摘要： A method for making an absorbent article comprising an absorbent core comprising one or more channels, the method comprising the steps of: i. providing a first endless moving surface comprising a plurality of molds, each mold comprising a non-porous insert therein, typically said insert having the inverse shape of said channel(s), wherein the molds are in fluid communication with an under-pressure source except for said insert; ii. feeding a first nonwoven web to said first endless moving surface and over one or more said molds; iii. depositing an absorbent material, comprising cellulose fibers and/or superabsorbent polymer particles, over at least a portion of said nonwoven web; iv. removing said absorbent material from areas of the nonwoven web corresponding to said insert; v. applying a second nonwoven web directly or indirectly over the absorbent material, or folding said first nonwoven web, such to sandwich said absorbent material between upper and lower layers of said nonwoven web(s); vi. joining said upper and lower layers together at least in the areas of the nonwoven web(s) corresponding to the insert to form an absorbent core having one or more channels substantially free of absorbent material; vii. optionally joining an acquisition distribution layer to said absorbent core, typically a skin facing surface of said upper layer; viii. optionally laminating said absorbent core and acquisition distribution layer between a liquid pervious topsheet and a liquid impervious backsheet; wherein step vi. comprises the step of selectively applying a first pressure onto the absorbent core, preferably only, in a central portion thereof and a second pressure, preferably only, along peripheral longitudinal side edges thereof miming opposite and parallel to each other and being outboard of said central portion, said central portion corresponding at least to a region of the core comprising said channel(s), and wherein said first and second pressures are successively applied along a machine direction (MD).

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.
