Abstract

The invention discloses an environment-friendly purple reactive dye mixture for wool. The mixture comprises the following ingredients in parts by weight: 60-90 parts of dye A, 40-60 parts of dye B and 50-80 parts of dye C. The environment-friendly purple reactive dye mixture for wool, disclosed by the invention, is high in fixation ratio and fiber dye combination stability, good in fastness, excellent in improving property, levelling property, solubility and eluting property; compared with the conventional dye, the dye disclosed by the invention consumes less inorganic salt and alkali, thereby belonging to environment-friendly dyes.

Description

technical field [0001] The invention relates to the technical field of reactive dyes, in particular to a purple reactive dye mixture for wool composed of three dyes. Background technique [0002] Now generally dyeing wool and cashmere, the dyes used are acid dyes, acid mordant dyes and metal complex dyes. Because the materials dyed with these types of dyes have poor fastness, the shade is not very bright, and it will cause troubles to the environment. In the 21st century, due to environmental and ecological constraints, the requirements for color uptake rate, color fixation rate and dyeing wastewater are getting higher and higher. Acid dyes can no longer meet the development of the times. [0003] The technical problem to be solved by the present invention is to provide a purple reactive dye for wool that can reduce environmental pollution, has low raw material cost, high product solubility, bright color, excellent application performance, convenient use and strong applica...
