Abstract
A method of making a fabric-creped absorbent cellulosic sheet includes forming a nascent web from a papermaking furnish, the nascent web having a generally random distribution of papermaking fiber, transferring the nascent web having the generally random distribution of papermaking fiber to a translating transfer surface that is moving at a transfer surface speed, drying the web, to a consistency of from about 30 to about 60 percent, including compactively dewatering the web prior to or concurrently with transfer of the web to the transfer surface, fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric with a patterned creping surface, the fabric-creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, the web being creped from the transfer surface and redistributed on the creping fabric.
