The present invention addresses the problem of providing an absorbent article that has an improved ability to transfer menstrual blood from a liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer. To solve this problem, provided is a sanitary napkin provided with a top sheet, a back sheet and an absorbent body that is interposed between the top sheet and the back sheet, wherein convex portions formed in an excretion orifice contact region of the top sheet are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm.sup.2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000.

The present invention is a roll as may function as an anvil roll that comprises protrusions on its outer surface, that are outwardly or z-directionally oriented arcs of an arc wire such as wavy wire or an axially canted helical coil extending along a length or x-direction, which are pinched perpendicularly to the z- and x-direction. Such anvil rolls may be used to treat materials such as web materials, such as by embossing or bonding these web materials. In a particular application, such rolls may interact with an ultrasonic sonotrode.

An absorbent article is provided with a central elastic material for positioning in a state in which it is extended in the front/rear direction in the outer direction in relation to an absorbent body, and an elastic material cover sheet which abuts the outer direction side surface of the central elastic material. The elastic material cover sheet covers an extension region where the central elastic material is positioned in an extended state, and a non-extension region where the central elastic material is positioned in a non-extended state. An adhesive agent for fixing in the extended state is coated onto the central elastic material of the extension region. An adhesive agent is coated onto at least the non-extension region of the outer direction side surface of the elastic material cover sheet, and the adhesive agent coated onto the outer direction side surface penetrates to the inner direction side surface of the elastic material cover sheet.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. At least some of the three-dimensional deformations may have improved protrusion dimensions after compressive forces are applied on the nonwoven material. In some cases, at least some of the protrusions may have one or more holes therein or completely therethrough. Methods of making the same are also disclosed.

A wound dressing comprising: a backing sheet; a layer of pressure-sensitive adhesive on the backing sheet; an island of absorbent material having smaller area than the backing sheet and applied onto a central region of the backing sheet so as to leave a margin of adhesive- coated backing sheet around the absorbent material, and an apertured wound facing layer applied over the absorbent material and adhered to the backing sheet around said island by said pressure-sensitive adhesive, wherein the apertured wound facing layer comprises an apertured substrate having a coating of a silicone gel on the wound facing surface thereof, the open area of the apertured wound facing layer is from about 5% to about 75%, and the apertured wound facing layer comprises apertures having an open area of from about 2 mm2 to about 100 mm.sup.2.

An absorbent article includes a liquid-permeable topsheet, a liquid impermeable backsheet and an absorbent core positioned intermediate the liquid permeable topsheet and the liquid impermeable backsheet, each layer having a skin-facing side, the absorbent article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis, and the absorbent article defining a front portion having a front edge, a back portion having a back edge and a crotch portion intermediate the front portion and the back portion, wherein the back portion of the absorbent article further includes a transversally extending capture layer, wherein the capture layer includes an outboard transversal edge facing the back edge and two longitudinal edges being sealed to any part of the absorbent article, wherein the capture layer further includes an inboard transversal edge facing the front edge, the inboard transversal edge being unsealed for gathering of feces, wherein the capture layer is positioned to at least partially cover the skin-facing side of the topsheet, wherein the absorbent core includes at least one thickness, wherein at least the back portion of the absorbent article further includes at least one centrally oriented zone in the absorbent core, the zone being at least partially recessed, resulting in the zone having a generally lower thickness in relation to the thickness of surrounding parts of the absorbent core.

An absorbent article that can be a sanitary napkin. The absorbent article comprises a topsheet joined to a backsheet and has an absorbent core material disposed therebetween, the absorbent core material being a fibrous absorbent material exhibiting on one side thereof discrete raised portions. The raised portions define a continuous network of channels, the channels defining a void region adjacent the topsheet of the sanitary napkin.

A wearable article production method for a stretchable sheet having partially weakened stretchability includes a welding step of ultrasonically welding two sheet bodies and an elastic film to each other at plural joints separated from each other in a predetermined transport direction in a region including a predetermined attachment location by transporting a sheet laminate formed by sandwiching the elastic film in an elongated state between the two sheet bodies in the transport direction so that the sheet laminate passes between an anvil roll and an ultrasonic horn to form a stretchable sheet; a weakening step of forming weakened regions, where stretchability of the elastic film is weakened, at least at a part of the attachment location in the stretchable sheet after the welding step; and an attachment step of attaching an absorbent main body to the attachment location so that the absorbent main body overlaps the weakened regions.

In a shaped sheet manufacturing method, it is possible to reliably shape a first sheet even if the tension of the first sheet is reduced at the time of manufacturing the shaped sheet. In a first step, a first sheet is conveyed along an outer peripheral surface of a first roll having a plurality of recessed parts. In a second step, a second sheet is overlapped with the first sheet and conveyed together with the first sheet so that the first and second sheets are held between the recessed parts of the first roll and projection parts of a second roll. In a third step, the first and second sheets having passed between the first roll and the second roll are bonded to each other. In the second step, the tension of the first sheet is made smaller than the tension of the second sheet.
