ABSTRACT:
A wound dressing comprising at least five layers, the two outer layers comprising a permeable material non-adherent to a wound, below each outer layer there being arranged an absorbent layer each comprising cellulosic fibers, the absorbent layers being separated by a distribution layer comprising at least one of cellulose, carboxymethyl cellulose and a starch polymer. Advantageously the outer layers comprise a nonwoven fleece, a knit or woven fabric, or a perforated plastic sheet of at least one of polypropylene, polyethylene, polyesters, and polyamides, and the periphery of at least one of the outer layers carries a self-adhering adhesive inert to the skin. The entire structure is needled and, if fibrous, the outer layers are lightly thermally bonded so as to be fuzz-free.
