Abstract

La présente invention concerne un procédé de préparation par filage voie humide d'un filament continu à base d'acide hyaluronique sous forme acide libre, notamment soluble dans l'eau. Le procédé de préparation selon l'invention comprend les étapes suivantes : a) préparation d'une solution aqueuse filable d'acide hyaluronique ou d'un sel d'acide hyaluronique, de préférence une solution de hyaluronate de sodium; b) extrusion de ladite solution à travers une filière d'extrusion; c) formation du filament par passage de la solution extrudée dans un bain d'acide acétique concentré, notamment à plus de 80 %, étirage et séchage. L'invention concerne aussi un filament à base d'acide hyaluronique sous forme acide libre, ledit filament présentant des propriétés de gonflement dans l'eau et les liquides physiologiques et étant par ailleurs apte à se solubiliser dans l'eau dans certaines conditions.
