Composite disperse golden yellow dye with high washing fastness and high dyeing rate

Abstract

The invention discloses composite disperse golden yellow dye with high washing fastness and high dyeing rate. The composite disperse golden yellow dye with high washing fastness and high dyeing rate is prepared from the following ingredient in percentage by weight through mixing: 1 to 80 percent of dye A, 1 to 80 percent of dye B and the balance of auxiliary agents. When the composite disperse golden yellow dye provided by the invention is used for superfine polyester fiber dyeing, the performance such as the washing fastness and the dyeing rate is prominent; the performance such as crockfastness is also better. The composite disperse golden yellow dye with high washing fastness and high dyeing rate is provided for the dyeing of fiber such as terylene; the dyeing quality of the fiber products such as terylene is well improved.

Description

Technical field [0001] The invention relates to the technical field of disperse dyes, in particular to a composite disperse golden dye with high washing fastness and high coloring. Background technique [0002] In recent years, due to the extremely fine diameter and large surface area of ​​polyester or blended fabrics, its fabrics have the characteristics of high coverage, soft hand feeling and comfortable wearing, etc., which have become more and more widely used and have become domestic and foreign textile enterprises. Textile raw materials competing to use. Due to the structural characteristics of polyester, high-temperature dyeing is limited, and low-temperature dyeing often prevents disperse dyes from dyeing the polyester well. During the dyeing process, some dyes cannot enter the interior of the fabric and can only be absorbed on the surface to form floating colors. These floating dyes seriously affect the washing fastness of the fabric. The floating color of the fabric is...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of low coloring rate and poor washing fastness of the composite disperse dyes in the prior art, and provide a high washing fastness and high coloring composite disperse golden dye, which has high washing fastness and high coloring composite When the disperse golden dye is used in the dyeing of polyester or blended fabrics, the dyeing rate is high and the color fastness is good, which can well improve the dyeing quality of polyester or blended fabrics
