Patent number: 8142612Abstract: 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.Type: GrantFiled: January 21, 2009Date of Patent: March 27, 2012Assignee: Georgia-Pacific Consumer Products LPInventors: Frank C.

Publication number: 20100282423Abstract: A method of making a fabric-creped absorbent cellulosic sheet comprising: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber; b) applying the dewatered web having the apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the 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 surface and redistributed on the creping fabric to form a web with a drawable reticulum.Type: ApplicationFiled: July 16, 2010Publication date: November 11, 2010Inventors: Guy H.

Patent number: 7828931Abstract: 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 relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight-linking regions whose fiber orientation is biased along the machine direction between pileated regions interconnected thereby, wherein the sheet exhibits a % CD stretch which is at least about 2.75 times the dry tensile ratio of the sheet. Tensile ratios of from about 0.4 to about 4 are readily achieved.Type: GrantFiled: July 14, 2009Date of Patent: November 9, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: Steven L.

Patent number: 7820008Abstract: An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.Type: GrantFiled: January 8, 2009Date of Patent: October 26, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: Steven L.

Publication number: 20100263817Abstract: Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web as the web is being formed. Alternatively, the additive composition may be topically applied to the web in a post processing operation. For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.Type: ApplicationFiled: July 1, 2010Publication date: October 21, 2010Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Michael Alan Hermans, Michael J.

Patent number: 7807022Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a through drying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the through drying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the through drying fabric when the dried sheet is applied to the surface of the creping cylinder.Type: GrantFiled: July 15, 2008Date of Patent: October 5, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Alan Hermans, Cristina Asensio Mullally, Stephanie Lee Berube, Frank Stephen Hada, Lacey Leigh Hansen, Jeffrey David Mathews

Patent number: 7807023Abstract: Sheet-like products are disclosed containing an additive composition. In accordance with the present disclosure, the additive composition is applied to a creping surface. A base sheet is then pressed against the creping surface for contact with the additive composition. The base sheet is then creped from the creping surface causing the additive composition to transfer to the base sheet. In particular, the additive composition is transferred to the base sheet in amounts greater than about 1% by weight, such as from about 2% to about 50% by weight. The additive composition can comprise, for instance, a thermoplastic polymer resin containing an aqueous dispersion, a lotion, a debonder, a softener, or mixtures thereof.Type: GrantFiled: June 14, 2007Date of Patent: October 5, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas Joseph Dyer, Deborah Joy Nickel, Kenneth John Zwick, Mike T.
