Silk thread with dispersion reinforced cellulose nanofibers

Realization of silk thread with uniformly dispersed CNF! Increased mechanical strength by feeding techniques!!

Overview

　Recently, cellulose nanofiber (CNF) has attracted attention as a new material. Although it is expected to be used as a filler to improve mechanical strength by dispersing CNF into a base material such as resin, it is still a problem because of insufficient orientation and dispersability in the base material. 　

　The present invention has been made in view of such problems. Focusing on silk fibers as a base material, we have succeeded in providing a technique for obtaining silkworm silk obtained by uniformly dispersing CNF.
