Title (EN) NONWOVEN CELLULOSE FIBER FABRIC WITH INCREASED WATER HOLDING CAPABILITY AND LOW BASIS WEIGHT
(FR) TISSU NON TISSÉ DE FIBRES DE CELLULOSE AYANT UNE CAPACITÉ DE RÉTENTION D'EAU ACCRUE ET UN FAIBLE GRAMMAGE
Abstract:
(EN) It is described a nonwoven cellulose fiber fabric (102) directly manufactured from a lyocell spinning solution (104). The fabric (102) comprises a network of substantially endless fibers (108). The fabric (102) exhibits a water holding capability of at least 850 mass percent. Further, the fabric (102) comprises a mass per unit area which is smaller than 25 gram per square meter. It is further described a method and a device for manufacturing such a fabric (102), a product or composite comprising such a fabric, and various use applications for such a fabric (102).
(FR) L'invention concerne un tissu non tissé de fibre de cellulose (102) fabriqué directement à partir d'une solution de filage de lyocell (104). Le tissu (102) comprend un réseau de fibres essentiellement continues (108). Le tissu (102) présente une capacité de rétention d'eau d'au moins 850 pour cent en masse. En outre, le tissu (102) comprend une masse par unité de surface qui est inférieure à 25 grammes par mètre carré. L'invention concerne en outre un procédé et un dispositif de fabrication d'un tel tissu (102), un produit ou un composite comprenant un tel tissu, et diverses applications d'utilisation pour un tel tissu (102).
