A non-woven fabric suitable for clothing manufacture, comprising a fiber web substantially formed of a continuous filament of a synthetic fiber, wherein a plurality of weakened portions in a form of a scratch or a crack are distributed on the filament constituting at least one surface of the fiber web. Some of the weakened portions are broken to form free ends, some of which are projected from the fabrice surface to form a short fluff, and some of the remaining ends are embedded in the interior of the fiber web and entangled with the filament. The weakened portions of the filament are provided by nipping the fiber web between a pair of rollers, at least one of which has a rough surface formed of a plurality of prominences of hard particles. A punching treatment of the fiber web after the weakened portions has been imparted is effective for breaking the filament to form short fluffs on the fabric surface and for entangling the filaments with each other. A resin treatment before the punching treatment is also favorable.
