Abstract (en)
[origin: WO0192634A1] The invention relates to a method for coloring non-cationically modified polyacrylonitrile fibers during the spinning process when the fibers are in a gel state. The novel method is characterized in that at least one anionic colorant selected from the group of acidic, direct or reactive colorants is used and yields colorations of a large depth of shade with favorable general color fastnesses.
