An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable back-sheet, 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 channel to a second end of the same channel wherein the acquisition distribution system is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system is positioned between said absorbent core and said topsheet such that said spunbond and/or meltblown layers are in direct contact with said absorbent core and said topsheet.
An absorbent article (10, 20, 300, 500, 600) comprising an absorbent core (101, 501, 601) sandwiched between a liquid permeable topsheet (520, 620) and a liquid impermeable backsheet (521, 621), and an acquisition distribution system (201, 522, 622) positioned between said topsheet (520, 620) and said absorbent core (101, 501, 601), wherein the absorbent core (101, 501, 601) 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 (106) substantially free of said absorbent material, wherein said channels (106) have a length extending along a longitudinal axis (48) and the absorbent core (101, 501, 601) has a length extending along said longitudinal axis (48) and wherein the length of said channels (106) is from 10% to 95% of the length of said absorbent core (101, 501, 601) and wherein said channels each follow a substantially continuous path characterized in that the acquisition distribution system (201, 522, 622) is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system (201, 522, 622) is positioned between said absorbent core (101, 501, 601) and said topsheet (520, 620) such that at least a substantial portion of said spunbond layers are in direct contact with said absorbent core (101, 501, 601) and said topsheet (520, 620), and wherein the acquisition distribution system (201, 522, 622) has a wetness retention factor of less than 11 as measured according to the Wetness retention factor test method herein, and wherein the acquisition distribution system (201, 522, 622) comprises synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution system (201, 522, 622), and wherein said acquisition distribution system (201, 522, 622) has a basis weight of from 15 to 40 g/m2.
A method for making an absorbent article comprising one or more channels, the method comprising the steps of:
