Tufted artificial turf comprising a flexible, water-permeable support fabric provided with tufts, wherein the tufts comprise parts of straight monofilament yarn and parts of curly monofilament yarn, wherein said tufts are manufactured from a compound yarn composed by twining together said straight monofilament yarn with the curly monofilament yarn. 
   
   
       2 . Artificial turf according to  claim 1 , wherein said straight monofilament yarn and said curly monofilament yarn are manufactured from polyamide 6, polyamide 6.6 or polyamide 6.12, and preferably from polyamide 6. 
   
   
       3 . Artificial turf according to  claim 1 , wherein a resting height of the curly yarn is between ⅕ to ⅗, preferably ⅓ to ⅔ of the length of the straight monofilament yarn in the tufts and still more preferably amounts to approximately ½ thereof. 
   
   
       4 . Artificial turf according to  claim 1 , wherein said straight and curly monofilament yarn each comprises 4 to 12 individual filaments, preferably 6 to 10 individual filaments, and more preferably 8 individual filaments. 
   
   
       5 . Artificial turf according to  claim 1 , wherein said individual filaments of the straight monofilament yarn each have a yarn number of between 500 and 2000 dtex, preferably of between 750 and 1500 dtex, and most preferably of 1000 dtex. 
   
   
       6 . Artificial turf according to  claim 1 , wherein said individual filaments of the curly monofilament yarn each have a yarn number of between 300 and 1500 dtex, preferably of between 500 and 1000 dtex, and most preferably of 750 dtex. 
   
   
       7 . Artificial turf according to  claim 1 , wherein said individual filaments have a width of between 0.5 and 2 millimetre, preferably of between 0.75 and 1.5 millimetre, and most preferably of 0.9 millimetre. 
   
   
       8 . Artificial turf according to  claim 1 , wherein said individual filaments have a thickness of between 50 μm and 200 μm, preferably of between 100 μm and 150 μm, and most preferably of 140 μm. 
   
   
       9 . Artificial turf according to  claim 1 , wherein said composed yarn has a yarn number of between 10,000 and 20,000 dtex, preferably of between 12,000 and 16,000 dtex, more preferably of between 13,000 and 15,000 dtex, and most preferably of 14,000 dtex. 
   
   
       10 . Artificial turf according to  claim 1 , wherein said tufts are arranged in rows which are located on mutual distances of between 4/16″ and 6/16″. 
   
   
       11 . Artificial turf according to  claim 1 , wherein said tufts have an average height of between 30 to 50 mm, preferably of between 35 to 40 mm and most preferably of 38 mm.
