Solubility of Bacterial Cellulose and Its Structural Properties

ABSTRACT

Based on experiments conducted, it has been found that bacterial cellulose,
like spruce cellulose, is soluble in an aqueous NaOH solution with the concentration
of 8.5% at a temperature of 057C if the polymerization degree of the cellulose does not
exceed 400. When 1% of urea is added to the NaOH solution, the solubility of cellulose
increases; and, in this solvent, bacterial cellulose may be dissolved so long as its polymerization degree is below 560. The results of these experiments are of great practical
importance since they point to the possibility of the preparation of cellulose spinning
solutions suitable for fiber formation.
