Patent number: 9011625Abstract: An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing the film through a nip to bond the film to the nonwoven web material(s). Concurrent with bond formation, apertures are also formed in the elastic film. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Aperture and bond formation are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, bonding pattern, degree of film tension, bonding conditions, etc.Type: GrantFiled: January 4, 2013Date of Patent: April 21, 2015Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jose Siqueira, Ann L. McCormack, Norman Brown, Wing-Chak Ng, Howard M. Welch, Margaret G. Latimer

Patent number: 8679992Abstract: An elastic composite formed from a laminate that contains an elastic film and a lightweight nonwoven facing having a low strength in the cross-machine direction (“CD”) is provided. Due to the low strength of the facing, it is desirable that the elastic film have a sufficient thickness and weight to enhance the strength of the resulting composite. Unfortunately, the ability to join an elastic film to such a lightweight nonwoven facing becomes increasingly difficult as the thickness of the film increases. In this regard, the present inventors have discovered that a second laminate may be employed in the elastic composite that is formed from a thermoplastic film and nonwoven facing to impart increased strength to the composite. The film and facing of the second laminate may be formed from the same or different materials than the film and facing of the first laminate. Regardless, the laminates are positioned so that the elastic and thermoplastic films are in a face-to-face relationship.Type: GrantFiled: June 30, 2008Date of Patent: March 25, 2014Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Austin, Oomman P. Thomas, Stephen C. Meyer, Howard M. Welch, Jose A. Siqueira

Patent number: 8603281Abstract: An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction (“CD”) is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing.Type: GrantFiled: June 30, 2008Date of Patent: December 10, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Howard M. Welch, James Austin, Lisa Sanabria, Jose A. Siqueira, Wing-Chak Ng, Bryan D. Haynes, Oomman P. Thomas, Iris V. Schumacher, Christopher Laslie, Stephen C. Meyer

Patent number: 8399368Abstract: A nonwoven web material that contains an elastic component is provided. The elastic component contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic component that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.Type: GrantFiled: October 16, 2007Date of Patent: March 19, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Oomman P.

Patent number: 7585382Abstract: A nonwoven composite that exhibits latent elastic properties is provided. More specifically, latent elasticity may be imparted by blending a thermoplastic elastomer with a polyolefin that is capable of forming semi-crystalline domains among the amorphous elastomeric chains, and then forming a film from the blend. The film is then stretched in one or more directions to orient the amorphous elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the amorphous chains may be held in place by the relatively stiff semi-crystalline olefin domains. Subsequently, the stretched film may be activated (e.g., heated) to shrink the film and provide it with “latent” stretchability. For instance, the stretched film may be heated at or above the softening temperature of the polyolefin to soften the crystalline domains and allow the amorphous chains to return to their unoriented state.Type: GrantFiled: October 31, 2006Date of Patent: September 8, 2009Assignee: Kimberly-Clark worldwide, Inc.Inventors: Janis Wilson Hughes, Tamara Lee Mace, Christian Sanders, Jose Siqueira

Publication number: 20080076315Abstract: An elastic composite that contains an elastic film laminated to one or more nonwoven materials is provided. By selectively controlling the constituents of the composite and the method by which it is formed, the present inventors have discovered that the composite may be resistant to oils and other skin care compositions. More specifically, the elastic film is formed from one or more low density semi-crystalline propylene-based polymers that possess a unique combination of mechanical, elastic, and oil-resistant properties. By using such elastomeric polymers, the resulting elastic film may also be thermally bonded to the nonwoven web material(s) without the need for oil-resistant adhesives. Further, the bonding conditions may be selected so that apertures do not form in the film. In this manner, the resulting composite is impervious to oils or other liquids (e.g., solvents, water, solutions, etc.) and thus acts as a barrier during use.Type: ApplicationFiled: July 6, 2007Publication date: March 27, 2008Inventors: Ann L.
