Manufacturing Artificial Grass

• polypropylene or polyethylene pigment granules, so called polymers, are heated until they form a paste to which a UV- and heat stabilizer (anti-shrinking) is added;

• the fluid mass is then extruded by a plate with small holes, monofilaments, or it is extruded to a very thin film that is cut in small strips and perforated so that a honeycomb structure is formed, fibrillated fibre;

• on a uv stabilized polypropylene woven fabric, bundles of artificial fibres are tufted in loops in the form of a line or a zigzag and then latexed to the back, the loops are cut and the tufted fabric is perforated;

• the density of the needles or gauge (e.g. 3/8”) together with the number of tufts per meter run (e.g. 200), determines the number of knots (which is in this case 21.000) and the weight (normally between 2 and 4 kg) per m2;

• during the drying process at 90ºC, the latex coating hardens and then the artificial fibre can either be curled or frizzled;

• there are variations in height (from a few millimeters to 6-7 cm) and in colour (several shades of green, also red or brown gravel imitations for tennis courts and even white, yellow and blue for lines);

• rolls can be up to 5 m wide and up to 70 m long.
