  • Melt spinning process to produce filaments
    Patent number: 5976431
    Abstract: Filament stress in a newly spun filament is reduced in that the air friction between the filament and the contiguous air layer is prevented or limited. For this purpose an air current is generated, flowing in the running direction of the yarn at a speed which is the same or approximately the same as the surface speed of the filament. The air current can be guided on to the filament surface through a tube.
