Problems solved by technology

However, with the textiles dyed with C.I. Disperse Orange 30 dyes, the detection of pentachlorophenol and allergenic dyes seriously exceeds the standard, and its alkali resistance is poor, and the shade turns red when dyed in a medium above pH7.0. Therefore, the dyeing process is complex and Shade instability of textiles

Abstract

The invention relates to an environment-friendly alkaline-resistant high-washing-dispersity orange dye composition and an application thereof. The dye composition comprises dyes and auxiliaries, wherein the dyes include a dye A and a dye B; the structural formula of the dye A is as shown in the specification, while the structural formula of the dye B is as shown in the specification; the environment-friendly alkaline-resistant high-washing-dispersity orange dye composition is applied to textile dyeing. The environment-friendly alkaline-resistant high-washing-dispersity orange dye composition is good in all build-up, fixation rate, levelling property, compatibility and alkali resistance, and especially quite excellent in washing fastness. Specially, the dye composition is similar to the existing C.I. disperse orange 30 dye in chromatic light intensity and dyeing property, overcomes the defects of no resistance to alkali and non-environmental friendliness of the existing dye, and thus can be used for substituting for the existing C.I. disperse orange 30 dye.

Description

technical field [0001] The invention belongs to the field of dyeing compositions and applications thereof, in particular to an environment-friendly alkali-resistant high-washing disperse orange dye composition and applications thereof. Background technique [0002] With the continuous development of industrial production, energy consumption is becoming more and more serious, and energy conservation and environmental protection are becoming more and more important. Therefore, like the printing and dyeing industry, higher requirements are put forward for the environmental protection, energy saving performance and dyeing performance of dyes. [0003] C.I. Disperse Orange 30 is a brownish-red powdery solid. This dye is used in a large amount. As one of the basic medium-dark matching colors, it can match colors with Disperse Red 2GFL and Disperse Blue BGL. Good strength and fastness. However, with the textiles dyed with C.I. Disperse Orange 30 dyes, the detection of pentachloro...
