Creation of needle punched nonwovens is mechanical: the fibers of a web from carding or Spunbond process are oriented and entangled with a lot of barbed felting needles. The Needled Nonwoven Fabric Process and Production of needled nonwoven fabric are based on layering of fibers into a loose matting structure; then the fibers are entangled thanks to needles which penetrate through their mass (web).
In the Needled Nonwoven Fabric Process and Production the initial mechanical entanglement (needling or waterjet) has the function to interlace the filaments of the layers into one single layer, while the other needling steps are intended to create the fabric with all the specifications required (density and other characteristics). We always pay attention to quality and efficiency, and our designs are done in order to ensure to our customers the best results they can expect.
The typical Needled Nonwoven Fabric Process and Production are carried out as per the following in-line steps (with all or part of them):
- Staple fibers opening (bale opener)
- Staple fibers Fine opening
- Pre-needling and Needling/Waterjet
- Surface calendering
- Thermosetting and calibration
- Drying and binder polymerization
- Surface finishing and calibration
- Slitting and winding
