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.

Abstract: Process for making producer-colored fibers, yarns, films and related products by extruding from a source, such as from an extruder, a flow of polymer to a spinneret placing in the path of flow between the polymer flow and the spinneret a dye solid or pigment solid having a predetermined shaped surface area, and flowing the polymer into contact against the exposed surface of the dye solid or pigment solid and by such contact dissolving at a predetermined rate a predetermined portion of the dye solid or pigment solid into the polymer flow and coloring the polymer flow for subsequent extrusion from the spinneret as colored filaments.
