Abstract

L'invention a pour objet un procédé de préparation d'une dispersion aqueuse de fibres de collagène, caractérisé en ce qu'il consiste à tremper la matière de collagène dans une solution aqueuse 0,3 à 1,0 N en NaOH et contenant 10 à 25 % en poids de Na2 SO4 et 0,05 à 0,3 M d'une amine à une température comprise entre 15 et 25 degrés C pendant 5 heures à 10 jours; à laver à l'eau pour éliminer les sels de la matière trempée; à broyer mécaniquement la matière dans un milieu aqueux ayant un pH de 3,5 à 9,5 à une température inférieure à 25 degrés C pour obtenir des faisceaux de fibres de collagène; à tanner les faisceaux de fibres de collagène en les traitant dans une solution d'agent de tannage à une concentration comprise entre 0,005 et 10 % (poids/volume) à une température comprise entre 25 et 35 degrés C pendant 2 à 40 heures; et à broyer mécaniquement et à homogénéiser les faisceaux de fibres tannés à un pH compris entre 2,0 et 4,0 ou 9,0 à 11,0 pour obtenir une dispersion de fibres de collagène d'un diamètre de 4 à 12 microns et d'une longueur comprise entre 2 et 25 mm. La dispersion ainsi obtenue peut être utilisée pour la fabrication de divers articles conformés.
