Abstract
A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a translating transfer surface and is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping fabric travels at a fabric speed that is slower than the speed of the transfer surface. The nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights. The creped web is dried to form a dried web, and the dried web is drawn. The drawing step includes drawing the dried web between a first draw roll and a second draw roll.
