Abstract
The properties of cellulose diacetate solutions in acetone and acetone–water mixtures at ratios of 95:5, 93.5:7.5 and 90:10 were studied. The optimal concentrations of cellulose diacetate solution for the formation of nanofibers from a mixture of water and acetone with a water content of 7.5 wt% were found. Cellulose diacetate nanofibers were obtained in the form of nonwoven materials with an average nanofiber diameter of 350±10 nm. In order to obtain cellulose nanofibers with a thread diameter of 350–400 nm, cellulose diacetate nanofibers were hydrolyzed in a 0.1 M potassium hydroxide solution.
