ABSTRACT:
A method is disclosed for forming a strong, soft, fibrous sheet material having substantial stretch in all directions in its own plane, by applying a pattern of bonding material to a fibrous web, adhering only portions of the web containing bonding material to a creping surface, removing the web from the creping surface by a creping blade to differentially crepe it, whereby a combination of high strength, softness, and bulk are imparted to the web. Sheet materials formed by the above method are also disclosed.
