发明名称 Non-linting composite gauze material
摘要 A durable hydrophilic substantially non-linting water absorbent drapable composite material useful as wound dressing comprises cellulose fibers coated with hydrophilic polymer. The cellulose fibers may be open weave cotton gauze. The hydrophilic polymer may comprise a polyurethane foam prepolymer, such as a toluene diisocyanate terminated polyethylene glycol, optimally containing a surfactant. Alternatively, the polymer may comprise a polyethylene oxide, a carboxymethyl cellulose, or a polyvinylpyrrolidone. The water to prepolymer weight ratio of the polyurethane embodiment preferably is within the range of from about 6:1 to about 400:1. The hydrophilic polymer may be a polyethylene oxide carboxymethyl cellulose mixture.
