Abstract:This study presents the development of a novel process for producing man-made cellulosic fibers from an ionic liquid solution, the so called Ioncell-F process. It examines the full production chain from efficient dissolution of cellulose in ionic liquid to the suitability of the spun fibers for textile applications. A dry-jet wet spinning process consisting of the extrusion of a polymer solution at mild temperature through a multi-filament spinneret into an aqueous coagulation bath via an air gap was employed for the regeneration of cellulose into filaments. For preparation of the spinning dopes, 1-ethyl-3-methylimidazolium acetate and 1,5-diazabicyclo[4.3.0]non-5-enium acetate were used as solvents for different commercial dissolving pulps.
