Method of preparing wear and cut resistant UHMWPE fibers

A method of preparing wear and cut resistant UHMWPE fibers, comprising steps of:

• preparing a mother liquor by adding 0.1-0.5 parts of coupling agent A, 1-20 parts of nano additive B, 1-20 parts of additive C, 0.1-5 parts of sodium stearate, 0.1-8 parts of nano-sized dispersant, and 0.1-10 parts of antioxidant into 1000 parts of solvent oil, and processed by a 1000-20000 r/min high-speed rotating emulsifier for 2-6 hours, and a mixing temperature being controlled at 25° C.-100° C., wherein the nano additive B is selected from the group consisting of SiO2, TiO2, Al2O3, MgO, CaO, Si3N4, ZrO2, CrO3, montmorillonite, nano carbon black, graphite, tin antimony oxide, and carbon nanotube, and wherein the additive C is selected from the group consisting of a basalt staple fiber, a rockwool staple fiber, a slag cotton staple fiber, a glass staple fiber, an aluminum silicate cotton staple fiber, a polyester staple fiber, a carbon staple fiber, and an aramid staple fiber;
• preparing a resin material which is an UHMWPE resin with a viscosity-average molecular weight of 2 millions-8 millions, adding 20-200 parts of the resin material into a ball grinder at a temperature controlled at 30° C.-100° C.;
• adding the mother liquor into the ball grinder at a speed of 2 parts/minute;
• blending and mixing the mother liquor and the resin material uniformly to form a mixed solution;
• vacuuming the mixed solution in a sealed container for 2-6 hours;
• and
• the mixed solution being extruded in sequence by a twin screw extruder, a metering pump, a spin beam, and processed by drafting, and drawing and winding formation.
