Title (EN) PROCESS FOR THE PRODUCTION OF NANO-FIBRILLAR CELLULOSE GELS
(FR) PROCÉDÉ DE PRODUCTION DE GELS DE CELLULOSE À STRUCTURE NANOFIBRILLAIRE
Abstract:
(EN) The present invention relates to a process for the production of nano-fibrillar cellulose gels by providing cellulose fibres and at least one filler and/or pigment; combining the cellulose fibres and the at least one filler and/or pigment; and fibrillating the cellulose fibres in the presence of the at least one filler and/or pigment until a gel is formed, as well as the nano-fibrillar cellulose gel obtained by this process and uses thereof.
(FR) La présente invention concerne un procédé de production de gels de cellulose à structure nanofibrillaire consistant à proposer des fibres de cellulose et au moins une charge et/ou un pigment; combiner les fibres de cellulose avec la ou les charges et/ou le ou les pigments; et fibriller les fibres de cellulose en présence de la ou des charges et/ou du ou des pigments jusqu'à formation d'un gel, ainsi que le gel de cellulose à structure nanofibrillaire obtenu par ce procédé et les applications associées.
