Abstract

The present invention relates to a monoazo dye composition which basically comprises the following components by the weight proportion: 10 to 35% of dye monomer A, 1 to 15% of dye monomer B and an auxiliary agent as the rest, wherein the dye monomer A is represented by a formula (I); the dye monomer B is represented by a formula (II). The composite dispersing red dye is particularly suitable for dyeing polyester material and yarn and printing and has the advantages of outstanding coloring performance by hot melting at high temperature, good fastness, such as light fastness, sublimation fastness and washing fastness.

Description

A kind of composite disperse red dye
(1) technical field
The present invention relates to a kind of Monoazo-dyes composition.
(2) background technology
From the weaving face fabric present situation, the shared ratio of lining that is formed by multiple fiber combinations increases year by year, and some the medium-to-high grade linings as domestic comprise polyester blended lining etc.Gong Ying dispersed dye in the market, can't satisfy the printing and dyeing needs of such textiles well: its thermophoresis fastness and water washing fastness are all not ideal enough, have influenced the various wet fastness of dope dyeing, have also brought the pollution to surrounding environment.
(3) summary of the invention
For overcoming the deficiency of existing dispersed dye, the object of the invention is to provide a kind of composite disperse red dye of excellent property, is suitable for multifilament combination lining such as polyester blended and the dyeing of expecting.
Composite disperse red dye of the present invention, form by following component basically:
Weight fraction is 10~35% the dye monomer A suc as formula (I),
Weight fraction is 1~15% the dye monomer B suc as formula (II),
Surplus is an auxiliary agent.
Because the singularity of dye industry is difficult to also there is no need to make pure product, can have the impurity in some preparation process usually, also allows to contain the physics impurity of a spot of moisture content and trace when composite disperse orange dye of the present invention is made finished product.
The weight fraction of described dye monomer A is preferably 15~30%, and the weight fraction of dye monomer B is preferably 1~10%.
Described auxiliary agent can be one of following or its mixture: naphthalene sulfonic acidformaldehyde condensation product, alkyl naphthalene sulfonic acid formaldehyde condensation products, benzyl naphthalenesulfonate formaldehyde condensation compound, sulfonated lignin.Described naphthalene sulfonic acidformaldehyde condensation product such as dispersing agent NNO; Alkyl naphthalene sulfonic acid formaldehyde condensation products such as Dispersant MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde) etc.; Benzyl naphthalenesulfonate formaldehyde condensation compound such as dispersing agent CNF; Sulfonated lignin such as sodium lignosulfonate (as commercial dispersants Reax 83A, Reax 85A) etc.
Composite disperse red dye of the present invention can prepare by the following method:
After dye monomer A, dye monomer B, auxiliary agent, water or the mixing of other wetting agent with the metering ratio, grind dispersion with shredder, then spraying drying.Above-mentioned dye monomer A and monomers B can adopt the commercially available prod respectively, as the former dyestuff of Disperse Red TRHNF and the C.I. DISPERSE ORANGE 30 200 73 former dyestuffs of Zhejiang Province Longsheng Group Co., Ltd's production.
Composite disperse red dye of the present invention also can prepare by the following method:
Earlier make finished product dispersive red dye C by dye monomer A and auxiliary agent, will measure again the finished product dispersive red dye C of ratio and C.I. DISPERSE ORANGE 30 200 73 (main ingredient is dye monomer B and auxiliary agent), auxiliary agent add water piece together mix after, grind dispersion, then spraying drying; Also this finished product dispersive red dye C, C.I. DISPERSE ORANGE 30 200 73 and auxiliary agent directly can be pieced together mixedly, be ground to and be uniformly dispersed.Equally, above-mentioned finished product dispersive red dye C and C.I. DISPERSE ORANGE 30 200 73 also can adopt the commercially available prod, as the Disperse Red TRHNF and the C.I. DISPERSE ORANGE 30 200 73 of Zhejiang Province Longsheng Group Co., Ltd's production.
Composite disperse red dye of the present invention is very suitable for dying polyester material, yarn dyeing and stamp, and high temperature hot melt dyeing behavior is splendid, and the fastness excellent property is all good as sun-resistant fastness, fastness to sublimation, wash resistant fastness.
