Abstract

Abstract Metal-coated fibrous objects comprising a fibrous base material, such as raw fibers, yarns, fabrics and final textile products; a synthetic resin base coat applied thereto; and a layer of metal deposited on said base coat by sputtering to a thickness in the range from 50 to 10,000 Å. The metal is selected from the group consisting of gold, silver, aluminum, tin zinc, nickel, copper, cobalt and chromium, or selected from the group consisting of Hastelloy X, Permalloy, stainless steels, titanium nitride and cobalt alloys. The sputtering is carried out in an atmosphere of an inert gas selected from argon, neon and xenon, under a pressure in the range from 3×10 -4 to 9×10 -2 Torr, and at an impressed voltage in the range from 200 to 1,000 volts.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 90 words
