Abstract

Improvements in the process for obtaining acrylonitrile polymer yarns, object of the main patent, characterized by comprising the steps of preparing a solution containing said polymer; of ejecting the resulting solution in the form of a current by driving it through a shaped hole, into a gaseous medium capable of evaporating, in which only a small amount of the solvent used in the preparation is evaporated from the stream. of said solution; of directing said current through said medium, at a short distance, and into a coagulation bath containing a precipitating liquid for the polymer and solvent extractor; of removing the thus formed article from the coagulation bath; to tighten said article between the point of expulsion and that of withdrawal, to attenuate it; of passing the article through a second liquid and of tensing it in the presence of said second liquid to orient the polymer molecules; and after allowing the article to relax and therefore contract.
