摘要：
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.
