ABSTRACT:
The present invention relates to a process for producing fiber aggregate which comprises a dispersion step of dispersing fibers in the form of short fiber, whisker, or a mixture thereof into a dielectric fluid; an orientation step of placing the dielectric fluid containing said fibers dispersed therein in a space between a positive electrode and a negative electrode across which a high voltage is applied, whereby causing individual fibers in the dielectric fluid to electrostatically orient, with one end pointing to the positive electrode and the other end pointing to the negative electrode; and an aggregating step of aggregating the statically oriented fibers while keeping the oriented step, whereby producing fiber aggregate in which said fibers are mostly one-dimensionally oriented. Small amounts of surface active agent in the dielectric liquid promote fiber orientation in addition to dispersing the fibers.
