Abstract
L'invention concerne une composition de papier chargé comprenant des fibres de cellulose intactes ainsi que des matières de charge, dans laquelle les fibres de cellulose sont à l'origine constamment humides, et dans laquelle la matière de charge se trouve dan s un précipité insoluble formé in situ à l'intérieur de la paroi cellulaire des fibres de pâte de cellulose constamment humides. La composition de papier chargé est caractérisée en ce qu'ell e présente des caractéristiques de résistance supérieure par rapport à une composition de papier chargé classique correspondante contenant la même quantité de la même matière de charge. L'invention concerne également un procédé de production de papier chargé utilisant des fibres de pâte constamment humides ainsi qu'une matière de charge comprenant un précipité insoluble lequel est précipité in situ à l'intérieur de la paroi cellulaire des fibres. Le procédé consiste premièrement à immerger les fibres de pâte constamment humides dans une première solution contenant un ou plusieurs sels solubles, à filtrer les fibres de pâte de la première solution, puis à réimmerger les fibres de pâte constamment humides contenant la première solution se trouvant dans les pores dans une seconde solution, ladite seconde solution comprenant un ou des sels solubles différents de ceux de ladite première solution et capables de former un précipité insoluble avec le ou les sels de ladite première solution. Les fibres de pâte chargées, constamment humides sont filtrées puis sont lavées, et soit sont utilisées pour former des produits de papiers chargés soit sont séchées pour obtenir des fibres de pâte chargées destinées à une utilisation ultérieure dans la fabrication de papier.
