摘要： Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member comprises a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.

摘要： A stretch activated disposable article, such as a wipe or mitt, includes an upper material layer, and a lower material layer joined to the upper material layer such that a space is defined between the material layers. A functional element, for example a fluid composition, is stored in the space between the upper and lower material layers and becomes functional upon being exposed through the upper material layer with use of the article. The upper material layer includes a plurality of materially weakened positions along the surface thereof that are configured to part or separate upon stretching of the upper material layer to expose the functional element through the upper material layer.

摘要： 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. For instance, the composite may be heated at or above the softening temperature of the polyolefin to soften the crystalline domains and allow the chains to return to their unoriented state. As a result of the present invention, the elastic film may be extended and recover from its unoriented state.

摘要： A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/α-olefin copolymer. During formation, the film is 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 propylene/α-olefin copolymer. 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 at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state. This causes the film to retract, which forms buckles in the nonwoven facing. In this manner, the resulting composite becomes elastic in that it has the ability to stretch and recover due to the "latent" buckle formation in the nonwoven facing.
摘要翻译：提供了具有潜在的弹性特性的非织造复合体。复合材料由层压到非织造织物面向上的多层弹性膜形成。通过使用含有热塑性弹性体的至少一个基层和至少一个含有丙烯/α-烯烃共聚物的表皮层，赋予复合材料潜在弹性。在形成期间，膜在一个或多个方向上拉伸以使弹性体链定向。不期望受理论的限制，本发明人认为链的定向状态可以通过丙烯/α-烯烃共聚物的相对硬的半结晶域保持在适当位置。拉伸的弹性薄膜随后可以松弛并粘合到面向非织造织物以形成复合材料。复合物可以稍后活化（例如，在共聚物的软化点或高于共聚物的软化点加热）以软化结晶域并允许链条恢复到其未取向状态。这导致胶片收缩，这在非织造面部中形成带扣。以这种方式，所得到的复合材料变得弹性，因为它具有由于非织造材料面中的“潜在的”带扣形成而拉伸和恢复的能力。
