A dyeing method of a fiber by using organic pigment in a cold bath is provided to prevent the waste water after dyeing from generating and to have the specific impression of a color. Water of 19 to 21kg is fed into the dyeing bath. Water-soluble resin adhesive(binder) of 300 to 900g, casein of 290 to 310g, organic pigment of 30 to 400g, anion surfactant of 30 to 50g are injected into the water, mixed properly and agitated so that the dyeing solution is produced. A fabric to be dyed of 4.9 to 5.1kg is immersed into the dyeing bath having the dyeing solution. Thereafter, the fabric dyed by the dyeing solution is dehydrated. The dehydrated fabric is dried naturally as an equilibrium state. The naturally dried fabric is treated at the temperature of 110 to 130 degrees centigrade for 30 to 40 minutes so that the dye is fixed to the fabric. The dyestuff of 2 to 20g or glacial acetic acid of 100g is melted into the water with the temperature of 50 degrees centigrade, cooled and also injected together with the dyeing solution. |
