Structuring needles – structuring technology
Structuring needles are tasked with structuring previously bonded nonwoven fabric in special machines.
These surfaces are produced with a velvety or grainy character, and may also feature geometric or linear patterns.
Fork and crown needles are structuring needles that are differentiated by their geometry.
Fork and crown needles
While crown needles generate a particularly uniform structure, fork needles are used to create a grainy structure.
Fork needle
Fork needles have a single- or multi-reduced intermediate section with a cylindrical working-part. The significant functional element is the fork opening on the working part.
Crown needle
The design of the crown needle is identical to that of felting needles; the only difference is in the arrangement of the barbs. There is exactly one barb on the edge of each working part.
