Abstract

The invention discloses a graphene antibacterial fabric. The fabric comprises, by weight, 80-140 parts of graphene composite fibers, 10-15 parts of bamboo charcoal fibers, 6-12 parts of PTT, 30-50 parts of cotton and 8-12 parts of an antibacterial agent, wherein the graphene composite fibers comprise 0.6-1.5 parts of graphene and 79.4-138.5 parts of a fiber matrix. A preparation method of the graphene composite fibers includes the following steps of S1, pretreatment; S2, dry mixing, S3, blending and granulating; S4, melt spinning; S5, drawing and shaping, and then the graphene composite fibersare obtained. A preparation method of the graphene antibacterial fabric comprises the following steps of S1, yarn blending, S2, mercerizing; S3, warping and weaving; S4, fabric weaving; S5, antibacterial finishing; S6, post-treatment including dyeing and finishing, washing, shaping and pre-shrinking. The graphene antibacterial fabric has the advantages of being comfortable, soft, breathable, cool, durable in antibacterial performance and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a graphene antibacterial fabric and a preparation method thereof. Background technique [0002] As one of the three elements of clothing, fabric is the material used to make clothing. It can not only interpret the style and characteristics of clothing, but also directly relates to the performance of clothing color and shape. With the gradual improvement of people's living standards, people have put forward more and more multifunctional and style requirements for fabrics, so conventional fabrics cannot meet the needs of the market. [0003] Functional fibers mainly include: modified fibers, such as modified fibers at the raw material stage to obtain anti-pilling, antistatic, hydrophilic, flame retardant, etc.; functional finishing generally includes: comfortable finishing, which is reflected in breathability, Finishing in terms of moisture permeability, lightness, smoot...
