摘要： A disposable absorbent article having a topsheet, a backsheet, and an absorbent core structure disposed between the topsheet and backsheet. The absorbent core structure includes an upper nonwoven layer comprising polymer fibers; a lower nonwoven layer comprising polymer fibers; and an inner core layer disposed between the upper and lower nonwoven layers. The inner core layer may include from about 50% to about 85% cellulosic fibers, by weight of the inner core layer, and from about 15% to about 50% superabsorbent particles, by weight of the inner core layer. The absorbent article may have a CD Dry Bending Stiffness between about 10 N mm2 to about 30 N·mm2 as measured according to the Wet and Dry CD and MD 3 Point Bend Method and a 5th Cycle Wet % Recovery of between about 29% and about 40% as measured according to the Wet and Dry Bunched Compression Method.

摘要： A mandrel suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel has a mandrel shaft with a longitudinal axis, a plurality of mandrel arms extending from the mandrel shaft, and at least one expansion element disposed upon one of the mandrel arms. The mandrel shaft is capable of rotating about the longitudinal axis. Each of the mandrel arms is disposed and rotatable about the longitudinal axis. The at least one expansion element is expandable radially away from the mandrel arm relative to the longitudinal axis. The convolutely wound web material is disposable about each of the mandrel arms. Further, the at least one expansion element is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms.

摘要： 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.

摘要： A disposable absorbent article having a topsheet, a backsheet, and an absorbent core structure disposed therebetween. The absorbent core structure includes an upper nonwoven layer comprising polymer fibers, a lower nonwoven layer comprising polymer fibers, and an inner core layer disposed between the upper and lower nonwoven layers. The inner core layer includes from about 50% to about 85% cellulosic fibers, by weight of the inner core layer, and superabsorbent particles. The inner core layer is contained within the nonwoven layers by substantially sealing at least a left side region and a right side region of the upper and lower nonwoven layers. The absorbent article has a CD Dry Bending Stiffness between about 10 to about 30 N·mm2 as measured according to the Wet and Dry CD and MD 3 Point Bend Method and a Total IFF+SFF value of between about 20 and about 200 mg as measuring according to the Acquisition Time and Rewet Method.

摘要： A feminine hygiene pad is disclosed. The disclosed pad has a longitudinal axis and a lateral axis, and has a topsheet including a nonwoven web, a backsheet, and an absorbent structure between the topsheet and the backsheet. The nonwoven web includes at least a first arrangement of first apertures having a first average size, and a second arrangement of second apertures having a second average size. The first average size is greater than the second average size. The first arrangement occupies a rectangular central region centered about the longitudinal axis and straddling the lateral axis. The first average size is 0.4 mm2 to 0.6 mm2; and the central region has an Average Percent Open Area of 1 to 12 percent. The second arrangement occupies one or more regions laterally and/or longitudinally outboard of the central region, and the second average size is 0.05 mm2 to 0.2 mm2.
