▎ 摘　　要

NOVELTY - Blended yarn comprises cotton multifunctional fiber and graphene fiber blended. The blended yarn comprises (a) taking hemp fiber into pectinase solution at room temperature, taking processed hemp fiber into chitosan aqueous solution for leaching, dehydrating, drying, (b) taking the obtained hemp fiber and bamboo fiber, wool fiber and cotton fiber into acetone for leaching, carrying out ultrasonic vibration treatment, washing and drying, to obtain multifunction cotton fiber, (c) taking the obtained cotton fiber and graphite fiber, mixing uniformly, twisting into mixed yarn. USE - Used as blended yarn. ADVANTAGE - The blended yarn: is bacterial free. DETAILED DESCRIPTION - Blended yarn comprises cotton multifunctional fiber and graphene fiber blended. The blended yarn comprises (a) taking hemp fiber into pectinase solution at room temperature, taking processed hemp fiber into chitosan aqueous solution for leaching, dehydrating, drying, (b) taking the obtained hemp fiber and bamboo fiber, wool fiber and cotton fiber into acetone for leaching, carrying out ultrasonic vibration treatment, washing and drying, to obtain multifunction cotton fiber, (c) taking the obtained cotton fiber and graphite fiber, mixing uniformly, twisting into mixed yarn, where mass ratio of the cotton multifunctional fiber and graphene fiber is 100:1-10.
