Abstract
A method of making a cellulosic absorbent sheet. A cellulosic web is prepared from an aqueous papermaking furnish. The web is fabric-creped. The fabric-creping step forms a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights including at least: (i) a plurality of fiber-enriched regions of a relatively high local basis weight, interconnected by way of (ii) a plurality of lower local basis weight linking regions. The drawable reticulum includes a cohesive fiber matrix capable of increasing in void volume upon drawing. The creped web is dried, while substantially preserving the drawable reticulum, to form a dried web, and the dried web is drawn. The drawing step increases the void volume of the dried web.
