摘要:
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.
摘要:
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. In addition, a steam jet nozzle is provided for treatment and also to provide a driving impetus to the rope as it travels through the machine. The nozzle is formed with an annular housing having a wide steam accumulation chamber connected to a narrow supply passage leading upstream to a wide distribution chamber from which the steam flows downstream through a delivery passage to an annular orifice opening at a downstream inclination into the interior housing through which the rope travels.
摘要:
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. As the fabric leaves the cloth discharge tube and contacts the inner chamber, the dye liquid leaves the fabric through the perforations of the inner chamber. A plastic liner is placed along the floor of the inner chamber in order to assist the movement of the plug of fabric from the entrance to the outlet of the inner chamber. The inner chamber has a cross section which increases in depth from the entrance to the outlet to allow the fabric plug to progress from the entrance to the outlet with less and less binding. Beneath the vessel is a pump suction header which maximizes the net positive suction pressure for the pump which recirculates the dye from the pressure vessel to the non-clog jet venturi.
