The present invention relates to a process for producing hydrophilicized textile sheetlike structures containing synthetic fibres which have a high intitial wettability comprising the steps of: a. forming a textlie sheetlike structure by a textile sheet- forming technique in a conventional manner, b. providing a space, c. transporting the textile sheetlike structure through the space in which the barrier discharge burns, so that the textile sheet-like structure is exposed to the barrier discharge, characterized in that, the corona generator consists essentially of a first resonant circuit, a switch and a second resonant circuit which has an associated high-voltage transformer, the first resonant circuit is a series-tuned circuit which has an inductor and a capacitor which is connected via a switch, a diode and an induce to the primary winding of a high- voltage transformer, and wherein the inductance of the inductor in the first resonant circuit and the switching criterion, which is derived from the voltage across the capacitor, for the switch the second resonant circuit are selected such that the clock frequency of the voltage pulse (which occur in the generator) on the primary winding is less than the eigen frequency of the damped oscillation of the second resonant' circuit.
