Abstract: Fiber material composed of acid-modified homopolymers or copolymers of acrylonitrile (PAC fibers) which has been obtained by a wet spinning process, has not been dried and is still in a swollen condition (gel form), can be dyed advantageously and in fast colors by means of soluble dyes, the molecule of which contains several groups, namely more than one quaternary grouping and/or a strongly basic grouping carrying no charge, which exert a basic action towards the acid groups of the fiber substance. The chromophore of this colorant can belong to the category of monoazo or diazo dyes, methine, azamethine or diazamethine dyes or naphthalactam dyes.In accordance with the invention, after substantially removing the non-aqueous spinning solvent by washing, the spun material, as a moist gel, is dyed continuously or discontinuously from an aqueous dyebath; the fibers can be stretched before the dye is applied, during the dyeing process itself or immediately afterwards.By virtue of their special nature, the dyes of the type designated above, which have a strong fixing action, produce optimum fixing rates when dyeing PAC gels and, in the subsequent production stages, do not cause any noticeable soiling, as a result of dye which has bled out, on components of machines and operating baths, such as stretching or after-treatment baths. Investigations of penetration of the fiber by the dye, of the fixing rate and of the resulting fastness properties, such as fastness to wet processing, have shown no disadvantages compared with conventional dyes.

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.
