Abstract

The invention relates to a crosslinked ultrahigh molecular weight polyethylene fiber and a wet preparation method thereof. The decreasing rate of the weight-average molecular weight of ultrahigh molecular weight polyethylene caused by radiation or irradiation splitting is less than 10%. The ultrahigh molecular weight polyethylene fiber disclosed by the invention has excellent heat resistance and creep resistance and high mechanical strength, and therefore, the ultrahigh molecular weight polyethylene fiber is especially suitable for preparing bulletproof vests, helmets, lightweight armors, sails, mooring ropes, fishing nets, optical cable reinforcement bodies, parachutes, filter materials, radomes, wind turbine blades and the like which are ultrahigh in mechanical strength and heat resistance.

Description

technical field [0001] The invention relates to polyethylene fiber and its preparation method, in particular to ultra-high molecular weight polyethylene fiber and its preparation method. Background technique [0002] UHMWPE fiber is the third-generation high-performance fiber after carbon fiber and aramid fiber. It has mechanical properties unmatched by other high-performance fibers.
