Title (EN) SHEET MATERIAL COMPRISING FIBER AND NANO-MICROSCALE ORGANIC FIBRILLATED FILLER AND METHOD OF PRODUCING SAID SHEET MATERIAL
(FR) MATÉRIAU EN FEUILLE COMPRENANT UNE FIBRE ET UNE CHARGE FIBRILLÉE ORGANIQUE NANOMÉTRIQUE ET PROCÉDÉ DE PRODUCTION DUDIT MATÉRIAU EN FEUILLE
Abstract:
(EN) This invention relates to a sheet material comprising fiber and nano-microscale organic fibrillated filler, wherein the nano-microscale organic fibrillated filler comprises microfibrillated cellulose and starch granule in such a way that the microfibrillated cellulose is dispersed with starch granule, and the nano-microscale organic fibrillated filler has starch granule at least 15 wt%. Besides, this invention also relates to a method of producing said sheet material comprising fiber and nano-microscale organic filler, wherein the method comprises the steps of (i) preparing pulp suspension, (ii) preparing nano-microscale organic fibrillated filler, (iii) adding the nano-microscale organic fibrillated filler into the pulp suspension, (iv) forming sheet material by pressing, and (v) drying the sheet material, wherein the preparation step of nano-microscale organic fibrillated filler provides the nano-microscale organic fibrillated filler comprising microfibrillated cellulose and starch granule in such a way that the microfibrillated cellulose is dispersed with starch granule.
(FR) La présente invention concerne un matériau en feuille comprenant une fibre et une charge fibrillée organique nanométrique, la charge fibrillée organique nanométrique comprenant de la cellulose microfibrillée et un granulé d'amidon de telle sorte que la cellulose microfibrillée soit dispersée avec un granulé d'amidon et que la charge fibrillée organique nanométrique présente le granulé d'amidon d'au moins 15 % en poids. En outre, la présente invention concerne également un procédé de production dudit matériau en feuille comprenant une fibre et une charge organique nanométrique, le procédé comprenant les étapes consistant à (i) préparer une suspension de pâte, (ii) préparer une charge fibrillée organique nanométrique, (iii) ajouter la charge fibrillée organique nanométrique dans la suspension de pâte, (iv) former un matériau en feuille par pressage et (v) sécher le matériau en feuille, l'étape de préparation de la charge fibrillée organique nanométrique fournissant la charge fibrillée organique nanométrique comprenant de la cellulose microfibrillée et un granulé d'amidon de telle sorte que la cellulose microfibrillée soit dispersée avec un granulé d'amidon.
