Measurements of small angle X-ray diffraction and mechanical properties showed that wild silk fibers had a porous structure and that their fibrils had a zig-zag structure unlike domestic silk fibers. This structure explained why wild silk fibers had a larger creep elongation in ethanol than domestic silk fibers. The treated wild silk fibers had a larger specific gravity and a wider small angle X-ray scattering pattern than those of untreated wild silk fibers. During creep elongation in ethanol, the beta structure was formed, and the fibrils were stretched. The specific gravity of the non-crystalline region and the crystallinity index were measured. The crystallinity index depended on the spinning conditions. 8 refs.
