摘要： An absorbent core for use in an absorbent article, the absorbent core extending in a transversal direction and a longitudinal direction. The absorbent core includes a fluid-permeable top layer, a bottom layer, and a central layer between the top layer and the bottom layer. The central layer may be a high loft fibrous nonwoven layer, in particular having a density of less than about 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles may be blended with the fibers of the central layer, except for one or more longitudinally-extending channels substantially free of superabsorbent polymer particles.

摘要： An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.

摘要： The present disclosure is directed, in part, to an absorbent article including a topsheet including a second substrate disposed at least partially intermediate a first discrete substrate and a third discrete substrate. The first discrete substrate opposes the third discrete substrate about a longitudinal axis of the topsheet. The first discrete substrate and the second discrete substrate are bonded in a first bonding zone about a longitudinal axis of the topsheet. The third discrete substrate and the second discrete substrate are bonded in a second bonding zone about a longitudinal axis of the topsheet. A pair of leg cuffs have free terminal edges and are joined to the topsheet and/or backsheet. The distance between the free terminal edges is not longer than the distance between an inner edge of the first bonding zone and an inner edge of the second bonding zone.

摘要： An absorbent article such as a diaper extending in a longitudinal direction parallel to a longitudinal axis (80′) and a transversal direction (90′) perpendicular to the longitudinal direction and comprising a distribution layer (54) between a topsheet (24) and an absorbent core (28). The distribution layer comprises a fibrous material and a first and second longitudinally-extending channels (86a,b) substantially free of fibrous material. The fibrous material is profiled in the transversal direction so that average basis weight between the channels differs from the average basis weight in the lateral areas outward of the channels by at least 50 g/m2 and/or wherein the distribution layer comprises a first region having a first basis weight (bw1) and a second region having a second basis weight (bw2), wherein the first basis weight and the second basis weight differ by at least 20 g/m2, preferably by at least 50 g/m2, and these regions are present in different areas of the distribution layer but in the same longitudinally extending transversal section. The absorbent core may comprise channel-forming areas (26a,b). The article further comprises a backsheet (25).
