Patent number: 9724248Abstract: A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/?-olefin copolymer. During formation, the film is stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the propylene/?-olefin copolymer. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state.Type: GrantFiled: January 24, 2014Date of Patent: August 8, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Janis W. Hughes, Glynis A. Walton, Patricia H. Calhoun, Oomman P. Thomas

Patent number: 8377027Abstract: Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member includes a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.Type: GrantFiled: April 29, 2005Date of Patent: February 19, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Janis W. Hughes, Varunesh Sharma, Prasad Shrikrishna Potnis, Gregory Hall, Thomas H. Roessler, Peiguang Zhou, Stephen C. Baumgartner

Publication number: 20100159778Abstract: The present invention is directed to an article suitable for attachment to the skin of a user, the article including a compressible material and a means for attaching the compressible material to skin, wherein the compressible material has Compressibility under a 1.4 kilopascal load greater than about 14 percent, and further wherein the compressible material has an Initial Shear Modulus in a first direction less than about 200 kilopascals.Type: ApplicationFiled: December 24, 2008Publication date: June 24, 2010Inventors: Janis W. Hughes, Bryon P. Day, Russell F. Ross, Lisa M. Sanabria

Patent number: 7722589Abstract: A stretch activated disposable article, such as a wipe or mitt, includes an upper material layer, and a lower material layer joined to the upper material layer such that a space is defined between the material layers. A functional element, for example a fluid composition, is stored in the space between the upper and lower material layers and becomes functional upon being exposed through the upper material layer with use of the article. The upper material layer includes a plurality of materially weakened positions along the surface thereof that are configured to part or separate upon stretching of the upper material layer to expose the functional element through the upper material layer.Type: GrantFiled: August 31, 2005Date of Patent: May 25, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James R. Fitts, Jr., Janis W. Hughes, Bryon P. Day, Ann L. McCormack, Wing-Chak Ng, Varunesh Sharma

Patent number: 7582178Abstract: A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from an elastic film laminated to a nonwoven web facing. Latent elasticity may be imparted to the elastic film through the combination of a thermoplastic elastomer and a polyolefin capable of forming semi-crystalline domains among the amorphous elastomeric chains. More specifically, the elastic film may be stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the polyolefin. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated) to shrink the elastic film and provide it with “latent” stretchability.Type: GrantFiled: November 22, 2006Date of Patent: September 1, 2009Assignee: Kimberly-Clark worldwide, Inc.Inventors: Janis W. Hughes, Wing-Chak Ng, Patricia H. Calhoun, Glynis A. Walton
