Antibacterial textile dye

The invention discloses an antibacterial textile dye. The antibacterial textile dye is prepared from the following raw materials in parts by weight: 35-55 parts of branched-chain vinyl guanamine, 10-14 parts of a plant dye extract, 1-5 parts of nano-silver and/or nano titanium dioxide, 5-10 parts of a dispersing agent, 1-4 parts of a softener, 1-2 parts of a defoaming agent and 90-110 parts of deionized water. The antibacterial textile dye has the advantages that high-quality vinyl guanamine is adopted as a binder, so that the defects that the surface shows colloidal gloss, the pungent smell is heavy, a formed film is hard, and the like due to the fact that acrylic emulsion is used in a traditional textile dye can be overcome; the nano-silver and/or the nano titanium dioxide are adopted asan antibacterial agent, so that bacteria represented by escherichia coli and staphylococcus aureus can be effectively inhibited, and the inhibition rate reaches up to 90%; and a plant dye body is added, so that the dyeing fa
