ABSTRACT:
A process for dyeing polyolefin fiber materials, which comprises contacting a polyolefin fiber material obtained by melt-spinning a mixture of crystalline polyolefin and 0.1 to 30% by weight based on the weight of the polyolefin of a copolymer of ethylene and an aminoalkyl acrylate compound represented by the formula, ##STR1## wherein R.sub.1 represents hydrogen atom or methyl group, R.sub.2 and R.sub.3 each represents hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and n represents an integer from 1 to 4, or a blend product of the said polyolefin fiber material and a polyamide fiber material, with a dye bath containing an anionic dye and at least one carboxylic acid selected from the group consisting of benzoic acid, salicylic acid, p-chlorobenzoic acid and 5-chlorosalicylic acid.
