A process and an apparatus for producing hygienic absorbent articles provided with at least one refastenable side seam from a chain of articles being formed having a first elastic sheet and a second elastic sheet, wherein the process and the apparatus are configured to perform operations on one or both of the elastic sheets in a cross direction, that is, with the elastic sheets parallel to the machine direction.

An absorbent article can include a chassis including an absorbent body. The chassis can include a body facing surface. The absorbent article can also include a pair of body exudate containment flaps attached to the body facing surface of the chassis. The containment flaps can include a first portion located in the front portion of the absorbent article and chassis, and a second portion located in the rear portion of the absorbent article and chassis. The second portion of the containment flaps can have one or more properties that are different than one or more properties of the first portion of the containment flaps to reduce the lateral flow of body exudates out the sides of the absorbent article.

Various examples are described for detecting heart rate and respiratory rate by using measurements of light applied to skin through an article. For example, a sensor application obtains a set of measurements of light. The application compensates for a contribution of the article based on one or more known optical properties of the article. The sensor application further determines, from the set of measurements of light, a periodic change in amplitude. The sensor application identifies the periodic change in amplitude as a heart rate having an identical periodicity. The sensor application identifies a respiratory rate as equal to the rate of change of the heart rate.

A disposable diaper having a first sheet of viscose fiber material disposed against a child's skin, an acquisition and diffusion layer (ADL) interposed over top of the first sheet of viscose fiber, a coating layer of tissue fiber interposed over top of the ADL layer, an absorbency core layer interposed over top of the coating layer, a permeable layer of polymer film interposed over top of the absorbency core layer, and a second sheet of viscose fiber material overlaid over top of the permeable polymer film layer, the second sheet functioning as the exterior sheet of the disposable diaper.

A disposable diaper capable of moisturizing the skin of a wearer and suitably maintaining an adhesive force of an end flap portion. A disposable diaper including: an absorber disposed between a liquid pervious top sheet and a liquid impervious back sheet; an end flap portion formed on each side of the absorber in a front-back direction; and a lotion portion extending in the front-back direction at a predetermined interval in a width direction on a body-side surface of the top sheet, wherein in the front-back direction, the lotion portion is disposed in an intermediate portion between a ventral side portion accounting for 20 to 45% of a front-back direction length of the top sheet from a ventral side end of the top sheet and a dorsal side portion accounting for 10 to 35% of the front-back direction length of the top sheet from a dorsal side end of the top sheet.

The present invention relates to a roll-type hook tape for providing a disposable diaper hook member, which is more stably fastened to a loop member which is a counterpart of the hook member, and greatly contributes to manufacturing and commercialization in the form of a roll.

The present invention aims to achieve both a function of diffusing excretions or the like in a longitudinal direction of an absorber and maintenance of adhesion to a wearer in a direction orthogonal to the longitudinal direction. The absorber includes a top sheet (21), a back sheet (22) opposed to the top sheet (21), and an absorbent core (23) extending in a predetermined longitudinal direction between the top sheet (21), and the back sheet (22) and configured to absorb excretions or the like of the wearer. The absorbent core (23) has a plurality of opening portions (23a) each having a shape that opens toward the top sheet (21) and extends in the longitudinal direction and each arranged in the longitudinal direction. An interval (G1) in the longitudinal direction between two opening portions (23a) adjacent to each other among the plurality of opening portions (23a) is set to a dimension equal to or larger than a dimension (D1) in the longitudinal direction of each of the two adjacent opening portions (23a).

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, and the leg gasketing system further including a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket. The disposable absorbent article also includes at least one channel in the absorbent core.
