Title (EN) HIGH-STRENGTH SHEET MATERIAL
(FR) MATÉRIAU EN FEUILLE À HAUTE RÉSISTANCE
Abstract:
(EN) The present invention relates to a high-strength sheet material comprising: (a) cellulose or cellulosic material; and (b) an additive comprising chemically modified hemicellulosic beta- glucan selected from cationically modified hemicellulosic beta-glucan, anionically modified hemicellulosic beta-glucan, amphoterically modified hemicellulosic beta-glucan or a mixture of at least two of said chemically modified hemicellulosic beta-glucans. According to the present invention, said high-strength sheet material further comprises a crosslinking agent forming one or more network structures selected from a network of cellulose, a network of chemically modified hemicellulosic beta-glucans, or a network of cellulose and chemically modified hemicellulosic beta-glucans.
(FR) La présente invention concerne un matériau en feuille à haute résistance comprenant : (a) de la cellulose ou un matériau cellulosique ; et (b) un additif comprenant du beta-glucane hémicellulosique chimiquement modifié choisi parmi le beta-glucane hémicellulosique modifié de manière cationique, le beta-glucane hémicellulosique modifié de manière anionique, le beta-glucane hémicellulosique modifié de manière amphotère ou un mélange d'au moins deux de ces beta-glucanes hémicellulosiques chimiquement modifiés. Selon la présente invention, ledit matériau en feuille à haute résistance comprend en outre un agent de réticulation formant une ou plusieurs structures de réseau choisies parmi un réseau de cellulose, un réseau de beta-glucanes hémicellulosiques chimiquement modifiés, ou un réseau de cellulose et des beta-glucanes hémicellulosiques chimiquement modifiés.
