Abstract
The invention relates to a process for the production of bifilar fibres and filaments consisting of only one acrylonitrile polymer. The polymer is dissolved in a usual solvent and the resulting solution is divided up into two solution streams. After these solution streams have been brought to different temperatures they are spun by a conventional bifilar spinning technique.
