Study of Goniophotometric Color Measurements on “Tamamushi” Fabrics

Abstract

This paper discusses the optical color of the so called Tamamushi fabrics (iridescent fabrics) by the use of the goniophotometric color measurement apparatus with 45° and 60° in incidence angle and 0°75° in receiving angle.
The results obtained are :
1) The change of the color on the Tamamushi fabrics depends on the fabric color value, i.e., Y-valuein each receiving angle.
2) The chromaticity coordinates in chromaticity scale diagram shows the higher purity value in the small angle of receiving, and approaches to the point of light source color in the large angle of receiving.
