- A wound dressing containing cellulose-containing material and alginate, wherein the alginate is crosslinked through a polycarboxylic acid ester bond to the celluose of the cellulose-containing material. A method for preparing a wound dressing is disclosed wherein alginate is crosslinked to cellulose through a polycarboxylic acid ester bond, comprising introducing cellulose-containing material into an aqueous solution wherein the aqueous solution contains water, alginate, a crosslinker, optionally an acid catalyst, and optionally polyethylene glycol to form cellulose-containing material wherein alginate is crosslinked to cellulose through a polycarboxylic acid ester bond, drying, and curing. A wound dressing wherein the wound dressing is prepared by the above method.
