Methods of making disposable absorbent articles are herein. The method includes the steps: obtaining a carrier web; obtaining first absorbent core web and a second absorbent core web; cutting the first absorbent core web in a nesting configuration thereby forming a plurality of discrete first absorbent cores; cutting the second absorbent core web in a nesting configuration thereby forming a plurality of discrete second absorbent cores; joining a discrete second absorbent core to a discrete first absorbent core and to the carrier web, thereby forming a laminate structure web, wherein a leading edge of the discrete first absorbent core is spaced from a leading edge of the discrete second absorbent core in the machine direction; joining a backsheet web to the laminate structure web thereby forming an absorbent article web; and cutting the absorbent article web into a plurality of discrete absorbent articles.

Disposable absorbent articles are disclosed herein along with method of making the same. The disposable absorbent article has a topsheet, a backsheet, and an absorbent system between the topsheet and the backsheet. The absorbent system has a first absorbent core and a second absorbent core which are offset from one another. An adhesive layer is disposed between the first absorbent core and the second absorbent core, at least in part.

Improved absorbent core components including multiple layers configured to enhance fluid handling properties. The layers include absorbent material layers, with or without absorbent material-free lanes. The layers also include nonwoven layers, including air-through nonwovens, bulkified nonwovens, slitted nonwovens, and bulky nonwovens.

An absorbent article comprising a top-surface sheet, a second sheet, and an absorber interposed between the top-surface sheet and the second sheet. The absorbent article allows a body fluid absorbed by the top-surface sheet to move to a non-skin side without deteriorating a soft touch feeling of cotton. The top-surface sheet 3 has a multi-layer structure including a non-heat fusible layer 10 made of a cellulose fiber and arranged on a skin side and a heat-fusible layer 11 made of a heat-fusible fiber and arranged on the non-skin side. The second sheet 6 made of a heat-fusible fiber is arranged on the non-skin side of the top-surface sheet 3. A large number of compressed parts 15 are formed on the non-skin side of the second sheet 6 by integrally recessing the second sheet 6 and the top-surface sheet 3 toward the skin side.

A medical device including a plasma-treated porous substrate that is functionalized to provide a hydrophilic surface, and a process for preparing such a medical device, are disclosed. The method includes plasma treating at least a portion of a surface of a porous substrate with a gas species selected from oxygen, nitrogen, argon, and combination thereof. The gas species is configured to functionalize the surface of the medical device and form a hydrophilic surface.

Particular embodiments of the inventive technology may provide an incontinence pad that includes projection, such as a raised ridge, or a short length projection, that extends from a pad base of and effects application of a force against the urethra of a user (the force, typically upward, that may result from sitting by the user and/or tight fitting shorts and/or pulling a cord attached to the projection); the projection may act to transfer a force from the projection to the urethra. This force may partially or entirely obstruct flow of urine through, or out of the urethra, that might occur otherwise (i.e., without the projection). Another example of the many independent aspects of the inventive technology relates to the provision, as part of an incontinence pad, of a cord that is attached to part of the pad, such as (in only certain embodiments) the aforementioned upward projection.

Disclosed herein are fluff pulp compositions, absorbent articles comprising the fluff pulp compositions, and related methods. The fluff pulp compositions comprise a chemiluminescent system configured to produce visible light upon contact with an aqueous system. Representative absorbent articles include disposable diapers and adult incontinence products. Representative chemiluminescent systems include bioluminescent systems.

[PROBLEM] To improve distribution of adhesive and gas.

[SOLUTION] A nozzle (1) includes a pattern shim (13) having a plurality of first slits (23) and a plurality of second slits (24), an adhesive shim (12) having a plurality of first holes (33), a gas shim (14), a head body (11) having an adhesive outlet (52) and an adhesive distribution groove (51) communicating with the adhesive outlet, and a face plate (15). Adhesive ejection ports are formed at openings of the plurality of first slits, and gas discharge ports are formed at openings of a plurality of second slits in such a manner that the gas discharge ports are located on both sides of each of the adhesive ejection ports. The plurality of first holes (33) communicate with the adhesive distribution groove (51). The plurality of first holes (33) are formed in such a manner that distances of the first holes (33) from the corresponding discharge ejection ports (6) become shorter as distances of the corresponding first holes from the adhesive outlet (52) become longer.

Ultrasonic welding is performed by passing a first sheet layer, a second sheet layer, and an elastic film interposed therebetween in a stretched state in a machine direction between an anvil roll having a large number of protrusions and an ultrasonic horn. The anvil roll includes a region having the protrusions and in the region. A site, in which welding is performed by one ultrasonic horn, has a portion in which an area rate of the protrusions changes in a roll circumferential direction and a roll length direction. A difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll circumferential direction is 4.5% or less, and a difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll length direction is 1.5% or less.
