Abstract
L'invention concerne un procédé de fabrication d'un papier extensible. Le procédé comprend les étapes consistant : à prendre des fibres de pâte à papier se présentant sous la forme d'une pâte ayant un premier indice de recoquillement moyen pondéré en longueur ; à traiter mécaniquement les fibres de pâte à papier au moyen d'un procédé de compression de pâte à papier pour provoquer des déformations de fibre de sorte que les fibres de pâte à papier ainsi obtenues présentent un second indice de recoquillement moyen pondéré en longueur supérieur au premier indice de recoquillement moyen pondéré en longueur ; à former une bande humide à l'aide des fibres de pâte à papier traitées mécaniquement ; à sécher la bande humide sous contrainte pour former une bande séchée ; et à ajouter un polymère à la bande séchée. L'invention concerne également un papier extensible qui comprend : des fibres de pâte à papier ayant un indice de recoquillement moyen pondéré en longueur CLw ; et un polymère à hauteur de 2 à 40 % en poids rapporté au poids du papier extensible. Le papier extensible présente une résistance à l'air Gurley inférieure à 20 s/100 mL_ et un allongement à la rupture d'au moins 7 %.
