Latest Patents

One of her latest patents is focused on a filament based on hyaluronic acid in the form of free acid and the method for obtaining it. This invention relates to a method for preparing a continuous filament through wet spinning, which is notably soluble in water. The preparation method includes several steps: first, preparing a spinnable aqueous solution of hyaluronic acid or a hyaluronic acid salt, preferably sodium hyaluronate. Next, the solution is extruded to an extrusion die, followed by forming the filament by passing the extruded solution into a bath of acetic acid, concentrated to more than 80%, and then drawing and drying the filament. This filament exhibits swelling properties in water and physiological liquids, and it can be solubilized in water under specific conditions.
