Problems solved by technology

[0003] Black reactive dyes are the most widely used and produced varieties of dyes. At present, most of the dyes used in the market are compounded by adding orange components to C.I. reactive black 5, but there is still a color fixation rate in the dyeing process. It has low dyeing and deepness, and there are also problems such as poor washing performance and serious color sticking

Embodiment 1

[0036] Mix 80 parts of the dye of formula (1), 20 parts of the dye of formula (2) and 1 part of the dye of formula (3) and fully mechanically mix to obtain the composite reactive black dye of the present invention. High level dyeing property, high color fixation rate, high jet black fullness and good deep dyeing black.

[0037] Exhaust dyeing: Dissolve 1g of the dye prepared in Example 1 with an appropriate amount of water, then set the volume in a 250mI volumetric flask, absorb 50mI of the dye solution and mix it with 50mI of water, then add 5g of cotton cloth and 6g of sodium sulfate. Then increase the temperature to 60°C at a rate of 1°C / min, keep it for 30 minutes, add 2g of sodium carbonate, and keep it at 60°C for 30 minutes, then take out the dyed cotton cloth and boil it with non-ionic detergent boiling soap for 15 minutes, then wash it with water and dry it. Dry at around 70°C.

Embodiment 2

[0040] Mix 70 parts of the dye of formula (1), 25 parts of the dye of formula (2) and 5 parts of the dye of formula (3) and then fully mechanically mix to obtain the composite reactive black dye of the present invention. High level dyeing property, high color fixation rate, high jet black fullness and good deep dyeing black.

[0041] Exhaust dyeing: first fully dissolve 1g of the dye prepared in Example 2 with an appropriate amount of water, then set the volume in a 250ml volumetric flask, absorb 50ml of the dye solution and mix it with 50ml of water, then add 5g of cotton cloth and 6g of sodium sulfate. Then increase the temperature to 60°C at a rate of 1°C / min, keep it for 30 minutes, add 2g of sodium carbonate, and keep it at 60°C for 30 minutes, then take out the dyed cotton cloth and boil it with non-ionic detergent boiling soap for 15 minutes, then wash it with water and dry it. Dry at around 70°C.

Abstract

The invention belongs to the technical field of dyes and particularly relates to a compound reactive black dye. The compound reactive black dye is prepared from, by weight, 50-100 parts of dyes in theformula I, 5-45 parts of dyes in the formula II and 0-5 parts of dyes in the formula III. The invention further provides a black dye compound which comprises a fixing alkali agent, a dye promoting agent and the above compound reactive black dye. The compound reactive black dye has high dyeing depth, good fixation rate and washing property and has low raw material cost; dyed fabric compounded by the Tibetan cyan dyes in the formula I, the orange dyes in the formula II and the yellow dyes in the formula III has high uniformity, high color fixation and high fastness, unprecedented black fullnessand dyeing depth are achieved, the washing property of the dye is increased, and problems of poor washing property of an existing reactive black dye, serious color sticking and the like are solved; the compound reactive black dye is suitable for dyeing, pad dyeing and anti-dyeing printing of fiber materials.

Description

technical field [0001] The invention belongs to the technical field of dyes, and in particular relates to a composite reactive black dye and its application. Background technique [0002] In recent years, with the rapid development of composite dye technology, composite reactive dyes have become more and more widely used. Mixing different reactive dyes can play a synergistic role. [0003] Black reactive dyes are the most widely used and produced varieties of dyes. At present, most of the dyes used in the market are compounded by adding orange components to C.I. reactive black 5, but there is still a color fixation rate in the dyeing process. It has low dyeing and deepness, and there are also problems of poor washing performance and serious color sticking. Contents of the invention [0004] In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a composite reactive black dye and its application, which not ...
