Abstract

The present invention relates to a method for producing a multifilament yarn from a melt of a copolymer of polyacrylicnitrile. The method is characterized in that a multifilament yarn is produced by means of pressing a melt of a copolymer through a spinning nozzle and is subsequently stretched at least tenfold. The present invention further relates to a correspondingly produced multifilament yarn.
