Abstract
A method of making a fiber for use in association with an artificial turf system, as well as an artificial turf system having such a fiber. The fiber is made by extruding a fiber, fibrillating the fiber, and storing the fiber, wherein the fiber is not cut longitudinally between the step of extruding the fiber and storing the fiber. After being extruded the fiber may be folded and wrapped with a wrapping yarn.
