CA 2197485

Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.

On peut fabriquer des feuilles de papier servant de papier hygiénique, d'essuie-tout, de serviettes de table, de produits absorbants jetables et autres articles semblables qui démontrent un haut degré de résilience à l'état humide. On obtient cette propriété en utilisant une combinaison de fibres de pâte à haute limite d'élasticité (telles les fibres de pâte chimiothermomécanique blanchie) et un agent de résistance à l'état humide dans un procédé de séchage à air traversant sans crêpage. Le produit résultant, lorsqu'il est mouillé, peut se redéployer après avoir été froissé.
