Abstract

A process of making a wound dressing is suggested, in which a technical conventional viscose solution is mixed with a polysaccharide derivative; the mixture is treated at increased temperatures such that it is thermally coagulated; the coagulate is wetted with a polyalkylene glycol and dried, whereby a particulate structure of the wound dressing is produced.
