Color appearance of textile materials applied to various geometrical shapes

The color of textile products is mainly controlled during the material production process, e.g. dyeing or printing, using color management protocols. Little attention has been given to researching the color appearance of the textile material applied to final products, where textile material is applied to a shape. The results are reported of research into the color appearance of textile materials of varying material characteristics, color, and geometrical shape to which they are applied. The main focus was on determining color differences between real textile material color and the perceived one. Materials were characterized by their composition, fabric structure, fiber type, thread count, surface characteristics, and glossiness. Samples of red, blue, orange, violet, and green color were chosen as the most frequently used colors in real application. Textile materials were applied on three differently shaped objects (flat surface, cube, and cylinder). The object color was determined by objective instrumental measurements as well as subjective judgment. A specially constructed light chamber was used to ensure constant experimental conditions. Data were subjected to statistical analysis in order to determine differences of each CIE Lch color coordinate. Results indicate significant effects of objects shape on color appearance.
