Problems solved by technology

[0002] In cotton fiber dyeing, black accounts for almost 40-50%, and the more direct dyes and sulfur dyes used are prohibited and restricted due to environmental protection issues.
The comprehensive effect of the reactive black dye composition of prior art such as CN104804470A is difficult to reach people's expectation, needs further improvement and enhancement, as there are defects in dyeing reproducibility and various color fastness

Description

technical field [0001] The invention relates to a black reactive dye composition and its preparation method and application. Background technique [0002] In cotton fiber dyeing, black accounts for almost 40-50%, and more direct dyes and sulfur dyes are banned and restricted due to environmental protection issues. The comprehensive effect of the reactive black dye composition of the prior art such as CN104804470A is difficult to reach people's expectations, and needs further improvement and improvement, such as defects in dyeing reproducibility and various color fastnesses. Contents of the invention [0003] The invention provides a black reactive dye composition, which has the advantages of good dyeing reproducibility, high cost performance, high relative color fixation rate, good color fastness to friction, water washing and perspiration, and the like. In addition, the invention also provides a preparation method of the composition. [0004] The invention provides a bl...
