Description

A kind of blue disperse dye mixture and disperse dyes

Technical field

The present invention relates to a kind of blue disperse dye mixture and disperse dyes, particularly relate to a kind of terylene and blending is knitted The blue disperse dye mixture of thing printing and dyeing and disperse dyes.

Background technology

Raising textile required along with fast development and the people of polyester Fresh fats in recent years, correspondingly, to dyestuff this Dyeability, environmental-protecting performance that body has it is also proposed higher requirement.I.e. require that dyestuff has high lifting force and every dyeing Fastness.

For disperse dyes, the work of large-scale development new dye structure is the rarest, and substantial amounts of work turns to Between the application performance of dyestuff, dyestuff and dyestuff with in the research of the compound synergic of auxiliary agent.But from existing compounding dyestuff Kind is seen, its dyeing application performance such as compatibility and repeatability still can not fully meet demand.

Summary of the invention

For solving disperse dyes compatibility and the deficiency of poor reproducibility in prior art, we have proposed a kind of terylene and The blue disperse dye mixture of blend fabric printing and dyeing and disperse dyes, its purpose: synchronize colouring property good, compatibility is good, reproduction Property is good.

For reaching above-mentioned purpose, technical scheme is as follows:

A kind of blue disperse dye mixture, by one or more structures component A as shown in formula I and one or more knots Structure such as formula II or/and (III) or/and component B shown in (IV) composition, based on described component A and component B, described component A weight Mark is 1-99%, and described component B weight fraction is 1-99%；

In formula I, X, Y each stand alone as hydrogen or halogen, cyano group, nitro；

R1, R2, R3 each stand alone as methyl, ethyl, propyl group, cyanoethyl or acetyl group；

In formula II, R4 each stands alone as hydrogen methyl or nitro, and R5, R6, R7 each stand alone as hydrogen, ethyl, propyl group, cyanogen second Base, acetyl group etc.；

In formula III, R8 each stands alone as hydrogen methyl or nitro, and R9, R10, R11 each stand alone as hydrogen, ethyl, propyl group, cyanogen Ethyl, acetyl group etc..

Preferably, based on described component A and component B, described component A weight fraction is 50-99%, described component B weight Amount mark is 1-50%.

It is further preferred that based on described component A and component B, described component A weight fraction is 70-99%, described Component B weight fraction is 1-30%.

Preferably, described component A is one of following or two of which or two or more mixture:

Preferably, described component B is compound ii or/and III or/and one of IV or two or more mixture:

Preferably, when described component B is compound (III-1) and compound (IV), component A is two or more structure Mixture as shown in formula I:

R1, R2, R3 each stand alone as methyl, ethyl, propyl group, cyanoethyl or acetyl group.

Due to the particularity of dye industry, it is difficult to also there is no need to make sterling, it will usually with in some preparation process Impurity, the disperse dyes of the present invention allow also to the moisture containing a small amount of and the physical impurity of trace when making finished product.

The disperse dyes of the configuration present invention, the dye composition of the formula I used～(IV) can be easily by this area Mode known to technical staff synthesizes, it is possible to use commercial goods.

The disperse dyes of the present invention, need to be carried out point as generally needed to be added auxiliary agent through commercial treatment when being applied to dyeing Dissipate.Such as after the former dyestuff represented by component A, component B being mixed by above-mentioned proportioning, at auxiliary agent, water or other wetting agents In the presence of carry out corpusculed with the pulverizer such as sand mill or grinder；The most also can be by the former dye represented by component A, component B With above-mentioned after expecting to carry out corpusculed process with sand mill or grinder in the presence of auxiliary agent, water or other wetting agents respectively Ratio mixes.Generally, auxiliary agent and former dyestuff weight ratio are 0.8～5:1.

Described auxiliary agent is dispersant, the diffusant etc. that disperse dyes are conventional when compounding, one of the most following or it is any Several mixture: naphthalene sulfonic acid-formaldehyde condensation product, alkyl naphthalene sulfonic acid formaldehyde condensation products, card base naphthalene sulfonic acid-formaldehyde condensation product, wooden The anionic dispersing agents such as element sulfonate.Specifically, naphthalene sulfonic acid-formaldehyde condensation product such as dispersing agent NNO, alkyl naphthalene sulfonic acid formaldehyde condensation Thing such as dispersing agent MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde), card base naphthalene sulfonic acid-formaldehyde condensation product such as dispersing agent CNF etc., sulfomethylated lignin Hydrochlorate such as sodium lignin sulfonate (such as commercial dispersants Reax83A, Reax85A) etc..

The invention still further relates to a kind of dispersed blue dye, described dispersed blue dye combination add auxiliary agent and make, described in help Agent and described dye mixture weight ratio are 0.8～5:1.

Preferably, the raw material weight composition preparing described disperse dyes is as follows:

The blue disperse dye mixture of the present invention, after commercial treatment, can with the liquid after corpusculed, emulsifiable paste state or Person's spray drying method etc. be dried after powdery, graininess supply dyeing.Admixture of disperse dyes system by the present invention Dyes Polyester Fibers time, by adjusting the ratio between different component, can obtain and have that coloured light is gorgeous, dispersibility The gorgeous indigo plant of the premium properties such as good, sun-proof, washable, perspiration resistance is to sapphire blue dyeing and weaving thing.
