▎ 摘　　要

NOVELTY - Graphene antibacterial heat preservation functional fabric comprises 40-70 wt.% hollow polyester fiber, 10-30 wt.% graphene fiber, 0.1-3 wt.% oil agent, and 0.1-3 wt.% finishing agent. USE - Graphene antibacterial heat-insulating functional fabric used in textile field (claimed). ADVANTAGE - The graphene antibacterial heat-insulating functional fabric has very good antibacterial effect and heat preservation, antibacterial rate reach more than 90% and has good service performance and wide application prospect, where surface material cost is low, has universality, and is easy to scale production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a preparation method of graphene antibacterial heat preservation function fabric, which involves: (a) using oil agent to hollow polyester fiber, graphene fiber; mixing, and loosening hollow polyester fiber, and graphene fiber short fiber after oiling; carding to obtain raw strip, then drawing to obtain cooked strip through two drawing strips; (b) spinning cooked strip; twisting to prepare blended yarn; weaving prepared blended yarn into knitted fabric, after finishing knitted fabric; (2) a knitted warm-keeping underwear, which comprises graphene antibacterial heat-insulating functional fabric; (3) a down jacket, which adopts graphene antibacterial heat preservation functional fabric.
