Problems solved by technology

[0006] The more prominent contradiction between the above two points directly leads to the asynchronous dyeing time when reactive yellow 145 and reactive orange 82 are combined to dye cellulose fiber materials, resulting in poor shade reproducibility and high color flower rate

Abstract

A composite reactive yellow dye is characterized in that: in parts by weight, it is compounded from 60-99 parts of the dyes shown in the formula (1) and 1-40 parts of the dyes shown in the formula (2); (See the formula on the right) The dyestuff of the present invention has the advantages of stable performance, high solubility, high color fixation rate, good dyeing synchronization, good level dyeing property, good tone reproducibility, especially for deep color dyeing.

Description

technical field [0001] The invention relates to a reactive yellow dye, in particular to a composite reactive yellow dye. Background technique [0002] With the continuous development of cellulose fiber varieties and the continuous development of dyeing technology, when using reactive dyes to dye cellulose fibers, higher and higher requirements are put forward for the application performance of reactive dyes. Due to the coloring of fiber materials by single-color dyes, the comprehensive value of various performance indicators is difficult to achieve satisfactory results. For example, dyes with a structure similar to reactive yellow 145 are a kind of heterobiactive group (a chloro-s-triazine group and ethylene Sulfone-based) dyes, although it has higher color fastness to dyed fabrics after coloring cellulose fiber materials, but it has two more obvious shortcomings, that is, poor level dyeing and reproducibility, so two or More and more people in the industry pay more and mor...
