Saturation and Impregnation Bonding Systems
topic
Saturation bonding immerses the fibre web in a latex or resin binder solution through a nip padder or kiss roller applying binder at 20 to 50 percent add-on followed by squeezing to defined wet pick-up and oven curing at 120 to 180 degrees Celsius, with binder penetration through the full web thickness providing uniform bond distribution that creates strong nonwovens for wipes, filter media, and industrial fabrics requiring high wet strength.
Role
Produces strongly bonded nonwovens through full-thickness binder penetration that bonds fibres throughout the web cross-section, providing superior wet strength retention and structural integrity compared to surface spray or foam bonding that deposits binder preferentially at the web surface, with saturation bonding being preferred for nonwovens requiring maximum wet strength for aggressive cleaning, filtration, and industrial applications.
