摘要：
The present invention relates to a process for the treatment of polyazole films, in which a film is passed at least twice through a trough filled with a liquid, with the film being unrolled from a spool and rolled up on a further spool and the direction of travel of the film is changed during the treatment by altering the direction of rotation of the spools.
