Abstract
Disclosed is a cellulosic fibrous structure, particularly a consumer product such as toilet tissue, facial tissue or a paper towel. In a first embodiment, extending outwardly from each face of the cellulosic fibrous structure is a plurality of protuberances. The protuberances extend bilaterally outwardly from the plane of the cellulosic fibrous structure in both directions. The bilaterally extending protuberances increase the caliper and texture of the consumer product embodied in the cellulosic fibrous structure. In a second embodiment, the protuberances extend outwardly, and are induced by fluid embossing, rather than mechanical embossing. Also disclosed is a fluid embossing process for making such cellulosic fibrous structures.
