Preparation method for copper bismuthate/silver silicate loaded cotton fabric on basis of plasma treatment

The invention discloses a preparation method for copper bismuthate/silver silicate loaded cotton fabric on the basis of plasma treatment. The preparation method comprises the following steps: plasma treatment of cotton fabric; and loading of the cotton fabric with copper bismuthate/silver silicate: immersing the cotton fabric into a copper bismuthate aqueous dispersion, carrying out light-shielded oscillation, adding a silver nitrate solution, carrying out light-shielded oscillation, dropwise adding a sodium metasilicate solution, carrying out light-shielded oscillation, taking out the cotton fabric, and carrying out drying. According to the invention, through plasma pretreatment of the cotton fabric, the surface of the cotton fabric is etched by plasma, so the deposition loading number of particles is increased; and through plasma treatment, cross-linking of cotton fiber with a photocatalyst can be increased at the same time, and the cotton fiber is prevented from losing, so the photocatalytic activity and s
