Patent number: 7846296Abstract: 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: October 16, 2007Date of Patent: December 7, 2010Assignee: Georgia-Pacific Consumer Products LPInventors: Phuong V.

Publication number: 20090065160Abstract: The present invention is generally directed to paper products having great softness and strength and methods of making the paper products. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side.Type: ApplicationFiled: August 8, 2008Publication date: March 12, 2009Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Michael Alan Hermans, Mike T.

Publication number: 20080236772Abstract: A process for making absorbent cellulosic paper products such as sheet for towel, tissue and the like, includes compactively dewatering a nascent web followed by wet belt creping the web at an intermediate consistency of anywhere from about 30 to about 60 percent under conditions operative to redistribute the fiber on the belt, which is preferably a fabric. In preferred embodiments, the web is thereafter adhesively applied to a Yankee dryer using a creping adhesive operative to enable high speed transfer of the web of intermediate consistency such as a poly(vinyl alcohol)/polyamide adhesive. An absorbent sheet so prepared from a papermaking furnish exhibits an absorbency of at least about 5 g/g, a CD stretch of at least about 4 percent, and an MD/CD tensile ratio of less than about 1.1, and also exhibits a maximum CD modulus at a CD strain of less than 1 percent and sustains a CD modulus of at least 50 percent of its maximum CD modulus to a CD strain of at least about 4 percent.Type: ApplicationFiled: June 5, 2008Publication date: October 2, 2008Inventors: Steven L.

Publication number: 20080216977Abstract: Wiping products, such as 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 base web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. The additive composition can improve various properties of the wiping product. For instance, in one embodiment, the additive composition can reduce lint and increase softness.Type: ApplicationFiled: June 14, 2007Publication date: September 11, 2008Applicant: Dow Global Technologies Inc.Inventors: Thomas J.
