Abstract
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°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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
109 words
A process for dyeing synthetic hydrophobic textile material, which comprises dyeing the textile material with a disperse dyestuff containing a hydroxyl and/or a primary or secondary amino group and thereafter treating, at a temperature above 80°C, the dyed textile with a solution of a fixing agent in a chlorinated aliphatic hydrocarbon boiling above about 100°C, the fixing agent consisting essentially of an acylating agent selected from the group consisting of organic isocyanates, masked organic isocyanates, aliphatic monocarboxylic acid halides of at least 8 carbon atoms, aromatic carboxylic acid halides, heterocyclic carboxylic acid halides, aliphatic dicarboxylic acid halides, aliphatic polycarboxylic acid halides, and aliphatic and aromatic cyclic dicarboxylic acid anhydrides.
Claim 2
