Abstract
Method and device for producing a flat textile structure in which a melt of a polymer material is changed to the form of fibers with the aid of a spinning rotor. The still sticky fibers are impacted with a mixture of hot gas particles; the particles are then ionized in a high-voltage electrical field for longer duration of the filter effect.
