To judge whether non-infill turf will stay upright over time, buyers should look beyond pile height and density. The following technical indicators are more meaningful.
3.1 Yarn Modulus and Recovery Rate
These two parameters directly influence fiber self-supporting ability.
Recommended reference values for quality non-infill systems include:
- Yarn tensile modulus: preferably ≥1,000 MPa
- Fiber recovery rate: preferably ≥90%
Vivaturf’s high-modulus straight yarn can reach around 1,200 MPa, while its recovery performance can reach approximately 95% in suitable product systems.
This helps the turf recover after repeated compression and reduce the risk of permanent fiber collapse.
3.2 Upright Retention After Repeated Loading
Upright retention is one of the most direct indicators of anti-flattening performance. It measures how many fibers remain upright after simulated repeated foot traffic.
Vivaturf test data shows that after 10,000 cycles of simulated high-frequency loading, selected non-infill systems can maintain an upright retention rate of around 92%, compared with some ordinary non-infill products that may remain closer to 60%.
This indicates that a properly engineered non-infill system can maintain a more stable surface appearance and performance over time.
3.3 Wear Resistance and UV Aging Resistance
Wear and aging can reduce yarn modulus over time. Once yarn strength declines, flattening becomes more likely.
Vivaturf non-infill turf can be designed to achieve:
- Abrasion resistance: around 6,500 cycles under ASTM D3884 reference testing
- UV aging resistance: around 6,000 hours, compared with basic requirements that may be around 3,000 hours in some specifications
These values help support long-term outdoor use and reduce the risk of yarn brittleness, fading, and performance loss.
3.4 Shockpad and Compression Performance
Field flattening does not always come from the yarn. Sometimes it comes from the shockpad.
If a low-quality shockpad compresses permanently, the field may feel harder, uneven, or sunken over time. This affects both comfort and sports performance.
Vivaturf’s customized cushioning layer is designed to maintain a practical balance between support and comfort:
- Vertical deformation: approximately 5–8 mm
- Shock absorption: approximately 40%–55%
- Low compression set compared with ordinary foam layers
This helps the field maintain stable cushioning and avoid progressive collapse under long-term use.
3.5 Yarn Pull-Out Force
Anti-flattening also requires stable root anchoring.
Vivaturf’s reinforced backing system can help achieve yarn pull-out force values of around 35 N, reducing the risk of fiber loosening, tilting, or detachment under repeated loading.
4. Standardized Installation: Making Anti-Flattening Performance Work on Site
Good product parameters must be supported by proper installation. Even a well-designed non-infill turf system can underperform if the base, seams, or edge details are poorly handled.
Vivaturf follows a full-process quality control approach that aligns with relevant sports turf standards such as GB/T 20394-2019 Sports Artificial Turf and other applicable field performance requirements.
