Aramid fiber is mainly divided into two types, para-aramid fiber (PPTA) and meta-aramid fiber (PMIA). Since the 1960s, DuPont (DuPont) of the United States successfully developed aramid fiber and took the lead in industrialization. , In more than 30 years, aramid fiber has gone through the process of transition from military strategic materials to civilian materials, and the price has also been reduced by nearly half. Now aramid fiber is becoming more and more mature both in terms of research and development level and large-scale production. In the field of aramid fiber production, para-aramid fiber has the fastest development, and its production capacity is mainly concentrated in Japan, the United States, and Europe. DuPont announced last year that it will expand the production capacity of Kevlar fiber, and the expansion project is expected to be completed by the end of this year. Not to be outdone, well-known aramid companies such as Teijin and Hearst have expanded production or joined forces one after another, and actively explored the market, hoping to become a new force in this sunrise industry.

The full name of para-aramid is "poly-paraphenylene terephthalamide", which is Para-Aramid fiber in English. It is a new type of high-tech synthetic fiber with ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance. , light weight and other excellent properties, its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is only about 1/5 of steel wire. Under the high temperature, it will not decompose or melt. It has good insulation and anti-aging performance, and has a long life cycle. The discovery of aramid 1414 is considered to be a very important historical process in the material industry.


A German company has recently developed a high-performance ultra-fine para-aramid product, which is neither flammable nor molten, has high strength and great cutting ability, and is mainly used for the production of coated and uncoated fabrics and knitted products Various textile and clothing equipments such as needle felt and needle felt are resistant to high temperature and cut. The fineness of ultra-fine filament is only 60% of that of para-aramid fiber commonly used in occupational safety clothing. Using it to weave gloves can increase its cutting resistance by 10%. Using it to produce woven and knitted products has a softer feel and is easier to use. comfortable. Aramid cut-resistant gloves are mainly used in automobile manufacturing, glass industry and metal parts production plants. They can also produce leg protection products for the forest industry and provide anti-vandalism equipment for the public transportation industry. Utilizing the flame retardant and heat resistance of aramid fiber, it can provide protective suits and blankets and other equipment for fire brigades, as well as heat-resistant and fire-resistant clothing for casting, furnaces, glass factories and other high-temperature operating departments, as well as the production of aircraft seat fuel retardant. This high-performance fiber can also be used to create automotive tires, cooling hoses, V-belts and other components, optical fiber cables and protective equipment such as bulletproof vests, and can also replace asbestos as friction materials and sealing materials.

The global demand for aramid fiber shows a growing trend, and aramid fiber, as a new high-performance fiber, has entered a period of rapid development.
