Problems solved by technology

[0003] The printing process has high requirements on dyes. Firstly, reactive dyes are required to have high solubility and dissolution speed. Secondly, dyes are required to have good compatibility and level dyeing, no color difference and white cloth staining problems; resist printing It is a special process of printing. At present, there is no brilliant blue or emerald blue (phthalocyanine) reactive dyes used in this process, and the commercially available phthalocyanine dyes used in the resist printing process are not reactive dyes. When adding volatile anti-dyeing agents, it will cause great pollution to the environment and affect the health of workers, and it is easy to produce overlapping patterns when color matching with other dyes, or there are defects in the process, which increases the difficulty of the printing process
[0004] At present, reactive blue 14 and blue 49 are commonly used in the market, and they are basically not used in the resist printing process. This is mainly because of their large molecular structure and good molecular planarity, which leads to their great directness to fibers, making dyes The color fastness to staining is very poor, and the phenomenon of taking flowers is serious

Abstract

The invention discloses a cobalt blue active dye mixture which is formed by splicing and mixing compounds shown in a structural formula (I), a structural formula (II) and / or a structural formula (III). The cobalt blue active dye mixture comprises the compounds in percentage by mass: 50-70% of the compound shown in the structural formula (I), 0-50% of the compound shown in the structural formula (II) and 0-50% of the compound shown in the structural formula (III). 65-80% of the cobalt blue active dye mixture, 5-10% of a diffuser, 0.1-0.5% of a dust preventive, 5-15% of anhydrous sodium sulphate and 5-10% of a nonionic levelling agent are mixed to prepare a commercial dye. The commercial dye is used for preventing dyeing and printing for cellulose fiber fabrics and has the advantages of bright in color and luster, no phenomenon of kiss spot of leather, high staining fastness of white cloth and clean and environmental-friendly printing process.

Description

technical field [0001] The invention relates to the field of reactive dyes, in particular to a brilliant blue reactive dye composed of two-component or three-component compounds and the application of the dye mixture in resist printing on cellulose fiber fabrics. Background technique [0002] Reactive dyes have developed rapidly due to their advantages such as complete chromatograms, bright colors, excellent performance, and strong applicability. Due to the increasingly stringent environmental protection in my country, energy-saving, emission-reducing, and environmentally friendly green processes are vigorously advocated. For reactive dyes, the amount of wastewater produced by different dyeing processes and the COD in wastewater are very different. For exhaust dyeing, due to the liquor ratio requirements, this dyeing process will produce a large amount of wastewater, and the dyeing process of exhaust dyeing The utilization rate of the dye is not high (generally, the fixation...
