<p>A wound dressing combining a graduated density felt (1) with an absorbent fibre layer (2) in order that the aggressive absorption of the absorbent layer (2) may be regulated to acceptable rates for wound dressing usage and to ensure potentially irritative alginate absorbent fibres are isolated from the wound site. The graduated density felt (1) acts as a regulating or gate layer for the absorbent fibre layer (2) and so limits the rate that exudate from a wound that can pass to the absorbent fibre layer (2). Furthermore, the regulating layer (1) effectively spreads the exudate to give a conical transmission profile enhancing wound dressing performance.</p> |
