摘要：
A process for dry spinning of synthetic polymers, in particular PAN threads containing more than 85 wt. % acrylonitrile in the PAN (co)polymer, with high spinning chimney capacities of at least 20 kg PAN solid per spinning chimney and hour, using superheated steam as the spinning gas and with in-chimney finishing with water or aqueous finishes.
