摘要： This invention relates to an apparatus for false twisting synthetic filament yarns, which apparatus is in the form of an air rotated nozzle having tangential inlet bores and two central outlet bores. The twisting chamber is set at an angle of 2.degree. to 40.degree. to the draw-off direction of the filament. The special advantage of this apparatus according to the invention is that it ensures smooth movement of the filament outside the twisting chamber.

摘要： Hollow acrylonitrile fibres and filaments are prepared by dry spinning the spinning dope through a nozzle having loop-shaped nozzle orifices, the solution having a viscosity equivalent to at least 120 falling ball seconds, measured at 80.degree. C., or at least 75 falling ball seconds, measured at 100.degree. C., wherein the nozzle orifice area of the profiling nozzle is smaller than 0.2 mm.sup.2 and the maximum width of the sides of the loop-shaped nozzle is 0.1 mm and the overlap between the two ends of the sides of the loop-shaped nozzle forms an angle of from 10.degree. to 30.degree. measured from the center of the nozzle and wherein the spinning air acts on the filaments in a transverse direction to the filament take-off and the air direction forms an angle of from 80.degree. to 100.degree. with a straight line passing through the opening between the sides.
