Title
(EN) PREPARATION OF HIGH PERFORMANCE FIBER FROM NATURAL FIBER (DATE PALM)
(FR) PRÉPARATION DE FIBRES À HAUTES PERFORMANCES À PARTIR D'UNE FIBRE NATURELLE (PALMIER DATTIER)
Abstract
(EN)
A method (100) of preparing high-performance fibers from a natural fiber source is disclosed. The method (100) includes separating raw fibers from the natural fiber source and dewaxing the separated raw fibers with an alcoholic solution of ethanol and water for a predetermined time at a first predetermined temperature. The method (100) further includes sterilizing the dewaxed fibers with an acidified salt solution at a second predetermined temperature and alkalizing the sterilized fibers with an alkali solution at a third predetermined temperature to generate the high-performance fibers.
(FR)
L'invention concerne un procédé (100) de préparation de fibres à hautes performances à partir d'une source de fibres naturelles. Le procédé (100) comprend la séparation de fibres brutes de la source de fibres naturelles et le déparaffinage des fibres brutes séparées avec une solution alcoolique d'éthanol et d'eau pendant une durée prédéterminée à une première température prédéterminée. Le procédé (100) comprend en outre la stérilisation des fibres déparaffinées avec une solution saline acidifiée à une deuxième température prédéterminée et l'alcalinisation des fibres stérilisées avec une solution alcaline à une troisième température prédéterminée pour générer les fibres à hautes performances.
