A wound dressing material for treatment of chronic wounds in the form of a freeze-dried or solvent-dried sponge, wherein said material consists of: one or more structural proteins; oxidized cellulose in the form of milled fibers or powder, said oxidized cellulose being complexed to the structural proteins; 0 to 25% of biocompatible polysaccharides other than oxidized cellulose 0 to 20% of water and 0 to 40% of a plasticizer by weight. Also provided is a method of making a wound dressing material comprising the steps of providing an aqueous dispersion of one or more structural proteins; dispersing milled fibers or powder of oxidized cellulose in the aqueous dispersion with mixing; followed by removing water from the aqueous dispersion by freeze drying or solvent drying.
