Monoazo disperse blue dye and bi-component disperse blue dye as well as preparation method thereof

Abstract

The invention discloses a monoazo disperse blue dye and a bi-component disperse blue dye as well as a preparation method thereof. The monoazo disperse blue dye is a compound having a structural formula (I) shown in the specification. Through verification, the bi-component disperse blue dye can be applied to staining of hydrophobic fiber and blend fabric thereof such as terylene, nylon, polyurethane fiber and the like, has bright-coloured luster and is equalled to disperse blue 2BLN. Through changing the proportion of coupling components A and B in reaction raw materials, the functions of regulating the colored light of the dye and realizing synergia can be achieved so as to satisfy the requirement on different application conditions. In addition, the dye has high lifting property, favorable color fastness for washing, solarization, sublimation and the like, and has more excellent comprehensive performance than the disperse blue 2BLN. The invention has the advantages of low production cost and wide application prospect.

Description

technical field The invention belongs to the field of dye chemistry, in particular to a monoazo disperse blue dye, a two-component disperse blue dye and a preparation method thereof. Background technique Azo disperse dyes are an important class of synthetic dyes. They have complete chromatograms, a wide variety, excellent performance, simple reactions in the synthesis and preparation process, variable structures, and low cost. They are widely used in the printing and dyeing industry. Among them, the blue variety is used the most, but due to its lack of blue with excellent performance, it has been unable to replace the more expensive anthraquinone disperse blue dye 2BLN; in addition, the utilization rate and economic benefits of colors and dyes in the printing and dyeing industry The requirements are constantly increasing, so the development of a blue disperse dye with excellent performance, good promotion, adjustable shade, high quality and low price is an urgent problem in ...

AI Technical Summary

Problems solved by technology

Therefore, the technical problem to be solved in the present invention is to provide a kind of azo disperse blue dye for the existing azo disperse blue dye with dark color, low brilliance and poor performance. Vibrant, adjustable shade, with excellent lift and color fastness
