Title (EN) NONWOVEN CELLULOSE FIBER FABRIC WITH TAILORED LIQUID WICKING CAPABILITY
(FR) TISSU EN FIBRES DE CELLULOSE NON TISSÉES À CAPACITÉ DE CAPILLARITÉ DE LIQUIDE ADAPTÉE
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) is characterized by at least one of the following features: (i) a rate of liquid spread is at least 3000 mm2 within 5 minutes; (ii) a water absorbing capability is characterized by a wicking speed of at least 0.25 gram water per 1 gram fabric and 1 second. 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 en fibres de cellulose non tissées (102) fabriqué directement à partir d'une solution de filage de lyocell (104). Le tissu (102) comprend un réseau de fibres sensiblement sans fin (108). Le tissu (102) est caractérisé par au moins l'une des caractéristiques suivantes : (i) une vitesse d'étalement de liquide est supérieure ou égale à 3 000 mm2 en 5 minutes; (ii) une capacité d'absorption d'eau caractérisée par une vitesse de capillarité supérieure ou égale à 0,25 gramme d'eau par gramme de tissu et par seconde. 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).
