Artificial turf and method for preparing the same

An artificial turf, comprising a base mat, artificial grass fibers clustered on the base mat and a backing layer adhered to the back side of the base mat, wherein the artificial grass fiber comprises a straight fiber and a curve fiber, and the material of the straight fiber is Polyamide, and the material of the curve fiber is at least one selected from Polyamide and Polypropylene, wherein the turf density of the artificial grass fiber is from 7560 to 25200 tufts/m2, the straight fiber has a length of 12 to 60 mm, and a single-fiber denier of 500 to 2000 D;

• and the curve fiber has a natural length of 8 to 30 mm and a single-fiber denier of 250 to 1100 D;
• wherein the straight fiber is made from a material comprising the following raw materials parts by mass:
• Polyamide
• 70 to 90
• parts;
• Color master batch or temperature resistance
• 2 to 8
• parts;
• master batch
• Polyamide-Diphenyl-methane-diisocyanate/
• 3 to 10
• parts;
• polytetramethylene ether glycol thermoplastic
• elastomer
• Functional master batch
• 2 to 10
• parts;
• Glass fiber toughening agent
• 5 to 10
• parts;
• Processing agent
• 1 to 3
• parts;
• wherein the functional master batch is obtained by mixing and granulating a material comprising the following raw materials by weight percentage;
• Polyolefin resin
• 50 wt % to
• 80 wt %;
• Light stabilizer
• 1 wt % to
• 10 wt %;
• Antioxidant
• 1 wt % to
• 10 wt %;
• Antistatic agent
• 1 wt % to
• 15 wt %;
• Plasticizer
• 0.5 wt % to
• 5 wt %;
• and the processing agent is one or more selected from silicone polymers and fluoropolymers;
• and
• wherein the method for preparing the straight fibers is:
• mixing Polyamide, the color master batch or the temperature resistance master batch, Polyamide-Diphenyl-methane-diisocyanate/polytetramethylene ether glycol thermoplastic elastomer, the glass fiber toughening agent and the processing agent, melting, extruding and thereafter cooling to obtain primary fibers;
• subjecting the primary fibers to softening, drawing, shrinkage, setting and winding to obtain the straight fibers;
• the draw ratio of the drawing is from 3 to 4.
