The invention discloses an artificial turf using PET/PBT curved silk yarns. The curved silk yarns are made of PET or PBT or a PET and PBT combined novel material, and the curved silks are curved silk products with a certain curvature, which are obtained after melt extrusion drawing and thermal deformation. After the novel products made of the novel material are applied to the artificial turf, the problems that the artificial turf is poor in aging resistance, poor in thermal stability, poor in flame retardance and the like are solved.
