Article Preview

The as-spun fibers, which be produced by dry spinning technique, were treated with methanol solution. The results showed that the morphology, structure and mechanical properties of the as-spun fibers had changed. Before methanol treatment,the as-spun fiber had a smooth surface, after methanol treatment, the fiber exhibited rough surface and banded features along the fiber axis. The structure of the as-spun fibers changed from random-coil or silk I conformation to silk II conformation and the breaking intensity of the as-spun fibers were improved after methanol treatment. Compared with degummed silk fibers, the fibers treated with methanol had higher module, but the breaking elongation was lower, the fibers were still brittle.
