Abstract:
A spray dyeing machine comprising:a processing tub having a wide passage, an upstream sector and a downstream sector for a fabric to pass therethrough for dyeing and other process operations, said processing tub including an upstream side wall, an upper end of said upstream side wall and an inlet passage on said upper end of said upstream side wall and said processing tub including a downstream side wall, an upper end of said downstream side wall and an outlet passage on said upper end of said downstream side wall; a cloth dragging wheel at each of said inlet and said outlet passages and a cloth collecting tub disposed below said inlet passage in said upstream sector of said passage in said processing tub; a cloth guide tube having upper side walls angularly disposed between said cloth collecting tub and said outlet passage so that the downstream end of said cloth guide tube is higher than its upstream end; a dye nozzle formed on said upper side walls of said cloth guide tube, a pipe and a dye pump connected to said dye nozzle by said pipe for pumping dye or treating liquid through said nozzle whereby the dye or treating liquid is sprayed on a large area of fabric; a plurality of sector separated air guiding nozzles formed along said passage in a lower portion of said side walls of said cloth guide tube; a reflective action base having an upper surface formed in a downstream direction of said air guiding nozzles, a blast machine and a pipe for connecting said blast machine to said guiding nozzles and for providing pressurized air to and through said air guiding nozzles in the form of an air flow whereby the action of the air flow along said upper surface of said reflective action base toward the upstream direction of the fabric so that the pressure below the fabric is lower due to a higher speed of air flow and the pressure above is higher due to a slower air flow, and the upper and lower air flows interact to ensure that the fabric passes through said cloth guide tube with a periodic vibration, said fabric being continuously pushed due to the pressure difference and gravity and having close contact with the air flow to thereby increase the conversion rate so that dye penetrates into the fabric.
