Abstract
A topsheet for an absorbent article is provided and has at least a first layer. The first layer comprises at least 15% by weight of natural fibers by total weight of the first layer. The first layer has a plurality of apertures. The first layer comprises land areas between a majority of the apertures. The contact angle on the land areas of the first layer between the majority of the apertures is more than 70° according to the contact angle test method. The topsheet has a run-off of less than 40% according to the run-off test method.
Claims19
A topsheet for an absorbent article, the topsheet comprising at least a first layer, wherein the first layer has a first surface and an opposing second surface and comprises at least 15% by weight of natural fibers by total weight of the first layer;
- wherein the first layer defines a plurality of apertures;
- wherein the first layer comprises land areas between a majority of the apertures;
- wherein a First Surface Land Area Contact Angle on the land areas of the first surface of the first layer between the majority of the apertures is more than 70°, according to the Contact Angle Test Method;
