  • Patent number: 5894747
    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.
