Abstract

See full text

Method for fabricating fiber and film products and composites includes: introducing an aqueous gel of nanofibrillar cellulose into a volume of organic extraction agent miscible with water so that the aqueous gel is kept as a separate phase and forms one or several discrete physical entities containing the nanofibrillar cellulose within the phase; changing water with the organic extraction agent in said one or several discrete physical entities of nanofibrillar cellulose; and drying the nanofibrillar cellulose by removing the organic extraction agent from the one or several discrete physical entities of nanofibrillar cellulose. In the method the aqueous gel of nanofibrillar cellulose is introduced into the volume of organic extraction agent in the form of one or several elongated elements which form a fiber-like or ribbon-like or film-like product after drying.
