Problems solved by technology

If a chloro-s-triazine is replaced by a medium-temperature-type fluoro-s-triazine reactive group, although the activity of the vinyl sulfone reactive group can be consistent and the coloring rate can be increased, the production cost of trifluoro-s-triazine (trifluoro triazine) is too high. High, the economic benefits of dye products are low

Abstract

The present invention is a reactive dye of the following formula (I) with the sulfur alkyl-s-triazoxide base; therein, the definitions of A, X, Y, Z, R, Q, as well as (a) are as shown in the patent specification. The reactive dye of the present invention can be used in the medium-temperature dip-dye, cool dye and continuous dye of the fiber containing the hydroxyand nitrogen.

Description

technical field [0001] The present invention relates to a novel reactive dye, especially a reactive dye with sulfanyl-s-triazoxide. Background technique [0002] Reactive dye technology with alkylthio-s-triazine single reactive groups was developed from the 1960s to the early 1980s. It is mainly the technology of thio / sulfur single reactive group reactive dyes with -s-triazine (s-triazine) or pyrimidine derivatives (pyramine), as disclosed in British Patent GB923068. [0003] Although there was research and development of reactive dyes from 1986 to 1996, the research and development of reactive dyes was limited to specific dye chromophores, as disclosed in European Patent EP0264878 and Japanese Patent JP10-001618. Reactive dyes with monochlorotriazine and vinylsulfone as dual reactive groups are the mainstream of the 60°C medium-temperature reactive dyes market today, but due to the great difference in the reactivity of the two reactive groups, In dyeing application, the v...
