Problems solved by technology

[0003] However, there are some problems in the disperse dyes for direct printing of polyester fibers on the market at present, such as too much color difference under various light sources, not bright enough color, and the light fastness, washing, sublimation and perspiration fastness of the dyes are not enough. Therefore, the market urgently needs High fastness disperse dyes for polyester fiber direct printing to meet increasing customer requirements

Abstract

The invention relates to a compound disperse blue dye for direct printing, comprising the following components by weight: 30-82% of dye monomer A, 10-50% of dye monomer B, 1-22% of dye monomer C and the balance auxiliary agent. The dye can be applied to directly printing pure polyester fiber fabrics or other blend fabrics and ensure the fabrics to have bright-colored, full and layered hues, has low sensitivity to change of direct printing process parameters, has good printing levelling property and high color yield percentage and can obtain optimal color fastness and simultaneously reduce COD discharge value of printing and dyeing wastewater and environmental pollution.

Description

technical field [0001] The invention relates to a blue disperse dye, in particular to a compound type direct printing blue disperse dye (disperse blue P-R) which can be used for polyester fibers. Background technique [0002] In recent years, with the development of high-performance printing machines, the maturity of printing technology, the invention of differentiated fibers, and the unique plumpness and layered nature of direct printing products, polyester fiber direct printing products have become more and more popular. It has increasingly become a high value-added product. [0003] However, there are some problems in the disperse dyes for direct printing of polyester fibers on the market at present, such as too much color difference under various light sources, not bright enough color, and the light fastness, washing, sublimation and perspiration fastness of the dyes are not enough. Therefore, the market urgently needs High fastness disperse dye products for polyester f...
