Abstract
A system for monitoring and controlling the color and shade in a decolorization or fading process for textiles. The system contains a visible light source which illuminates a sample of a dyed textile. A scanner reads the illuminated sample and provides an optical image which is sensed by optical transducers which transforms it into an representative electronic signal which is analyzed for a chroma signal component (image color content) and/or luminance component (image shade/gray scale content). A process control computer monitors and adjusts the process speed and at predetermined color and shade finish stops the decolorization process based on the measured and processed image contents which is tracked by a calibrated and sensed optical image represented by processed electronic signals.
