Publication number: 20100116451Abstract: A paper product with absorbency and moisture strike through resistance is disclosed. More particularly, a multi-ply paper product with improved strike through resistance is disclosed, wherein at least one ply is a wetting resistant ply comprising at least one wetting resistant compound and at least one ply is an absorbent ply possessing greater absorbency than the wetting resistant ply. In addition, a two-ply paper napkin with improved moisture strike through resistance is disclosed, wherein the wetting resistant ply comprises alkyl ketene dimer and the two plies are separately microembossed, glue laminated together in a point to point configuration, and macroembossed with coin edging. Furthermore, a multi-ply paper product with improved strike through resistance is disclosed, wherein a first ply comprises at least one wetting resistant compound and a second ply possesses greater absorbency than the first ply.Type: ApplicationFiled: November 13, 2009Publication date: May 13, 2010Applicant: Georgia-Pacific Consumer Products LPInventors: Dinesh M.

Patent number: 7699959Abstract: Tissues are provided as multi-ply tissue products having greater tactile sensation and resiliency in hand. Improved tissues may have a thickened and reduced density middle layer. The tissues may serve as applicators for chemical agents to be released during use of the tissue. A tissue having an improved tactile impression to the consumer, with enhanced resilience and high external bulk is disclosed. In one embodiment, a multi-ply structure having at least three plies is desirable. A middle or intermediate ply is comprised an increased thickness and a greater bulk is employed. In general, the exterior plies of the tissue are smooth and desirable to the consumer.Type: GrantFiled: March 2, 2009Date of Patent: April 20, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Margaret M.

Patent number: 7662256Abstract: 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: GrantFiled: August 8, 2008Date of Patent: February 16, 2010Inventors: Michael Alan Hermans, Mike T. Goulet, Mark Hassman, Rebecca C. Mohr, Jeffrey J. Johnson, Maurizio Tirimacco, Jeffrey Dean Lindsay

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. Edwards, Guy H. Super, Stephen J. McCullough

Patent number: 7648772Abstract: A sheet of cellulose based material having enhanced strength, particularly the dry strength, substantially unaffected repulpability is disclosed. The sheet of cellulose based materials generally includes a first cellulose based material connected with a second cellulose base material element. The first cellulose based material is formed by separating a portion of the fiber from a furnish, treating the separated portion with a cationic wet strength resin which is allowed to bond to the fiber. The treated fiber is them mixed with the untreated balance of the fiber at some point before the paper machine. The fiber that is separated may be secondary fiber, virgin fiber or combinations thereof. The second cellulose base material element is substantially free from any treatment. The second cellulose base material element may be include substantially all untreated fibers.Type: GrantFiled: June 28, 2005Date of Patent: January 19, 2010Assignee: International Paper Co.Inventors: Terry M. Grant, David W. Park

Patent number: 7641764Abstract: The object of the present invention is to provide a non-woven fabric comprising a glass fiber which has a strength, flexibility and water resistance, has less skin irritancy and a good surface decoration property, and a process for producing the same, more specifically, to provide a non-woven fabric for a gypsum board which is used as a reinforcing material for a gypsum board placed on one side or both sides of the gypsum board, and a process for producing the same. A non-woven fabric for a gypsum board comprising 20 to 60% by weight of a glass fiber, 10 to 50% by weight of an organic fiber and 10 to 50% by weight of a fibrous binder, which contains the organic fiber at least on a gypsum core contact surface, is provided.Type: GrantFiled: December 2, 2005Date of Patent: January 5, 2010Assignee: Mitsubishi Paper Mills LimitedInventors: Mitsuo Yoshida, Kunihiro Tanabe, Hitoshi Fujiki
