Abstract (en)

[origin: WO8200485A1] Method for producing a cellulosic sheet (20) capable of being used in high quality grades of tissue and towel, which exhibits outstanding water absorbency properties and a high degree of surface-perceived softness. The method includes the steps of forming a cellulosic web (1), treating that web with a chemical bonding inhibitor (6) so that the pH of the web, after treatment, is not more than about 5.0, and then creping and drying the treated web. The sheet (20) produced by this method has an over-all quality factor and surface-perceived softness factor, respectively, of at least about 1.5.

Abstract (fr)

Procede de production d'une feuille de cellulose (20) pouvant etre utilisee dans des mouchoirs et des serviettes de haute qualite et ayant d'excellentes proprietes d'absorption de l'eau et tres douce en surface. Le procede comprend les etapes de formation d'une bande de cellulose (1), le traitement de cette bande avec un inhibiteur de liaison chimique (6) pour que le pH de la bande, apres traitement, ne depasse pas 5,0 environ, puis le crepage et le sechage de la bande traitee. La feuille (20) produite par cette methode possede un facteur de qualite et un facteur de douceur sensible en surface, respectivement, d'au moins 1,5 environ.
