High performance high-temperature resistant aramid yarn
High performance materials are generally first applied in the military or industrial fields. With the maturity of technology and the advancement of processes, more and more high-performance materials are gradually entering ordinary households from these fields.

With the maturity of technology and the advancement of processes, more and more high-performance materials are gradually entering ordinary households from these fields. Aramid fiber, as a high-performance material born during the Cold War between the United States and the Soviet Union, was widely used in military and aerospace fields and gained widespread recognition. Nowadays, aramid fiber products of different specifications and models have been widely used in sports products, rail transit, and rubber composites.
1414 aramid fibers are mainly divided into para aramid and meta aramid. Para aramid, also known as PPTA or aramid 1414, is characterized by outstanding mechanical properties such as high strength, high modulus, strong tensile strength, and strong impact resistance. The strength of aramid 1414 is 5-6 times that of steel wire of the same thickness, but its density is only one-fifth that of steel wire. So aramid 1414 is an ideal bulletproof material, and bulletproof equipment made from it can consume the kinetic energy of bullets, thereby achieving the goal of protecting individual safety. At the same time, its lightweight advantage is widely used in the manufacturing of aircraft and rockets, reducing material load, lowering equipment quality, and saving usage costs.
1313 meta aramid, also known as PMIA fiber, is referred to as aramid 1313 in China. The main feature of aramid 1313 is its high temperature resistance. It can work for a long time at a high temperature of 220 ℃, with a 1% shrinkage after reaching 250 ℃, softening or melting at 300 ℃, and carbonization after reaching 400 ℃. This material will not burn in air and may even extinguish on its own. Due to its excellent flame retardant properties, aramid 1313 is also known as fire-resistant fiber. Aramid 1313 can be used as a high-temperature filtration material with good thermal stability and chemical resistance, and can be applied in complex fields such as chemical plants and thermal power plants. Due to its non combustible and self extinguishing properties when exposed to fire, it can also be made into special protective clothing to ensure the safety of personnel in the fields of welding, chemistry, and firefighting.
