Abstract
A method of making a fabric-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a nascent web having an apparently random distribution of papermaking fiber. The dewatered web is applied to a translating transfer surface that is moving at a transfer surface speed. The web is fabric creped from the transfer surface utilizing a patterned creping fabric. The fabric creping step occurs under pressure in a fabric creping nip defined between the transfer surface and the creping fabric. The creping fabric contacts the transfer surface and applies pressure to the web against the transfer surface such that the fibers of the web are redistributed on the creping fabric to form a web with a drawable reticulum having a plurality of interconnected regions of different local basis weights.
