ABSTRACT:
Process for draw-fracturing yarn the continuous filaments of which each have a cross-section comprising a body section and one or more wing members joined to the body section, the one or more wing members varying up to about twice their minimum thickness along their width, at the junction of the body section and one or more wing members the respective faired surfaces thereof define a radius of concave curvature (Rc) on one side of the cross-section and a generally convex curve located on the other side of the cross-section generally opposite the radius of concave curvature (Rc), the body section comprising about 25 to about 95% of the total mass of the filament and the wing members comprising about 5 to about 75%, the filament being further characterized by a wing-body interaction (WBI) defined by ##STR1## where the ratio of the width of the filament cross-section to the wing member thickness (L.sub.T /Dmin) is .ltoreq.30 the process comprising drawing the yarn to a boiling water shrinkage of .ltoreq.15%, fracturing the wing member portion of the filament utilizing fracturing means, and taking up the yarn.
