A common misconception is that increasing tuft density automatically makes artificial turf more resistant to flattening.

This is not necessarily true.

If density is too low, individual fibers have less mutual support.

If density is excessively high, however, fibers may become crowded and have less room to flex and recover.

Excessive density can also influence:

• Drainage
• Surface feel
• Fiber recovery
• Ventilation
• Manufacturing cost

For this reason, density should be matched with:

• Grass height
• Fiber profile
• Dtex
• Straight/curly fiber ratio
• Backing strength
• Intended traffic level

The goal is balanced density rather than maximum density.

Pay Attention to Fiber Resilience

Fiber resilience describes the ability of synthetic grass fibers to recover after compression.

A useful evaluation method is to examine recovery after controlled compression rather than relying only on visual appearance.

For higher-performance products, buyers may request laboratory data covering:

• Compression recovery
• Fiber recovery
• Accelerated aging
• Tensile strength retention
• Tuft withdrawal strength

Testing methods and acceptance criteria vary between standards and applications, so buyers should compare test reports using the same methodology rather than comparing isolated numbers from different test systems.
