Abstract
An absorbent structure including a distribution layer and a storage layer is disclosed. The distribution layer has two or more stratums. The two or more stratums include a body facing stratum and a subsequent stratum below the body facing stratum. The density of the subsequent stratum is a fraction of the density of the body facing stratum and the porosity of the subsequent stratum is a multiple of the body facing stratum porosity.
Claims8
An absorbent structure comprising a distribution layer and a storage layer, wherein the distribution layer comprises two or more stratums, wherein the two or more stratums comprises a body facing stratum and a subsequent stratum below the body facing stratum, wherein the density of the subsequent stratum is a fraction of the density of the body facing stratum, and wherein the porosity of the subsequent stratum is a multiple of the body facing stratum porosity;
- and wherein:
- the distribution layer comprises a second subsequent stratum below the subsequent stratum,
- the density of the body facing stratum is higher than the density of the subsequent stratum and the density of the second subsequent stratum;
- and
- wherein the density of the subsequent stratum and the density of the second subsequent stratum are both within 30% of the density of the body facing stratum.
An absorbent structure comprising a distribution layer and a storage layer, wherein the distribution layer comprises two or more stratums, wherein the two or more stratums comprises a body facing stratum and a subsequent stratum below the body facing stratum, wherein the density of the subsequent stratum is a fraction of the density of the body facing stratum, and wherein the porosity of the subsequent stratum is a multiple of the body facing stratum porosity;
- and wherein:
- the distribution layer comprises a second subsequent stratum below the subsequent stratum;
- the permeability of the body facing stratum is lower than the permeability of the subsequent stratum and the permeability of the second subsequent stratum;
- and
- the permeability of the subsequent stratum and the permeability of the second subsequent stratum are both within 50% of the permeability of the body facing stratum.
