Abstract
The present invention relates to an apparatus for continuously producing one-dimensionally oriented fiber aggregate in which an orientation vessel includes a case, a supply portion, an orientation portion, a discharge portion, at least one pair of electrodes disposed on the orientation portion of the vessel, and a sheet drive unit. A dielectric fluid in which whiskers and/or short fibers are dispersed is supplied downwardly, and the fibers oriented one-dimensionally by means of high voltage applied across electrodes disposed in an orientation vessel. The sheet drive unit moves a long filter sheet disposed horizontally between the orientation portion and the discharge portion of the orientation vessel to enable the dielectric liquid to pass the filter sheet to the discharge portion of the vessel, and permitting the fibers to aggregate on the sheet.
