ABSTRACT:
Electret fibers having improved charge stability are described which are composed of a material which predominantly contains a fiber-forming polymer or polycondensate and 0.01 to 30% by weight (preferably 0.01 to 10, in particular 0.1 to 5%, by weight), based on the weight of the material, of organic or organometallic charge control compounds, as contained in toners for electrophotographic processes, and a process for the production thereof. In addition, textile materials containing these electret fibers are described.
