Abstract

The invention discloses a compound discharge printing disperse dye, which comprises the following components in percentage by weight: 1-25% of a dye monomer shown in a formula (I); 5-40% of a dye monomer (2) shown as a formula (II); 1-15% of a dye monomer (3) shown as a formula (III); 0-10% of a dye monomer (4) shown as a formula (IV); the balance of auxiliary agent. The compound discharge printing disperse dye is very suitable for printing and dyeing polyester fibers, silk-like fabrics, suede and corduroy. As a discharge ground color dye, the dye has high whiteness and reductive discharge property, has more colorful, fine and clear pattern printing effects, and can be used for local printing and light color printing on dark color fabrics. The compound discharge printing disperse dye has perfect compatibility, and has the advantages of good reproducibility, small heat migration resistance and the like during printing and dyeing.

Description

A kind of composite discharge printing dispersion dyes

Technical field

The present invention relates to a kind of dyestuff, especially a kind of by the composite discharge printing dispersion dyes that forms of dispersed dye.

Technical background

Along with improving constantly that style requires, the contour sharpness of direct printing, decorative pattern fineness all are subjected to certain restriction, and discharging dye just in time solves this difficult problem.The decorative pattern printing effect of this discharging dye is more much better than direct printing, particularly can print light decorative pattern, pattern on deep-colour fabric, more can be on silk-like fabric discharge printing.

But compatibleness is bad between existing each component of composite dye ubiquity that can be used for discharge printing mostly because in the discharge printing process compatibleness between each component of composite dye is required outstanding high, otherwise the circulation ratio that is difficult to reach good and dawn degree.

Summary of the invention

It is good to the invention provides a kind of compatibleness, have good circulation ratio and dawn degree the Compositional type discharge printing dispersion dyes.

A kind of Compositional type discharge printing dispersion dyes, weight percent consists of:

1～25% suc as formula the dye monomer (1) shown in (I);

5～40% suc as formula the dye monomer (2) shown in (II);

1～15% suc as formula the dye monomer (3) shown in (III);

0～10% suc as formula the dye monomer (4) shown in (IV);

Surplus is an auxiliary agent.

In the Compositional type discharge printing dispersion dyes of the present invention, dye monomer (4) is optional component;
