Abstract

Procédé d'obtention d'une préparation fibreuse pour papier opaque résistant à l'immersion La présente invention a pour objet un procédé d'obtention d'une préparation fibreuse pour fabriquer un papier présentant une hydrophobie et une opacité importantes à l’état sec ou humide remarquable en ce qu'il comporte au moins les étapes suivantes :- mise en suspension de fibres dans de l’eau,- ajout de sels de calcium dans lesdites fibres,- ajout d’une source de sels de carbonates sous forme d’une solution aqueuse,- agitation du mélange obtenu pendant un temps suffisant pour permettre la précipitation de particules de carbonate de calcium,- ajout d’une solution de sels d’acide gras chauffée à une température correspondant à la température de micellisation desdits sels d’acides gras et tenant compte de la concentration micellaire critique desdits sels d’acides gras,- agitation du mélange ainsi obtenu pendant un temps suffisant pour permettre l’adsorption des acides gras à la surface des particules de carbonate de calcium et obtenir la préparation fibreuse souhaitée.
