Title:
WATERPROOF CELLULOSE SHEET, AND WATERPROOF-CELLULOSE-SHEET PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/072231
Kind Code:
A1
Abstract:
This waterproof cellulose sheet comprises cellulose nanofibres provided with functional groups represented by -COOA, and has an elongation at break of at least 3%. A in the functional groups represented by -COOA represents an alkali metal, an alkaline earth metal, or hydrogen. At least 20% but less than 90% of the functional groups represented by -COOA are -COOH groups. Accordingly, provided is a waterproof cellulose sheet exhibiting excellent waterproofness and transparency.
