Silk fabric was sputter-treated with Au, Cu, SUS, and Ti using poly(vinyl alcohol) (PVA) as a binder, and its changes in color, antielectrostatic property, airpermearbility, and rubbing fastness were investigated. Sputter-treated silk fabric had a natural color of metal target, which was deepened by treatment of PVA solution. The rubbing fastness of thin metal layer formed by sputtering was improved by PVA treatment. Au had highest rubbing fastness among the metal targets. In addition, PVA treatment posterior to sputtering resulted In higher rubbing fastness than the other treatment method. However, a reverse trend was found in antielectrostatic property. Air permeability of the sputter-treated silk fabric was improved by PVA treatment, which was highest when sputtering was conducted prior to PVA treatment.
