Problems solved by technology

[0004] However, for textiles dyed with C.I. Disperse Orange 30 dyes, the detection of pentachlorophenol and allergenic dyes seriously exceeds the standard. At the same time, its alkali resistance is poor, and the shade turns red when dyed in a medium above pH 7, resulting in unstable shade of the textile.

Abstract

The invention relates to a mixture of environment-friendly and alkali resistant type dispersed orange dye, comprising dye and addition agent, which is characterized in that the dye part comprises the following three dyes: dye agreed with the general chemical formula (I), the weight of which is 2.5 to 95 percent of the gross weight of the dye part, wherein, the R in the formula is hydrogen group, alkyl or phenyl; dye agreed with the general chemical formula (II), the weight of which is 2.5 to 95 percent of the gross weight of the dye part; and dye agreed with the general chemical formula (III), the weight of which is 2.5 to 95 percent of the gross weight of the dye part. The mixture of environment-friendly and alkali resistant type dispersed orange dye is similar to the current C.I. dispersed orange 30 dye in color light strength and dyeing property but overcomes the drawbacks of the current dye of poor alkali resistance and poor environment protection, so can replace the current C.I. dispersed orange 30 dye.

Description

technical field [0001] The invention relates to a disperse orange dye mixture, in particular to an environment-friendly and alkali-resistant disperse orange dye mixture suitable for polyester fiber or fabric dyeing or printing. Background technique [0002] Disperse dyes are a kind of non-ionic dyes that use dispersants to make dye particles in a dispersed state in the initial stage of the dyeing process. Disperse dyes have a complete chromatogram, bright dyeing color, high color strength, good color fastness, easy manufacture and good economy. According to the statistics of China Dyestuff Industry Association, the use of disperse dyes in my country ranks first in the dye consumption. [0003] The International Dyestuff Index number is C.I. Disperse Orange 30 is a brownish-red powdery solid. This kind of dye is used in a very large amount in China every day. It can be used as one of the basic medium and deep matching colors. It can be used with Disperse Ruby 2GFL and Dispers...
