Physical properties of silk fibroin fibers irradiated with rays

Kawahara, Yutaka*; Washika, Shingo*; Ikeda, Yoshimitsu*; Nagasawa, Naotsugu

Silk fibroin fabrics were irradiated with rays of 25 kGy doses, and the changes in their tensile properties and hue were investigated. Both the breaking tensile strength of the fabrics and their elongation at break were decreased after the irradiation, accompanied by their yellowing. However, the values of their tensile properties after the irradiation has been retained more than 90% of those without the irradiation. The degree of crystallinity was almost unchanged even after the irradiation.
