Abstract

La présente invention concerne un procédé de production de fibres cellulosiques régénérées à partir d'une solution de filage cellulosique, ledit procédé comprenant les étapes consistant à traiter des déchets cellulosiques recyclés pour éliminer au moins un élément parmi de la lignine, des hémicelluloses et des contaminants des déchets cellulosiques recyclés, ce qui permet d'obtenir un produit intermédiaire cellulosique purifié, à dissoudre le produit intermédiaire cellulosique purifié en une liqueur alcaline pour former une solution de filage cellulosique, à injecter la solution de filage cellulosique dans un bain de coagulation pour former un câble, à laver et étirer le câble dans des conditions alcalines et/ou des conditions acides et à couper le câble pour former des fibres cellulosiques régénérées.
