Abstract

« Pâte à papier et ses utilisations » La présente invention concerne une pâte à papier comprenant :- une teneur en matière minérale d’au moins 30% en poids,- une teneur en polysaccharides non cellulosiques d’au moins 10% en poids, et- une teneur en polysaccharides cellulosiques d’au moins 8% en poids,chaque pourcentage étant exprimé en poids par rapport au poids total de la matière sèche contenue dans la pâte à papier. La présente invention concerne également le procédé de fabrication du papier à partir de cette pâte à papier et leurs utilisations, notamment pour la fabrication de tout type d’objet tridimensionnel en cellulose moulée."Paper pulp and uses thereof" The present invention relates to a paper pulp comprising:- a mineral content of at least 30% by weight,- a non-cellulosic polysaccharide content of at least 10% by weight, and - a cellulosic polysaccharide content of at least 8% by weight, each percentage being expressed by weight relative to the total weight of the dry matter contained in the paper pulp. The present invention also relates to the process for the manufacture of paper from this paper pulp and their uses, in particular for the manufacture of any type of three-dimensional object in molded cellulose.
