PURPOSE:To continuously, uniformly dye a protein textile product compactly with a low energy consumption to high-chroma, clear color with extremely high fastness without causing tailings. CONSTITUTION:Firstly, a dyeing liquid is prepared at room temperature by dissolving in water (A) an anionic reactive dye having (1) skeleton consisting of copper phthalocyanine group and a group reactive with amino group and (B) an urea compound. Second, a hydrophilicized protein textile product is immersed in this dyeing liquid, dehydrated, and then left to stand at room temperature under a specified moisture content thereof. The textile product is then put to soaping. Instead of the above hydrophilicization, the protein fibers may be modified by dissolving a breaking promoter for the cystine linkages in the protein textile product when the dyeing liquid is prepared. The above-mentioned reactive group is pref. vinylsulfone group, monofluorotriazine group or difluoromonochloropyrimidine group. |
