| 1. A dressing for a wound, comprising:
a) a hydrophobic liquid permeable layer capable of binding microorganisms, wherein the hydrophobic layer is hydrophobic due
to chemical treatment with a compound containing hydrophobic groups;
b) an absorbent hydrophilic layer; and
c) a cover layer, wherein the hydrophobic layer is adhesively attached to the absorbent hydrophilic layer by a thin layer
of less than 10 g/m2 of a hot-melt adhesive, and the absorbent hydrophilic layer is positioned between the hydrophobic layer and the cover layer,
wherein when the dressing is positioned on the wound, fluids pass through the hydrophobic layer into the absorbent hydrophilic
layer.
