Abstract:
1. An absorbent sheet of cellulosic fibers, the sheet comprising: a mixture of hardwood fibers and softwood fibers arranged in a reticulum that includes: (i) a plurality of pileated fiber enriched regions having 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 the pileated fiber enriched regions interconnected thereby, wherein the relative basis weight, degree of pileation, ratio of hardwood fibers to softwood fibers, 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.
