Abstract

The present invention relates to a monoazo dye composition which basically comprises the following components by the weight proportion: 4 to 32% of dye monomer A, 3 to 20% 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 dispersing dye composition 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 dispersion red dye composition
(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 dye uptake height, washing fastness is good, fastness is good, heat-resisting transport property is little dispersion red dye composition, is suitable for the dyeing of multifilament combination lining such as polyester blended lining.
Dispersion red dye composition of the present invention, form by following component basically:
Weight percentage is 4~32% the dye monomer A suc as formula (I),
Figure C20041006817000031
Weight percentage is 3~20% 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.
Described auxiliary agent is one of following or its two or more mixture: naphthalene sulfonic acidformaldehyde condensation product, alkyl naphthalene sulfonic acid formaldehyde condensation products, 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), dispersing agent CNF (benzyl naphthalenesulfonate formaldehyde condensation compound) etc.; Sulfonated lignin such as sodium lignosulfonate (as commercial dispersants Reax 83A, Reax 85A) etc.
The weight percentage of described dye monomer A is preferably 5~25%, and the weight percentage of dye monomer B is preferably 5~15%.
Dispersion red dye composition 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.
Dispersion red dye composition of the present invention also can prepare by the following method:
Earlier make finished product dyestuff C, make finished product dyestuff D, will measure the finished product dyestuff C of ratio again by dye monomer B and auxiliary agent by dye monomer A and auxiliary agent) and finished product dyestuff D, auxiliary agent add water piece together mix after, grinding dispersion, spraying drying then; Also above-mentioned finished product dyestuff C, finished product dyestuff D and auxiliary agent directly can be pieced together mixedly, be ground to and be uniformly dispersed.Equally, above-mentioned dyestuff C and dyestuff D also can adopt the commercially available prod.
Dispersion red dye composition 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.
(4) embodiment
The invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this.
Embodiment 1~7
According to data shown in the table 1, after dye monomer A, dye monomer B, auxiliary agent (Dispersant MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde), dispersing agent CNF (benzyl naphthalenesulfonate formaldehyde condensation compound), dispersing agent NNO (naphthalene sulfonic acidformaldehyde condensation product), sodium lignosulfonate) added water and piece together to mix, grind dispersion with shredder, spraying drying gets final product.
