Title (EN) ARTIFICIAL TURF WITH MARBLED MONOFILAMENT
(FR) GAZON SYNTHÉTIQUE À MONOFILAMENT MARBRÉ
Abstract:
(EN) The invention provides for a method of manufacturing artificial turf (1000), the method comprising the steps of: - creating (100) a liquid polymer mixture (100, 400, 500), wherein the polymer mixture is at least a two-phase system, a first one (402) of the phases comprising a first polymer and a first dye, a second one (404) of the phases of the polymer mixture comprising a second polymer and a second dye, the second dye having a different color than the first dye, the second polymer being of the same or of a different type as the first polymer, the first and the second phase being immiscible, the first phase forming polymer beads within the second phase; - extruding (102) the polymer mixture into a monofilament (606) comprising a marbled pattern of the first and second color; - quenching (104) the monofilament; - reheating (106) the monofilament; - stretching (108) the reheated monofilament to deform the polymer beads into threadlike regions (800) and to form the monofilament into an artificial turf fiber (1004); - incorporating (110) the artificial turf fiber into an artificial turf backing (1002).
(FR) L'invention concerne un procédé de fabrication de gazon synthétique (1000), le procédé comprenant les étapes suivantes : la création (100) d’un mélange polymère liquide (100, 400, 500), le mélange polymère étant au moins un système à deux phases, une première phase (402) comprenant un premier polymère et un premier colorant, une seconde phase (404) du mélange polymère comprenant un second polymère et un second colorant, le second colorant ayant une couleur différente de celle du premier colorant, le second polymère étant du même type ou d'un type différent du premier polymère, les première et seconde phases étant non miscibles, la première phase formant des billes de polymère dans la seconde phase ; l’extrusion (102) du mélange polymère en un monofilament (606) comprenant un motif marbré des première et seconde couleurs ; la trempe (104) du monofilament ; le réchauffage (106) du monofilament ; l’étirage (108) du monofilament réchauffé pour déformer les billes de polymère en régions filiformes (800) et pour transformer le monofilament en une fibre de gazon synthétique (1004) ; l’intégration (110) de la fibre de gazon synthétique dans un support de gazon synthétique (1002).
