DTEX is commonly used to describe the linear density of synthetic fibers.

In broadly comparable fiber systems, a higher linear density can provide greater material mass and potentially improve durability.

However:

Higher DTEX does not automatically mean better artificial turf.

Excessive fiber weight can affect:

• Foot feel
• Ball interaction
• Fiber recovery
• System weight
• Manufacturing cost
• Overall field characteristics

A properly engineered non-infill turf system therefore seeks an appropriate balance between:

DTEX + fiber thickness + cross-sectional geometry + density + resilience.

Fiber Cross-Sectional Design Can Improve Long-Term Performance

The geometry of an artificial turf fiber can influence bending stiffness, resilience, load distribution, and recovery.

Common engineered profiles include:

• S-shaped fibers
• C-shaped fibers
• U-shaped fibers
• Diamond-shaped fibers
• Hollow profiles
• Other three-dimensional engineered profiles

Compared with simple flat fibers, engineered cross-sections can provide additional structural support and improve the way fibers respond to repeated loading.

This is particularly relevant to non-infill turf because the system is designed to maintain its performance without relying on large quantities of particulate infill.

A well-designed fiber therefore needs to provide a balance between:

strength + flexibility + resilience + recovery.
