Process for producing an electromagnetic radiation-shielding, metallized polyester fiber textile material

摘要

An improved process for producing an electromagnetic radiation-shielding, metallized polyester fiber textile material comprising the steps of: pre-treating a textile material containing at least 15% by weight of polyester fibers with an aqueous solution of a caustic alkali to an extent that the weight of the polyester fibers is decreased from 10% to 35% based on the original weight of the polyester fibers; activation-treating the pre-treated textile material with a tin (II)-containing compound and with a palladium-containing compounds; and nonelectrolytically plating the activation-treated textile material in a plating mixture containing a compound of an electroconductive metal selected from the group consisting of nickel, copper, cobalt, chromium, and alloys of at least two of the above-mentioned metals to form a metal coating thereon.
