         6 . Artificial turf according to  claim 1 , wherein said artificial turf comprises said first synthetic grass fibers having a height from 20 mm to 40 mm and said second synthetic grass fibers having a height from 10 mm to 34 mm, wherein the average height difference between the first and second synthetic grass fibers is at least 6 mm. 
     
     
         7 . Artificial turf according to  claim 1 , wherein said synthetic grass fibers are upright oriented cut-pile fibers. 
     
     
         8 . Artificial turf according to  claim 1 , wherein the respective synthetic grass fibers are arranged in bundles of synthetic grass fibers. 
     
     
         9 . Artificial turf according to  claim 1 , wherein the first and second synthetic grass fibers are arranged in different rows. 
     
     
         10 . Artificial turf according to  claim 9 , wherein rows of said first and second synthetic grass fibers are arranged in a random pattern, with the provision that a row of said first synthetic fibers is present after not more than 3 rows of said second synthetic grass fibers. 
     
     
         11 . Artificial turf according to  claim 9 , wherein the first synthetic grass fibers are randomly tufted across the artificial turf. 
     
     
         12 . Artificial turf according to  claim 1 , wherein the first and second synthetic fibers have a different cross-section, colour, colour hue, dtex, resiliency or any combination thereof. 
     
     
         13 . Artificial turf according to  claim 8 , wherein the synthetic fibers within a given bundle of fibers, have a different cross-section, colour, colour hue, dtex, resiliency or any combination thereof. 
     
     
         14 . Artificial turf according to  claim 1 , further comprising thatch yarns, said thatch yarns. 
     
     
         15 . Artificial turf according to  claim 1 , in the form of tiles.
