Process for dyeing polyolefin fiber materials |
摘要 |
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, <IMAGE> wherein R1 represents hydrogen atom or methyl group, R2 and R3 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.
