Color appearance simulation method for multilevel loop tufted carpet produced by single needle bar machine

To provide the designer preview of the final color appearance of tufted carpet, this paper proposed a computer aided method to simulate the color appearance of tufted carpet which is made with different color yarns. The simulation method adopts a color block to represent a single loop pile in the carpet surface, and through adjusting color block size to simulate the extrusion between loop piles. The method starts from scanning the control pattern to analyze the color information for each pixel in control pattern, and convert color into the pile height level information. Base on the current and surrounded loop piles height level to infer the size and start point of color block for current loop pile. According the cam pattern, creel pattern, and color block information to generate the color appearance simulation for the tufted carpet. Test result shows that this method can effectively generate carpet color appearance simulation for tufted carpet comprising of multicolor yarns.
