Title:
CELLULOSE FIBER SUSPENSION AND MANUFACTURING METHOD THEREFOR, AND FILM-LIKE FORMED BODY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/074341
Kind Code:
A1
Abstract:
Disclosed is a cellulose fiber suspension suitable as a manufacturing material for an oxygen gas barrier film. This cellulose fiber suspension contains cellulose fibers, a multivalent metal, and a volatile base, with the cellulose fibers having a mean fiber diameter of 200 nm or less, and the amount of carboxyl groups contained in the cellulose which forms the aforementioned cellulose fibers being 0.1-2 mmol/g. This suspension is suitable as a film material having an oxygen gas barrier property. Further disclosed is a film-like formed body having cellulose fibers and an inorganic metallic salt or an organic metallic salt, with the aforementioned cellulose fibers including cellulose fibers having a mean fiber diameter of 200 nm or less, and the amount of carboxyl groups contained in the cellulose which forms the aforementioned cellulose fibers being 0.1-2 mmol/g.
