The standard needling process using staple fiber includes the following steps:
- Fiber Opening and Blending: the bales of fiber are opened and blended and fed into the web forming section of the production line.
- Web Forming: the web former further opens and aligns the fibers in parallel direction with a card.
- Crosslapping: the web is layered to increase the fabric’s cross directional strength and improve fabric uniformity. The crosslapper allows to produce fabrics wider than the card and to increase the web basic weight by increasing the frequency of cross-laps.
- Needlepunching: the web is bound in the needle-loom by the action of needles binding the fibers.
- Finishing: according to the final application, the web can have different finishing like bonding by the use of adhesive resins or calendering with heat and pressure, embossing or laminating.
Finally the needlepunched product is ready to be shipped, generally in rolls winded by end of line units that also allow to slit and crosscut the product in the desired size. Before shipping the rolls are usually manually or automatically wrapped and strapped into pallets.
