摘要:
An absorbent article comprising a liquid pervious topsheet (300), a liquid impervious backsheet (200), absorbent material positioned between the liquid pervious topsheet and the liquid impervious backsheet, and a bottom distribution assembly between the absorbent material and the liquid impervious backsheet, wherein the absorbent material comprises superabsorbent particles and is arranged such that one or more channels are formed, wherein substantially no absorbent material is present in the one or more channels, wherein the bottom distribution assembly comprises a first layer and a second layer, wherein said first layer has a first density between 20 and 150 kg/m3 and said second layer has a second density between 100 and 400 kg/m3, said second density being higher than the first density, wherein said first layer is closer to the absorbent material than said second layer.
