▎ 摘　　要

NOVELTY - Preparing graphene thermal fabric, comprises (i) obtaining graphene oxide powder and dissolving it in deionized water to obtain a graphene oxide solution; (ii) obtaining polyvinyl alcohol and adding in graphene oxide solution, heat to 70-80℃, fully stirring to make polyvinyl alcohol swell in graphene oxide solution and obtaining polyvinyl alcohol-graphene oxide solution; (iii) cooling polyvinyl alcohol-graphene oxide solution to room temperature, get glycerol and polyethylene glycol and dissolving in polyvinyl alcohol-graphene oxide solution, fully stirring and making spinning solution; (iii) spinning spinning solution on the viscose fiber by an electrospinning device to obtain a graphene composite fiber,where the graphene composite fiber is spun into yarn A, and the airgel fiber is spun into yarn B, and yarn A and yarn B are blended to make a fabric; and (v) dying and shaping fabric to obtain a graphene thermal fabric. USE - The method is useful for preparing graphene thermal fabric. ADVANTAGE - The method enables to prepare insulating material for graphene, which is light, skin-friendly, and has good warm-keeping effect. The graphene oxide is made as the fiber material, for weaving warm keeping fabric, making the graphene the thermal underwear has the function of diminishing inflammation and inhibiting bacteria. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene thermal underwear, obtained by cutting and sewing the graphene thermal fabric prepared of the graphene thermal fabric.
