Abstract

The invention provides for a method of delaying and reducing texture reversion of a textured artificial turf yarn (145), characterized by using a stretched and textured monofilament yarn as the textured artificial turf yarn, the stretched and textured monofilament yarn comprising a polymer mixture (400, 500), wherein the polymer mixture is at least a three-phase system, wherein the polymer mixture comprises a first polymer (402), a second polymer (404), and a compatibilizer (406), wherein the first polymer and the second polymer are immiscible, wherein the first polymer forms polymer beads (408) surrounded by the compatibilizer within the second polymer.
