The invention describes a method for the production of a dressing for the first layer of a bandage and a dressing used for the treatment of burns, bedsores, chronicle and trophic sores. The dressing ensures absolute drainage of wound sepages to the upper layers of the bandage and does not adhere to the wound. The method consists in impregnating a viscose fabric with a polysiloxane, the drying thereof and carbonization in an inert atmosphere. Before carbonization, the fabric undergoes relaxation. After the carbonization, graphitization is carried out. The obtained material undergoes electrochemical treatment then it is cut to produce the dressings. This has a water-absorbing capacity of 100-150 %, a specific surface of 0.7-2.7 m<2>/g, a permeability to air of 70-120 dm<3>/m<2>, an ash content of 0.05-0.10 % and an electric resistance of 0.3-1.0 Ohms. |
