The structure characteristics of silk plain fabrics were studied by means of high speed scanning microscopy (E. D. P.) pattern and the contact printing image.
The results obtained are summarized as follows.
1. The areas of the openings in the fabrics were 11-12% (gray), 3% (habutae) and 2% (crape). The shapes of the openings were: habutae and gray fabrics, in slit form with symmetry in respect to the perpendicular axis, and crape, in fusi- or triangle form with unsymmetry in respect to the perpendicular axis.
2. E. D. P. patterns were observed as checked patterns which differed depending on the warp shifting up and down at the intersection of warp and filling lines.
3. Judging from the optical properties, the fine structures of the silk plain fabrics were figured in detail in the fraunhofer diffraction patterns of the contact printing images.
4. In the fraunhofer pattern of E. D. P. pattern, the diffusion around the interference points are observed as equivalent density outlines.
5. Fraunhofer patterns of the silk plain fabrics contain exact informations of the area, number, form, size and position of the opening.
