Problems solved by technology

However, the residual liquid of disperse dyes in the dyeing process is deep and the pollution is large.
The dyed fur is sensitizing to the human body. As the country’s pollution requirements for the fur printing and dyeing industry are getting higher and higher and consumers’ safety requirements for fur products are increasing, the original disperse grass dyes can no longer meet the industry requirements. The industry needs a new dye to meet the national environmental protection requirements

Abstract

The invention provides an acidic dischargeable blue dye compound for furs and a synthesis and application method of the acidic dischargeable blue dye compound for the furs. A molecular formula of the acidic dischargeable blue dye compound for the furs is C13H15O5N5S2, and an acidic dischargeable blue dye is a monoazo acidic dye. The acidic dischargeable blue dye compound for the furs has a small relative molecular mass being 386 and is quite suitable for dyeing of the furs. The method is convenient and simple in operation, easy in condition control and low in operation cost. The acidic dischargeable blue dye compound synthesized according to the method has the advantages of freeness of 24 forbidden aromatic amine structures and allergenicity, high color saturation, excellent color fastness performances, superior compatibility, high dye-uptake and absorption rate, less dyeing residues and low influences on environment, thereby being an environment-friendly product and pretty suitable for serving as the dischargeable blue dye and enriching designs and colors in the field of fur dyeing.

Description

technical field [0001] The invention relates to the technical field of animal fur treatment, in particular to an acidic pullable blue dye compound for fur and its synthesis and application method. Background technique [0002] Since the reform and opening up, China's economy has made great progress. The economic aggregate has grown exponentially, rapidly surpassing many developed countries, and people's living standards have improved greatly. However, it took China 30 years to complete the road that many developed countries took hundreds of years to complete. This is a miracle of economic development, but it has also brought great damage to people's living environment. This brutal and savage economic growth method eventually brought us all kinds of water, air, soil and other environmental pollution. The city's smog shrouded the sky every day, and people could only live in a blurry world. [0003] The fur industry is also a traditional industry with a lot of pollution. In or...
