the invention provides a preparation process of antibacterial and deodorant socks, which adopts a mode of loading zinc oxide on nano-silver, so as to avoid the yellowing phenomenon of the nano-silver, adopts PVA to coat Ag/ZnO powder, so as to improve the dispersibility of the Ag/ZnO powder in PET polyester slices, utilizes the synergistic effect of the PVA to coat the Ag/ZnO powder, chitosan and graphene oxide to realize the antibacterial and deodorant effect of polyester fibers, improves the flammability and antistatic capability of the polyester fibers, and adopts a mesh breathable structure to weave sock surfaces and sock legs, so as to improve the breathability of the antibacterial and deodorant socks. The antibacterial rate of the escherichia coli reaches 98%, the odor reduction rate is more than 98%, the surface resistivity can reach B level, the dye uptake rate is more than 94%, and the air permeability is more than 140 mm/s. .

In light of the above-described embodiments of the present invention, it is clear that many modifications and variations can be made by the worker skilled in the art without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
