A commercial dye is prepared by mixing 60-75 percent of the gray reactive dye composition, 5-15 percent of a dispersing agent, 0.1-0.5 percent of a dust preventive, 5-10 percent of anhydrous sodium sulfate and 10-15 percent of a nonionic leveling agent. When a cellulose fiber fabric is subjected to pad dyeing by adopting the dye composition disclosed by the invention, the composition has the advantages of pure colored light, high lifting property, consistent color, zero head-tail difference and side middle difference and the like and replaces reduced dyes to perform pad dyeing, the process is convenient to control, and the cost is low.
Description
Technical field
The present invention relates to reactive dyestuff field, especially relate to the application that a kind of grey reactive dyestuffs of being made up of three components compound and this dye mixture carry out knot dyeing technology on cellulose base fiber fabric.
Background technology
Advantages such as reactive dyestuffs are complete, bright-colored with its chromatogram, excellent property, suitability are strong and being developed rapidly, because current China is further strict for the protection of environment, advocate energy-saving and emission-reduction, eco-friendly friendly process energetically.COD in the wastewater flow rate produced for dyeings different reactive dyestuffs and waste water is very different, for the requirement due to bath raio exhaust dyeing, this kind of dyeing will produce a large amount of waste water, and the utilization ratio of exhaust dyeing technique dyestuff also not high (general double-active radical dye degree of fixation 60 ~ 80%), the dyestuff of a large amount of non-fixation is present in waste water, make the COD in waste water very high, and identical dyestuff adopts printing technology or knot dyeing technology to carry out painted, its degree of fixation will very high (generally more than 90%), the water yield produced also can be little, COD in waste water also can reduce, it is a kind of dyeing comparing environmental protection at present.
Secondly knot dyeing technology is very high to the requirement of dyestuff, is first that requirement reactive dyestuffs have very high solubleness and dissolution rate, also requires that dyestuff has good consistency and level-dyeing property, without problems such as differences in poor, limit end to end; In general grey reactive dyestuffs, during for knot dyeing technology, especially light-coloured prods, generally there is poor reproducibility, and the partially red phenomenon of color after dark lifting, especially grey black phenomenon is become with dark color obvious, active gray dyes commercially available at present only has reactive black 8, although this dye shade is better, be suitable for stamp and pad dyeing, its depth is bad, more importantly contain heavy metal---chromium and cobalt in its structure, belong to metallized dye, for environment or for healthy all will very large harm, belong to the dyestuff of European Union's forbidding.
Summary of the invention
For the problems referred to above that prior art exists, the invention provides a kind of grey reactive dye compositions and application thereof.When adopting dye composite of the present invention to carry out pad dyeing dyeing to cellulose base fiber fabric, there is pure color light, enhancing be good, uneven color is consistent, without end to end poor with limit in the advantage such as difference, vat dyes can be replaced to carry out pad dyeing dyeing, technique is convenient to control, with low cost.
Technical scheme of the present invention is as follows:
A kind of grey reactive dye compositions, formed by the compound blending shown in compound and general structure (III) shown in compound general structure (I) Suo Shi, structure formula II, the mass percent of each component is respectively 51 ~ 65%, 9 ~ 23%, 19 ~ 33%;

Described composition by 54 ~ 62% general structure (I) shown in compound, 12 ~ 20% structure formula II shown in compound and 22 ~ 30% general structure (III) shown in compound blending form.
A commercial dye prepared by described grey reactive dye compositions, the massfraction of contained raw material and each raw material is: grey reactive dye compositions 60 ~ 75%, diffusant 5 ~ 15%, dust-proofing agent 0.1 ~ 0.5%, Sodium sulfate anhydrous.min(99) 5 ~ 10%, nonionic leveler 10 ~ 15%.
Described diffusant is methyl naphthalene sulfonic acid or methyl naphthalene sulfonic acid class formaldehyde condensation products, and condensation degree is 1 ~ 4, sulfonation degree is 1 ~ 2; Dust-proofing agent is aqueous polymer; Non-ionic type levelling agent is ethylene oxide condensate, and condensation degree is 150 ~ 200.
Described commercial dye is used for the application that cellulose base fiber fabric carries out pad dyeing dyeing.Described cellulose base fiber fabric is the cellulosic fibre material of hydroxyl and/or nitrogen.Described cellulose base fiber fabric is cotton, viscose glue, fiber crops, silk, leather, poly-aminoacyl fiber or its multiple BLENDED FABRIC.
The technique effect that the present invention is useful is:
1, good, the good level-dyeing property of structural formula I in the present composition, the Compound Phase dissolubility shown in II, III, carry out composite by a certain percentage, obtain the gray dyes of pure color light, compound product solves partially red, the deep mixed problem caused of color and luster of commercially available active ash on coloured light; Also overcome the problem that its product is poor end to end, products production cost reduces, and does not have product can reach such effect on knot dyeing technology at present both at home and abroad simultaneously.
2, structural formula I, the compound shown in II, III in the present composition, it is all disazo dyes, the dyestuff of its corresponding construction can be obtained by common synthetic method, not containing heavy metal ion, belong to environment-friendly active dye, environment and HUMAN HEALTH are safe from harm, meet the standard of European Union, reactive black 8 and vat dyes can be replaced to carry out knot dyeing technology dyeing, decreasing pollution, technique is convenient to control, with low cost.
3, the present composition is according to supermolecular theory, utilizes the principle of blending synergy that the dyestuff of two or more similar is carried out composite mixing, can improve the physicalies such as the coloured light of dyestuff, solubleness, dissolution rate, Salt And Alkali Tolerance; Also can improve various fastness ability, as the chemical property of Exposure to Sunlight, washing, staining simultaneously.
4, composite between present composition principle a kind of dyestuff is regarded as the auxiliary agent of another kind of dyestuff, another kind of dye molecule surrounds by a kind of dye molecule, reduce the chance that similar dye molecule is collided, make chance minimizing of associating between congeneric elements, thus the solubleness of dyestuff is increased, the ability of alkaline-resisting, salt strengthens, reach the object of improving SNR, for another kind of dyestuff still.
5, the present invention is on the basis of lot of experiments, determine the dyestuff of similar and optimum dispersion solubility promoter that can be good with fastness, reactive dye compositions of the present invention mixes with auxiliary agents such as diffusant, dust-proofing agent, Sodium sulfate anhydrous.min(99), nonionic leveler, supplement and complement each other between each component, act synergistically, cellulosic fibre carries out pad dyeing comparatively ideal effect.
6, in the present composition each component to the substantivity of fiber relatively, colourability is synchronous, and that is consistency and level-dyeing property are all relatively good, can not produce without problems such as differences in poor, limit end to end, enhancing is also relatively good.
7, the present composition, can contaminate synchronously at light color and each composition of dark color, make grey product favorable reproducibility, the disposable accurate dyeing of printing and dyeing mill becomes possibility, adopt blue, red, orange three components, the component that only need add corresponding coloured light can realize the adjustment of printing and dyeing mill to product coloured light; For pad dyeing product, can replace vat grey, technique is convenient to control, with low cost.
