Abstract

The invention relates to an acidity dye mixture that includes three structures of dyes: one, the dye according with the general expression (I), or the metal salt, ammonium salt or organic ammonium salt according with the expression; two: the dye according with the general expression (II), or the metal salt, ammonium salt or organic ammonium salt according with the expression; three, C.I acid orange 67 or C.I acid yellow 242 in international dye index, or the metal salt, ammonium salt or organic ammonium salt of the two dyes. The invention could be used in the weak color coloration in polyamide fiber outside material and could satisfy general clothes outside material product quality index demand.

Description

technical field [0001] The invention relates to a dye, in particular to an acid dye mixture. The dye is used for light-colored dyeing of nylon fabrics, and can meet the quality index requirements for finished products of general garment fabrics in the world. Background technique [0002] As we all know, the dyeing quality of textile fabrics is directly related to the performance of dyes. At present, when printing and dyeing factories dye light-colored nylon fabrics, the gray dyes used are A-BL gray mixed with C.I. Acid Blue 324, C.I. Acid Yellow 199, and C.I. Acid Red 337. Although this kind of gray dye is mixed with three primary colors of acid blue, acid yellow and acid red with better application performance, the actual dyeing quality and effect are not as good as people imagined. Take the gray dye mentioned above as an example, its application performance: grade 2 for nylon staining, grade 2 for original change, grade 3 for light fastness, and changes color during heat ...
