Abstract
A kind of economic and environment-friendly type disperse dyes, are related to a kind of composite disperse dye, including several dispersion dyes monomers and neutral inorganic monomer.Compared with prior art, anionic auxiliary agent is replaced by using substantial amounts of inorganic salts, so that the discharge of dyeing and printing sewage is greatly reduced, it ensure that disperse dyes, in coloured light and the reliability and stability of tint applications aspect of performance, had so not only saved production cost but also reduced the discharge in dyeing waste-water simultaneously.
Description
Technical field
The present invention relates to a kind of composite disperse dye, especially a kind of environmentally friendly disperse dyes.
Background technology
China is disperse dyes manufacturing nation maximum in the world, and its production needs to use anionic dispersing agent, consumption
More than 250,000 tons/year.At present, the anionic dispersing agent used mainly condensation compound of methyl naphthalene sulfonic acid and formaldehyde, such as dispersant
MF, molecular structural formula is as follows：
Naphthalene sulfonic acid-formaldehyde condensation product, such as dispersant NNO, molecular structural formula are as follows；
Benzyl naphthalene sulfonic acid-formaldehyde condensation product, such as dispersing agent C NF, molecular structural formula are as follows：
These dispersants circulate into dyeing waste water again after printing and dyeing, because these dispersants are difficult to decompose in nature,
Long-term use will necessarily cause greatly negative effect to environment；Dyeing is the important composition portion in textile industry industrial chain
Point, it is the crucial industry and bottleneck for lifting clothes, household textile quality and added value.Since 2000, textile and dyeing industry
While developing rapidly, environmental issue is also more protruded.The dyeing waste water of textile printing and dyeing industry discharge is China's industrial system
One of middle major polluting sources.According to statistics, the dyeing waste water of dyeing discharge accounts for 80% left side of national textile industrial discharge total amount
It is right.The problem of there is energy consumption in China's textile industry particularly printing and dyeing industry, water consume is high.Energy-saving and emission-reduction turn into DYE PRODUCTION enterprise
Middle frequency of use highest noun, the management objectives as governments at all levels and industry, dye industry faces unprecedented pressure.Cause
This, how " energy-conservation, emission reduction, consumption reduction, synergy ", be that each dyestuff manufactory is worth the long-standing problem of thinking, it is suitable to develop
Economic and environment-friendly type disperse dyes are also needed for dyestuff factory meets printing and dyeing mill's survival and development.
The content of the invention
The present invention is for of the prior art not enough there is provided a kind of economic and environment-friendly type disperse dyes, by using a large amount of
Inorganic salts replace anionic auxiliary agent so that the discharge of dyeing and printing sewage is greatly reduced, while ensure that disperse dyes in color
The reliability and stability of light and tint applications aspect of performance, had so not only saved production cost but also had reduced the row in dyeing waste-water
Put.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of economic and environment-friendly type point
Dissipate dyestuff, it is characterised in that including several dispersion dyes monomers and neutral inorganic monomer.
In above-mentioned technical proposal, it is preferred that also including auxiliary agent.
In above-mentioned technical proposal, it is preferred that described neutral inorganic monomer is sodium sulphate, potassium sulfate, sodium chloride or chlorine
Change the one of which of potassium.
In above-mentioned technical proposal, it is preferred that described auxiliary agent includes condensation compound of methyl naphthalene sulfonic acid and formaldehyde, naphthalenesulfonateformaldehyde formaldehyde and contracted
Compound, benzyl naphthalene sulfonic acid-formaldehyde condensation product, the one or more of lignosulfonates.
In above-mentioned technical proposal, it is preferred that by weight percentage, including the disperse dyes list described in 3%-65%
The inorganic salt monomer of body, 20%-56%, the auxiliary agent described in 15%-50%.
In above-mentioned technical proposal, it is preferred that by weight percentage, including the disperse dyes list described in 15%-30%
The inorganic salt monomer of body, 30%-50%, the auxiliary agent described in 20%-40%.
In above-mentioned technical proposal, it is preferred that described dispersion dyes monomer includes：
One or more.
The present invention relates to the dyestuffs such as quinolines, monoazo class and neutral inorganic composition, it mainly includes disperse dyes
Monomer, inorganic salt monomer and auxiliary agent.The present invention in dye formulation by neutral inorganic can make in dye bath dyestuff fiber with
Balance between water shifts to machine direction.With neutral inorganic substitute part of auxiliary (predominantly dispersant) can both reduce dyestuff into
This, can reduce quinoline, formaldehyde, the COD dyed in residual night, reduce environmental pollution again.Disperse dyes of the present invention are applied to
Polyester material and the dyeing of vinegar fiber material are contaminated, especially passes through dyes in one bath with reactive dye, direct dyes when printing and dyeing polyester-cotton fabric
Color, had not only saved accelerant but also had reduced the usage amount of dispersing aid, and two kinds of dyestuff one-bath processes realize what is promoted dye and disperse
Balance.Light color in dye is especially suitable for, coloured light, application performance are stable when contaminating shallow middle color, favorable reproducibility.
Compared with prior art, anionic auxiliary agent is replaced by using substantial amounts of inorganic salts so that the row of dyeing and printing sewage
Great reduction is put, while ensure that disperse dyes, in coloured light and the reliability and stability of tint applications aspect of performance, are so both saved
About production cost again reduces the discharge in dyeing waste-water.
