A method and an apparatus for detecting foreign fibers in a moving textile material, in particular in moving threads, yarns or slivers, include providing a probe for picking up triboelectric signals from the moving textile material and comparing the output of the probe with a reference value to provide a signal representative of detection of a foreign fiber in the textile material. The apparatus may be used in a card, a drawing bench, a ring spinning machine, an air-jet spinning machine, an open-end spinning machine, a chemical spinning machine, a bobbin winding machine a doubling machine, a combing machine, a bobbin frame, a texturing machine or a loom.
