Abstract

The invention provides a high light-fastness acid dye and a preparation method and application thereof. The high light-fastness acid dye is prepared from, by weight, 10-50 parts of acid dyes, 10-30 parts of an ultraviolet light absorber, 10-20 parts of a light stabilizer and 0-50 parts of nekal; the acid dyes are one or multiple of the following acid dyes of acid yellow 17, acid yellow 29, acid red 34, acid red 337, acid blue 25 and acid blue 324. The dye has higher light fastness and wet rubbing fastness at low concentration, and the dye is suitable for dyeing of all kinds of furs, the dyeingeffect is better particularly for white mink, dyeing is full, and the color is bright.

Description

technical field [0001] The invention relates to the field of dyes, in particular to an acid dye with high light fastness and application thereof. Background technique [0002] Dyes are compounds that impart color to fibers and other materials firmly. With the gradual improvement of social living standards, people have higher and higher requirements on the color of clothing, etc., so the research and development of dyes is more and more favored by many research and development personnel. Color fastness is one of the important indicators for evaluating dyes, including light fastness, soaping fastness and rubbing fastness, and rubbing fastness is further divided into dry rubbing fastness and wet rubbing fastness. [0003] In the related art, the light fastness and wet rubbing fastness of dyes at low concentrations are both low, and severe discoloration will occur after several hours of sunlight exposure or wet rubbing for several hours. According to statistics, the existing d...
