The invention relates to a process for manufacturing paper, in which a filler is pretreated and suspended to form an aqueous slurry, the aqueous slurry obtained is combined with an aqueous suspension containing cellulose fibres to form a stock, the stock obtained is treated at least with a cationic retention agent and the treated stock is filtered to form paper. Retention and optical properties are improved by the filler being pre-treated with inorganic colloidal particles having an average size less than 100nm.

L'invention concerne un procédé pour une fabrication de papier, dans laquelle une charge est prétraitée et suspendue pour former une boue aqueuse. Cette boue aqueuse est combinée à une suspension aqueuse contenant des fibres cellulosiques pour former une solution de réserve. Cette solution de réserve est traitée au moins au moyen d'un agent de rétention cationique, et la solution de réserve traitée est filtrée pour former du papier. Des propriétés de rétention et des propriétés optiques sont accrues par le biais d'un traitement de la charge au moyen de particules colloïdales inorganiques présentant une taille moyenne inférieure à 100 nm.
