Method of making artificial turf and artificial turf made thereof

A method for making an artificial turf, the method comprising:

• providing a carrier and an artificial turf fiber incorporated into the carrier such that a first portion of the artificial turf fiber protrudes to a back side of the carrier, a second portion of the artificial turf fiber protrudes to a front side of the carrier, and a third portion of the artificial turf fiber is inside the carrier;
• preparing a polyurethane (PU) foam reaction mixture containing a reactive foam stabilizer (RFS), wherein the RFS is a substance adapted to stabilize the PU foam reaction mixture;
• and
• applying the PU foam reaction mixture on the back side of the carrier to cover the artificial turf fiber protruding to the back side of the carrier and allowing the PU foam reaction mixture to harden to form a flexible PU backing securing the turf fiber in place.

An artificial turf comprising:

• a carrier and an artificial turf fiber incorporated into the carrier such that a first portion of the artificial turf fiber protrudes to a back side of the carrier, a second portion of the artificial turf fiber protrudes to a front side of the carrier, and a third portion of the artificial turf fiber is inside the carrier;
• and
• a flexible polyurethane (PU) foam backing formed on the back side of the carrier securing the artificial turf fiber by covering the second portion of the artificial turf fiber,
• wherein the flexible polyurethane foam backing comprises covalent bonds of at least one of oleic acid, linoleic acid, stearic acid, palmitic acid, or ricinoleic acid, preferably, palmitic acid or ricinoleic acid, and more preferably ricinoleic acid with carbon atoms of an isocyanate used in the formation of the polyurethane backing.
