Abstract (en)
[origin: WO2022097095A1] An enhanced cellulose nanofibrils (CNF) (or enhanced CNF binder), methods of making the enhanced CNF binder, methods of making wet-laid, dry-laid, or molded articles with the enhanced CNF binder by incorporating the enhanced CNF with the furnish in the wet-end of a paper-making process, methods of coating cellulose-based materials, intermediate formed fiber articles, and/or molded articles with the enhanced CNF binder, and cellulose-based articles obtained by all of these methods, wherein the enhanced CNF includes a saccharide fatty acid ester-, glyceride-, fatty acid salt-, natural wax- and/or cellulose crosslinker- (SGF) blend bound to the CNF.
