Abstract
For treating textile yarns by electrical discharge, the yarn is caused to travel along a path within at least one module. The module has a first and a second electrode confronting each other. A generator is connected to the electrodes to provide a voltage sufficient to strike an arc. The power of the generator and the impedance of the circuit are such that the arc is quenched after striking in a time which is short as compared to the time of rise to the arc striking voltage.
Claims11
A process for treating textile yarns by electric discharge, comprising circulating a yarn through a predetermined location between two electrodes, applying an increasing voltage across said electrodes until an arc is struck between said electrodes, quenching said arc and repeating said arc striking and quenching at a high frequency, the time period between two successive ones of said arcs being greater by at least one order of magnitude than the duration of an individual one of said arcs.
A device for treating textile yarns by electrical discharge, comprising at least one module having a first electrode and a second electrode confronting each other and at a predetermined distance, means for causing the yarn to travel between the electrodes at an arc location and an electric circuit for applying voltage between the electrodes, including a generator constructed to provide across the two electrodes a voltage sufficient to strike an arc between said electrodes in the absence of current flow in the circuit, the power of said generator and the impedance of said circuit being such that the arc is interrupted after striking in a time which is brief with respect to the time of rise to the arc striking voltage.
