Zusammenfassung:	The invention relates to a fibrous sheet having a basis weight of between 20 and 1000 g/m2 being manufactured according to a wet papermaking process, and disintegrating in water in less than 120 seconds, said fibrous sheet comprising 10 to 70% starch and at least 30% of papermaking fibres on the basis of the total weight of the dry fibrous sheet. The sheet is used for instance for the manufacture of a water disintegrable core in a roll of tissue paper. La présente invention a trait à une feuille fibreuse dont le grammage est compris entre 20 et 1000 g/m2, qui est fabriquée conformément à un processus par voie humide de fabrication du papier et qui se désagrège dans l'eau en moins de 120 secondes. Ladite feuille fibreuse comprend 10 à 70 % d'amidon et au moins 30 % de fibres permettant la fabrication du papier sur la base du poids total de la feuille fibreuse sèche. La feuille est utilisée, par exemple, pour la fabrication d'un noyau se désagrégeant dans l'eau dans un rouleau de papier de soie.
