Apparatus for low liquor ratio wet processing of textile fabric

In apparatus for low liquor ratio wet processing of textile fabric in endless loop form while recirculating the fabric loop through a processing system including a vessel arranged for transiently storing a major portion of said fabric loop and a superstructure for said vessel disposed and equipped for progressively withdrawing the fabric loop from and returning it to the vessel storage to effect said fabric recirculation, the improvement with comprises a lifter roll and selectively operable aspirating means housed in said superstructue and to cause recirculating travel of the fabric loop, a foam generator mounted on said vessel, means for applying a low liquor ratio foaming formulation of the processing liquor externally to said recirculating fabric in a non-persistently foamed condition by feeding processing liquor under pressure selectively to either or both of said aspirating means and said foam generator adjacent the point of fabric return to said vessel storage so that the foamed processing liquor tends to decay to liquid phase in the course of migratory saturation of the stored fabric portion as it progresses through said vessel, and means for recovering a decayed liquid phase of said foamed processing liquor from said vessel and for continually recycling the recovered liquor to said applying means for reapplication to non-persistently foamed condition to said recirculating fabric.
