Publication number: 20090325447Abstract: 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: ApplicationFiled: June 30, 2008Publication date: December 31, 2009Inventors: James Austin, Oomman P.

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.

According to the invention, the elastic laminate has a tacky elastomer core layer and at least one non-blocking outer layer of nonwoven material, applied to the tacky core layer.Type: GrantFiled: May 13, 2005Date of Patent: December 30, 2008Assignee: Nordenia Deutschland Gronau GmbHInventors: Georg Baldauf, Marcus Schönbeck

Patent number: 7452440Abstract: A polyolefin resin drawn sheet 4 is laminated on at least one face of a sheet-form core material 6 having a density of 30 to 300 kgf/m3. At this time, a sheet or film 5 made of a bonding synthetic resin or rubber having a flow starting temperature lower than the thermal deformation temperature of the core material 6 and the melting point of the drawn sheet 4 is interposed between the core material 6 and the drawn sheet 4. The resultant stack product is heated to not less than the flow starting temperature of the synthetic resin or the rubber and not more than the thermal deformation temperature of the core material 6 and the melting point of the drawn sheet 4. At the same time of or after the heating, the stack product is pressed to apply a compression strain of 0.01 to 10% to the core material 6.Type: GrantFiled: February 17, 2006Date of Patent: November 18, 2008Assignee: Sekisui Chemical Co., Ltd.Inventors: Michitaka Tsujimoto, Katsuo Matsuzaka, Koji Yamaguchi, Masashi Okabe, Masanori Hirata, Masafumi Ishiyama
