Title
(EN) PROCESS FOR PRODUCING SHORT-FIBERED SOFTWOOD PULPS
(FR) PROCEDE POUR PRODUIRE DES PATES A PAPIER CONSTITUEES DE FIBRES COURTES, A PARTIR DE BOIS DE CONIFERES
Abstract
(EN)
Process for utilizing softwood pulp for the production of paper and board, where essential product properties, e.g. a good print quality are obtained by controlling the fibre length distribution of the pulp through enzymatic treatment, followed by a mechanical or other equivalent treatment of the fibres.
(FR)
L'invention concerne un procédé utilisant de la pâte à papier de conifères pour la production de papier et de carton dont les qualités essentielles comme par exemple une bonne qualité d'impression sont obtenues en modifiant la répartition des longueurs des fibres par un traitement enzymatique, suivi par un traitement mécanique des fibres, ou par un autre traitement équivalent.
