Abstract:
1. A method of making a cellulosic web having elevated absorbency, the method comprising: (a) forming a nascent web having an apparently random distribution of fiber orientation from a papermaking furnish; (b) non-compactively drying the nascent web to a consistency of from about 30 to about 60 percent; (c) thereafter, transferring the web to a translating transfer surface that is moving at a first speed; (d) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, the creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, wherein the fabric is traveling at a second speed that is slower than the speed of the transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping fabric, (e) retaining the wet web in the creping fabric; and (f) drying the wet web, while the wet web is held in the creping fabric, to a consistency of at least about 90 percent, wherein the web has an absorbency of at least about 5 g/g and a cross machine direction (CD) stretch of at least 4 percent.
