Abstract: An improved low liquid gentle jet dyeing machine which has a pressure vessel with one or more inner chambers located interior to and spaced from the interior edges of the pressure vessel. An endless rope of fabric is contained within each inner chamber. The fabric is plaited to form a plug in the inner chamber. A rotatable perforated barrel reel lifts the fabric from this plug through the outlet of the inner chamber. The fabric then enters a jet dyeing chamber which contains a parallel flow non-clog venturi disposed so as to gently impregnate the fabric with dye liquid. The fabric exits the jet dyeing chamber through a cloth discharge tube which is disposed to convey the fabric to the entrance of the inner chamber in such a way that the angular change of direction of the fabric is minimized. The side walls and floor of the inner chamber are perforated, with the number of side wall perforations being greater toward the chamber entrance and lesser toward the chamber outlet.

Abstract: A wet processing jet machine for treating textile piece goods in rope form at a low liquid ratio. A plug supporting tube is provided as a vertical extension of a U-shaped processing chamber. The sides of the chamber are perforated and the bottom is imperforate for enhanced movement of the plug through the chamber. The tube extension is perforated to allow flow of liquid therefrom for enhanced plaiting. The amount of liquid with the rope in the plug is minimized for low liquid requirements and the head of the plug causes the plug to progress through the chamber above the low level of the liquid in the bottom of the vessel, which liquid level is below the bottom of the chamber or at least at a level that does not cause substantial floatation of the plug. The rope entering the tube is plaited by passing through an inverted frusto-conical plaiting nozzle that is oscillated and reciprocated to provide effective plaiting.

Abstract: A textile wet processing machine of the type wherein an endless fabric rope is circulated in plug form through a U-shaped chamber having perforated side walls is equipped with an inner wall having lateral flanges for mounting by special fasteners in differing dispositions between the chamber side walls utilizing the existing perforations therein to selectively vary the cross-sectional size of the chamber to accommodate particular processing requirements of differing fabrics.
