Abstract: Presented is a method of producing cellulose-protein fibres from modified cellulose dissolved in aqueous sodium hydroxide, as well as from isolates of rape- and sunflower-derived proteins. Fibres were spun from alkaline cellulose-protein solutions in a coagulation bath containing sulfuric acid and sodium sulfate. Mechanical and morphological properties of the protein-modified cellulose fibres are given. The fibres revealed a high water retention value (WRV) of up to 139%. The concentration and kind of protein are the main factors influencing the stability of the spinning process and the mechanical properties of the resulting fibres. The morphology and structure of the fibres were investigated by means of the SEM and WAXS methods. Also presented are test results of microbiological activity against the Staphylococcus aureus bacterial strain.
