PROCESS FOR DYEING SYNTHETIC POLYAMIDE MATERIALS WITH FIBRE-REACTIVE ANTHRAQUINONE DYES

摘要

Process for dyeing synthetic polyamide materials with fibre-reactive anthraquinone dyes Process for preparing ozone-fast dyeings on synthetic polyamide fibre materials from aqueous liquor with anthraquinone dyes which comprises using at least one anthraquinone dye which contains one or two fibre-reactive groups and one or two sulfo groups. The process according to the invention is suitable for dyeing synthetic polyamide materials producing with the monosulfoanthraquinone or disulfoanthraquinone dyes which contain one or two fibre-reactive groups level dyeings having good fastness properties, in particular good ozone fastness.
