ABSTRACT:
Disclosed herein are novel synthetic polymer filaments, and yarns made therefrom, for use in synthetic turf products. The filaments have a rectangular cross-section and the normal directional tendency of such filaments when used in synthetic turf is overcome by folding or texturing the filaments in such a manner that, while the normal advantageous flexibility of the rectangular filament is retained, the directional tendency is removed. When filaments of the invention are used to produce synthetic turfs, the turf surface imparts an essentially non-directional response to objects rolled thereon.
