Problems solved by technology

However, the "one size fits all" approach often places porous laminates with significant limitations when it comes to elastic properties and functionality in apparel
[0007] Known laminate treatments and their incorporation into a product or garment as a whole are believed to be far from adequately improved relative to specific functional areas or areas of application such as incontinence garments, where laminates are designed for use

Embodiment Construction

[0047]Certain aspects and embodiments of the present invention will be described in terms of disposable absorbent articles, with particular reference to, without limitation and by way of illustration, pant garments such as disposable Diapers, training pants, or bathing suits. However, it will be apparent that aspects of the present invention can also be used to produce other elasticized areas and for other garment or personal care product types such as feminine hygiene products, various incontinence garments, medical garments, and any other disposable Garments that require elasticized areas for ease of production, absorbent or not. Typically, such disposable items are intended for limited use and are not intended to be rinsed or cleaned for reuse. For example, disposable training pants can be discarded after the wearer has soiled them.

[0048] figure 1 is a representative plan view of an absorbent article, such as a disposable diaper 20, in an open or unfolded state. A po...

Abstract

An elastic laminate having an extensible side layer, such as a nonwoven with off-axis perforations, and creating an elastic film layer to provide preferential directions of extension and contraction within the laminate. Elastic laminates are especially useful as waist region panels for disposable pant garments.

Description

Background technique [0001] Disposable garments or limited-use garment panels may be made from nonwoven / elastic material laminates, hereinafter referred to simply as elastic laminates. Depending on the application, some of the desirable properties of these elastic laminates include light weight, good skin feel, external abrasion resistance, and good flexibility. Typically such elastic laminates can be made from at least one nonwoven facing layer laminated to an elastic film or set of filaments. [0002] However, in the past, the ability to properly expand or contract the nonwoven portion of elastic laminates has limited the suitability of such elastic laminates in various personal care product applications. A laminate will only stretch to the extent of its smallest extensible layer. Various techniques have been utilized in the art to overcome this limitation. [0003] For example, in an effort to maximize the extensible range of the nonwoven in elastic film laminates, perfo...
