INFLUENCES OF TEXTURE ON THE FABRIC LUSTER (QUALITY)

In the previous paper, the quality of luster of fabrics was discussed from the standpoint of a heap film.In this paper, it is discussed mainly the influences of texture on the fabric luster (quality).The results obtained are as follows:1. The luster (quality) of textured surface is equal to that of the plane excluding the texture of fabric, when the size of textures is larger than the analytical ability of human eyes, while, when the size is beyond the abitity, it is determined by ∑ (reflecting distribution of texture).2. In fabrics, the parallel property of fiber affects the fabric luster. This is caused by the change of directional properties of reflecting elements at the boundary of fiber and air relating with parallel property of fiber.3. The relation between the luster of satain weave and of heap films which is asumed to have a plane excluding the texture of fabric becomes clear in this study.The quality of luster is expressed on the same coodinate system as that of plane materials.
