A sensor for monitoring wetness in a diaper or other absorbent article includes a housing that attaches to the absorbent article. The sensor may include inner and outer housing portions that capture an edge of the absorbent article between the housings. The sensor may include contacts that electrically connect with a pair of contact strips embedded in the absorbent article. The distance between the embedded strips may vary depending on the size of the absorbent article. The sensor may include multiple pairs of contacts that are spaced apart to match the distance between the contact strips for the variously sized absorbent articles. In this way, depending on the pair of contacts connected to the contact strips, the sensor may indicate the size of the absorbent article.

An absorbent article comprising a first nonwoven material joined to a second nonwoven material by at least one bond area, wherein a polymeric filler composition is disposed within the bond area and the composition comprises at least one polymer selected from the group consisting of polypropylene homopolymers, propylene-ethylene copolymers, and mixtures thereof, wherein the composition is substantially free of tackifiers. It was found that such polymer filler compositions having a Toughness of at least 25 MPa, as measured according to the Extensional Test Method described herein, provide bonds with good resistance to peel creep force.

A membrane for skin comprising a plurality of randomly oriented core-shell nanofibers is provided in the present invention, where each of said core-shell nanofibers comprises at least an active-ingredient-loaded polymeric core and a non-polymeric shell consisting of active ingredients only surrounding the core. Related fabrication method of said membrane is also provided in the present invention.

A single step method for imparting a pattern of apertures in a fibrous nonwoven web is disclosed. The method may include providing a pinned roller bearing a pattern of aperturing pins thereon; providing an opposing roller; arranging the rollers so as to form a nip therebetween, wherein the nip has effectively zero clearance between top surfaces of the pins and outermost surfaces of the opposing roller; providing heating energy to one or both of rollers; rotating the rollers and conveying the nonwoven web through the nip, whereby material constituting fibers of the nonwoven web is at least partially melted and expressed from regions between the top surfaces of the pins and the opposing roller, and accumulates on the web about perimeter edges of the pin top surfaces. Resulting features of the nonwoven web, and products in which it may be incorporated as a component, are also disclosed.

A disposable absorbent article is described herein. The disposable absorbent article includes a topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. At least a portion of the has a plurality of conforming features such that the absorbent article has a blot residual value of less than 30 mg and a bending stiffness of less than 12.

A disposable absorbent article has a topsheet; a backsheet; an absorbent core disposed between the topsheet and the backsheet; and a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and the topsheet. At least a portion of the are depressions, wherein the depressions have a depression centerline bisecting a length and/or width of the depression. A first strut forms a first sidewall of the depression opposite a second sidewall of the depression formed by a second strut, wherein neither of the first strut nor the second strut extend longitudinally and/or laterally beyond the depression centerline by more than 0.75 mm.

A highly extensible nonwoven web is provided. The highly extensible nonwoven web may include continuous multi-component fibers. The continuous multi-component fibers may include polypropylene, wherein the polypropylene has a crystallinity of less than about 41%. The polypropylene may have a melting temperature of less than about 161 C. The highly extensible nonwoven web may define a plurality of apertures. The apertures may be patterned. The highly extensible nonwoven web may form a portion of an absorbent article.

An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.
