Abstract

See full text

The invention relates to a process for the production of polymer fibers from polymers dissolved in ionic liquids by means of an air gap spinning process, characterized in that a) a spinning solution that contains an ionic liquid and a dissolved polymer is produced; b) said spinning solution is guided through an extruder before it is divided into fibers via a die; and c) the obtained fibers are guided via an air gap through a coagulation bath.
