Mixed turf

Abstract

Provided is a mixed turf, positioned on a terrain. The mixed turf includes a synthetic turf lawn with natural turf placed within the synthetic turf lawn. The synthetic turf lawn also includes synthetic filaments configured to simulate blades of turf and a media including a non-biodegradable membrane sustaining the synthetic filaments. The media is positioned inside said terrain and is substantially draining, breathable and permeable to the roots of said natural turf. The media includes a textile made of a plurality of twines superposed and reciprocally woven together, each one having a base, which is periodically repeated along substantially the entire textile. Each twine has a base of different dimensions compared to the other twines along the extension plane of the textile.

1 . A mixed turf, positioned on a terrain and comprising:
 a synthetic turf lawn; and   natural turf placed within said synthetic turf lawn,
 said synthetic turf lawn comprising synthetic filaments to simulate blades of turf and a media comprising a non-biodegradable membrane sustaining said synthetic filaments, 
 said media being positioned inside said terrain and being in its entirety substantially draining, breathable and permeable to the roots of said natural turf, 
 said media including a textile that comprises a plurality of twines superposed and reciprocally woven together, each one having a base, which is a portion of minimal dimension which is periodically repeated along substantially the entire fabric, which repeats periodically substantially along the entire textile, and 
 each of said twines has a base of different dimensions compared to the other said twines along the extension plane of said textile. 
   
     
     
         2 . The mixed turf according to  claim 1 , wherein said textile comprises three superposed twines. 
     
     
         3 . The mixed turf according to  claim 1 , wherein said textile comprises apertures having mean dimensions of the main orthogonal diameters, of from 2 mm to 0.5 mm. 
     
     
         4 . The mixed turf according to  claim 1 , wherein said textile comprises apertures having different mean dimensions of the main orthogonal diameters and the lesser diameter has a length of from 0.6 mm to 0.4 mm so as to prevent the passage of the sand and permit the passage of the roots. 
     
     
         5 . The mixed turf according to  claim 1 , wherein said textile comprises polyester threads. 
     
     
         6 . The mixed turf according to  claim 1 , wherein said textile is starched. 
     
     
         7 . The mixed turf according to  claim 1 , wherein said textile is a warp-knitted type textile. 
     
     
         8 . The mixed turf according to  claim 1 , wherein said media comprises a non-woven textile connected to the lower part of said textile and configured to connect said synthetic filaments to said media. 
     
     
         9 . The mixed turf according to  claim 8 , wherein said non-woven textile has a density of from 1 g/cm 3  to 3 g/cm 3 . 
     
     
         10 . The mixed turf according to  claim 1 , wherein said media comprises a coat of glue configured not to close the apertures of said textile and, on the lower part of said textile configured to connect said synthetic filaments to said media.
