Durable antibacterial composite fabric based on graphene and preparation method thereof

Abstract

The invention discloses a lasting antibacterial composite fabric based on graphene. The lasting antibacterial composite fabric comprises a skin-friendly layer, a sweat absorption layer, an antibacterial layer and an anti-ultraviolet layer, water-soluble phenolic resin is used for carrying out modification treatment on bamboo fibers, so that the modified bamboo fibers have high specific surface area, and the adsorbability, the antibacterial property, the deodorization property and the ultraviolet resistance of the bamboo fibers are greatly improved; graphene oxide quantum dots are used as a matrix for fixing cerium oxide nano-particles, so that the cerium oxide nano-particles are uniformly distributed on the graphene oxide quantum dot nano-sheets, and the effects of slowly releasing the cerium oxide nano-particles and resisting bacteria for a long time are achieved by adding chitosan and glycerol; and nano zinc oxide and flower-like titanium dioxide are organically combined in the anti-ultraviolet layer, so that UVA and UVB in sunlight ultraviolet rays can be effectively shielded, and the self-cleaning property and the pollution resistance of the fabric are improved.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a graphene-based durable antibacterial composite fabric and a preparation method thereof. Background technique [0002] The raw materials of conventional fabrics are mainly cotton, hemp, silk, polyester, nylon, etc. The textile fiber fabrics with porous structure are easy to absorb bacteria during use, and the sweat and sebum excreted by the human body provide abundant resources for the reproduction of fungi. The nutrition of textiles will cause the growth of bacteria. The growth of bacteria not only produces odor, but also easily causes cross-infection and spreads diseases. It is also easy to damage fibers. With the improvement of living standards, people pay more and more attention to the comfort and functionality of textiles. Traditional fabrics It can no longer meet people's usage requirements. [0003] Graphene oxide can destroy the cell membrane of bact...

AI Technical Summary

Problems solved by technology

[0002] The raw materials of conventional fabrics are mainly cotton, hemp, silk, polyester, nylon, etc. Textile fiber fabrics with a porous structure are easy to absorb bacteria during use, and the sweat discharged from the human body and the shed sebum provide a rich environment for the reproduction of fungi. The nutrition of bacteria can cause the growth of bacteria. The growth of bacteria not only produces peculiar smell, but also easily causes cross infection and spreads diseases. It is also easy to damage fibers. With the improvement of living standards, people pay more and more attention to the comfort and functionality of textiles. Traditional fabrics Can no longer meet people's use requirements

[0003] Graphene oxide can destroy the cell membrane of bacteria, thereby causing the outflow of intracellular substances and killing bacteria, while most of the existing graphene antibacterial fabrics are prepared by directly setting a bonding coating on the fabric, and directly setting the coating on the fabric will cause The air permeability of the fabric is greatly reduced, and the washability is poor, so it cannot exert a lasting antibacterial effect
