Morphology of the Fibers
Morphology of the A. atlas fibers after degumming are shown in Figs. 4 and 5. Longitudinally, the fibers have a clean and smooth surface as seen from Figure 4. Fig- ure 5a and b reveals that the fibers are flat and rib- bon-like and have a solid cross-section. The morphol- ogy of the A. atlas fibers is similar to that of the wild silk but different than B. mori silk that have a triangular cross-section.
