A high-quality non-infill turf system is not just a carpet. It is a three-layer engineered structure. Each layer has a specific role, and all three must work together.
Layer 1: Yarn Layer — 7:3 Straight-and-Curled Bionic Support Matrix
The surface yarn layer is the first line of support. A single yarn type is usually not enough to balance support, cushioning, and recovery.
Vivaturf uses a 7:3 straight-and-curled bionic yarn matrix in suitable non-infill systems.
The approximate functional logic is:
- 70% high-modulus straight yarns create the main support framework
- 30% high-resilience curled yarns provide cushioning, elastic recovery, and fiber interaction
The straight yarns may reach a tensile modulus of around 1,200 MPa, helping the fibers maintain upright stability without relying on infill. The curled yarns may achieve a recovery rate of around 95%, supporting comfort and resilience while helping the straight yarns recover after loading.
This structure allows the turf surface to resist collapse while still maintaining a more comfortable and natural foot feel.
In some advanced product designs, DNA-like spiral or 3D-shaped yarn structures may also be used to improve fiber interlocking, upright stability, and long-term recovery.
