Abstract
Multifilament yarns comprising continuous multifilaments each having at least one body section and having extending therefrom along its length at least one wing member, the body section comprising about 25 to about 95% of the total mass of the filament and the wing member comprising about 5 to about 75% of the total mass of filament, the filament being further characterized by a wing-body interaction defined by ##EQU1## where the ratio of the width of said fiber to the wing thickness (L.sub.T /Dmin) is .ltoreq.30. Also disclosed are specific yarns and processes for producing the filaments and yarns. The spun-like character of the fractured yarns of this invention is provided by the wing members extending from and along the body section being intermittently separated from the body section and a fraction of the separated wing members being broken to provide free protruding ends extending from the body section.
