Spiral felting needle

Features:

- Equilaterally formed triangular working part with a defined twist

- Barb dimensions are identical across the edge

- Modifies barb arrangement on the working part compared to the standard felting needle

Benefits:

- More efficient needling due to higher fiber transportation

- Improved tensile strength and better isotropic properties of the end product due to modified barb arrangement

- Optimized surface quality of the end product

- Higher production speeds possible due to reduced penetration density

- Good compaction of the non-woven fabric

- Compared to standard felting needles, the twisted working part does not cause any detrimental bending strength properties

- Higher degree of splitting when using microfibers

Fields of application:

- Automotive sector (visible)

- Filtration
