Abstract
A method of making a cellulosic web having an elevated absorbency includes forming a nascent web having a random distribution of fiber orientation from a papermaking furnish, non-compactively drying the nascent web to a consistency of from about 30 to about 60 percent, thereafter, transferring the nascent web to a translating transfer surface that is moving at a transfer surface speed, and fabric-creping the nascent web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, the fabric-creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, such that the nascent web is creped from the transfer surface and redistributed on the creping fabric to form a creped wet web. The creped wet web is dried while the web is held in the creping fabric.
