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.

A process for producing laminated safety glass is disclosed, comprising depositing a film which comprises at least one function layer on a plastic sheet, inserting the sheet between a plurality of further layers, such as two polyvinylbutyral sheets which are in turn enclosed by glass panes, such that the plastic sheet projects beyond the edges of the other layers, clamping the plastic sheet along its projecting sections, and laminating the layers. A clamping device for performing the process and a laminated safety glass produced by the process are also disclosed.
