ABSTRACT:
Electrically conducting acrylic and modacrylic fibers are prepared by subjecting the fibers to a first heat-treatment in a bath containing a copper compound and a reducing agent to adsorb monovalent copper ions within the fibers. The heat-treated fibers are washed thoroughly and then subjected to a second heat-treatment in the presence of a sulfur-containing compound to convert the adsorbed monovalent copper ions to copper sulfide. The electrically conducting fibers have superior conductivity which is not lost in repeated washings. The electrically conductive fibers can be dyed readily with cationic dyes without loss of electrical conductivity. The electrically conductive fibers of the present invention possess the touch and other physical characteristics of the starting acrylic or modacrylic fibers.
