Abstract (en)
[origin: WO2007042311A2] Disclosed are a method and a device for producing staple fibers from melt-spun hollow fibers. In order to be able to produce said staple fibers with as little complexity as possible regarding the equipment, the hollow fibers are guided in a continuous fiber flow from the melt-spinning process to the cutting process, the hollow fibers being extruded through a ring segment-shaped nozzle port that has an outer diameter ranging from 0.2 to 0.8 mm and a maximum hollow proportion of 60 percent, preferably 40 percent, during melt-spinning of a polymer melt.
