Title
(EN) METHOD FOR MAKING SOFT TISSUE USING CATIONIC SILICONES
(FR) PROCEDE DE FABRICATION DE PAPIER DOUX A USAGE MENAGER PAR UTILISATION DE SILICONES CATIONIQUES
Abstract
(EN)
The addition of a relatively small amount of a cationic silicone to the aqueous suspension of papermaking fibers in the wet end of the tissue making process provides improved tactile properties (softness) to the resulting tissue.
(FR)
La présente invention consiste à ajouter une quantité relativement faible d'un silicone cationique dans la suspension aqueuse de fibres servant à la fabrication du papier, au niveau de l'extrémité humide du processus de fabrication, pour conférer au papier à usage ménager obtenu certaines propriétés tactiles (de douceur).
