NOVELTY - A preparation of antistatic and anti-pilling cashmere graphene blended yarn, involves (1) mixing graphene composite fibers and cashmere fibers, laying layers for 2-3 times, adding wool agent, laying layers and beating again for 1-2 times, and carrying out fuzz treatment for 15-20 hours, forming a blended fiber, (2) carding the blended fibers into a single fiber state on the carding machine, and adding graphene conductive filaments to mix the sliver to obtain a sliver, (3) successively carrying out mixed strip combing, combing, re-combing, four needle combing and five needle combing operations, (4) after carrying out six needle combing, seven needle combing, eight needle combing and nine needle combing in turn, then carrying out roving processing, and (5) successively carrying out spinning, winding, rewinding, hot washing, dehydration drying, doubling and twisting processes to obtain antistatic and anti-pilling cashmere graphene blended yarns. USE - Preparation of antistatic and anti-pilling cashmere graphene blended yarn. ADVANTAGE - The method adopts graphene composite fiber to composite graphene and polyvinyl alcohol fiber, and the polyvinyl alcohol fiber has the effect of high strength, acid and alkali resistance, and its polyhydroxy strong polarity is well combined with graphene. The polyvinyl alcohol fiber has a larger specific surface area, which increases the interfacial adhesion between the fiber and the graphene, thereby improving the cohesion between the graphene composite fiber and the cashmere fiber. The method realizes that graphene and polyvinyl alcohol fibers are well dispersed in the polyvinyl alcohol resin to form a unique three-dimensional network structure. The agglomeration and uneven dispersion of graphene in the polyvinyl alcohol resin are avoided, and the bonding strength of the graphene composite fiber is improved. The graphene is uniformly dispersed in the formed three-dimensional network structure to form a conductive network, which can maintain the conductivity without decay even after long-term use and water washing, and has good durability. DETAILED DESCRIPTION - A preparation of antistatic and anti-pilling cashmere graphene blended yarn, involves (1) mixing graphene composite fibers and cashmere fibers, laying layers for 2-3 times, adding wool agent, laying layers and beating again for 1-2 times, and carrying out fuzz treatment for 15-20 hours, forming a blended fiber, (2) carding the blended fibers into a single fiber state on the carding machine, and adding graphene conductive filaments to mix the sliver to obtain a sliver, (3) successively carrying out mixed strip combing, combing, re-combing, four needle combing and five needle combing operations, (4) after carrying out six needle combing, seven needle combing, eight needle combing and nine needle combing in turn, then carrying out roving processing, and (5) successively carrying out spinning, winding, rewinding, hot washing, dehydration drying, doubling and twisting processes to obtain antistatic and anti-pilling cashmere graphene blended yarns. The amount of graphene mixed fibers added is 0.8-1.5% of the quality of the cashmere fibers. The amount of graphene conductive filament added is 1-1.5% of the total mass of the blended fiber.
