Abstract

The present invention relates to a composite material, which is of particular use in wound treatment, and to a method for producing the same composite material. Said composite material comprises a hydrophilic polyurethane foam material comprising a first polyurethane polymer; a hydrophilic fiber material comprising a second polymer, wherein said second polymer is not a polyurethane polymer and wherein said fiber material is capable of absorbing and retaining a fluid. In the composite material according to the present invention, said first polymer is covalently bonded to said second polymer.
