Abstract
A method for manufacturing an antibacterial copper nanofiber by injection molding includes the following steps: raw material mixing operation: mixing dry copper nanopowder having an averaged particle size of not more than 48 nm with a fiber raw material to form a mixed raw material; and injection molding operation, including plasticization, filling, pressurization, cooling, ejection, and product injection. Finally, an antibacterial copper nanofiber injection product is obtained. Or in the raw material mixing operation, after mixing a dry copper nanopowder having an averaged particle size of not more than 48 nm with a fiber raw material to form a mixed raw material, mixing and granulating operation can be added, including heating, blending, extruding and granulating the mixed raw material through a mixer, and then melting to form a plurality of antibacterial copper nano-masterbatches; and then injection molding operation is performed to obtain an antibacterial copper nanofiber injection product.
