Abstract:
An absorbent cellulosic sheet made by a method that includes forming an aqueous cellulosic web on a portion of a structuring fabric in a papermaking machine, and drying the cellulosic web to form the absorbent cellulosic sheet. The portion of the structuring fabric on which the cellulosic web is formed has a planar volumetric index of at least about 26. The absorbent cellulosic sheet has a caliper of at least about 160 mils/8 sheets and a dry machine direction (MD) to cross machine direction (CD) tensile ratio of less than about 1.0.
