Extinguishers annual inspection high temperature resistant fibrous material refers to the continuous use under the conditions of a high temperature of above 200 ℃ does not decompose, and the main physical properties of the fiber material does not decrease. The high temperature resistant fibers into the inorganic fibers and organic fibers. The heat resistance of most of the inorganic fibers are in the 200 ℃ above, such as glass fibers, asbestos fibers and the like, but such fibers for various reasons, and now has been rarely used for fire fighter apparel. Heat resistant organic fibers into inherent flame retardant fiber flame retardant fiber and chemical modification. The intrinsically flame-retardant fibers generally contain aromatic or the stepped heterocyclic chain structure. Between bit aromatic polyethylene Thalidomide fiber, the annual inspection of fire extinguishers, also known as Kevlar 1313, its overall performance, including flame-retardant performance, high temperature resistance, spinnability, dyeing, performance, anti-aging properties as well as a variety of physical and mechanical properties are satisfactory, therefore, is one of the world's most widely used synthetic high temperature fiber.
Market, as part of the Fire Fighter Apparel fabrics. However, due to the Kermel fiber staining problem has never been satisfactorily resolved, limiting its application in the field of labor protection.
Polybenzimidazole (PBI) fiber microphone wow, is an excellent high temperature and resistance to the chemical reagents corrosion fiber, has a special series of excellent properties, such as good textile processing, outstanding flame retardant performance, high hygroscopic (moisture rate of up to 13% to 15%), good dyeing properties, excellent thermal stability and excellent chemical stability, an ideal material for the production of flame-retardant heat-resistant Fire Fighter Apparel. Fiber lightfastness somewhat less plus the price is more expensive, limiting its popularization and application.
