Abstract

Claims (14)

1 . An absorbent article ( 10 ) comprising an absorbent core ( 12 ) arranged between a liquid permeable topsheet ( 14 ) and a liquid impermeable backsheet ( 16 ), and an acquisition distribution layer ( 18 ) arranged between said topsheet ( 14 ) and said absorbent core ( 12 ), wherein the absorbent core ( 12 ) comprises at least an absorbent material layer, characterized in that the topsheet ( 14 ) consists essentially of an air-through bonded nonwoven layer and is free of spunbond nonwoven layers, in that the acquisition distribution layer ( 18 ) comprises a spunbonded and/or thermocarded nonwoven layer and in that the absorbent core ( 12 ) comprises at least one channel ( 26 ) free of absorbent material.

2 . Absorbent article ( 10 ) according to claim 1 , wherein the spunbonded layer of the acquisition distribution layer ( 18 ) is part of a multi-layer composite sheet additionally comprising a web of meltblown fibers.

3 . Absorbent article ( 10 ) according to claim 1 , wherein the acquisition distribution layer ( 18 ) is free of air-through bonded nonwoven layers.

4 . Absorbent article ( 10 ) according to claim 1 , wherein the acquisition distribution layer ( 18 ) is free of spunlaced nonwoven layers.

5 . Absorbent article ( 10 ) according to claim 1 , wherein each of the topsheet ( 14 ), acquisition distribution layer ( 18 ), and absorbent core ( 12 ) have an air permeability and

wherein the air permeability of the topsheet ( 14 ) is greater than the air permeability of the acquisition distribution layer ( 18 ) and the air permeability of the acquisition distribution layer ( 18 ) is greater than the air permeability of the absorbent core ( 12 ).

6 . Absorbent article ( 10 ) according to claim 5 , wherein the acquisition distribution layer ( 18 ) has an air permeability of from 1 000 L/m 2 /s to 7 000 L/m 2 /s.

7 . Absorbent article ( 10 ) according to claim 5 , wherein the topsheet ( 14 ) has an air permeability of from 4 000 L/m 2 /s to 12 000 L/m 2 /s.

8 . Absorbent article ( 10 ) according to claim 5 , wherein the air permeability of the topsheet ( 14 ) is 1.1 times greater than the air permeability of the acquisition distribution layer ( 18 ) and the air permeability of the acquisition distribution layer ( 18 ) is 1.1 times greater than the air permeability of the absorbent core ( 12 ).

9 . Absorbent article ( 10 ) according to claim 1 , wherein each of the topsheet ( 14 ), acquisition distribution layer ( 18 ), and absorbent core ( 12 ) have a mean flow pore size and

wherein the mean flow pore size of the topsheet ( 14 ) is greater than the mean flow pore size of the acquisition distribution layer ( 18 ) and the mean flow pore size of the acquisition distribution layer ( 18 ) is greater than the mean flow pore size of the absorbent core ( 12 ).

10 . Absorbent article ( 10 ) according to claim 1 , wherein the topsheet air-through bonded nonwoven layer is the most exterior layer of a body-facing side of the absorbent article, adapted to be in contact with the skin when the absorbent article is worn.

11 . Absorbent article ( 10 ) according to claim 1 , wherein the at least one channel ( 26 ) is an interconnected channel forming a substantially continuous path.

12 . Absorbent article ( 10 ) according to claim 1 , wherein each of the topsheet ( 14 ), acquisition distribution layer ( 18 ), and absorbent core ( 12 ) have a density and wherein the density of the topsheet ( 14 ) is lesser than the density of the acquisition distribution layer ( 18 ) and the density of the acquisition distribution layer ( 18 ) is lesser than the density of the absorbent core ( 12 ).
