Abstract
The present invention relates to a process for producing fiber aggregate which includes an orientation step of placing the dielectric fluid containing fibers in the form of short fiber, whisker, or a mixture thereof dispersed therein in a space between a pair of electrodes across which an AC voltage is applied, whereby causing individual fibers in the dielectric fluid to electrostatically orient, with one end pointing to one of electrodes and the other end pointing to the other electrode; and an aggregating step of aggregating the electrostatically oriented fibers while keeping the oriented step, whereby producing fiber aggregate in which the fibers are substantially one-dimensionally oriented.
