Weight

The weight of a felt body is a key parameter that influences its structure and performance. 

It is typically defined as the starting weight (in grams) and directly affects how the material behaves during shaping and finishing.

Impact on Performance

Different weight ranges correspond to different product characteristics:

• Lower weights (80-120g)
  • Lighter and more flexible
  • Easier to shape
  • Suitable for softer constructions
• Medium weights (120-180g)
  • Balanced flexibility and structure
  • Versatile across multiple styles
• Higher weights (180-300g)
  • Greater density and rigidity
  • Enhanced durability and shape retention
  • Ideal for structured or western hats

Weight evolution during production

The final weight of the felt body may vary throughout the process due to:

• Finishing operations (e.g. pouncing, velour)
• Fiber loss during sanding
• Dyeing and treatment processes
• Stiffening grade, if applied

FEPSA defines target weight ranges and tolerances to ensure consistency across production batches.

Technical Control

Weight is controlled through:

• Defined starting weight specifications
• Process monitoring and inspection
• Target values with acceptable tolerances

This ensures reliable performance and repeatability for industrial applications.

Customization

FEPSA offers flexibility in weight selection according to:

• Desired stiffness and structure
• Type of finish
• Final application

Our technical team can support the definition of the most suitable weight range for each product.
