摘要: Techniques produce electrostatically charged fibres, and in particular produce an electret fibre construct, where fibres are produced from a plastics and/or natural-origin material, where a polar liquid is atomized using a gaseous pressure medium to produce a treatment aerosol and where the fibres are treated with the treatment aerosol for electrostatic charging, wherein the atomizing is undertaken with a quotient of the volume flow of the polar liquid in litres per second and the positive pressure of the gaseous pressure medium in hectopascals of 0.004 to 0.008.
