ABSTRACT:
A steam lock is connected to the processing chamber in which textile goods are treated with an organic solvent which is immiscible with water. The web of material is led through this lock. This steam lock consists of an evacuation chamber which is separated from the processing chamber by a pair of sealing lips, of a plurality of steam chambers which are separated from each other and from the evacuation chamber by constrictions, and of a compensating chamber which is also separated by a constriction from the steam chambers. All the chambers are connected to a condenser and a water separator by means of a suction duct. The steam chambers are equipped with steam pipes which are adjustable and provided with slit nozzles, and superheated steam is supplied to these steam pipes.
