Abstract

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.
