Patent number: 7670457Abstract: A method of making a cellulosic web includes: forming a nascent web from a papermaking furnish, the nascent web having a generally random distribution of papermaking fiber; b) transferring the web having a generally random distribution of papermaking fiber to a translating transfer surface moving at a first speed; drying the web to a consistency of from about 30 to about 60 percent including compactively dewatering the web prior to or concurrently with transfer to the transfer surface; fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric with a patterned creping surface, the fabric creping step occurring 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 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 transfer surfacType: GrantFiled: September 30, 2008Date of Patent: March 2, 2010Assignee: Georgia-Pacific Consumer Products LLCInventors: Frank C. Murray, Greg A. Wendt, Steven L. Edwards, Stephen J. McCullough, Guy H. Super

Patent number: 7662257Abstract: A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking whose fiber orientation is biased along the direction between pileated interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.Type: GrantFiled: April 12, 2006Date of Patent: February 16, 2010Assignee: Georgia-Pacific Consumer Products LLCInventors: Steven L.

Patent number: 7300547Abstract: An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.Type: GrantFiled: November 6, 2003Date of Patent: November 27, 2007Assignee: Georgia-Pacific Consumer Products LLCInventors: Phuong V.
