Zusammenfassung:	The present invention provides an improved process for manufacturing a polypropylene monofilament suture comprising aging a polypropylene filament that has been drawn in two separate drawing steps in the range of from about 4X to about 8.5X for less than two days then annealing the polypropylene filament to provide a polypropylene suture. La presente invencion provee un procedimiento mejorado para fabricar una sutura de monofilamento de polipropileno, y consiste en dejar reposar por menos de dos días un filamento de polipropileno que ha sido estirado en dos pasos separados de estiramiento en la escala de aproximadamente 4X a aproximadamente 8.5X, recociendo después el filamento de polipropileno para proveer una sutura de polipropileno.
