Method of delaying and reducing texture reversion of a textured artificial turf yarn

A method of delaying and reducing texture reversion of a textured artificial turf yarn, the method comprising:

• providing a monofilament yarn comprising a polymer mixture, wherein the polymer mixture is at least a three-phase system, wherein the polymer mixture comprises a first polymer, a second polymer, and a compatibilizer, wherein the first polymer and the second polymer are immiscible, wherein the first polymer forms polymer beads surrounded by the compatibilizer within the second polymer;
• stretching the monofilament yarn to elongate the polymer beads to increase a volume of a crystalline fraction in the polymer mixture, and to form the monofilament yarn into a stretched monofilament yarn;
• and
• texturing the stretched monofilament yarn to form the textured and stretched monofilament yarn,
• wherein the elongating of the polymer beads and the increasing of the volume of a crystalline fraction delay and reduce the texture reversion of the textured and stretched monofilament yarn, and
• wherein the texturing of the stretched monofilament yarn includes performing a gas-dynamic texturing process such that a portion of the crystalline fraction of the polymer mixture is in a solid state and another portion of the crystalline fraction of the polymer mixture is in a molten state.
