Preparation method of nano silver-protein composite aqueous solution and protein-modified nano silver antibacterial textiles

The invention relates to a preparation method of nano silver-protein composite aqueous solution and protein-modified nano silver antibacterial textiles, and belongs to the nano technical field and the technical field of textile after-finishing. According to the technical scheme, the preparation method comprises the following steps: a first step of preparing a precursor of nano silver by using silver nitrate, preparing nano silver-protein composite liquor by using the protein as a stabilizer, and measuring the particle diameter of the nano silver as 10-50 nm; a second step of oxidizing cellulose textiles, carrying out functional modified finishing on the cellulose textiles by utilizing the nano silver-protein composite liquor to obtain the protein-modified nano silver antibacterial textiles. A preparation process of the nano sliver composite liquor is simple and convenient to operate, and a reducing agent and the stabilizer are nontoxic; a functional modifying process is adopted as one-bath process dip finishing. On one hand, the prepared textiles have excellent antibacterial performances, and on the other hand, the prepared textiles are coated and modified by protein, so that the multi-functionalization and wearability of the antibacterial textiles are improved.
