Problems solved by technology

[0002] With the continuous improvement of people's living standards in the world, people have higher and higher requirements for the ecological and environmental protection of clothing, and the requirements are getting closer to the level of the original ecology. The requirements for chemicals on textiles are becoming more and more stringent, especially for exports to Western European countries. The chemical requirements on textiles are even more stringent, so in recent years there have been many banned carcinogenic and allergenic disperse dyes, such as the ban on the export of allergenic Disperse Yellow 54, which limits the choice of dyes for printing and dyeing factories

Abstract

The invention discloses an ecological non-allergenic disperse golden yellow dye, which comprises the following components in percentage by mass: 0.1-75% of one or a mixture of two of a dye monomer A shown as a formula (I), 0.1-50% of a dye monomer B shown as a formula (II) and a dye monomer C shown as a formula (III), and the balance of an auxiliary agent. The disperse golden yellow dye does not cause cancer or sensitization, has excellent application performance, and provides more dye selections for printing and dyeing plants.

Description

technical field [0001] The invention belongs to the technical field of dyes, in particular to an ecological non-allergenic disperse golden dye and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards in the world, people have higher and higher requirements for clothing eco-environmental protection, and the requirements are getting closer to the level of the original ecology. The requirements for chemicals on textiles are becoming more and more stringent, especially for exports to Western European countries. The chemical requirements on textiles are even more stringent, so in recent years there have been many banned carcinogenic and allergenic disperse dyes, such as the ban on the export of allergenic Disperse Yellow 54, which limits the choice of dyes for printing and dyeing factories . For this reason, it is imperative to research and develop non-allergenic disperse golden yellow dyes that not only have ex...
