Abstract
A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer is a spunlace nonwoven and comprises at least 15% by weight of natural fibers by total weight of the first layer. The first layer comprises a plurality of protrusions and a plurality of apertures. The first layer and the second layer are in contact with each other between the plurality of the protrusions. The second layer has a plurality of apertures at least partially aligned with the apertures of the first layer. The first layer has a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.
Claims19
A topsheet for an absorbent article, the topsheet comprising a first layer and a second layer, the second layer being in a face to face relationship with the first layer;
- wherein the first layer is a spunlace nonwoven layer and comprises at least 15% by weight of natural fibers by total weight of the first layer;
- wherein the first layer comprises a plurality of protrusions and a plurality of apertures;
- wherein a majority of the apertures are located between the protrusions;
- wherein the plurality of protrusions and the plurality of apertures impart a three-dimensional shape to the first layer;
- wherein the first layer and the second layer are joined with each other between the plurality of the protrusions;
- wherein the second layer has a plurality of apertures at least partially aligned with the apertures of the first layer;
- wherein the first layer at least partially penetrates the second layer of the topsheet at the majority of the apertures;
- and
- wherein the first layer has a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.
The topsheet according to claim 14, wherein the bonding areas comprise areas of the second layer which coincide with the protrusions of the first layer, and wherein the second layer has no protrusions.
The absorbent article according to claim 17, wherein a width of the second layer of the topsheet in a direction parallel to the transversal centerline is higher than a width of the first layer of the topsheet.
Then absorbent article according to claim 18, comprising gasketing cuffs, wherein the second layer comprises longitudinal edges, and wherein the longitudinal edges of the second layer are bonded to the gasketing cuffs.
A topsheet for an absorbent article, the topsheet comprising a first layer and a second layer, the second layer being in a face to face relationship with the first layer;
- wherein the first layer is a spunlace nonwoven layer and comprises at least 80 by weight of cotton fibers by total weight of the first layer;
- wherein the first layer comprises a plurality of protrusions and a plurality of apertures;
- wherein a majority of the apertures are located between the protrusions;
- wherein the plurality of protrusions and the plurality of apertures impart a three-dimensional shape to the first layer;
- wherein the first layer and the second layer are joined with each other between the plurality of the protrusions;
- wherein the second layer has a plurality of apertures at least partially aligned with the apertures of the first layer;
- wherein the first layer at least partially penetrates the second layer of the topsheet at the majority of the apertures;
- and
- wherein the first layer has a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.
