Problems solved by technology

When the active orange dye composition described in the invention is applied to dyeing and printing of cellulose fibers or materials containing cellulose fibers, the dyeing stability is good, the color is bright, and the fastnesses are such as washing resistance, friction resistance, perspiration resistance and water resistance. Chlorine water color fastness has been improved, but there is still room for improvement

Embodiment 1

[0051]Mix 45 parts of dyes conforming to formula (1-1), 50 parts of dyes conforming to formula (2-1), 5 parts of dyes conforming to formula (4-1), and 5 parts of sodium sulfate to obtain a composite active orange dye. , This dye has high solubility and can print and dye cellulosic fiber materials into orange with good leveling and washing fastness.

Embodiment 2

[0053]Mix 48 parts of dyes conforming to formula (1-4), 55 parts of dyes conforming to formula (2-1), 6 parts of dyes conforming to formula (4-1) and 1 part of dustproof agent DL-6808 to obtain a composite Reactive orange dye. This dye has high solubility and can print and dye cellulosic fiber materials into orange with good leveling and washing fastness.

Embodiment 3

[0055]Mix 50 parts of dyes conforming to formula (1-2), 45 parts of dyes conforming to formula (2-1), 5 parts of dyes conforming to formula (4-3) and 5 parts of sodium sulfate to obtain a composite reactive orange dye. , This dye has high solubility and can print and dye cellulosic fiber materials into orange with good leveling and washing fastness.

Abstract

The present invention relates to a reactive inkjet printing dye mixture, comprising at least one dyestuff of formula (1), and optionally at least one dyestuff of formula (2), and / or at least one optional formula ( 3), and / or optionally at least one dye of formula (4), wherein M 1 , M 2 , M 3 , M 4 Each independently is H or sodium or potassium; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 At least one is a fiber reactive group; T 1 for halogen. The composite reactive dye mixture of the present invention can make colored fabrics have high level dyeing property, high color fixation rate, and achieve unprecedented solubility, which can be better applied to inkjet printing in automatic pulping system, and at the same time, unfixed dyes are easier to wash net.

Description

Technical field[0001]The invention belongs to the field of fine chemicals, and relates to a composite reactive dye, in particular to a reactive inkjet printing dye mixture and its application in the printing and dyeing of cotton, hemp, yarn, silk, wool and polyamide fibers.Background technique[0002]At present, the dye industry is fiercely competitive, and environmental issues are getting more and more attention. Automatic pulping systems and inkjet printing have become the development trend; customers have put forward higher requirements for product performance, especially the solubility of dyes. At present, the solubility of common reactive dyes in the market cannot meet the requirements of inkjet printing. In addition, the actual utilization rate in the dyeing process is not high, and a large part of it is hydrolyzed. In addition, the dyeing water consumption is very high in the traditional middle and high temperature dyeing. It consumes a lot of energy and needs to add a lot of s...
