<p>A filament comprising a synthetic polymer and characterized by a hexalobal cross-section having three major lobes and three minor lobes, and a major radius (R<SUB>1</SUB>) and a minor radius (R<SUB>2</SUB>). Each lobal cross-section having essentially straight side portions extending outwardly and tangent to a convex tip at each end. The ratio of the major radius (R<SUB>1</SUB>) to the minor radius (R<SUB>2</SUB>) defining an exterior modification ratio (R<SUB>1</SUB>/R<SUB>2</SUB>) of greater than 1.</p> |
