Black Dye Mixtures of Fiber-Reactive Azo Dyes and Use Thereof for Dyeing Hydroxy- and/or Carboxamido-containing Fiber Material

摘要

The invention ; Coupling (coupling) as a component 1-amino-8-naphthol-3,6-sulfonate, and vinyl sulfone series of fiber-reactive groups different 1 2 or more disks composed of diazo components of the aniline series of azo, each comprising dyes; ; A coupling component as a sulfo-substituted 2-amino-naphthalene, and vinyl sulfone series of fiber-reactive monoazo dye of at least one consisting of a diazo component of the aniline series containing group; And ; Alternatively, as a coupling component 1-amino-3,6-sulfo-8-naphthol have the fibers of the vinyl sulfone series - a diazo component of the aniline series substituted by a reactive amino groups ortho to the coupling component - the coupling in the position one or two monoazo dyes ; It relates to a dye mixture comprising a. The dye mixtures of the invention are cellulose fibers, in particular hydroxyl, such as cotton-containing fiber material is dyed with dark color-containing fiber materials, and / or wool and synthetic polyamide fibers, such as carboxamido.
