Method of making an absorbing wound dressing, comprising the steps of mixing a viscose of technical conventional composition with 50% water soluble carboxylate groups containing polysaccharide derivative in dissolved or solid form selected from the group consisting of sodium carboxymethyl cellulose

Method of making an absorbing wound dressing, comprising the steps of mixing a viscose of technical conventional composition with 50% water soluble carboxylate groups containing polysaccharide derivative in dissolved or solid form selected from the group consisting of sodium carboxymethyl cellulose sodium carboxymethyl starch and sodium alignate, emulsifying said mixture with a dispersion medium which is not mixable with the viscose, then shaping the obtained mixture into specimen by thermal treatment at increased temperatures such that the specimen are coagulated and a particle formation with spherical particles of diameter >10 microns and
