Abstract
A synthetic turf system and method includes turf tufted from monofilament fibers of a thermoplastic polymer where about 1 in about 32 tuft rows comprise at least one antistatic filament per tuft. Each antistatic filament has a first nonconductive polymeric component coextensive with a second non-conductive component. One or more of the antistatic filaments substantially reduces static electrical discharge within the turf. The thermoplastic polymer for each fiber may comprise at least one of nylon, polyethylene, polypropylene, and polyester. Each tuft of the tufted turf may be twisted and each tuft may be slit to form multiple ends. The turf system may comprise stitched turf. Each antistatic filament may comprise a carbon core surrounded by a non-conductive sheath, wherein a ratio of the antistatic filament per number of tuft rows may comprise at least one of 1:2, 1:4, 1:8, and 1:16.
