摘要： 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 first and second film segments are joined at an interface, wherein at the interface a tip of the second segment overlaps the first segment in the cross-direction of the film. The film has a thickness “T” at the tip of the second segment, and the second segment has a thickness “t” at a distance T in the cross direction from the tip of the second segment. The ratio T/t is suitably greater than about 3. The unitary films and laminates thereof are well suited, for example, for use as outer covers in personal care articles.

摘要： A nonwoven substrate includes individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter. The pattern elements can be recessed into and/or extend out of the fiber surface, and the nonwoven substrate can include polypropylene or polyethylene. A disposable absorbent article includes a nonwoven substrate having individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter.

摘要： An absorbent article (10, 110, 210) can include an absorbent assembly (43) including a bodyside liner (28), an outer cover (26, 126, 226), and an absorbent body (35) disposed between the bodyside liner (28) and the outer cover (26, 126, 226). The outer cover (26, 126, 226) can include at least one opaque region (64, 164, 264) and a first indicator region (66, 166, 266). The first indicator region (66, 166, 266) can have a light transmittance that is greater than a light transmittance of the at least one opaque region (64, 164, 264). At least a portion of the first indicator region (66, 166, 266) can be located between the first longitudinal edge (36) of the absorbent body (35) and the first coupling length (45) of the first containment flap (44) in at least the crotch region (16) of the absorbent article (10, 110, 210).

摘要： 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.
摘要翻译： 提供了一种弹性非织造复合体，其包含层压到一个或多个非织造纤维网材料上的弹性膜。 复合材料通过使膜通过辊隙形成，以将膜粘合到非织造纤维网材料上。 与结合形成同时，弹性膜也形成孔。 孔径的尺寸足以提供对复合材料的所需水平的质地，柔软度，手感和/或美学吸引力，而对其弹性性质没有显着的不利影响。 通过选择性地控制层压过程的某些参数，例如膜含量，粘合图案，膜张力程度，粘合条件等，在本发明中实现孔和结合形成。
