Abstract

La présente divulgation concerne un procédé (100) pour obtenir un matériau textile purifié (10) à partir d'un flux textile mixte (MS). Le procédé comprend la discrimination (110a) d'un premier type de matériau textile à l'aide d'un système de spectroscopie proche infrarouge. La déviation (110b) dudit premier type de matériau textile en une première fraction de matériau textile (2). La discrimination (111a) dudit premier type de matériau textile dans la première fraction de matériau textile. La déviation (111b) dudit premier type de matériau textile en une première fraction de matériau textile nettoyée (3). La réduction (120) d'une taille d'article de matériau dans la première fraction de matériau textile nettoyée. Suite à la réduction (120) de la taille de l'élément de matériau, la discrimination (130a) d'un matériau différent du premier type de matériau textile. La déviation (130b) dudit matériau permet ainsi d'obtenir le matériau textile purifié. La présente divulgation concerne en outre un système (1) pour obtenir un matériau textile purifié à partir d'un flux textile mixte.
