摘要

Method of making a fabric-creped absorbent cellulosic sheet, the method comprising: (a) applying a jet of papermaking furnish to a forming wire, the difference between a jet velocity and a forming wire velocity being referred to as the jet/wire velocity delta; (b) compactively dewatering the papermaking furnish to form a nascent web; (c) applying the nascent web to a transfer surface; (d) fabric-creping the nascent web from the transfer surface such that the nascent web is redistributed on a creping fabric to form a creped web with a reticulum having a plurality of interconnected regions of different local basis weights, including at least (i) a plurality of fiber enriched regions having a high local basis weight, interconnected by way of (ii) a plurality of lower local basis weight linking regions; (e) drying the creped web; and (f) controlling the jet/wire velocity delta and the fabric-creping step, such that the dry machine direction to cross-machine direction (MD/CD) tensile ratio of the dried web is about at most 1.5.
