Abstract
The effects of weave on the luster of silk fabrics, noted particularly on the difference in them due to whether fabrics are white or dyed black, were investigated by visual evaluation and goniophotometry. Eight sample fabrics different in weave but the same in weave density as well as in yarn count were tested, the results of which revealed that the weave effect on luster was more outstanding for white fabrics than for black ones, both in visual valuation and in reflectometric one. Especially for the cases where the eight white samples were judged visually in the weft direction, the statistical analyses (of variance, correlation, and principal factors) of the obtained scores suggested that the eight kinds of weave might be grouped into four types that corresponded to four patterns of angular distributions of reflected light.
