摘要： A method of making a cellulosic absorbent sheet. A cellulosic web is prepared from an aqueous papermaking furnish. The web is fabric-creped. The fabric-creping step forms a creped web with a drawable reticulum having a plurality of interconnected regions of different local basis weights including at least: (i) a plurality of fiber-enriched regions of a relatively high local basis weight, interconnected by way of (ii) a plurality of lower local basis weight linking regions. The drawable reticulum includes a cohesive fiber matrix capable of increasing in void volume upon drawing. The creped web is dried, while substantially preserving the drawable reticulum, to form a dried web, and the dried web is drawn. The drawing step increases the void volume of the dried web.

摘要： An absorbent sheet of cellulosic fibers includes a mixture of hardwood fibers and softwood fibers arranged in a reticulum having (i) a plurality of pileated fiber enriched regions of a relatively high local basis weight each extending a distance in the cross-machine direction (CD) of the sheet and interconnected by way of (ii) a plurality of lower local basis weight linking regions that each extend a distance in the machine direction (MD) of the sheet and whose fiber orientation is biased along the direction between pileated regions interconnected thereby. The relative basis weight, degree of pileation, hardwood to softwood ratio, fiber length distribution, fiber orientation, and geometry of the reticulum are controlled such that the sheet exhibits a percent CD stretch that is at least about 2.75 times the machine direction to cross-machine direction (MD/CD) dry tensile ratio of the sheet.

摘要： A method of making a fabric-creped absorbent cellulosic sheet includes applying a jet of papermaking furnish to a forming wire, the jet having a jet velocity and the forming wire moving at a forming wire velocity. The papermaking furnish is compactively dewatered to form a nascent web. The nascent web is applied to a transfer surface that is moving at a transfer surface speed. The nascent web is fabric-creped from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric that is traveling at a fabric-creping speed, the fabric-creping speed being slower than the transfer surface speed, and 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 web. The creped web is dried. The jet/wire velocity delta and the fabric-creping step are controlled such that the dry machine direction to cross-machine direction (MD/CD) tensile ratio of the dried web is about at most 1.5.

摘要： The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing.
