Permanently flame retardant work clothesThe fabric used is yarn or silk that has flame retardant properties and is resistant to High washability. The relative post-processingFlame-retardant work clothes means that the clothing fabric does not have flame-retardant properties in nature. The yarn or silk is woven into the fabric and then post-processed. The post-processingFlame-retardant FabricRelatively speaking, the washing resistance is slightly poor. So what are the fabrics of permanent aramid flame retardant clothing? Now let’s introduce the commonly used fibers and their characteristics for flame retardant clothing:
(1)Aramid1313
Aramid 1313 fiber characteristics:
1. Heat resistance Permanently flame-retardant fiber has the characteristics of high strength, high wear resistance, low shrinkage, stable chemical structure, and resistance to corrosion by acids, alkalis and organic chemicals;
2. Good dimensional stability, The thermal shrinkage rate is only 1% after long-term use at 250°C. It will not melt when exposed to fire, has no droplets, and does not produce toxic gases;
3. It does not start to decompose until it exceeds 400°C, and the cloth surface becomes thicker during decomposition. It can insulate heat transfer without cracking at temperatures of 900℃-1500℃. Flame-retardant work clothes made of aramid 1313 fiber are light, elastic, breathable, soft and comfortable to wear;
4. Because the outstanding performance of the cloth comes from the fiber itself, not the printing and dyeing auxiliary agent, so it can be washed at will and its function remains unchanged;
5. Aramid 1313 has been treated with oil and water repellent finishing, so that the cloth has the advantages of oil and water repellency and easy decontamination.
(2)Aramid1414
Aramid Characteristics of aramid 1414 fiber:
1. Aramid 1414 has very good thermal stability, fire resistance, chemical resistance, insulation, high strength and modulus. It combines the physical properties of aramid 1414 with For comparison with other fibers, aramid 1414 fiber is 2 to 11 times stronger than asbestos, 1.6 times stronger than high-strength graphite, 3 times stronger than glass fiber, and 5 times stronger than steel fiber under the same weight. And the density of aramid 1414 is very low, almost only half of the density of asbestos;
2. Thermal stability, aramid 1414 is very stable in the thermal test (TGA), and does not have significant weight until 600°C Loss;
3. Low corrosiveness, aramid 1414 test piece with high content, showing lower corrosiveness than semi-metallic piece;
4. Wear resistance, with Compared with brake pads made of asbestos fiber, when the aramid 1414 fiber is well opened, it shows very low wear.
(3)AramidIIIA fiber
Aramid IIIA fiber is made of 93% aramid Made of 1313 fiber, 5% aramid 1414 fiber and 2% nylon with a carbon fiber core. The fiber is added with aramid 1414 ballistic fiber to increase the breaking strength and tear resistance of the cloth. Nylon with a carbon fiber core is added to the fiber to make the cloth permanently anti-static.
Flame-retardant work clothes made of the above fabrics are widely used in petroleum, petrochemical, chemical, electric power and other industries, and are especially favored by the labor protection departments of foreign-funded enterprises.
The permanent flame retardant work clothes produced by City Textile mostly use aramid IIIA retardant Made of burning fabric.
