For American football applications, Vivaturf applies targeted upgrades to these system components to support higher wear thresholds and more stable long-term field performance.
3.1 Fiber system
Vivaturf uses a HDPE + PA + nano wear-resistant additive formulation designed to increase mechanical durability. In the performance references you provided:
- Fiber linear density: 11,000–13,000 dtex
- Fiber thickness: 0.38–0.42 mm
- Fiber density: 15,000–17,000 tufts/m²
- Single-fiber breaking strength: ≥45 N
- Elongation at break: ≥50%
- Fiber pull-out strength: ≥4.5 N/mm
Compared with typical premium-category references, these values are positioned to improve resistance to repeated stress and reduce fiber loss during high-contact use.
3.2 Fiber geometry
Vivaturf’s American football configuration uses a 4D spiral profiled cross-section with a nominal angle of 35°, intended to better align with the contact and cutting mechanics common in American football. The cross-sectional area is described as larger than conventional fibers, while surface texturing is designed to reduce frictional wear and improve structural resilience.
3.3 Tufting and structural stability
The system uses ultra-high-density tufting with controlled tension and a mixed straight/curled yarn arrangement to improve stability and wear consistency. Relevant performance references include:
- Tufting uniformity: ≥99.5%
- Tuft spacing: 20–21 mm
- Tufting tension: ≥18 N/tuft
This helps maintain consistent wear behavior across the field and reduce weak zones.
3.4 Backing system
Vivaturf’s reinforced backing structure is described as a three-layer composite consisting of:
- wear-resistant composite layer
- fiberglass mesh reinforcement
- elastic cushioning layer
Referenced backing performance includes:
- Backing thickness: ≥3.5 mm
- Tensile strength: ≥25 MPa
- Tear strength: ≥40 N
- Taber abrasion resistance: ≥7,000 cycles
- Base adhesion / fit consistency: ≥99.8%
- Seam tensile strength: ≥60 N/cm
Together, these values suggest a system designed to resist both repeated compression and impact-related structural fatigue.
