Flame retardant clothing commonly used fiber and its characteristics
Flame retardant overalls is what we usually say welding protective clothing. Flame-retardant overalls are divided into permanent flame-retardant overalls and durable flame-retardant overalls, permanent flame-retardant overalls means that the yarn or silk is already flame-retardant and has high resistance to washing. The relative post-processing flame retardant overalls means that the fabric is essentially not flame retardant properties, the yarn or silk woven fabric after the post-processing, post-treatment of flame-retardant fabrics is relatively poor washing resistance performance. What fabric permanent flame retardant clothing?
Flame retardant clothing commonly used fiber and its characteristics:
(1) Nomex fiber: heat-resistant flame-retardant fiber (scientific name: meta-aramid fiber, aramid fiber 1313); Nomex fiber Features:
1, heat-resistant permanent flame-retardant fiber, with high strength, high wear resistance, low shrinkage, chemical stability, acid and alkali resistance and organic chemicals, corrosion and other characteristics;
2, good dimensional stability, long-term use at 250 ℃ heat shrinkage of only 1%, in case of fire does not melt, no droplets, does not produce toxic gases;
3, more than 400 ℃ began to decompose, the decomposition of the fabric thickening, in the 900 ℃ -1500 ℃ temperature can be insulated without heat transfer without cracking. Flame-retardant workwear made of Nomex® fiber is light, elastic, breathable, soft and comfortable to wear;
4, due to the outstanding performance of the fabric from the fiber itself, rather than printing and dyeing auxiliaries, it can be arbitrarily washed, its function unchanged;
5, Kevlar® fiber added to the bullet-resistant fiber to increase the fabric's rupture strength and tear strength. The addition of nylon with a carbon fiber core to the fabric provides a permanent anti-static function to the fabric;
6, Nomex ® oil and water repellent finishing so that the cloth has the advantages of oil repellent and easy to decontamination.
(2) Kevlar® fiber: High-density low-stretch bullet-proof fiber (scientific name: para-aramid fiber, domestic aramid 1414 fiber); Kevlar® fiber Features:
1, Kevlar has very good thermal stability, fire resistance, chemical resistance, insulation, and high strength and modulus, Kevlar physical properties compared with other fibers, Kevlar fibers are asbestos 2 to 11 times the strength of 1.6 times the intensity of high-strength graphite, glass fiber is 3 times the strength of the same weight of steel fibers 5 times the intensity. Kevlar's density is very low, almost half asbestos density;
2, thermal stability, Kevlar large heat test (TGA) is very stable, until 600 ℃ significant weight loss;
3, low erosion, with high content of Kevlar test piece, showing less aggressive than the semi-metal sheet;
4, wear resistance, compared with the brake pads made of asbestos fibers, Kevlar fiber opening in a good state, showing a very low wear.
Therefore, the flame-retardant overalls manufactured by the above fabrics are widely used in petroleum, petrochemical, chemical and power industries, and are especially favored by labor protection departments of foreign-funded enterprises.
