Abstract

Improved process for obtaining acrylonitrile polymer yarns, characterized in that it comprises the steps of preparing a solution containing said polymer, the expulsion of the resulting solution to a stream, forming it, through a hole with a certain shape, to a gaseous medium in which only a small amount of the solvent used in the preparation of said solution is evaporated from the stream, in the form of a gas; directing said current through said medium to a coagulating bath comprising a precipitator liquid of the polymer and an extractant for the solvent; stretching the article thus formed in the presence of said liquid in order to lose weight thereto; removing the aforementioned article from said coagulant bath; pass it through a second bath and stretch it in the presence of the liquid contained in this second bath to orient the polymer molecules thereof; and then allow the relaxation of the article and consequently its contraction.
