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

摘要

Process for dyeing synthetic polyamide materials withfibre-reactive anthraquinone dyesAbstractProcess for preparing ozone-fast dyeings onsynthetic polyamide fibre materials from aqueous liquorwith anthraquinone dyes which comprises using at least oneanthraquinone dye which contains one or two fibre-reactivegroups and one or two sulfo groups.The process according to the invention is suitablefor dyeing synthetic polyamide materials producing withthe monosulfoanthraquinone or disulfoanthraquinone dyeswhich contain one or two fibre-reactive groups level dye-ings having good fastness properties, in particular goodozone fastness.
