▎ 摘  要

NOVELTY - A fabric comprises 0.0001-1 (weight/weight)% graphene in the form of a combination of single layer graphene and multilayer graphene, having a surface area of 300-800 m2/g. USE - Fabric e.g. natural fabric, synthetic fabric and/or blend of natural fabric and synthetic fabric, preferably cotton fabric or cotton polyester blend (all claimed). Uses include but are not limited to garment material, sportswear, apparel in hospital, medical device, air purifier and automotive textile application. ADVANTAGE - The fabric has desired antimicrobial effect including bactericidal effect, bacteriostatic effect and antiviral effect, antistatic effect, anti-odor effect, wicking effect, thermal cooling effect and/or ultraviolet protection effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of the fabric, which involves (i) dispersing graphene in a solvent and optionally a surfactant and mixing to obtain a graphene slurry, (ii) mixing the graphene slurry with a dyeing solution comprising a disperse dye, a reactive dye, a migration inhibitor, a wetting agent, dispersing agent, sodium bicarbonate and urea to obtain a coating composition, and (iii) coating a fabric with the coating composition to obtain graphene-containing fabric; the coating composition, which comprises 0.0001-7 (weight/weight)% graphene, solvent, 0.001-1 (weight/weight)% surfactant, 0.1-10 (weight/weight)% disperse dye, 0.1-10 (weight/weight)% reactive dye, 0.1-2 (weight/weight)% migration inhibitor, 0.1-5 (weight/weight)% wetting agent, 0.5-5 (weight/weight)% dispersing agent, sodium bicarbonate, and urea; and a kit for preparing the graphene-containing fabric, which comprises the graphene slurry and the dyeing solution.
