Abstract (en)

[origin: WO9002222A1] A melt-spinning device comprises an essentially sealed spinning chamber (3) mounted in a gas-tight manner between a spinneret bundle (2) and a yarn suction device (7). The spinning chamber (3) is partially perforated only in the region located 150 to 350 mm from the spinneret bundle. At a winding-off speed of 5500 m/min, the filament produced has a count irregularity less than 0.60 % U.
