Abstract

The invention relates to the technical field of preparation of polymer materials, and in particular relates to a preparation method of an antibacterial self-cleaning fabric. A silver crystal seed solution is prepared from a silver nitrate solution, a trisodium citrate aqueous solution and a sodium borohydride solution, polyvinylpyrrolidone, L-ascorbic acid and the like are added into the silver crystal seed solution, an activated reducing solution is prepared by diluting, a pure cotton fabric is cut and treated as a base fabric to obtain a modified cotton fabric, ethyl orthosilicate and absolute ethanol are mixed, diluted hydrochloric acid is added to obtain a silica sol, absolute ethanol, 5,5-dimethylhydantoin and methacryloyl chloride are mixed and ultrasonically dispersed to obtain an antibacterial monomer suspension, the antibacterial monomer suspension is added to ethyl titanate to obtain a mixed solution, and acetic acid and the silica sol are added dropwise to the mixed solution, ichloromethane is used to dilute to obtain an antibacterial spraying agent, and the antibacterial spraying agent is sprayed by an atomizer to the surface of the modified cotton fabric to obtain theantibacterial self-cleaning fabric, and the application prospect is broad.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a method for preparing an antibacterial self-cleaning fabric. Background technique [0002] As an essential element of human life, clothing often needs to be washed for reasons of cleanliness. Frequent washing is prone to pilling or deformation, which affects both appearance and comfort. At the same time, clothing cleaning will cause huge waste of water resources and energy. waste, and chemical detergents also pollute the environment. [0003] Self-cleaning fabric refers to the special performance of surface super-hydrophobic or photocatalytic degradation of pollutants through post-processing and finishing, so as to reduce the number of washings of clothes or realize no-cleaning of clothes, reduce the use of detergent, and finally achieve energy saving and energy saving. Water and environment friendly purpose. Self-cleaning fabrics can be divided into surfa...
