▎ 摘  要

NOVELTY - Fabric comprises at 0.005-1 wt.% graphene, where the fabric has a combination of at least three features comprising antimicrobial, antistatic, anti-odor, wicking, thermal cooling and UV protection. USE - The fabric is useful: in a graphene coating solution (claimed); for manufacturing commercial products e.g. textile products in medical applications/hospitals e.g. aprons, garments, furniture covers, bed covers, pillow covers, curtains, other apparels, upholstery, carpets and bags. ADVANTAGE - The fabric: exhibits good/excellent rubbing fastness, a washing fastness, perspiration fastness, sublimation fastness and light fastness of 4-5; and water absorbency of 0.1-5 Sec; has antimicrobial, antistatic, anti-odor, wicking, thermal cooling and UV protection features; provides high tenacity and durability; and is economical, repeatable and commercially/industrially viable process for production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing (m1) a fabric comprising 0.005-1 wt.% graphene, where the fabric has a combination of at least three features comprising antimicrobial, antistatic, anti-odor, wicking, thermal cooling and UV protection, comprising contacting graphene with a fabric; (2) use of graphene for preparing a fabric comprising graphene; (3) a graphene coating solution comprising graphene and at least two agents comprising wetting agent, dispersing agent, lubricating agent, defoaming agent, pH control agent and/or fabric coating agent; and (4) preparing (m2) the graphene coating solution comprising (ia) dispersing graphene in a solvent and optionally a surfactant followed by mixing to prepare a graphene slurry, and (iia) mixing the graphene slurry with at least two agents comprising wetting agent, dispersing agent, lubricating agent, defoaming agent, pH control agent and/or fabric coating agent.
