Abstract
A process for producing fiber aggregate which comprises the steps of coating a conductive material which is insoluble in a dielectric fluid on the surface of fibers; dispersing the fibers into the dielectric fluid to obtain a fiber suspended fluid; introducing the fiber suspended fluid into an electric field which is generated in a space between a positive electrode and a negative electrode, whereby causing individual fibers to electrostatically and one-dimensionally orient; and aggregating the oriented fibers. The conductive material contributes to charge-transfer, and it causes the fibers in the electric filed to orient stably.
