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 bulk of the dried web.

摘要： 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.

摘要： A method of making a cellulosic web having an elevated absorbency. The method includes (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, and (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 occurs 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 are selected such that the web is creped from the transfer surface and redistributed on the creping fabric. The method further includes (e) retaining the wet web in the creping fabric, and (f) drying the wet web while it is held in the creping fabric to a consistency of at least about 90 percent. The web has an absorbency of at least about 5 g/g and a cross machine direction (CD) stretch of at least 4 percent.

摘要： An absorbent cellulosic sheet is formed by belt creping a nascent web at a consistency of 30% to 60% utilizing a generally planar perforated polymeric creping belt to form a sheet with fiber-enriched higher basis weight hollow domed regions on one side of the sheet joined by a network of lower local basis weight connecting regions forming a network where upwardly and inwardly inflected consolidated fibrous regions exhibiting CD fiber orientation bias form transition areas between the connecting regions and the domed regions. When formed into roll products, the cellulosic sheets exhibit a surprising combination of bulk, roll firmness, absorbency and softness. The consolidated fibrous regions are preferably saddle shaped and exhibit a matted structure on both their outer and inner surfaces.

The process further includes 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 creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the surface and redistributed on the creping fabric. After creping, the web is dried, preferably with a plurality of can dryers to a consistency of at least about 90 percent while it is held in the creping fabric.
