CA 2509514

The present invention relates to a filler-fiber composite, a process for its production, the use of such in the manufacture of paper or paperboard products and to paper produced therefrom. More particularly the invention relates to a filler-fiber composite in which the morphology and particle size of the mineral filler are established prior to the development of the bond to the fiber. Even more particularly, the present invention relates to a PCC filler- fiber composite, wherein the desired optical and physical properties of the paper produced therefrom are realized.

L'invention se rapporte à un stratifié matériau de charge/fibres, son procédé de production, son utilisation pour générer des produits de type papier ou carton, ainsi qu'au papier ainsi produit. De manière plus spécifique, cette invention concerne un stratifié matériau de charge/fibres dans lequel la morphologie ainsi que la grosseur des particules du matériau de charge minéral sont établies avant que la liaison avec les fibres ne soit développée. De manière encore plus spécifique, la présente invention concerne un stratifié matériau de charge/fibres PCC permettant de produire un papier présentant les propriétés optiques et physiques souhaitées.
