Method for the production of yarn for fields of articicial grass by extruding polymer granulate to bands or to a film, cutting the film into bands and stretching the bands, in which the bands having a width of 1.5-4 mm are stretched at a stretching ratio of 1 to 2-3 to bands having a width of 0.75-3 mm whilst the thickness is 50-80% of the thickness of the extruded bandand then 5-10 bands are twisted into the yarn
