織物光沢の質感表示についての検討

抄録

Few investigations on the quality of fabric luster has been made, and “Micro luster” given by M. Sawaji¹⁾ seems to be the only method to express the quality.
In the previous paper⁴⁾, we thought that the main factor controling the quality of fabric luster was the internal reflecting element from heaped fiber bundle in the fabric, and a method using “polarized light”. It is considered that there are some differences in the conception between our polarized light and micro luster methods.
In present paper, the relation between both methods and the physical meaning of the quality of fabric luster are discussed by means of visual test and measurement of microscopical reflecting properties of fabric.
Main results obtained are as follows:
The conception of two methods (“micro luster” and “polarized light”) are similar.
The quality of fabric luster is characterized by two factors. One is the reflecting coefficient of reflecting element from fabric that possesses the directionality and the other the diffused element from fabric.
This is consistent with the conceptions of the above two methods.
On the basis of these results, one can obtain the meanings for the visual estimating terms of the quality of fabric luster.
