ABSTRACT:
A fiber aggregate in which many of the fibers are oriented in the tangent direction of the circumference satisfactorily can be produced by a process and an apparatus according to the present invention. The best feature of the present invention is the following arrangement for a plurality of electrodes used in a process and an apparatus according to the present invention. Vertically extending foil, net or needle-shaped electrodes for orienting the fibers electrostatically are disposed alternately along the circumference of the vertically cylindrical space so as to divide the vertically cylindrical space into equal parts. In addition to this arrangement, the plurality of electrodes may be rotated as well as moved vertically in order not to disturb the fiber aggregation. A fiber aggregate obtained by the present invention has an improved strength and anti-thermal properties.
