摘要： In the production of fibers by blast drawing in which primary filaments are produced from a liquid stream, reduced to fibers and drawn on passing through a draw nozzle by drawing gas streams flowing substantially parallel to the primary filaments, the improvement which comprises surrounding the drawing gas streams over at least part of their length and inside the draw nozzle in the direction of flow by parallel boundary gas streams having at most the same flow velocity as the drawing gas streams. Advantageously the parallel boundary gas streams are formed by that part of a circular flow produced on both sides of the drawing gas stream which is in contact with the drawing gas stream, the flow velocity of the parallel boundary gas streams amounts to between about 60 and 80% of the velocity of the drawing gas streams, the drawing gas streams having a velocity of from about 360 to 500 m/s, the volume flow of the parallel boundary gas streams amounting to between about 20 and 60% of the volume flow of the inlet stream, the drawing gas streams and the parallel boundary gas streams being driven by a pressure gradient generated by power jets in the draw nozzle. A corresponding novel draw nozzle is provided. The inner walls of the nozzle do not undergo the erosive/abrasive wear characteristic of other draw nozzles.
