Abstract

The invention relates to a dark colored reactive dye with high fixation rate, belonging to the technical field of chemical dyestuff. The dark colored reactive dye consists of dark blue, red and yellow reactive dyes. The dye is characterized by comprising dark blue, red and yellow components in structures shown in general formulae. The three-primary-color reactive dye comprises the following components in ratio by weight: dark blue: red: orange=(50-80):(6-25):(6-20). The dark colored reactive dye provided by the invention is applicable to dyeing natural fibers such as cotton, hemps and regenerated fibers and is also applicable to dyeing protein fibers and polyamide fibers. The textile fibers can be in various forms such as fibers, yarns, fabrics or knitted goods. Dip dyeing means that the dyed object is absorbed in a dye bath with an appointed formula and then is fixed by alkali treatment, wherein the dyeing and fixing temperature is 50-70 DEG C. The leveling property of the dye is better promoted, the three components are good in compatibility, the colored light in a dyeing process is relatively stable, and the dye has good pitch-black degree.

Description

The dark black active dyestuff with high colour-fast rate

Technical field

The present invention relates to chemical dyestuff technical field, especially a kind of reactive dyestuffs of field of fine chemical.

Background technology

Black and active dye is in dyestuff, to apply the kind more, output is larger.Since 21 century, a large amount of reactive black patents is come out, but up to now, in commodity reactive dyestuffs, the overwhelming majority is still and take C.I. reactive black 5 as navy component, composite with redness and yellow color component, obtains the good reactive black of pitch black degree.Cibacron Black WNN for example, Cibacron Supra Black G, Supra Black R etc.The advantage of these dyestuffs, except DYED FABRICS has good pitch black degree, also has and dyes that curvilinear trend is consistent on trichromatic, and consistency is better etc.In this relevant patent, there is CN200510047135.4, CN200510047136.9, WO2004069937, US6537332, USP5849887 etc.

But the degree of fixation of dyestuff only has 60%～65% during above-mentioned dyestuff main not enough, the colourity of dyeing residual liquid is high, and the dyestuff of a large amount of not sets and hydrolysis remains in dyeing waste liquid, has not only affected economic benefit, and has caused environmental pollution.

Summary of the invention

Improving reactive black degree of fixation, reduce dyestuff content in dyeing waste liquid, is the main purpose that the present invention improves black and active dye.

The invention provides one group and there is the polycomponent composite black active dye that good dyeing behavior, pitch black degree, level-dyeing property and lifting force are good, degree of fixation is high, synthetic three primary colors component convenient, that raw material is easy to get forms.At least by the navy component of following general formula (1), the magenta component of general formula (2), the Yellow active dye of general formula (3) forms.Its performance characteristic is compatibleness and the lifting force that each component dyestuff is good.Its DYED FABRICS has excellent pitch black degree and uniform dyeing property.

Composite dye constitutional features of the present invention is that the structure of three primary colors component dyestuff has very approaching wetting ability, lipophilicity, wherein comprises navy, magenta and the orange-yellow component of following general formula.

Dark blue reactive dye component is the structure shown in general formula (1):

R ₁=H, CH3, OCH ₃, SO ₃m or Cl;

The proportioning of above-mentioned three primary colors reactive dyestuffs component is, dark blue: magenta: orange weight percent is (50～80): (6～25): (6～20).

As the active diazo component of Huang, product, blue or green three primary colors component dyestuff as (01-13) of benzene compounds:

The structure of navy component dyestuff has general formula (1) constitutional features above.

Red component dyestuff is at least one or two orchil of have general formula (2) or following dyestuff 201-207 feature.For example, below:

At least one or two have the structure of formula (3) yellow color component dyestuff.Be exemplified below row dyestuff (301-308):

Above-mentioned diazotization, the couling process preparation of respectively organizing dyestuff can be conventional.If desired can be concentrated by membrane sepn desalination, with the dyestuff of the high density made.

Black dyes can be composite by a certain percentage by orange, pinkish red, dark blue component, makes the reactive black of high colour-fast rate.Each component of three primary colors can be a dyestuff, can be also the mixture of two dyestuffs.The feature of gained reactive black is that the consistency of three primary colors component is good, and dyeing speed approaches, and degree of fixation is high, and the colourity at the residual night of dyeing is more shallow.Composite method can be that each component powder dye (dry method) in mixing machine mixes mutually, and after also can again dissolving by designated ratio, (wet method) spraying is dry.

The ratio range of dark blue, pinkish red, orange three primary colors component is generally (50～80): (6～25): (6～20).

Beneficial effect of the present invention, with respect to prior art, black plyability reactive dyestuffs of the present invention are suitable for dying natural fiber, as cotton, fiber crops, regenerated fibre, are applicable to too protein fibre and tynex.Above-mentioned textile fiber can take various forms, as fiber, yarn, fabric or tricot.Dip-dye is after pollutant is adsorbed in the dye bath of specified mix, then uses alkaline purification fixation, and dyeing and color fixing temperature are 50～70 ℃, the level-dyeing property of this dyestuff, promote, and the compatibleness of three components is good, and in dyeing course, coloured light is more stable, has good pitch black degree.
