidized fiber and aramid blended  fabrics are also used in high-performance FR clothing, woven welding blankets, industrial fire protection layers, mechanical seals and gaskets, high-temperature belts.
