On-line color monitoring in continuous textile dyeing

Abstract This paper describes how on-line color monitoring could be used as part of an ultrasound enhanced continuous textile dyeing system. The current state-of-the-art of color measurement and control in textile manufacturing is reviewed. The use of ultrasound in a closed-loop dyeing system is proposed. The current status of on-line color monitoring which would be required is presented. Some possible solutions to measuring the color of wet fabric have been developed.
