Title (EN) PRODUCTION OF SOFT PAPER PRODUCTS FROM HIGH AND LOW COARSENESS FIBERS
(FR) PRODUCTION DE PAPIER DOUX A PARTIR DE FIBRES GROSSIERES ET DE FIBRES FINES
Abstract:
(EN) Paper products such as bathroom tissue, facial tissue, napkins and paper towels are made from high coarseness fibers such as recycled newsprint fibers, CTMP, TMP, and groundwood. These products exhibit premium level qualities in terms of softness, bulk, and flexibility. The novel process selectively treats these high coarseness fibers in a way that makes the fibers feel softer and enhances papermachine operation with this type of furnish, thereby permitting higher product quality levels than previously possible with high coarseness fibers.
(FR) Des papiers du type serviette pour le corps ou pour le visage, couches pour bébés et papier hygiénique, sont réalisés à partir de fibres grossières provenant, par exemple, de journaux recyclés, de pâte thermomécanique, de pâte chimicothermomécanique ou de pâte mécanique. Ces produits sont de première qualité, du point de vue douceur au toucher, volume, et flexibilité. Le nouveau procédé permet de traiter sélectivement ces fibres grossière de manière à les rendre plus douces au toucher, facilite les opérations de fabrication du papier avec ce type de composition, et permet d'obtenir avec des fibres grossières des produits de meilleure qualité qu'il n'était possible antérieurement.
