A method of extracting fibers from decorticated plant bast skin involves pre- treating decorticated plant bast skin of a fiber plant with an aqueous solution containing trisodium citrate having a pH in a range of about 8-14 at a temperature of about 90°C or less; and subsequently treating recovered fibers with a protease at alkaline pH.

La présente invention concerne un procédé d'extraction de fibres à partir d'écorce décortiquée qui consiste à prétraiter l'écorce décortiquée d'une plante fibreuse avec une solution aqueuse contenant du citrate trisodique dont le pH se situe entre environ 8 et 14 à une température d'environ 90 °C ou moins, puis traiter les fibres récupérées avec une protéase à un pH alcalin.
