Problems solved by technology

[0004] Existing patent: CN99104177.1 Disadvantage: light fastness is not high
For example, the right-side benzene ring (diazo component) in structure (E) and structure (F) has insufficient electron-absorbing ability, resulting in a decrease in the light fastness of the dye
As a compound dye, as long as the light fastness of a certain component is poor, it is easy to fade due to the sun during use, which will cause the color of the entire fabric to change, and eventually cause the entire light fastness to decline in an all-round way.

Abstract

The invention relates to the printing and dyeing industry, and in particular relates to a dispersed azo dye composition, a preparation method and dyeing application of the dispersed azo dye composition in hydrophobic fibers. The dispersed azo dye composition comprises one or more than one of organ dye components A shown in a formula (I), one or more than one of blue dye components B shown in a formula (II), one or more than one of purple dye components C shown in a formula (III) and one or more than one of yellow dye components D shown in a formula (IV). In addition, the invention further provides a dye product produced form the dispersed azo dye composition, a preparation method and application of the dye product. The dispersed azo dye composition provided by the invention has excellent light fastness, and the dye product prepared from the dispersed azo dye composition provided by the invention has excellent light fastness.

Description

technical field [0001] The invention belongs to the printing and dyeing industry, and specifically relates to a disperse azo dye composition, a preparation method thereof, and a dyeing application for hydrophobic fibers. Background technique [0002] Disperse dyes are a class of non-ionic dyes mainly used for dyeing hydrophobic fibers. Due to the combination of disperse dyes and fibers only by weak van der Waals force, it usually leads to poor sublimation resistance, sunlight and heat migration fastness of disperse dyes on fibers. Unlike natural fibers such as cotton, hemp, and silk, hydrophobic fibers are mainly used in special fields such as outdoor products, automotive interior materials, sails, and cables. Therefore, the disperse dyes used in this series of fiber dyeing have very high requirements for light fastness. [0003] The mechanism of fading (poor light fastness) of azo disperse dyes during use is that the dyes first produce azo oxide compounds under the action...
