  • Patent number: 9676164
    Abstract: As described herein, an extensible sheet material includes a first and a second zone that is separate from the first zone. The first zone exposes a first color or pattern when the extensible sheet material is stretched beyond a first percentage. The second zone exposes a second color or pattern when the extensible sheet material is stretched beyond a second percentage greater than the first percentage. Absorbent articles that include the extensible sheet material are capable of indicating to a wearer when the extensible sheet material has been stretched too little, too much, or just the right amount.

  • Patent number: 9011625
    Abstract: 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.

  • Patent number: 8981178
    Abstract: Unitary films and laminates thereof are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The multi-segment films include a pattern of surface embossments on a surface of the first film segment and a pattern of apertures extending through the second film segment. The first and second segments have different compositions whereby the unitary film includes distinct segments having varied physical properties such as, for example, varied levels of breathability and/or elasticity. The unitary films and laminates thereof are well suited, for example, for use as outer covers in personal care articles.

  • Patent number: 8603281
    Abstract: 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.

  • Patent number: 8226624
    Abstract: Various garments are disclosed which include a body adhesive for attaching the garment to the skin of a wearer. More particularly, the garment can include at least one extensible portion. An adhesive member comprising an adhesive layer and a cover member may be positioned over the extensible portion. The cover member may completely cover the adhesive layer when the extensible portion is in a relaxed condition. When the extensible portion is stretched, however, the cover member may define openings that expose the adhesive layer for adhering the adhesive to a wearer. The garment may comprise, for instance, a diaper, a training pant, a swim pant, a hospital gown, an industrial garment, a glove, a feminine hygiene product, an adult incontinence product, and the like. The adhesive member can be positioned over any suitable extensible portion on the garment.
