Title
(EN) SOFT TISSUE PAPER FROM COARSE CELLULOSE FIBERS
(FR) PAPIER DOUX POUR SERVIETTES OBTENU A PARTIR DE FIBRES DE CELLULOSE GROSSIERES
Abstract
(EN)
Tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and napkins are provided. The tissue papers comprise chemically softened cellulose fibers comprising coarse cellulose fibers such as those derived from chemi-thermomechanical or recycled sources. The cellulose fibers have enhanced lubricity such that they possess a depressed coefficient of friction (DCOF, in percentage points) related to the composite average coarseness, C, in mg/100m, by the equation: DCOF > 4.27*C-44.23.
(FR)
On décrit un papier utile pour réaliser des produits doux et absorbants convenant à des articles d'hygiène personnelle, tels que les tissus pour le visage, les serviettes des salles de bains et les couches. Le papier doux contient des fibres de celluloses assouplies chimiquement, obtenues à partir de fibres de cellulose grossières telles que celles provenant de traitements chimio-thermo-mécaniques ou celles provenant de recyclages. Les fibres de cellulose glissent mieux du fait qu'elles présentent une diminution du coefficient de friction DCOF exprimé en pourcentage par comparaison avec des fibres d'une grossièreté moyenne C exprimée en mg/100m, donnée par l'équation DCOF > 4,27*C-44,23.
