ABSTRACT:
Objects molded of synthetic resin such as slide fastener sliders are dyed with a dye liquor having a bath ratio appropriate for an actual amount of dyestuff to be applied to the objects which has been determined from the outer surface area of the objects and the thickness of a dye layer to be formed thereon. The dye liquor is brought into contact with the objects while the dye liquor is being supplied in circulation through a dyeing tank or contained together with the objects in the dyeing tank.
