A process for producing synthetic-grass structures and corresponding synthetic-grass structure

Abstract From the Canadian patent

A synthetic-grass flooring, for example for sports activities, is made starting from a substrate (1) with a plurality of filiform formations (2) extending upwards from the substrate (1) to simulate naturalgrass cover or turf, the filiform formations (2) being provided with respective proximal ends (2a) and distal ends (2b) with respect to the substrate (1). The aforesaid distal ends (2b) are subjected to curling to bestow upon said filiform formations (2) a general tree-like conformation. The synthetic-grass flooring in question can be made in the form of the finished product of an industrial manufacturing process comprising a particulate filling material or infill (3) withheld on said …
