The standard thermal bonding 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 batt former opens and aligns the fiber in a 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.
- Drafting: the web is drafted in order to become more uniform, to orient the fibers more in the machine direction and to reduce the weight as the drafter stretches the fiber.
- Bonding: the product coming from the web forming is thermobonded in the oven by the action of hot air crossing the product from the top and from the bottom.
- Finishing: according to the final application, the web can have different finishing like smoothing, calibrating and laminating by smoothers and calenders.
Finally the 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.
