摘要

PROBLEM TO BE SOLVED: To provide useful sericin nanofibers and sericin/fibroin composite nanofibers which can be obtained by electrospinning and can be water-insolubilized, and methods for producing the same; to provide a technology for water-insolubilizing these nanofibers; and to provide a material with enhanced dyeability, a metal ion adsorbent and a material with enhanced chemical resistance which comprise the water-insolubilized nanofibers.;SOLUTION: The sericin nanofibers comprise silk sericin. The silk sericin is sericin derived from cocoon layers of naked pupae (gene symbol Nd), sericin silkworms (gene symbol Nd-s) or Sericin Hope, or the silk sericin is liquid sericin in silk glands taken out of the interiors of these silkworm larvae or sericin obtained by coagulation of the liquid sericin. The water-soluble nanofibers obtained are water-insolubilized and chemically processed to provide the material with enhanced dyeability, the metal ion adsorbent and the material with enhanced chemical resistance which comprise the water-insolubilized nanofibers. The composite nanofibers comprise silk sericin and silk fibroin.;COPYRIGHT: (C)2012,JPO&INPIT
