Disperse orange dye mixture

Abstract

Disclosed is a dispersed orange dye mixture, composed of two parts, a dye and an auxiliary, and characterized in that the dye part is at least composed of the dyes of the following three structures: the first one being a dye corresponding to the chemical structural formula (I), and having a content of 2-80% of the total weight of the dye part; the second one being a dye corresponding to the chemical structural formula (II), and having a content of 2-80% of the total weight of the dye part; and the third one being a dye corresponding to the chemical structural formula (III), and having a content of 2-80% of the total weight of the dye part.

Description

technical field [0001] The invention relates to a disperse dye suitable for dyeing polyester fibers or fabrics, in particular to an environment-friendly disperse orange dye mixture with good alkali resistance and low price. Background technique [0002] Disperse dyes are a kind of non-ionic dyes that dye hydrophobic fibers in a dispersed state under the action of dispersants in the initial stage of the dyeing process. Disperse dyes have a complete color spectrum, bright color, high color strength and good economy. According to the statistics of China Dyestuff Industry Association, the consumption of disperse dyes in my country ranks first among all kinds of dyes, and 60% of the disperse dyes used in the world are produced and exported from my country. [0003] Among the commonly used orange disperse dyes in the past, the International Dyestuff Index numbers are C.I. Disperse Orange 1, C.I. Disperse Orange 3, C.I. Disperse Orange 37, C.I. Disperse Orange 76, C.I. Disperse Or...

AI Technical Summary

Problems solved by technology

If C.I. Disperse Orange 1, C.I. Disperse Orange 3, C.I. Disperse Orange 37, C.I. Disperse Orange 76 and C.I. Disperse Orange 61 are still used in disperse dyes, it will lead to detectable allergenic dyes and bromine in dyed textiles Elements seriously exceeded

If you still use C.I. Disperse Orange 29, C.I. Disperse Orange 30, C.I. Disperse Orange 41, C.I. Disperse Orange 62, C.I. Disperse Orange 73 in disperse dyes, it will lead to detectable dichlorophenol and trichlorophenol in dyed textiles. Organochlorine compounds such as tetrachlorophenol and pentachlorophenol seriously exceed the standard, and the alkali resistance is poor. When dyeing in a medium with a pH above 7, the color light turns red, causing the color cast of the textile (lack of yellow light)

It can be seen that in order to overcome the deficiencies in the prior art and meet the needs of domestic and foreign markets, the currently used disperse orange dyes need to be further upgraded.
