CA 2241517

Sanitary paper with improved softness (lower stiffness) can be obtained without significant loss of paper strength by using a papermaking pulp which is treated with a certain type of cellulase component. The cellulase component in question is characterized by not containing a cellulose-binding domain (CBD), and is more effective for making softer sanitary paper than a conventional cellulase preparation which contains a mixture of various cellulase components with and without a CBD.

Cette invention concerne un papier à usage hygiénique d'une plus grande douceur (d'une rigidité moindre), que l'on peut produire sans perte importante dans la résistance du papier en utilisant de la pâte à papier traitée avec un certain type de composant de cellulase. Le composant cellulase en question se caractérise par le fait qu'il ne contient pas de domaine de fixation de la cellulose (CBD), et qu'il est plus efficace, dans la préparation de papier à usage hygiénique d'une plus grande douceur, que les préparations à la cellulase traditionnelles qui contiennent un mélange de divers composants de cellulase avec et sans CBD.
