▎ 摘　　要

NOVELTY - Cool sensory master batch comprises a substrate, and a graphene material and a jade powder dispersed in the substrate, the substrate comprises at least two of polyester material, nylon material, and polypropylene material, the graphene material includes at least two of graphene, graphene oxide, and graphene derivative. USE - The cool sensory master batch and cooling sensation fiber is useful in yarns, fabrics, garments, and nonwoven fabrics (claimed). ADVANTAGE - The cool sensory master batch: improves feeling of cool feeling; reduces addition amount of jade powder under the same cooling feeling requirement; improves problem of poor fiber comfort, powder drop and odor caused by excessive addition of jade powder; obtains functional particles by first mixing the graphene material and the jade powder with the fiber substrate, and then mixing the two with the blank fiber substrate, which solves agglomeration problem of graphene material and jade powder, and improves its dispersibility, and make the distribution of coolness more uniformly.
