Abstract: The invention relates to a method for the production of a precursor for the production of carbon- and activated carbon fibers according to the wet- or air-gap spinning method, in which a solution of lignin and a fiber-forming polymer in a suitable solvent is extruded through the holes of a spinning nozzle into a coagulation bath, the formed thread is stretched and subsequently treated, dried at an elevated temperature and then wound up. The lignin-containing thread is an economical starting material for the production of carbon- and activated carbon fibers.

Abstract: The present invention relates to a cellulose carbamate spinning solution, the cellulose carbamate being dissolved in at least one ionic liquid. Furthermore, the invention relates to a method for the production of blown films in which a solution of cellulose carbamate in an ionic liquid is extruded into a coagulation bath, and also to the films produced with the method and the use thereof.

Abstract: The present invention relates to a cellulose carbamate spinning solution, the cellulose carbamate being dissolved in an ionic liquid. The invention relates furthermore to a method for the production of nonwovens in which the cellulose carbamate spinning solution is pressed through the holes of a nozzle bar and stretched by a multiple by means of an air flow. The formed fiber curtain is laid on a perforated conveyer belt, washed and dried. Likewise, the invention relates to nonwovens of this type and also the use thereof.

Abstract: The invention relates to a cellulose carbamate spinning solution, cellulose fibres and a method for the production thereof in which a solution of cellulose carbamate in an ionic liquid is pressed through the holes of a spinning nozzle. The shaped fibres are stretched in air and the cellulose carbamate is regenerated in an aqueous bath. Solvent is removed by washing and the fibre is subsequently dried.

Abstract: The invention relates to a method for the production of nonwovens, in which a solution of cellulose carbamate in N-methylmorpholine-N-oxide is forced through the holes of a nozzle beam and is stretched by a multiple by means of an airflow. The fibre curtain which is formed is laid down on a perforated conveyer belt, washed and dried. The invention likewise relates to nonwovens of this type and the use thereof.
