    • PURPOSE: To reduce labor in dyeing by controlling a liquid injecting part, a liquid circulating part and a liquid discharging part, changing dyeing solutions, dyeing promoter solutions and mordant solutions and spraying the solutions to a material to be dyed. CONSTITUTION: In dyeing a material to be dyed such as Oshima pongee with a dye of tree or plant, a dyeing solution such as an extracted solution of Rhaphiolepis umbellata is injected through a liquid injecting part 1 to the dyeing tank 6 by a control part 4 in state of the material to be dyed hung between a pair of upper and lower arms 64 and 65 installed in a dyeing tank 6. The dyeing solution passed through the bottom part of the dyeing tank 4 through a main route 46, a liquid circulating part 2 consisting of a valve 33 and a pump 34 and optionally through a heating part 7 is spayed from the lower arm 65 upon the material to be dyed being circulated and moved by revolution of the upper arm 64. The material to be dyed is imparted with the dyeing solution which is passed through the above route from the main route 46 while being jetted again. A valve 3 is opened, the dyeing solution is discharged, then a valve 9 is opened and cooling water is made to flow along the inner wall of the dyeing tank 6 and cooled. Then, a dyeing promoter solution such as lime water and a mordant solution such as a DOROZOME (mud dyeing) solution are successively injected through the liquid injecting part 1 to the dyeing tank 6 and the material to be dyed is treated by the same steps to complete dyeing.
