Abstract
Fabrics woven of fine-filament warp yarns of certain colors and fine-filament filling yarns of certain other colors-the so-called “Tamamushi” (iridescent) fabrics in Japanese-change in surface color by the deformation, rotation and inclination of the fabric surfaces. The causes of this color change have been examined by measuring the surface reflectance with a photoelectric spectrophotometer and by measuring the color difference with Hunter's color difference meter. These measurements have shown that a great color effect for “Tamamushi” fabrics is obtainable by weaving fabrics from warp and filling yarns having chromaticity points over a long distance in the UCS diagram.
