Abstract
The invention relates to the disperse dye technology field, and provides a dark disperse dye composition and applications to overcome defects that types of dark disperse dyes with single structures are not many, the deep dyeing property and elevating power are insufficient and the fastness performance is poor in present disperse dyes. The composition is composed of, by weight, 5-95 parts of dye A, 5-95 parts of dye B and 0-35 parts of dye C. The composition has excellent dyeing performances.
Description
Technical field
The present invention relates to technical field of disperse dyes, relate in particular to a kind of deep color dispersion dyes composition and application.
Background technology
Recently, along with the development of terylene, trevira and BLENDED FABRIC thereof, also more and more higher to the performance requriements of dispersed dye.In existing conventional disperse dyestuff, the deep color dispersion dyes kind that structure is single is few, and such dyestuff often exists depth and lifting force are not enough, fastness ability is poor shortcoming, and the velocity ratio of dispersed dye new texture exploitation is comparatively slow, therefore carries out commercialized technology process to existing procucts and seems further important.General deep color dispersion dyes is carrying out in dyeing and heat setting process or other postfinishing process, due to the situation such as the dyeing behavior of dyestuff own is not good, therefore, find the admixture of disperse dyes having excellent dyeability energy more, for improving the using value of deep color dispersion dyes and promoting commodity market, there is very important meaning.
Summary of the invention
For solving in existing dispersed dye, the deep color dispersion dyes kind that structure is single is few, and there is the shortcoming that depth and lifting force are not enough, fastness ability is poor, the present invention proposes a kind of deep color dispersion dyes composition and application, composition has excellent dyeability energy.
The present invention is achieved by the following technical solutions: a kind of deep color dispersion dyes composition, described composition is made up of dyestuff A, dyestuff B and dyestuff C, wherein the weight part of dyestuff A is 5 ~ 95, and the weight part of dyestuff B is 5 ~ 95, and the weight part of dyestuff C is 0 ~ 35.
As preferably, described composition is made up of dyestuff A, dyestuff B, dyestuff C, and the weight part of dyestuff A is 5 ~ 90, and the weight part of dyestuff B is 5 ~ 90, and the weight part of dyestuff C is 1 ~ 35.

As preferably, by following structural formula, one or more form dyestuff C:
The application of a kind of deep color dispersion dyes composition of the present invention in hydrophobic textile material printing and dyeing, application in the printing and dyeing of especially polyester material, comprise dyeing and the stamp of the textile materials of hydrophobic fibre blending that is semi-synthetic or that synthesize, this kind of textile materials can dye in any one form, comprises fiber, yarn or nonwoven fabric or textile fabric or knit goods.
A kind of deep color dispersion dyes goods are made up of deep color dispersion dyes composition and auxiliary agent.Deep color dispersion dyes composition of the present invention, usually needs to add auxiliary agent and disperses in commercialization.Such as, after being mixed by above-mentioned proportioning by the dye monomer compound represented by component A ~ C, under the existence of auxiliary agent, water or other wetting agent, carry out corpusculed with the pulverizer such as sand mill or shredder; Also mix with above-mentioned ratio after the dye monomer compound represented by component A ~ C can being carried out corpusculed process with the pulverizer such as sand mill or shredder respectively under the existence of auxiliary agent, water or other wetting agent in addition.Due to the singularity of dye industry, be difficult to also there is no need to make sterling, usually can with the impurity in some preparation process.Therefore, disperse dye composition of the present invention, when making dye preparations, main containing dye component and auxiliary agent, also allow the physical impurity containing a small amount of moisture and trace.In described disperse dye composition, the mass ratio of auxiliary agent and dye composite is 0.2 ~ 5: 1, is preferably 0.3 ~ 5: 1.
Described auxiliary agent be dispersed dye commercialization or aftertreatment time conventional dispersion agent, diffusant and tensio-active agent etc., can be one of following or several arbitrarily mixtures: naphthalene sulfonic acidformaldehyde condensation product, sulfonated lignin, alkyl naphthalene sulfonic acid formaldehyde condensation products, benzyl naphthalene sulfonic formaldehyde condensation compound, concrete example as condensation compound of methyl naphthalene sulfonic acid and formaldehyde (Dispersant MF), naphthalene sulfonic acidformaldehyde condensation product (dispersing agent NNO), benzyl naphthalene sulfonic formaldehyde condensation compound (dispersing agent CNF), sodium lignosulfonate (xylogen 85A, xylogen 83A) etc.
Dispersed dye goods of the present invention, can adopt common dip method, pad-dyeing method dyes, also can be used for direct printing.Wherein, common dip method, as polyester textile is carried out pre-treatment, is put into dye vat and is contaminated, and dye finishes, and cold water cleaning is to neutral, and strand is dry, then carries out reduction clearing, dries; Direct printing, as fabric is carried out dye pre-treatment, is dried, and setting, printing machine prints dispersed dye mill base, then evaporates, and utilizes the dye fixing that decatize mode makes on fabric, finally washes, stentering forming.
Compared with prior art, the invention has the beneficial effects as follows:
(1) there is the features such as depth is good, lifting force is excellent, colour fastness is good,
(2) during dyeing, dye dosage is few, contributes to saving dyestuff use cost.
