Patent number: 9580869Abstract: A process is disclosed for topically applying additive compositions to planar substrates, such as tissue webs. In one embodiment, the process is designed to apply relatively high viscous compositions to base sheets at high speeds in a manner that prevents the additive composition from penetrating into the sheet. The additive composition having the relatively high viscosity can be applied to the base sheet in one embodiment using an offset gravure printing process. The applicator roll includes a pattern of raised elements. The raised elements define a surface having at least one dimension that is less than 500 microns. The raised elements are also spaced closely together in order to prevent fiber buildup on the roll during relatively fast processing speeds.Type: GrantFiled: December 30, 2010Date of Patent: February 28, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Keyur Desai, Deborah J. Calewarts, Jian Qin, Jeffrey F. Jurena, Stephen Michael Campbell, Donald E. Waldroup

Patent number: 7927322Abstract: The present invention provides an absorbent article having longitudinal direction, a lateral direction, a second portion and a first portion. This absorbent article has a topsheet which has a first major surface that forms a body-facing surface. In addition, the absorbent article has a backsheet which has a second major surface disposed distally from the first major surface. The second major surface of the backsheet forms a garment facing surface of the absorbent article. On the second portion of the top sheet on the first major surface, a body adhesive is applied. In the first portion of the absorbent article, a garment attachment device for attaching the absorbent article to an undergarment of a user is present.Type: GrantFiled: June 13, 2006Date of Patent: April 19, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Bliss Elizabeth Cohen, Stephen Michael Campbell, Garry Roland Woltman

Patent number: 7517579Abstract: A bonded structure including one or more substrates bonded together with a tackified amorphous poly-alpha-olefin adhesive composition. One method of making such a bonded structure is carried out by applying a tackified amorphous poly-alpha-olefin adhesive composition to one or more substrates at a temperature of about 170 degrees Celsius or lower, and joining the substrates to themselves or to one another. The bonded structure has a dynamic peel strength between about 400 and about 1000 grams per 25 millimeters. The bonding efficiency of the bonded structure renders the bonded structure suitable for incorporation into a variety of articles, including personal care products, health/medical products, and household/industrial product, for example.Type: GrantFiled: July 18, 2007Date of Patent: April 14, 2009Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Stephen Michael Campbell, Daniel William Hesse, Richard D.

Patent number: 6902796Abstract: A simplified elastic laminate is made from nonwovens and is especially suitable for side panels of training pant garments or the like. A plurality of thermoplastic adhesive elastomeric fibers are located between first and second facing webs. The fibers have an elastic core and adhesive surfaces. The facing webs, with the elastomeric fibers between them, are calendered together thus adhering the facing webs together via contact adhesion with the elastomeric fibers.Type: GrantFiled: December 28, 2001Date of Patent: June 7, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Charles Morell, James Russell Fitts, Jr., Bryan D.

Patent number: 6835264Abstract: The present invention provides a one or two step method for bonding and creping or double creping a nonwoven web. In the method of the present invention, a nonwoven web is adhered to a creping roll and bonded while on the creping roll. The bonding of the nonwoven adheres the nonwoven to the creping roll in a pattern of the bonding roll. Once creped from the creping roll, the resulting nonwoven web is creped in the pattern of the bonding roll. The creped nonwoven webs of the present invention are useful in a wide variety of application including as wipes, liners, transfer or surge layers, outercovers, other fluid handling materials and looped fastener materials.Type: GrantFiled: December 20, 2001Date of Patent: December 28, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: John Joseph Sayovitz, Gregory Todd Sudduth, Charles Edward Edmundson, Howard Martin Welch, Stephen Michael Campbell, Wendy Marie Takken

Patent number: 6277479Abstract: Breathable microporous films are provided having controlled regional breathability with thick high WVTR regions and thinner low WVTR regions. The zoned breathable microporous films can be made by selectively applying heat and/or pressure to specific regions the microporous film such as by feeding a microporous film through a pair of heated nip rollers with one of the rolls having a raised surface area or by applying a focused stream of hot air. Monolayer microporous films and multilayer films having at least one microporous layer can be treated to impart zoned breathability to the film.Type: GrantFiled: September 30, 1998Date of Patent: August 21, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Stephen Michael Campbell, Howard Martin Welch, Larry Ned Barnett, Jr., Carol Ann Blaney, David Arthur Fell, Sarah Jane Marie Freiburger, William Bela Haffner, Marianne Keevill Leick, Ann Louise McCormack, Douglas H.
