When methoxyl group is connected with phenyl ring, methoxyl group becomes electron-donating group, and therefore when methoxyl group is introduced at the amino ortho position of component F coupling component, the hyperchromic effect of component F strengthens.
Preferably, by massfraction, the massfraction of described component A is 4%, the massfraction of described B component is 3%, and the massfraction of described component C is 4%, and the massfraction of described component D is 4%, the massfraction of component E is 30%, and the massfraction of described component F is 1%, and all the other are auxiliary agent.
It should be noted that; due to the singularity of dye industry; described component A ~ F is difficult to also there is no need to make sterling, and usually can contain the physical impurity of a small amount of moisture content and trace, the existence of this part moisture content and physical impurity is within tolerance range of the present invention.
Dye mixture of the present invention can be obtained by preparation method conventional in the industry, such as, after component A ~ F being mixed by the proportioning preset, under the existence of auxiliary agent (comprising dispersion agent, water or other wetting agents), carry out corpusculed with the shredding unit such as sand mill or shredder, namely obtain described dye mixture; Also first component A ~ F can be carried out corpusculed with the shredding unit such as sand mill or shredder respectively under the existence of auxiliary agent (comprising dispersion agent, water or other wetting agents), then mix according to the proportioning preset, namely obtain described dye mixture.
Compared with prior art, beneficial effect of the present invention is:
(1) do not contain anthraquinone dyes in dispersed black dye mixture of the present invention, all adopt azo dyes, not only produce easy, cheap, and dyefastness is better;
(2) contain heterocycle in component C of the present invention, and heterocycle also has electron-withdrawing group-NO
2, heterocycle and replace having to be beneficial to and improving the coloring intensity of component C of nitro, makes component C have good hyperchromic effect.And component F introduces cyano group and non-Br at the diazo ortho position of diazo component, this is because the electron-withdrawing power of cyano group than-Br more by force, and electron-withdrawing power is stronger, and hyperchromic effect is more remarkable; The existence of component C and component F makes dispersed black dye mixture of the present invention can obtain excellent dye uptake and dyestuff fastness, and dye uptake reaches as high as 94%;
(3) when not increasing component C and component F consumption, the consumption of component A, B, D and E reduces all to some extent, greatly reduces the production cost of dye mixture.
