28 Claims

1. 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 layer (201, 522, 622) positioned between said topsheet (520, 620) and said absorbent core (101, 501, 601), wherein the absorbent core (101, 501, 601) comprises at least one layer of absorbent material, wherein the absorbent material is selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent core (101, 501, 601) comprises at least one core wrap substrate enclosing said at least one layer of 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 layer (522, 622) is a spunbond nonwoven layer, and wherein said acquisition distribution layer (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 acquisition layer is in direct contact with the core wrap substrate of said absorbent core (101, 501, 601) and said topsheet (520,620), and wherein the acquisition distribution layer (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 layer (522, 622), and wherein said acquisition distribution layer (522, 622) has a basis weight of from 15 to 40 g/m².
