摘要:
An elastomeric breathable three-dimensional composite material and the process for producing the same are disclosed. A carrier material is supplied onto a top surface of continuous portions of an elastomeric film to form the composite material. A pressure differential is applied to a bottom surface of film for a period of time sufficient for three-dimensional apertured structures to be formed in the film.
摘要:
The present invention pertains to a porous, macroscopically-expanded, three-dimensional, elastomeric web suitable for use in elasticized portions of disposable absorbent articles such as bandages, diapers and pull-up diaper training pants. In a preferred embodiment the web has a continuous first surface and a discontinuous second surface remote from first surface. An elastomeric web of the present invention preferably comprises a formed film having at least two polymeric layers, with at least one of the layers being an elastomer and at least one of the other layers being a substantially less elastomeric skin layer. In a preferred embodiment the elastomeric web exhibits a multiplicity of primary apertures in the first surface of the web, the primary apertures being defined in the plane of the first surface by a continuous network of interconnecting members. Each interconnecting member exhibits an upwardly concave-shaped cross-section along its length. The interconnecting members terminate substantially concurrently with one another to form a secondary aperture in the plane of the second surface of the web. Also disclosed is a method of producing the elastomeric web of the present invention comprising providing a multilayer elastomeric film, supporting the film on a forming structure, and applying a fluid pressure differential across the thickness of the multilayer film. The fluid pressure differential is sufficiently great to cause the multilayer film to conform to the supporting structure and rupture in at least portions of the formed film.

摘要:
An economical method is disclosed for modifying the physical characteristics of a nonwoven fibrous web which involves passing the web between at least one pair of interengaged rolls to incrementally stretch the web, and then withdrawing the incrementally stretched web from between the rolls under tension. A web modified according to the disclosed method has advantageous elongation, extensibility and strength properties, as well as other desirable characteristics. In another aspect, a method is disclosed for forming a composite material by combining a modified nonwoven web with a polymeric film, or an elastic member, which may be liquid impervious yet breathable. In yet other aspect, a method is disclosed for forming a composite material by combining a modified web with a polymeric film which is rendered liquid-impervious yet breathable while the method is performed. The modified nonwoven webs and composite materials made according to the disclosed methods may be advantageously employed in absorbent articles such as disposable diapers.
摘要:
The present invention provides an article to be worn about a wearer including a surface fastening system having a primary direction of load bearing. The surface fastening system has a first surface fastening element and a second surface fastening element. The first fastening element is joined to the article, and the second fastening element is disposed so as to be generally in a face to face relationship with the first fastening element when the surface fastening system is in a fastened configuration. The surface fastening system has a peel resistance in a direction other than the primary direction of load bearing greater than or equal to about 1000 grams.
摘要:
Aspects of the present disclosure involve patterns on substrate surfaces, such as nonwoven webs or fabrics, plastic films, and laminates thereof, that cause the substrate surfaces to exhibit a three-dimensional appearance. In some embodiments, the three-dimensional appearance of the substrate surface resembles protrusions and indentions indicative of threads in woven cloths. The patterns are created by printing a surface of a substrate, as opposed to deforming the substrate such as by embossing. Embodiments of the patterns include a plurality of repeating shapes or macro-units disposed on the substrate surface.
摘要:
An article to be worn about a wearer including an fastening system joined to the article including a receiving member having at least a first receiving fastening element and a second receiving fastening element. The first receiving fastening element is disposed on a flap having a proximal portion joined to the article and a distal portion extending from the proximal portion. The second receiving fastening element is disposed so as to be generally in face to face relationship with the first receiving fastening element when the receiving member is in a closed configuration. An engaging member includes at least a first engaging fastening element and a second engaging fastening element. The first engaging fastening element is engageable with at least the first receiving fastening element and the second engaging fastening element is engageable with at least the second receiving fastening element. The fastening system may be unbalanced; the second flap may be substantially unjoined to the article; the receiving member may have a hinge oriented substantially parallel to a primary direction of load bearing; and/or the fastening system may have a peel resistance in a direction other than the primary direction of load bearing greater than or equal to about 1000 grams.
