Abstract
An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.
Claims17
An absorbent article having a wearer-facing side and an opposite garment-facing side, the article comprising a three-dimensional laminate, wherein the three-dimensional laminate comprises a first layer and a second layer;
- wherein the first layer is intermittently bonded to the second layer by a hot-melt adhesive so that the first layer comprises a plurality of protrusions not bonded to the second layer;
- wherein the three-dimensional laminate is configured to be liquid-permeable;
- and
- wherein the three-dimensional laminate is disposed on the wearer-facing side of the absorbent article;
- and
- wherein the hot-melt adhesive comprises a heterophase polymer having an enthalpy of fusion of at least 10 J/g, as measured according to the Enthalpy of Fusion Measurement Method.
An absorbent article comprising a laminate disposed on a wearer-facing side of the article,
- wherein the laminate comprises a first layer and a second layer;
- wherein the first layer is intermittently bonded to the second layer by a hot-melt adhesive so that the first layer comprises a plurality of protrusions not bonded to the second layer;
- wherein the laminate is configured to be liquid-permeable;
- wherein the laminate forms a liquid-permeable topsheet, such that the laminate is configured to be in contact with a wearer's skin during use of the absorbent article;
- wherein the hot-melt adhesive comprises a heterophase polymer;
- and
- wherein the hot-melt adhesive has a storage modulus higher than 0.3×106 Pa at 37° C., as measured according to the Oscillatory Rheometry Test Method.
