Abstract
An absorbent sheet of cellulosic fibers includes a mixture of hardwood fibers and softwood fibers arranged in a reticulum having (i) a plurality of pileated fiber enriched regions of a relatively high local basis weight each extending a distance in the cross-machine direction (CD) of the sheet and interconnected by way of (ii) a plurality of lower local basis weight linking regions that each extend a distance in the machine direction (MD) of the sheet and whose fiber orientation is biased along the direction between pileated regions interconnected thereby. The relative basis weight, degree of pileation, hardwood to softwood ratio, fiber length distribution, fiber orientation, and geometry of the reticulum are controlled such that the sheet exhibits a percent CD stretch that is at least about 2.75 times the machine direction to cross-machine direction (MD/CD) dry tensile ratio of the sheet.
