Abstract (en)
[origin: WO2021151149A1] Disclosed is a process of defibrillating bacterial nanocellulose. The process may comprise providing a pulp comprising bacterial nanocellulose and an alkaline solution and freezing the pulp to form a frozen pulp. The process may comprise allowing the frozen pulp to thaw to form a solution having at least partially defibrillated bacterial nanocellulose fibres. The at least partially defibrillated bacterial nanocellulose fibres may be fully dissolved. The at least partially defibrillated bacterial nanocellulose fibres may be in the form of a non-woven material.
