Abstract (en)
[origin: WO9715706A1] The invention pertains to a process for manufacturing filaments from an optically anisotropic spinning solution in which the spinning solution is extruded through spinning orifices grouped in at least one spinning section and the extrudates are passed through an inert gas and a coagulation bath in succession, with the ratio of the spacing of the spinning orifices to the width of the spinning section being more than 0.15 and less than 0.7, and the width of the spinning section being less than 5 mm. The invention makes it possible to spin a plurality of filaments of good physical properties at a high speed and a comparatively high acid concentration in the coagulant without widespread sticking.
