▎ 摘　　要

NOVELTY - Preparing antibacterial agent containing graphene and quaternary ammonium salt textile, comprises polymerizing 0.2-1 wt.% active graphene, 25-35 wt.% dimethyldiallylammonium chloride, 1-3 wt.% carboxy acrylic monomer and 0.5-1 wt.% allyl glycidyl ether, initiating by 3-6 wt.% initiator in solvent water and deionized water (balance amount) to obtain composite antibacterial finishing agent, where active graphene is active graphene modified by silane coupling agent containing double bond. USE - The method is useful for preparing antibacterial agent containing graphene and quaternary ammonium salt textile. ADVANTAGE - The composite antibacterial finishing agent has synergistic effect, excellent antibacterial properties; and is capable of interacting with cotton fibers so as to achieve lasting antibacterial effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for antibacterial agent containing graphene and quaternary ammonium salt textile obtained by above method.
