A substrate has an elastomeric film having surfaces and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film. In addition, a substrate has an elastomeric film and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film, and wherein the substrate is essentially free of adhesives and film-based microfibers. A method for making a film/nonwoven composite includes providing an elastomeric film traveling in a machine direction; providing a nonwoven web traveling in the machine direction in face-to-face contact with the film, wherein the nonwoven web includes fibers; and impinging the elastomeric film with hydro jets such that at least some of the fibers become embedded in the film.

Improved skin-adhesive compositions for bonding a substrate, such as an absorbent article, to skin are disclosed. More particularly, the skin-adhesive composition has an improved, yet gentle, adhesion to the skin of a user, while maintaining strong, effective bonding to various inanimate, non-skin substrates. In one embodiment, the skin-adhesive composition can provide one or more skin benefit agents to the user. The skin-adhesive composition may applied to an absorbent article, such as a panty-liner, sanitary napkin, or an incontinence article, for directly adhering the article to the skin of a user.

Absorbent article with a multifunctional acrylate skin-adhesive composition

A thermoplastic polyolefin elastomer film includes a continuous phase that includes a thermoplastic polyolefin elastomer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains, wherein each discrete domain is elongated with a long axis, wherein the axes are aligned in the machine direction (MD) when the film is relaxed, and wherein the axes are aligned in the cross direction (CD) when the film is stretched in the CD. Also, an article includes the thermoplastic polyolefin elastomer film.

Reinforced thermoplastic polyolefin elastomer film

Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.

Toughened polylactic acid fibers

A signal device includes a signal composite made with a coextruded film having at least two layers, a polymer skin layer and a stimulation layer. The stimulation layer includes a cooling agent and a polymer binder. The stimulation layer may be about 50 to 98 percent by weight of the signal composite. The signal device may be used in an absorbent article to provide a cooling sensation after a body-fluid insult has taken place.

Cooling signal device for use in an absorbent article
