FIELD: spinning.

SUBSTANCE: method comprises treating the fiber made of a belt by moving the fiber over the perforated electrode and under the corona needles of the second electrode. The electrodes are energized with 30-60-kV potential that changes its sign for the opposite one every 1.5 second in the zone of corona discharge. The electrodes are spaced at a distance of 10 mm from the boundaries of the fiber from both sides. The distance between the tips of the corona needles and perforated electrode is 10 mm.

EFFECT: enhanced quality of the fiber and yarn.
