説明

Molecular conformation, crystalline structure and mechanical properties of cocoon filaments of Bombyx mandarins, which is assigned to the Bombyx mori genus, were studied by infrared spectrometry, x-ray diffractometry, scanning electron microscopy and stress-strain measurement.<br>The cocoon filaments of Bombyx mandarina were slightly twised with a ribbon-like form, and cubic crystals of calcium oxalate were observed on the surface of the filaments as in the case of the fibroin filaments of silk for an non-mulberry silkworms. Longitudinal lines were observed on the degummed cocoon filaments. The denier of the cocoon filament of Bombyx mandarina was slightly smaller than that of Bombyx mori and the degumming loss (27%) was higher than that of Bombyx mori silk.<br>Molecular conformation, crystalline structure, mechanical properties, elasticity recovery and thermal decomposition temperature of Bombyx mandarina proteins were similar to those of Bombyx mori silk proteins.
