The Science Behind Needle Punching
Needle punching is a mechanical process that creates non-woven fabrics by interlocking fibres using barbed needles. Understanding this process helps explain the unique properties of needle punch felts.
The process begins with a web of loose fibres, which may be carded, air-laid, or otherwise prepared. This web passes through a needle loom containing thousands of barbed needles that repeatedly penetrate the material.
As the needles pass through, the barbs catch fibres and pull them vertically through the horizontal web. This creates mechanical bonds between fibres without adhesives or thermal bonding.
The result is a dense, stable fabric with good dimensional stability and consistent properties. By adjusting needle density, penetration depth, and number of passes, we can control the characteristics of the finished felt.
