Abstract
Electrically conducting fibers are prepared by introducing cyanic groups into a synthetic or natural starting fiber and then subjecting the fiber to a heat treatment with a copper compound, a reducing agent capable of reducing bivalent copper ions to monovalent copper ions, and a sulfur-containing compound capable of discharging a sulfur atom or sulfur ion for reaction with monovalent copper ions adsorbed by the fiber so that copper sulfide is impregnated into the fibers. Heat treatment with the sulfur-containing compound can be simultaneous with or separate from heat treatment with the copper compound and reducing agent. The electrically conducting fibers of the present invention have excellent conductivity, improved washability and are not plagued by the problem of static charging associated with the starting synthetic or natural fiber.
