COCOON-SHAPED CELLULOSE AGGREGATE, COCOON-SHAPED CELLULOSE AGGREGATE-CONTAINING CELLULOSE NANOFILLER, RESIN COMPOSITION CONTAINING THE CELLULOSE NANOFILLER, AND RESIN MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a new nanofiller which brings about an excellent mechanical property value of a resin composition compounded therewith, and yet which is easily compounded with a resin.SOLUTION: A problem is solved by providing a cocoon-shaped cellulose aggregate obtained by flocculating cellulose nanofiber in a cocoon shape, and cellulose nanofiller containing the cocoon-shaped cellulose aggregate, and a method for producing the cellulose nanofiller. Also a cellulose nanofiber composition containing the cocoon-shaped cellulose aggregate and additionally the cellulose nanofiber, and a cellulose nanofiber composition-containing cellulose nanofiller are provided. Furthermore, a cellulose nanofiller-containing resin composition containing the cellulose nanofiller and a resin for molding, and a molded article thereof are provided.
