The invention relates to a process for dyeing fiber materials from natural or synthetic polyamides from an aqueous liquor with dye mixtures in the presence of alkali metal or ammonium salt and, if appropriate, in the presence of auxiliaries, which is characterized in that these fiber materials are mixed with a mixture comprising at least one sulfo group-containing 1 : 1 - metal complex dye and at least one sulfo-containing metal-free dye in the presence of alkali or ammonium fluoride, alkali or ammonium fluorosilicate, alkali or ammonium fluoroborate, alkali or ammonium fluorozirconate or alkali or ammonium fluorosulfonate, at a pH of 3 to 7 colors. The process according to the invention is suitable for dyeing natural or synthetic polyamide materials, fiber and flat dyeings having good fastness properties being achieved. |
