摘要： A low-compaction method of making an absorbent cellulosic web includes: forming a nascent web from a papermaking furnish; dewatering the nascent web to a consistency of from about 10 to about 30 percent on a foraminous forming support traveling at a first speed; rush-transferring the web at a consistency of from 10 to about 30 percent to an open texture fabric traveling at a second speed slower than the first speed of the forming support; further dewatering the web on the impression fabric to a consistency of from about 30 to about 60 percent by way of (i) combining the open texture fabric bearing said web with a fluid distribution membrane and an anti-rewet felt as the three pass through a nip into a pressure chamber defined in part by a plurality of nip rolls, the fluid distribution membrane bearing against the side of the open texture fabric away from the web, with the anti-rewet felt bearing against the web, and (ii) applying a pneumatic pressure gradient from the distributor membrane through the web thereby dewatering the web; and drying the web. Preferably the process includes the steps of selecting the papermaking furnish and controlling the process such that the dried web has a void volume fraction of at least 0.7, a hydraulic diameter in the range of from about 3 to about 20 microns and a Wet Springback Ratio of at least about 0.65. Optionally provided is a high solids fabric crepe in a pressure nip.

摘要： A method of making a fabric-creped absorbent cellulosic sheet is provided which includes dewatering a papermaking furnish and partially drying the web without wet-pressing before applying it to a translating transfer surface moving at a first speed. 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.

摘要： The present invention provides methods of making absorbent cellulosic webs. The methods include the steps of (a) forming a nascent web from a papermaking furnish, (b) non-compactively drying the 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 transfer surface speed, (d) fabric-creping the web from the transfer surface utilizing a creping fabric, the fabric-creping step occurring under pressure in a fabric creping nip, wherein the fabric is traveling at a fabric speed that is slower than the speed of the transfer surface, such that the web is creped from the transfer surface and redistributed on the creping fabric, (e) retaining the web in the creping fabric, and (f) drying the web while it is held in the creping fabric to a consistency of at least about 90 percent.

摘要： The invention relates to a method of making cellulosic absorbent sheet comprising: a) preparing a cellulosic web from an aqueous papermaking furnish, the web being provided with a plurality of fiber-enriched regions with a drawable reticulum having relatively high local basis weight interconnected by way of a plurality of lower basis weight linking regions, the reticulum being further characterized in that it comprises a cohesive fiber matrix capable of increase in void volume upon drawing; b) drying the web while substantially preserving the drawable fiber reticulum; and c) drawing the web. The invention relates also to an absorbent cellulosic web comprising a plurality of fiber-enriched regions of relatively high local basis weight interconnected by a plurality of lower local basis weight regions, characterized in that caliper of the web decreases more slowly than basis weight upon drawing the web, as well as to an absorbent cellulosic web comprising a plurality of fiber-enriched regions of relatively high local basis weight interconnected by a plurality of lower local basis weight regions, characterized in that caliper of the web decreases more slowly than basis weight upon drawing the web.
