Abstract

The invention relates to a disperse red dye composition, which contains a dye A shown as a formula and a dye B shown as a formula (II); when the disperse red dye composition is used for dyeing hydrophobic fiber materials, particularly polyester materials and polyamide fiber materials, the disperse red dye composition has the characteristics of high dye uptake, excellent dyeing fastness, good lifting property, good leveling property and the like, and is also very suitable for dyeing superfine polyester fiber materials.

Description

A kind of dispersion red dye composition
(1) technical field
The present invention relates to a kind of disperse dye composition, relate in particular to a kind of painted dispersion red dye composition of hydrophobic fiber material that is applied to.
(2) background technology
As everyone knows, azo disperse dye can be used for the dyeing of synthetic or semi-synthetic hydrophobic fiber material.But along with the development of new synthon, polyester superfine fibre weaving face fabric, these dyestuffs can't satisfy higher dyeing demand, especially show dye uptake, heat-resisting migration fastness, color fastness to water, colour fastness to light, equalization aspect.For this reason, develop the heat subject that bright-coloured dyestuff of a class dyeing behavior excellence, coloured light or dye composite have become dyestuff circle.
(3) summary of the invention
In order to overcome the deficiency of existing dispersive red dye dyeing behavior, the invention provides a kind of dispersion red dye composition.
Described dispersion red dye composition contains suc as formula the dyestuff A shown in (I) with suc as formula the dyestuff B shown in (II);
Wherein, X 1For H or-CN, be preferably-CN; X 2For H ,-CN or-NO 2, be preferably H;
R 1Be H or halogen, be preferably H or chlorine;
R 2For-CH 3,-NHCOCH 3Or-NHCOC 2H 5, be preferably-NHCOCH 3
R 3, R 4Independently be-CH separately 3Or-C 2H 5, be preferably-CH 3
R 5For H or-CH 3, be preferably H;
R 6For-OC 3H 7Or-OCH 2COOC 2H 4OCH 3, be preferably-OC 3H 7
Described dye composite is preferably as shown in the formula (III) especially and the composition of two kinds of dyestuffs of structure (IV) (is X 1For-CN, X 2Be H, R 1Be H, R 2For-NHCOCH 3, R 3, R 4Be respectively-CH 3, R 5Be H, R 6For-OC 3H 7):
Based on dyestuff A and dyestuff B, the weight percentage of described dyestuff A is 60~96%, is preferably 70~95%, most preferably is 80~95%; The weight percentage of dyestuff B is 4~40%, is preferably 5~30%, most preferably is 5~20%.
When preparing dispersion red dye composition of the present invention, employed dyestuff A and dyestuff B are respectively disclosed dyestuff such as patent EP555179 and patent EP146269 or similar these dyestuff, with the method for wherein record or similarly method can make at an easy rate.
When using dispersion red dye composition of the present invention preparation dispersed dye, generally need to add auxiliary agent and disperse.For example that structural formula (I) and structural formula (II) is represented former dyestuff carries out corpusculed with pulverizers such as sand mill or shredders after mixing by above-mentioned proportioning in the presence of auxiliary agent, water or other wetting agent; Also structural formula (I) and the represented former dyestuff of structural formula (II) can be carried out mixing with above-mentioned ratio after corpusculed is handled with pulverizers such as sand mill or shredders respectively in the presence of auxiliary agent, water or other wetting agent in addition.Usually, auxiliary agent is 1~5: 1 with the ratio of former dyestuff weight.
Described auxiliary agent is dyestuff dispersion agent commonly used, diffusant etc. when composite, comprise one of following or its several mixture arbitrarily: anionic dispersing agents such as the formaldehyde condensation products of the formaldehyde condensation products of naphthene sulfonic acid and alkyl benzene sulphonate (ABS), the formaldehyde condensation products of alkyl naphthalene sulfonic acid, benzyl naphthalenesulfonate formaldehyde condensation compound, cresol sulfonic acid, sulfonated lignin, the perhaps non-ionic dispersing agents such as ethylene oxide adduct of the ethylene oxide adduct of the segmented copolymer of oxyethane, propylene oxide, alkylphenol, polystyrene phenol.Particularly, 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), benzyl naphthalenesulfonate formaldehyde condensation compound such as dispersing agent CNF etc., sulfonated lignin such as sodium lignosulfonate (as commercial dispersants Reax 83A, Reax 85A) etc.
Use the dispersed dye of dispersion red dye composition of the present invention preparation, the liquid state after can corpusculed, emulsifiable paste attitude or with spray-drying process etc. carry out dried powdery, graininess is supplied with dyeing.The dispersed dye that are mixed with dispersion red dye composition of the present invention dye hydrophobic fiber material, particularly when polyester material, polyamide fiber material, characteristics such as have dye uptake height, dyefastness excellence, enhancing is good, equalization is good also are fit to dye the hyperfine polyester fiber material very much.
