Abstract:
1. An absorbent article comprising: an upper, liquid-permeable cover layer, a lower, liquid-impermeable backsheet, an absorbent body arranged between the cover layer and the backsheet, and an air-exchange system arranged between the cover layer and the backsheet comprising at least one air-exchange and at least one air-exchange duct having a longitudinal extension and a cross-sectional area, wherein said at least one air-exchange duct provides two-way air communication between the air-exchange and the surroundings of the absorbent article such that said at least one air-exchange duct defines an air inlet wherein air from the surroundings enters the air-exchange and said at least one air-exchange duct defines an air outlet wherein air exits the air-exchange through said at least one air-exchange duct, wherein the air-exchange is compressible and resilient in all directions, essentially non-absorbent and air-permeable, said air-exchange being in direct contact with the absorption body over a contact surface such that the contact surface is open with regard to air communication between the air exchange and the absorption body; and wherein the air-exchange duct comprises a compressible and resilient, essentially non-absorbent material, and displays air-permeability.
