Ultra-high molecular weight polyethylene fiber (high-strength polyethylene fiber), aramid fiber and carbon fiber are considered as the three major high-performance fibers. Among them, the ultra-high molecular weight polyethylene fiber has high strength, high modulus, light weight, softness, ultraviolet resistance, impact resistance, acid and alkali resistance, seawater corrosion resistance, etc. It has been widely applied in safety protection, aviation, aerospace, navigation, weapons, shipbuilding, building materials, sports, medical and many other fields, such as body armor, stab-resistant clothing, shields, armored protective barriers for tanks and ships, parachute cables, marine engineering ropes, climbing ropes, deep-sea cages, fishing nets, fishing lines, rowing, sailing, shock-resistant containers, etc., and new applications are constantly being developed.
