摘要： An absorptive wound covering protecting material and a method for preparing an absorptive wound covering protecting material are characterized by solidifying a sponge raw solution containing no reinforcement that is obtained by mixing viscose and crystalline mirabilite as main raw materials, or a sponge raw solution obtained by mixing viscose containing a reinforcement comprising natural fibers having a length of at least 5 mm to 40 mm, and crystalline mirabilite as main raw materials, by performing a heat treatment on the sponge raw solution, and then forming the solidified cellulose sponge in a thickness somewhat greater than a desired thickness, and then forming the cellulose sponge in a sheet form having a desired thickness by compressing the cellulose sponge, and, if required, carboxymethylating hydroxyl groups in a glucose unit constituting a cellulose sponge so that a degree of substitution of the hydroxyl groups is from 0.5 to less than 1.0, and then, forming an incision the cellulose sponge.
