  • Publication number: 20240041671
    Abstract: An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution system positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a chan

  • Publication number: 20240000628
    Abstract: The present invention relates to absorbent articles comprising an absorbent core wherein absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is bonded via a hot melt adhesive to a bottom layer of said core wrap at one or more attachment zones to form one or more channels substantially free of absorbent material. The hot melt adhesive is selected from the group consisting of rubber-based adhesives, adhesives having a viscosity of at least 5500 mPa·s at 150° C. and rubber-based adhesives having a viscosity of at least 5500 mPa·s at 150° C. This may provide exceptionally strong bonding and excellent stability within the channel(s), even in wet state.

  • Publication number: 20230338207
    Abstract: 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 (SAP

  • Publication number: 20230240913
    Abstract: 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 cellulose fibers and/or superabsorbent polymers, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material therein, wherein the absorbent core further comprises an intermediate layer positioned between a top layer of said core wrap and a bottom layer of said core wrap such that said absorbent material is disposed between said top layer and said intermediate layer and/or between said bottom layer and said intermediate layer, and wherein said top layer, said bottom layer, and said intermediate layer are joined together to form one or more channel forming areas substantially free of said absorbent material.

  • Publication number: 20230149224
    Abstract: The present invention relates to an absorbent core (1) for an absorbent article, comprising absorbent material and a continuous channel (4) substantially free of said absorbent material. Said channel (4) comprises at least (i) one longitudinally extending central section (41) coincident with the longitudinal center line (LCL), (ii) four longitudinally extending lateral sections (42), (iii) four diagonally extending diagonal sections (43), and (iv) one transversally extending ending section (44, 44?). A continuous channel made of at least these essential channel sections provides fast absorption, good liquid distribution throughout the entire core, improved fit and comfort and minimizes the risk of leakage.
