Aramid fiber textile knowledge
2013-10-31 by bridge
aramid fabrics called the "poly-p-phenylenediamine terephthalamide, English as aramide fiber is a new type of high-tech synthetic fiber with ultra high strength, high modulus and high temperature, acid and alkali resistant, light weight other excellent properties, the strength of the wire 5 to 6 times, the modulus of steel wire or glass fibers, 2 to 3 times, the toughness is 2 times the wire, while the weight of only about 1/5 of the wire, at a temperature of 560 degrees Next, does not decompose and does not melt. It has good insulation and anti-aging properties, and has a long life cycle. The aramid found materials sector is a very important historical process.
Aramid fiber is an important defense and military material, order to adapt to the needs of modern warfare, the body armor of the United States, Britain and other developed countries are Kevlar material, Kevlar body armor, helmets, lightweight, effectively improve the army's fast response capability and lethality. During the Gulf War, the United States, France aircraft extensive use of Kevlar composites. In addition to military applications, is now available as a high-tech fiber material is widely used in the aerospace aviation, machinery and electronics, construction, automotive, sporting goods and other national economy in all aspects. In aviation, aerospace, aramid, due to the high quality of light and strength to save a lot of power fuel every lighten the weight of 1 kg spacecraft launch process, information, means to reduce the cost of $ 1 million . In addition, the rapid development of science and technology is open to the Kevlar, with more new civilian space. It is reported that, aramid products used in bullet-proof vests, helmets, etc., about 7 to 8%, aerospace materials, sports materials account for about 40%; the tire reinforcement belt material accounts for about 20%, There are high-strength ropes, etc. account for about 13%.
Kevlar is divided into two kinds of aramid fiber (PPTA) and aramid fiber (PMIA), 30 years time, aramid fibers have gone through the course of the transition to civilian goods by the military strategic materials prices also reduced by nearly half. Foreign Kevlar whether it is the level of R & D or large-scale production matures. Fastest in the field of aramid fire socks production, the development of aramid fiber capacity mainly in Japan and the United States, Europe.
The recent development of high-performance ultra-fine-aramid (Twaron), both non-flammable and will not melt, high strength and great the Hang cutting capacity, mainly used in the production of coated and non-coated fabrics, knitted variety of textile and apparel products and acupuncture felt both high temperature, cut-resistant equipment. Twaron ultrafine filament fineness of only occupational safety clothing commonly use 60% aramid, weaving gloves · Increases anti-cutting l0%, with its production of woven fabrics and knitted products, its softer feel, use it. more comfortable. Twaron cut resistant gloves mainly for the automotive industry, the glass industry and metal parts production factory production, but also for the forest industry the leggings supplies and equipment for the public transport industry to provide the vandal. Twaron flame retardant heat resistance, providing protective suits and felt rugs and other equipment for the fire department, as well as casting, kiln, glass and other high temperature operations departments to provide a heat-resistant fire suits, as well as the production of the aircraft seat fire retardant coated materials. Car tires, cooling hoses, V-belts and other parts can create with this high-performance fiber, optical fiber cable, and bullet-proof vests and other protective equipment, to do can replace asbestos friction materials and sealing materials.
