Abstract. The properties of cellulose diacetate (CDA) solutions in solvent-acetone and acetone-water mixtures in the ratios 9.5:5, 93.5:7.5, and 90:10 were studied. Optimal concentrations of CDA solution were found at which the insoluble water content in acetone is 7.5%, exhibiting properties close to those of Newtonian solutions. CDA nanofibers were obtained in the form of nonwovens with an average diameter of 350–10 nm nanofibers. To obtain cellulose nanofibers, CDA nanofibers were hydrolyzed in a 0.1 M potassium hydroxide solution, and nanocellulose webs with a thread diameter of 350–400 nm and a degree of swelling in the water of 270% were obtained.
