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 (R1) and a minor radius (R2). 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 (R1) to the minor radius (R2) defining an exterior modification ratio (R1/R2) of greater than (1).

La présente invention concerne un filament formé d~un polymère synthétique et caractérisé en ce qu~il possède une section transversale à six lobes, dont trois principaux et trois secondaires, et un rayon principal (R1) et un rayon secondaire (R2). Chaque section transversale de lobe possède des parties latérales sensiblement droites s~étendant vers l~extérieur et tangentes à un bout convexe à chaque extrémité. Le rapport du rayon principal (R1) au rayon secondaire (R2) définit un rapport de modification externe (R1/R2) supérieur à 1.
