Abstract

The invention provides a red reactive dye compound, as well as a synthesis method and applications thereof. The reactive dye compound is selected from dyes represented by the general formula (1) in the specification. The red reactive dye compound is bright in color and has excellent dyefastness in various aspects. The red reactive dye compound has good compatibility with other reactive dyes. The red reactive dye compound is suitable for dye applications in cellulose fiber, wool, true silk and blended products thereof.

Description

technical field [0001] The invention relates to a new kind of reactive dye and its dyeing application on fiber materials. Specifically, the invention relates to a kind of red reactive dye and its dyeing application on fiber materials. Background technique [0002] One of the varieties widely used in the current red reactive dye species is C.I. reactive red 195, whose structural formula is: [0003] [0004] This dye compound has a relatively bright hue and good color fastness, but it also has certain defects, and it is difficult to meet the current printing and dyeing needs, and needs to be further improved. [0005] Since the dye came out in 1982, major companies in the world have successively published numerous patents through experimental research to improve and perfect the structure of C.I. [0006] These patents are: [0007] JP 59136353 (1984) (Mitsubishi Chemical) [0008] JP 63128079 (1988) (Sumitomo) [0009] US 4378313 (1983) (Sumitomo) [0010] US 5324329...
