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.
