description | The invention relates to a method for producing paper with internal sizing, comprising the following steps consisting in: a) preparing cellulose fibres, b) treating the fibres obtained in step a) with an enzyme-mediator system comprising a laccase-type oxidative enzyme and a mediator which is a natural or synthetic product containing a phenol group or an alcohol in the structure thereof, and c) producing paper using the treated fibres.
La presente invención se refiere a un procedimiento para la fabricación de papel con encolado interno que comprende las etapas de: a) preparación de fibras celulósicas; b) tratamiento de las fibras obtenidas en la etapa a) con un sistema enzima-mediador que consiste en una enzima oxidativa tipo lacasa y un mediador que es un producto natural o sintético que comprende en su estructura un grupo fenólico o un alcohol, y c) fabricación del papel con las fibras tratadas.
La présente invention concerne un procédé pour la fabrication de papier à encollage interne qui comprend les étapes suivantes: a) préparation de fibres cellulosiques; b) traitement des fibres obtenues dans l'étape a) avec un système enzyme-médiateur qui est constitué d'une enzyme oxydative de type lacase et d'un médiateur qui est un produit naturel ou de synthèse renfermant dans sa structure un groupe phénolique ou un alcool, et c) fabrication du papier avec les fibres traitées. |
