Definitions
- Embodiments of the present disclosure generally relate to artificial turf filaments, articles incorporating artificial turf filaments, and their manufacture.
- Synthetic or artificial turf fields are increasingly being used as an alternative to natural grass turf for use on sport athletic fields, landscaping, or golf applications.
- conventional artificial turf fields can have poor attachment of the synthetic grass blades to the base portion of an artificial turf field resulting in easy detachment of the grass blades.
- further improvements are desired of artificial turf fields to reduce the amount of heat absorbed, as well as, providing improved sports performance characteristics (e.g., faster ball roll).
- Water may be applied to the artificial turf field to achieve the desired turf performance characteristics, while also controlling heat; however, the water can easily run off the surface of the synthetic grass blades resulting in poor cooling of the yarns and/or failure to provide the desired sports performance characteristics.
- artificial turf fields have improved over the years to appear more like natural grass, synthetic grass blades still exhibit a smoother, glossy appearance when compared to natural grass, which is not aesthetically pleasing.

- the Barmag/Oerlikon monofilament extrusion line includes a 40 mm extruder, a spinneret with 48 holes, a water bath, one stretching oven (hot air), and three annealing ovens (air).
- the water bath was set at 35 °C.
- the air gap between the spinneret and the water bath was set at 40 mm for all trials.
- the temperature of the stretching oven was set at 97 °C.
- Annealing ratios were set at, respectively, 0.72, 0.92 and 1.02 and the temperature of the three annealing ovens at respectively 118°C, 118°C and 115°C.
- inventive filaments were then analyzed and compared to comparative filaments for adhesion peel strength, hydrophilicity, tensile properties, surface roughness, and differential scanning calorimetry.
- inventive filaments were also analyzed and compared to the comparative filaments after exposure to accelerated weathering conditions for 1300 hours in the Xenon chamber of a weathering machine Q-sun XE-2 Xenon Test Chamber (Q-lab). The exposure time of 1300 hours was set to mimic 1 year of sun exposure in a climate similar to Florida.
- a CRE tensile testing machine (Instron) was used to measure the peel force of inventive and comparative filaments from a polyurethane substrate.
- a polyurethane precursor composition was poured onto a 9" x 12" sheet.
- Inventive and comparative filaments were each applied to the poured polyurethane precursor composition, and then heated for 15 minutes at 120°C.
- the specimens were subsequently allowed to cure for at least three days.
- Each specimen was sized to have a length x width x height of about 6" (150 mm) x 0.5" (12.7 mm) x 1/64" (0.20 mm).
- one inch of the filament was manually separated from the polyurethane substrate.
- the starting gap between the grips was set to 1" (25.4 mm) and the filament was placed in the movable grip while the polyurethane substrate was placed in the stationary grip.
- the filaments were peeled from the polyurethane substrate at a rate of 12 in/min (300 mm/min) until either the filament broke or until only one inch of filament/polyurethane substrate was left at the second end of the specimen.
- a trace is generated consisting of a series of peaks representing the force to peel the filament from the polyurethane substrate.
- the initial peak force was ignored (which represents approximately 0.5 inches of specimen separation), and the average of all peaks between the initial peak force and the stopping point was determined.
- At least five specimens of the inventive filaments were measured and at least five specimens of the comparative filaments were measured. The average of the five measurements for the inventive and for the comparative filaments was calculated.
- FIG. 2A depicted is an inventive filament after peeling.
- the filament was not easily peeled from the polyurethane substrate, and is shown with much of the inventive filament still adhered to the polyurethane substrate due to the filament breaking while it was peeled.
- FIG. 2B the comparative filament was easily peeled from the polyurethane substrate, and the comparative filament is shown completely separated from the polyurethane substrate.
- the hydrophilic properties of the inventive and comparative filaments were analyzed with respect to their respective water contact angles with tap water at room temperature, using standard contact angle measuring equipment, to compare the polarity of the filaments.
- the water droplet on the comparative filament shown in FIG. 3B has a more circular shape, and therefore, a higher water contact angle, than the water droplet on the inventive filament shown in FIG. 3A.
- the measured water contact angle value is lower for the inventive filament as compared to the comparative filament, indicating that the inventive filament surface has improved hydrophilicity (i.e., a more hydrophilic and polar surface), as compared to the comparative filament.
- the hydrophilic properties of the inventive and comparative filaments were also analyzed with respect to their respective water contact angles using tap water at room temperature after weathering (as described above) of the filaments, using contact angle measuring equipment. As shown in FIG. 5, the measured water contact angle value is lower for the inventive filament as compared to the comparative filament, even after weathering, indicating that the inventive filament surface has improved hydrophilicity (i.e., a more hydrophilic and polar surface), as compared to the comparative filament.
- Inventive and comparative filaments were measured for elongation % (i.e., the distance in percent that the filament sample will stretch from its original size to the point at which it breaks) and fiber force at break (i.e., the force required to break the filament sample in a linear direction) at break using an Instron tensile testing machine. The tests were performed at room temperature. Eight inventive filament samples having a fiber titer of 2050 dTex and a length of 100 mm were pulled at a test speed of 100 mm/min until break, at which point the elongation percent and force is recorded. Eight comparative filament samples having a fiber titer of 2030 dTex and a length of 100 mm were pulled at a test speed of 100 mm/min until break, at which point the elongation percent and force is recorded.
- the fiber elongation at break % was calculated to be the average of the eight elongation percent measurements for the inventive filaments and the average of the eight elongation percent measurements for the comparative filaments.
- the fiber force at break was calculated to be the average of the eight peak force measurements for the inventive filaments divided by its fiber titer, and the average of the eight peak force measurements for the comparative filaments divided by its fiber titer.
- FIG. 6A shows the surface of the comparative filament at ⁇ , ⁇ magnification (left photo) and at a 5,000X magnification (right photo).
- FIG. 6B shows the surface of the inventive filament at ⁇ , ⁇ magnification (left photo) and at 5,000X magnification (right photo).
- a visual comparison of the images shows that the surface of the inventive filament is rougher than the surface of the comparative filament.
- DSC was performed on the inventive and comparative filaments.
- the samples of each of the inventive and comparative filaments were heated tol50°C, cooled at 10°C/min, and the heat flow was recorded, as shown in FIG. 7A, by scanning from -40°C to 150°C at 10°C/min using DSC822e Differential Scanning Calorimeter (Mettler Toledo)
- the DSC cooling curve, as shown in FIG. 7B was also recorded by scanning from 180°C to -40°C at 10°C/min. Referring to FIGS. 7A & 7B, the curves show that no structural modification occurred to the inventive filament due to the fluorination process.
