Needlepunch

Needlepunch is a mechanical bonding technique, where the fibers from a spunbond or carded web are interlocked using barbed felting needles. These needles repeatedly pass in and out of the web, allowing the interlocking and intermingling of different fiber types to introduce desired properties to the material.

The fibers used in this process are fed to the needle loom, where thousands of barbed needles travel back and forth through the holes on the needling plates. This blends the fibers, creating a stronger web structure. However, the needle punching process can mark the surface structure.

The mixture of different fiber types may affect surface uniformity of the finished material. Automated monitoring can inspect the material without affecting production speeds, support product quality and alert the operator to any defects that may cause a process break.
