Abstract
The present disclosure relates to a process for the continuous pad-dyeing or printing of continuous synthetic filament groups with dyestuffs which are set under the influence of heat. More particularly, the present disclosure is directed to a process for the continuous pad-dyeing of synthetic filament groups wherein a heated treatment medium, for example air, is passed through the filament groups which have been printed or padded with the preparations containing the dyestuffs. By drawing heated air through the material being treated a completely uniform drying of the filament groups and also a uniform dyestuff setting is obtained and a migration of the dyestuffs is substantially avoided.
