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.
Claims10
A system for recovering the residues of solvents which remain in textile material during continuous processing of the textile in a processing chamber with a solvent which is organic and immiscible with water, or with a processing medium which contains same, followed by driving off of the solvent from the textile material being processed by means of a gas which is heated above the boiling temperature of the solvent and condensation of the gas containing the solvent,
- said system comprising a chamber arrangement connected in gas-tight manner to the processing chamber and including at least three chambers equipped with transport means for the textile and separated by locks from each other,
- at least one of said chambers which is neither the first nor the last chamber traversed by the textile is provided with nozzle means for propelling heated gas through the textile, and
- at least the first traversed chamber being provided with means for evacuating said first traversed chamber.

- said system comprising a chamber arrangement connected in gas-tight manner to the processing chamber and including at least three chambers equipped with transport means for the textile and separated by locks from each other,
- at least one of said chambers which is neither the first nor the last chamber traversed by the textile is provided with nozzle means comprised of pipes having at least one slit extending in their lengthwise direction for propelling heated gas through the textile, said nozzle means mounted for adjusting the spacing between said nozzle means and said textile material, and
- at least the first traversed chamber being provided with means for evacuating said first traversed chamber.
