| description | A wound dressing material 10 comprising a solid substrate 12 having interstitial spaces therein, wherein said interstitial spaces are at least partially filled by hydrophilic polyurethane Foam 14. The solid substrate 12 may be a woven or nonwoven fibrous web or an open-cell foam. The polyurethane foam 14 may be distributed substantially uniformly through the substrate or applied to one side of it. Also provided is a method of making a porous wound dressing material comprising the steps of: providing a sheet of a solid substrate having interstitial spaces therein; applying a fluid polyurethane foam prepolymer mixture to at least one surface of said solid substrate; and curing said prepolymer in contact with said solid substrate. |
