Abstract

The invention discloses an active black dye. The active black dye comprises the following components in percentage by weight: 5-25% of active red dye compound as shown in formula I, 20-55% of active yellow dye compound as shown in formula II and 45-70% of active blue dye compound as shown in formula III, wherein X1, X2 and X3 are of Cl or F independently; and M1, M2 and M3 are of H or Na independently. The active black dye disclosed by the invention can significantly improve the deep dyeing property and the compatibility of the dye and has a better promoting property, the active black dye has the advantages of deeper dyeing depth, uniform dyeing and good promoting capability, dyeing can be performed at a low temperature, energy is saved and environmental pollution is further reduced. The formula I, the formula II and the formula III are shown in the description.

Description

A kind of reactive black dye

Technical field

The present invention relates to a kind of reactive black dye.

Background technology

Black and active dye is the kind that the application of reactive dyestuffs field is more, output is larger, if C.I. reactive black 5 # is one of kind of current output maximum.

Considerable is in the market that mode with three primary colors blending obtains the reactive black kind with some superiority.But exist such as pitch black degree not, cannot reach depth requirements; Each component property difference is large, and the deficiency that compatibleness is not good etc., is the difficult problem facing in reactive dyestuffs field.

Summary of the invention

Technical problem to be solved by this invention is that to have overcome the pitch black degree that existing reactive black dye exists inadequate, cannot reach depth requirements, each component property difference is large, the defect that compatibleness is not good, and a kind of new reactive black dye is provided, by its each component is redesigned, all introduce double-active group, greatly improved its dyeing behavior, as remarkable, improved depth and the compatibleness of dyestuff, and there is preferably enhancing, can meet the current demand to reactive black dye.

Therefore, the present invention relates to a kind of reactive black dye, it comprises the component of following mass percent: suc as formula the active red dye compound 5 ~ 25% shown in I, and suc as formula the reactive yellow dye compounds 20 ~ 55% shown in II, and suc as formula the reactive blue dye compound 45 ~ 70% shown in III.

Wherein, X ¹, X ²and X ³be Cl or F independently; M ¹, M ²and M ³be H or Na independently.Distinguishingly, without acidifying in the situation that, M in above-mentioned general formula compound ¹, M ²and M ³be Na, above-mentioned general formula compound all exists with the form of sodium salt.

Therefore, above-mentioned general formula compound I can be I(1) or I(2);

Above-mentioned general formula compound II can be II(1) or II(2);

Above-mentioned general formula compound III can be III(1) or III(2);

The invention further relates to the preparation method of above-mentioned reactive black dye, the blending device that uses this area routine by said ratio suc as formula the active red dye compound shown in I, suc as formula the reactive yellow dye compounds shown in II, and mix suc as formula the reactive blue dye compound shown in III; The auxiliary agent that as required, can suitably add this area routine is to adjust the performances such as the intensity of reactive black dye and dissolving.

The invention still further relates to the preparation method of another reactive black dye, use the synthetic method of published reactive red (I) in this area, reactive yellow (II), these three kinds of compounds of Reactive blue (III) to obtain respectively after corresponding solution, with spectrophotometer method, determine respectively concentration, under liquid state, be fully mixed and made in proportion reactive black dye liquid, according to the method for commercialization dyestuff conventional in this area, obtain solid state powder shape commercial dye.

Reactive black dye of the present invention can dye by the dyeing of this area routine (accompanying drawing 1).Preferably dyeing condition is as follows: dye dosage is 2%(owf), at 40 ℃ of dyeing 90 minutes, soda ash consumption 5g/L, amount of caustic soda 1g/L.

Without prejudice to the field on the basis of common sense, in the present invention, above-mentioned each preferred feature can arbitrary combination, obtains the preferred embodiments of the invention.

Raw material described in the present invention or reagent except special instruction, equal commercially available obtaining.

Positive progressive effect of the present invention is: reactive black dye of the present invention has significantly improved depth and the compatibleness of dyestuff, and there is preferably enhancing, this reactive black dye dye level is darker, even dyeing, lifting force is good, can dye at low temperatures, save the energy and reduced the pollution to environment.
