Abstract

Silk fibers from the Japanese oak silkworm, Antheraea yamamai, were treated with hot dimethylsulfoxide, DMSO, and the changes in fiber structure were investigated. The treatment proceeded the structural modification of sericin to the pleated β sheet structure, and promoted the crystallization of fibroin. Then the mechanical properties for the fibers were enhanced and the degree of fibrillation was suppressed at mill tests. The hot DMSO treatment seems to be effective to control the fibrillation behavior of the Japanese oak silk fibers.
