Total Claims: 11
Claim 1
Independent Claim
93 words
An hygienic absorbent pad which comprises an absorbent core (2) and a layer of liquid pervious material adapted to promote the spread of fluid in one direction within the absorbent pad characterised in that the layer of liquid pervious material is a plastics net (3) which comprises a plurality of ribs in one direction interconnected by a plurality of fibrillated strands in a transverse direction and said layer is positioned within the absorbent core or adjacent to the non-body facing surface of the absorbent core, the direction of ribs defining the one direction.
