Design and production of new composite raw silk from Antheraea yamamai and Bombyx mori

Abstract

In order to design and develop a novel raw silk with more desirable qualities, a new type of composite raw silk produced by Antheraea yamamai and Bombyx mori was investigated. The results can be summarized as follows: (1) It was possible to produce composite raw silk with a sheath/core structure with a range from 61/39% to 82/18% in the fiber composition of Antheraea yamamai and Bombyx mori silk; (2) For the range of fiber composition for Antheraea yamamai and Bombyx mori silk, a close correlation between the results of the theoretical calculations and the experiment was noted; (3) In the production of composite raw silk, it was necessary to control the core tension and/or the dissociating tension by adjusting
