Latex/spray bonding (LBAL)
Liquid binder, such as latex is sprayed on both sides of the web to bind the fibers together. The excess moisture is then dried and the latex is cured in the drying section.
Thermal bonding (TBAL)
The web is formed using synthetic and organic (fluff pulp) fibers. Thermal energy is applied to the web which makes the synthetic fibers to bind with each other.
Hydrogen bonding (HBAL)
The web is bonded using one of the following methods:
- Moisture (H2O) & high pressure calendering.
- Water needling (spunlacing)
Multi bonding (MBAL)
LBAL + TBAL
Airlaid paper can be combined with other materials, such as plastic foil to produce surgical sheets for example.
