Abstract
The present invention provides a synthetic fiber and methods for its use and formation. The present invention may comprise a fiber component that is a twisted bundle comprised of multiple strands of a nonfibrillating monofilament, the degree of twist being greater than about 0.9 turns/inch (about 0.36 turns/cm). The present invention may further comprise another fiber component, discrete from the twisted fiber component, that is fibrillated.
