Three in one: intensive needling, gentle on fiber, and high quality
Tri STAR® needles are distinctive for their concave shaped working-part surfaces with narrower edge angles. This provides better fiber transport due to the enhanced grip of fibers in the barb. Fiber transportation is improved, leading to more intensive needling.
The cross sectional area of the equilateral shaped working part of the Tri STAR® is around 8% smaller than a standard triangular-shaped working part.
Tri STAR® needles are used for production of geo-nonwovens for highway construction, separation and filter felts, coating carriers, safety nonwovens and geo-membranes.
The benefits of the Tri STAR® in relation to a standard needle lie in the applications, the required product characteristics, and the machines on which it is used:
