System and method for producing artificial turf filaments
View Patent ↗A system and method for producing artificial turf filaments according to one example embodiment includes an artificial turf filament, a first air drawn oven for heating the filament, a roll stand for applying an aqueous liquid to the filament and a second air drawn oven for heating the filament. In multiple embodiments, the filament has a latent helix shape when exposed to manufacturing or ambient heat.
1. A system for manufacturing artificial turf filaments for artificial turf surfaces, the system comprising:
a spinneret that forms a plurality of artificial turf filaments by melt extrusion;
a first air drawn oven downstream of the spinneret that heats the plurality of artificial turf filaments to a first temperature;
a roll stand downstream of the first air drawn oven that applies an aqueous liquid to coat the plurality of artificial turf filaments;
a second air drawn oven downstream of the roll stand that heats the plurality of filaments to a second temperature, wherein the second temperature is higher than the first temperature.
2. The system of claim 1 ,
wherein each of the plurality of artificial turf filaments exhibits a latent helix shape during manufacturing or when exposed to ambient heat.
3. The system of claim 1 ,
wherein each of the extruded artificial turf filaments has fine surface distortions.
4. The system of claim 2 ,
wherein the latent helix shape is exhibited when the filaments are exposed to manufacturing heat of about 85 degree C.
5. The system of claim 2 ,
wherein the latent helix shape is exhibited when the filaments are exposed to ambient heat of about 65.56 degree C.
