Abstract:
1. A method of making a belt-creped absorbent cellulosic sheet, the method comprising: (a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber; (b) applying the nascent web having the apparently random fiber distribution to a translating transfer surface that is moving at a transfer surface speed; (c) belt-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping belt, the belt-creping step occurring under a pressure of at least 20 pounds per linear inch in a belt creping nip defined between the transfer surface and the creping belt, the creping belt traveling at a belt speed that is slower than the speed of the transfer surface, and the web being creped from the transfer surface and redistributed on the creping belt to form a web with a reticulum having a plurality of interconnected regions of different local basis weights, including at least (i) a plurality of fiber enriched pileated of having a high local basis weight, interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased toward the direction between the fiber enriched pileated regions; and (d) drying the web to form a dried web.
