Title (EN) UNIFORMITY AND PRODUCT IMPROVEMENT IN LYOCELL FABRICS WITH HYDRAULIC FLUID TREATMENT
(FR) AMELIORATION DE L'UNIFORMITE ET DES PRODUITS DE TISSUS LYOCELLULAIRES PAR TRAITEMENT PAR FLUIDE HYDRAULIQUE
Abstract:
(EN) A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment, such as with a hydraulic apparatus line (10). The production line includes pre-treatment stations for the fabric (12), such as roll feed table (46), unwind station (14), scray (16), edge guide (18), saturator (20), washer or scouring stations (22, 24) and pre-tenter station (26). Following the pre-treatment, the fabric is advanced through hydraulic treatment modules (30, 32) which include fluid curtain (34), columnar fluid jets (35), endless conveyor (48) driven by rollers (50), planar support members (52, 54) and spaced manifolds (56). The fabric is then advanced to post-treatment stations which include weft straighteners (40, 42), padder station (36), vacuum extractor station (44), frame dryer (38), inspection stations (72, 74), fabric accumulator (76), operator inspection station (78), and fabric wind-up station (80).
(FR) Un fini micro-fibrillé du type suède est conféré à des tissus cellulosiques pouvant être fibrillés par un traitement hydraulique au large, sur une ligne d'appareil hydraulique (10), par exemple. La ligne de production comprend des postes de pré-traitement du tissu (12), tels qu'une table d'alimentation par rouleaux (46), un poste de déroulage (16), un poste de dépose (16), un dispositif de guidage des bords (18), un saturateur (20), des postes de lavage ou désensimage (22, 24) et un poste de pré-étirage (26). Après le pré-traitement, le tissu passe par des modules de traitement hydraulique (30, 32) qui comprennent un rideau de fluide (34), des jets de fluide en colonnes (35), un convoyeur sans fin (48) entraîné par des rouleaux (50), des éléments de support plans (52, 54) et des collecteurs espacés (56). Le tissu avance ensuite jusqu'aux postes de post-traitement qui comprennent des redresseurs de trames (40, 42), un foulard (36), un poste d'extraction à vide (44), un sécheur (38), des postes de contrôle (72, 74), un dispositif d'accumulation du tissu (76), un poste de contrôle par opérateur (78) et un poste d'enroulage du tissu (80).
