Artificial Turf for Simulating Natural Grass

Abstract

An artificial turf simulating natural grass, including: a base fabric, artificial grass yarns tufting on the base fabric and a latex backing on the back of the base fabric. The artificial grass yarns have at least two different forms including a straight form and a curly form, and the straight artificial grass yarns have at least two different colors. Alternatively, the artificial grass yarns have at least a straight form and a curly form tuft on a base fabric and the straight artificial grass yarns are provided with at least two different colors, such that the appearance of the formed artificial turf has a better natural grass simulation effect, and combinations can be made according to specific functional requirements of the application of the artificial turf, thus improving applicability of the artificial turf.
