Technical Field

The invention relates to the field of dyes, in particular to a high-fastness reactive yellow dye.

Background

Along with the increasing requirements of people on wearing comfort and ecological health, textile products are more and more concentrated on cotton fabrics, and the demand of reactive dyes is increased, so that the reactive dyes become one of the most widely applied synthetic dyes at present.

How to make the dye have higher fixation rate and promotion is one of the current development directions of the reactive dye. Because of the high lifting force, the usage amount of the dye is relatively reduced when the high-dyeing-depth printing and dyeing is carried out, and the high fixation rate can shorten the soaping-off process in the traditional fiber dyeing process, thereby shortening the whole printing and dyeing time and reducing the dyeing cost. After the single-color dye is used for printing and dyeing fibers, various performance indexes are difficult to meet the requirements of people. Therefore, the compound application of two or more dyes becomes the research direction of people.
