Abstract
A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer may be a spunlace nonwoven and may comprise at least 15% by weight of natural fibers by total weight of the first layer. The first layer may comprise a plurality of protrusions and a plurality of apertures. The first layer and the second layer may be in contact with each other between the majority of the protrusions. The second layer may have a plurality of apertures at least partially aligned with the apertures of the first layer. The first layer may have a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.
