Abstract of the Disclosure The synthetic pulp-like material of the present invention is a fibrillated fibrous material composed mainly of hydrophobic polymer and a hydrophilic polymer, in which the hydrophilic polymer exists in the shape of irregular islands when viewed in cross section taken at a right angle to the fiber axis. The hydrophilic polymer is arranged as continuous or intermittent striae in the direction of the fiber axis, in a substantially greater part of said fibrous material, the ratio of the transverse dimension (?1) to the longitudinal dimension (?2), (?1/?2) is within the range of about 1-10 and the longitudinal dimension (?2) does not exceed 10 microns. This synthetic pulp-like material, useful for making synthetic paper, is produced by emulsion flash-spinning, in which a separate fluid is introduced into a nozzle upon discharging an emulsion containing polymers.
