Patented is a polypropylene fiber comprising at least 100 ppm of a nucleator that does not impart visible color to the fiber. The fiber is textured and exhibits a denier of at least 5 dpf. It demonstrates tensile strength such that the fiber exhibits no appreciable breakage when exposed to spinning of at least about 1000 meters/minute.
