ABSTRACT:
A process for the treatment of textiles in rope form with gaseous and/or liquid treating agents in a jet dyeing unit, wherein the charging of the jet apparatus with the material rope as well as the material transport in the unit is effected by directing a gas current, especially steam, issuing from nozzles under excess pressure onto the fibrous material. To start the process, the gas current and the fluid current may be used alternately or may be combined. The process is particularly suitable for the isothermal dyeing of textiles in rope form with heat-fixable dyestuffs in accordance with the batchwise exhaustion method.
