Abstract
A substrate for floorings, such as synthetic grass turf includes: a pad made of a first heat-meltable material, a stabilizing mesh made of a second heat-meltable material, and a connection layer set between said pad and the mesh. The connection layer includes a third heat-meltable material with a melting point lower than the melting point of the first and of the second heat-meltable materials. The connection layer is a discontinuous layer with a granular structure, so that the substrate is permeable to liquids in order to enable, for example, draining-off of rainwater.
Claims27
A substrate for floorings, comprising:
- a pad including at least one unmelted first heat-meltable material;
- a stabilizing mesh comprising at least one unmelted second heat-meltable material;
- and
- a connection layer between said pad and said mesh, said connection layer comprising a third heat-meltable material with a melting point lower than a melting point of said first meltable material and said second heat-meltable material, said connection layer connected to said mesh and said pad by melting of said third heat-meltable material to cause a mechanical connection of said mesh to said pad;
- and
- said connection layer being a discontinuous layer formed of a plurality of granules separated from each other with openings therebetween so that said substrate is permeable to liquids through said openings;
- wherein said mesh includes yarns extending lengthwise of said substrate and yarns extending crosswise of said substrate, wherein said lengthwise yarns are of said second heat-meltable material and said crosswise yarns are of a further heat-meltable material and are melted to bond said crosswise yarns to said further heat-meltable material.
A method for producing a substrate for floorings, comprising:
- placing a stabilizing mesh comprising at least one second heat-meltable material on a pad including at least one first heat-meltable material;
- sowing a plurality of granules of a third heat-meltable material on said mesh to form a connection layer, the plurality of granules separated from each other with openings therebetween so that said substrate is permeable to liquids through said openings;
- applying heat to at least said connection layer at a temperature intermediate between the melting points of said first and said second heat-meltable materials and the melting point of said third heat-meltable material to melt said third heat-meltable material to cause a mechanical connection of said mesh to said pad.
