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.

A topsheet for an absorbent article, the topsheet comprising a first layer and a second 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 at least some of the protrusions are hollow and comprise an inside void volume between the first and second layer;
- 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.
A topsheet for an absorbent article, the topsheet comprising a first layer and a second 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 second layer has a first surface that faces the first layer, and wherein the first surface comprises a flat land area that is aligned with the protrusions in 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.
