A continuous filament having a special geometrical cross-section to give controlled fracturability so as to produce free protruding ends, multifilaments of which produce yarns coming within the scope of U.S. Pat. No. 4,245,001; the cross-section of the textile filament having a main body section and one or more wing members connected to the body section, the body section comprising about 25 to about 95% of the total mass of the filament and the wing member or wing members comprising about 5 to about 75% of the total mass of filament, with the filament being further characterized by a wing-body interaction (WBI) defined by <IMAGE> where the ratio of the width of the filament cross-section to the wing member thickness (LT/Dmin) is </=30.
