▎ 摘　　要

NOVELTY - Antibacterial graphene fabric coated without chemical additives comprises an antibacterial thermal insulation layer, a pure cotton cloth layer, an antistatic layer and graphene sutures, where the antibacterial thermal insulation layer, pure cotton cloth layer and antistatic layer are stacked successively, and the antibacterial thermal insulation layer, pure cotton cloth layer and antistatic layer are stitched and fixed by graphene sutures. USE - Antibacterial graphene fabric coated without chemical additives. ADVANTAGE - The fabric has antibacterial and antiviral functions, and avoids the disadvantages of conventional fabrics that need to be coated with chemical additives, and is safe and non-irritating to the skin of young children under the condition of fully realizing the function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the antibacterial graphene fabric, involving (a) esterifying biomass graphene powder, terephthalic acid and ethylene glycol at 200℃, (b) subjecting the reactant obtained by esterification to final polycondensation at 280℃ to make biomass graphene polyester fiber, (c) preparing the antibacterial thermal insulation layer made by blending biomass graphene polyester fiber, spandex and polyester filament, (d) reacting graphene oxide and nylon fiber by in-situ polymerization to make graphene-modified nylon fiber, (e) making the antistatic layer by weaving graphene modified nylon fiber, (f) adding the graphene dispersion liquid and thread-making particles of the yarn into a twin-screw extruder for miscibility to obtain a miscible product, and extruding to obtain a graphene yarn raw material, (g) drawing the graphene yarn raw material into graphene yarn by yarn drawing machine, mixing the graphene yarn and flax thread, and braiding to make graphene suture, and (h) sequentially stacking the antibacterial thermal insulation layer, pure cotton cloth layer and antistatic layer together, and fixing by graphene sutures.
