Abstract

The invention relates to a cotton fabric with different functions on two sides. One side of the fabric is an antibacterial finishing layer, and the other side of the fabric is an antifouling finishinglayer. The antibacterial finishing layer is made of polymethacryloyloxyethyl trimethyl ammonium chloride; and the antifouling finishing layer is made of polyethylene glycol-400 (PEG-400). The antibacterial finishing layer in the cotton fabric with different functions on the two sides is a non-skin contact layer and can effectively kill various bacteria and prevent bacterial adhesion, and the antifouling finishing layer is a skin contact layer and can prevent skin secretion adhesion, so that bacterial nutrition channels are cut off, and mildness and no irritation to the skin are guaranteed. The cotton fabric with the different functions on the two sides has efficient antibacterial capacity, excellent bacterial adhesion prevention capacity and excellent skin secretion pollution prevention capacity, is mild and non-irritant to the skin and has high safety.

Description

technical field [0001] The invention relates to a functional cotton fabric, in particular to a cotton fabric with antifouling and antibacterial functions on both sides. Background technique [0002] Cotton fabric has the characteristics of breathability, water absorption, and comfortable wearing, and is widely used in daily life. Some home textiles, underwear and other textiles will contact the skin, and secretions such as sweat and protein secreted by the skin will be adsorbed on the surface of cotton fabric fibers and become a source of nutrition for microorganisms. Locally rich nutrients and suitable temperature cause these microorganisms to multiply rapidly, forming bacterial plaques or biofilms on the surface of cotton fabrics, causing unpleasant odors, stains or discoloration, reducing the mechanical strength of the fabric and increasing the possibility of cross-contamination sex. Therefore, there is a need to develop a rapid, environmentally friendly, and cost-effec...
