Abstract
A method of producing electrically conducting acrylic and acrylic-series fibers by treating the fibers in a treatment bath containing divalent copper ions, a reducing agent capable of reducing the divalent copper ions to monovalent copper ions and a sulfur-containing compound which provides sulfur which reacts with the monovalent copper ions to produce copper sulfide. The copper sulfide is adsorbed into the fiber and results in a fiber of superior conductivity and which posesses the touch and other physical characteristics of the starting fiber.
Claims6
A method of making an electrically conducting fiber comprising treating an acrylic fiber or modacrylic fiber in a bath containing divalent copper ions, a reducing agent capable of reducing said copper ions to monovalent copper ions and a sulfur-containing compound to convert said monovalent copper ions to copper sulfide wherein said fiber adsorbs copper sulfide.
