The invention relates to a method for producing electrostatic electret fibres, in particular for producing electret fibre formations, in which fibres are produced from synthetic and/or natural materials, a polar liquid is atomized by means of a gaseous pressure medium to produce a treatment aerosol, and the treatment aerosol is dried by means of a drying agent to produce an electrostatic electret fibre, in particular for producing an electret fibre formation. The fibers are treated with a treatment aerosol for electrostatic electrets, the atomization being carried out with the quotient of the volume flow of the polar liquid in liters per hour and the overpressure of the gaseous pressure medium in mbar being 0.004 to 0.008. 本发明涉及一种用于制造静电驻极纤维的方法，静电驻极纤维尤其是用于制造驻极体纤维形成物，在该方法中，由合成材料和/或天然材料生产纤维，借助于气态压力介质使极性液体雾化以制造处理气溶胶，利用处理气溶胶处理纤维以用于静电驻极，其中，在单位为升每小时的极性液体体积流量与单位为毫巴的气态压力介质的过压的商为0.004至0.008的情况下进行雾化。
