Abstract
A synthetic turf having a mat with a face arranged adjacent to a surface to coat, and a face opposite the face. The turf includes a plurality of blades made of a synthetic material that are connected to the mat. Above the face of the mat, an infill material is provided that is arranged among the blades. The infill material includes a predetermined percentage by volume of a vegetable material consisting of rachis of cereal ear. The infill material also includes a predetermined percentage by volume of a ligninic and/or resinous material of vegetable origin.
Claims9
A synthetic or hybrid synthetic-natural turf for sports, recreational, or ornamental uses, comprising:
- a mat having a first face arranged on a surface to be covered and a second face opposite the first face;
- a plurality of blades of synthetic material connected to and extending from said second face, and forming a synthetic mat;
- and
- an infill material distributed on said second face;
- wherein the infill material consists of a first layer consisting of a mixture of:
- a predetermined percentage by volume of a vegetable material consisting of rachis of cereal ear that is not coated by a layer, or film, of material, and wherein said vegetable material consisting of rachis of cereal ear has a granulometry of between 0.3 mm and 5.0 mm;
- a predetermined percentage by volume of a vegetable ligninic and/or resinous material containing lignin and/or resin, being resistant to attack by microorganisms;
- and
- a predetermined percentage by volume of a loose final product from raw material based on ground cork;
- and
- a second layer positioned below the first layer and consisting of a vegetable material consisting of rachis of cereal ear that is not coated by a layer, or film, of material.
