Stitch density refers to the number of tufting stitches per unit area.
A higher stitch density can contribute to:
- More uniform visual coverage
- Greater fiber support
- Better load distribution
- Reduced visible gaps
However, excessive density can increase material usage and may restrict movement between fibers.
For many sports-oriented non-infill systems, a practical market range may be approximately 18,000–25,000 stitches/m², with higher-density configurations used for certain applications.
The important point is that Dtex and stitch density must be matched.
For example:
High Dtex + low density may leave excessive gaps.
Low Dtex + extremely high density may produce an overly soft or crowded surface.
A properly engineered system seeks an appropriate balance rather than maximizing individual numbers.
7. Pile Height Should Match the Application
Pile height is another frequently misunderstood specification.
Higher pile does not automatically mean a better or more comfortable turf surface.
For non-infill systems, excessive pile height can potentially increase the tendency toward:
- Fiber bending
- Surface instability
- Uneven ball interaction
- More difficult maintenance
Typical application ranges can be considered as follows:
Football
Approximately 35–50 mm, depending on the sport, system design, and applicable performance requirements.
School Multi-Purpose Areas
Approximately 25–35 mm can provide a practical balance between durability, comfort, and maintenance.
Recreational Courts
Approximately 20–30 mm may be appropriate for certain applications.
Landscaping and Residential Areas
Approximately 20–35 mm is commonly used, depending on the desired appearance and traffic level.
These ranges should be treated as design references rather than universal requirements.
For certified sports installations, the final pile height should be selected according to the relevant sport-specific performance criteria.
