NOVELTY - Producing graphene composite fiber and cashmere fiber blended yarn involves selecting 40-50 wt.% graphene composite fibers and 50-60 wt.% cashmere fibers to form a blended fiber. The ratio of the fineness of the graphene composite fibers to the average fineness of the cashmere fibers is between 90% and 120%, and the ratio of the length of quantum energy fibers to the average length of cashmere fibers is between 95% and 105%. The graphene composite fibers and cashmere fibers are mixed, layered and crushed twice, then the woolen agent is added and crushed again, and then the cashmere fibers are bagged for more than 12 hours, finally adding graphene composite fiber layer and crushed for 2 times to get blended fiber. The blended fiber is subjected to carding using carding machine, where the carding interval of the carding machine during carding is the same as that of the production of cashmere products. USE - Method for producing graphene composite fiber and cashmere fiber blended yarn. ADVANTAGE - The method enables to produce graphene composite fiber and cashmere fiber blended yarn, which has tensile strength, excellent toughness, and under certain degree is washed by water. DETAILED DESCRIPTION - The speed ratio between the cylinder and the work roll is between 320/2.5 and 180/2.5, and the speed ratio between the cylinder and the doffer is between 360/20 and 300/15, feeding amount is 200-300g, tfeeding period is 30-40%, and the delivery speed is between 12-20m/minutes. The blended fiber after carding is subjected to spun yarn treatment, where the spinning count is 20Nm, draft multiple during spinning is between 1.28-1.32, spinning count is 25.5Nm-25.8Nm, and single yarn twist is between 580-620 T/M, twist direction is Z, and the spindle speed is between 6500-7000 revolutions/minute (rpm) to obtain single fiber blended yarn. 100% Cashmere fiber is selected, and the twist is prepared by the process of dyeing wool tops, blending, recombing, mixed tops, first needle combs, two needle combs, three needle combs, four needle combs, and rovings are twisted in Z direction between 30-90 T/M. 30-40 wt.% blended fiber single yarns and 60-70 wt.% cashmere single yarns are selected, where cashmere single yarns are used as decorative threads, and blended fiber single yarns used as core threads and fixed threads are used to make Yarn count of 12-15Nm having hollow spindle twist of 500-700 T/M, twist direction Z, outer twist twist 300-350 T/M in twist direction S, draft multiple is 15-22 times, and wool yarn with a core tension of 1.2-1.7%.
