To study the analysis of fabric structure and classification in the silk fabric, it is necessary to make clear upon the geometrical arrangement of silk fibers in yarns, and yarns in fabric. For this purpose, Fraunhofer diffraction is effective to classify silk plain fabric. We measured on Fraunhofer diffraction using ‘Crape’ which is one of typical silk plain fabrics.
The results obtained are as follows:
1) To apply Fraunhofer diffraction method for two dimensional structure of silk plain fabric having stereo-structure, the pattern of fabric projects was used. By this method, some structure of yarn and fabric can be detected.
2) In the standardized specimens of Crape silk fabrics, creping fabrics are ranked by Fraunhofer diffraction patterns. This ranking has good correlation with the results of the projection method.
3) It was found by means of Fraunhofer pattern that size and form of creping were greatly differed by the yarn number per cm of fabric and yarn denier.
