    摘要： The present disclosure invention relates to a disposable absorbent article (100) comprising a liquid-pervious topsheet (10), a liquid-impervious backsheet (20) and an absorbent assembly (30) between the topsheet (10) and the backsheet (20). The absorbent assembly (30) comprises an absorbent core (40), an upper core wrap (50) and a lower core wrap (60). The absorbent core (40) comprises at least two cavities (70) substantially free of absorbent material wherein the upper core wrap (50) and the lower core wrap (60) are permanently attached to each other, said cavities (70) being interconnected via at least one connecting line (80) comprising absorbent material. The absorbent core (40) has a first basis weight in the zone out of the cavities (70) and the connecting lines (80) and a second basis weight in the connecting lines (80), the first basis weight being greater than the second basis weight, in the cavities (70). The resulting absorbent assembly (30) may show all together a very good integrity, a very good distribution of fluids and a quick rate of absorption.

    摘要： An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, wherein the absorbent core comprises an absorbent material, said absorbent material comprising a mixture, or blend, of cellulose fibers and superabsorbent polymers, wherein the absorbent core comprises at least a top layer (L1) and a bottom layer (L2) wherein the bottom layer (L2) is positioned between the top layer (L1) and the backsheet, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material therein, wherein the at least top layer (L1) and a bottom layer (L2) are directly stacked one on top of the other to form a contact zone (Zc) where the top layer (L1) directly adjoins to the bottom layer (L2), and wherein the top layer (L1) comprises one or more first superabsorbent polymer grades (SAP1) and the bottom layer (L2) comprises one or more second superabsorbent polymer grades (SAP2), wherein the first superabsorbent polymer grades (SAP1) have an AUL that is greater than the AUL of second superabsorbent polymer grades (SAP2), and wherein the first superabsorbent polymer grades (SAP1) have an AUL, as measured according to the test method herein, of greater than 15 g/g.

    摘要： An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
