Abstract

The invention discloses a dye mixture for fur dyeing. The dye mixture consists of a dye component and an auxiliary component and dyes the fur by a discharge dyeing technology to obtain better color tone and perfect white discharge property; and the problem of limited varieties with good white discharge property suitable for fur is solved. The dye mixture has good color fastness after discharge, ironing fastness of level 4-5, rubbing fastness of level 5, light fastness of level 5, high dye-uptake and good white discharge property; and moreover, the monomer has bright color tone, the dye mixture has pure color tone, for example, the black color tone has good black degree, and the quality of fur can be obviously improved in application.

Description

technical field [0001] The invention belongs to the technical field of dye development, in particular to a dye mixture for fur dyeing. Background technique [0002] The dyes used for fur dyeing should have good solubility, uniform and firm coloring, not easy to fade and change color, and the operation is harmless and non-dangerous. The requirements for dyeing conditions are not harsh. Commonly used dyes are acid dyes, metal complex dyes, reactive dyes, oxidation dyes. When discharge dyeing is particularly needed, acid dyes and other dyes are usually used for dyeing. Many dyes fail to meet the dyeing requirements, the dyeing chromatogram is incomplete, and the requirements for shade and quality indicators cannot be met. Therefore, how to adapt to the discharge dyeing process and to have dyes of various shades is an urgent problem to be solved. The present invention thus comes. Contents of the invention [0003] The object of the present invention is to provide a dye mix...
