Abstract
A continuous dyeing method for long original tufted carpets, including applying a dyeing liquid to the carpet while running it in the longitudinal direction with a continuous dyeing machine that includes a dyeing liquid supply applicator having an independent supply route A and supply route B, each having a plurality of nozzles capable of applying dyeing liquid to the original tufted carpet so as to uniformly flow onto the original tufted carpet through a plate. The nozzles of supply route A and supply route B are alternately aligned in the width direction, with at least one of the nozzles of each of supply routes A and B opened by the control of an opening means. The present continuous dyeing method is capable of easily dyeing an original tufted carpet a mixture of colors and/or various patterns by gradation.
