ABSTRACT:
The invention describes a process for the discontinuous aftertreatment of synthetic hydrophobic textile material, especially polyamide or polyester textile material, which is dyed preferably from an organic liquor with disperse dyestuffs containing hydroxyl and/or amino groups, with chemical fixing agents such as isocyanates, masked isocyanates, acid halides or acid anhydrides, from chlorinated aliphatic hydrocarbons, especially perchloroethylene, at temperatures above 80.degree.C, and subsequently rinsing and drying this material on which dyeings are obtained that are fast to water, solvents, light and are also very fast to sublimation.
