ABSTRACT:
The fiber sliding surface and the fiber collecting groove of an open-end spinning rotor are provided with hard particles embedded therein. After a certain length of operation time of the spinning rotor, the particles in the fiber collecting groove have a larger particle size than the particles in the fiber sliding surface. Thus it is ensured that the fiber collecting groove has a better "grip effect" relative to the fibers to be spun than the smoother fiber sliding surface.
