Abstract
An absorbent cellulosic sheet includes (i) a plurality of fiber-enriched pileated regions having fibers that are oriented in a direction transverse to a machine direction (MD) of the sheet, and (ii) a plurality of linking regions that link the fiber-enriched regions together. The linking regions have fibers that have an orientation that is offset from the orientation of the fibers in the plurality of fiber-enriched pileated regions.
