Beschreibung
Zusammenfassung:	This invention relates to a poly-trimethylene terephthalate solid core fibrillation resistant synthetic filament, to a spinneret for producing the filament, and to a carpet made therefrom. In a first aspect the present invention is directed toward a solid core, fibrillation-resistant, synthetic polymeric filament having three substantially equal length convex sides. Each side meets an adjacent side through a substantially rounded tip centred on a respective circle of curvature spaced from the axis of the filament by a distance "a". Each rounded tip has a radius substantially equal to a length "b". Figure 1 12C2 12M1 121 12c0 -- b \143 6b 16' 12' \12Rl -12 2 16 2 - 26 12c\|
