Abstract (en)
[origin: WO2017162268A1] The invention relates to a method for producing thermally stabilised melt spun fibres in which polyacrylonitrile (PAN) fibres or PAN fibre precursors produced by melt spinning are treated in an aqueous alkaline solution containing additionally a solvent for PAN. The invention also relates to fibres which can be produced according to said method.
