ABSTRACT:
An open end spinning rotor wherein the fiber guiding inner surface consists of a wear resistant surface layer of iron boride. The fiber guiding inner surface comprises a fiber sliding surface adjacent to a fiber collecting groove. The fiber collecting groove has a greater frictional resistance than the fiber sliding surface relative to the spinning fibers. This is achieved by means of a special structured surface of the fiber collecting groove. The structure surface of the fiber collecting groove can be created by a roughening of the boronized surface layer by means of a laser for instance, or alternatively, the structure can be created before the boron treatment by mechanical means such as roll pressing.
