A process for improving the wet fastness properties of dyeings on synthetic polyamide fiber material is provided. The process is characterized in that preparations are applied to the fiber material at temperatures of 20 DEG to 120 DEG C, which contain a water-soluble fixing agent with affinity for the fiber, an organic solvent or solvent mixture and at most 10 percent of water, relative to the preparation, and also, optionally an organo-soluble dispersing agent. The fiber material thus treated shows very good fastness properties and no deterioration of handle. |
