The oxidation prevention effect and properties of polyester fabrics prepared by electro less silver plating were examined. Electroless silver plating was performed under the optimum conditions reported in previous studies. The e1ectroless silver plated fabric (polyurethane resin with a surface coating) was used to prevent oxidation. The surface morphology, electromagnetic wave shielding effectiveness and washing durability were measured by SEM and RF impedance analysis. The physical properties of the polyester fabrics by e1ectroless silver plating were analyzed by examining the oxidation prevention effect, tensile strength, stiffness, air permeability, antimicrobial activity and thermal resistance.
