ABSTRACT:
A wound dressing that efficiently absorbs fluid from fluid exuding wounds and can easily be released from the wound without disrupting the wound surface and a process for its manufacture is provided. The dressing comprises a layer of film bonded to a fibrous absorbent web containing a mixture of a particulate superabsorbent and a hydrocolloid. The fibrous absorbent web has a glazed exposed surface wherein the fibers comprising the glazed exposed surface are substantially fused to each other. The glazed exposed surface has a multiplicity of particles comprising a mixture of an adhesive and a hydrocolloid distributed throughout and adherent to the surface. Preferably about 25% to about 50% of the surface is left uncovered by particles comprising the adhesive and the hydrocolloid to enable more efficient transfer of wound exudate into the fibrous absorbent web while the hydrocolloid contained in the particles of adhesive facilitates release of the dressing from the wound without disrupting the surface. A selvage encompasses the wound dressing, with the selvage comprising fibers of the fibrous absorbent web that are substantially fused to each other and to the layer of film bonded to the fibrous absorbent web.
