ABSTRACT OF THE DISCLOSURE The present invention is a synthetic textile filament having a novel configuration comprising three or more rounded projections or lobes, which provide desired bulk and soil-hiding properties, and two or more substantially flat sides, which provide desired luster. In cross section, the surface of the filament is a continuum of alternating convex and concave arcs of different radii of curvature, as a result of which any distortions in the shape of the filament --e.g., during spinning and/or texturing operations -- do not result in substantial changes in bulk or in luster, which would be manifested as streaks in fabric constructions subsequently prepared there from.
