Chemical Bonding
Fleissner offers a Chemical Bonding Process for new lines and upgrade for existing lines.
Besides the traditional binder bonding process Fleissner has developed a high speed process where the web is preentangled via the Fleissner AquaJet.

Other variations:
Double-sided impregnation with 1 mixer Double-sided impregnation with 2 mixersAdvantages of foam application compared to liquid application:
Less wet pick-up => less drying capacity Wide range of application down to minimum application Surface impregnation and through-impregnation More uniform binder distribution in the surface Less risk of migration during drying Improved volume of nonwoven Good textile hand Advantages of the Highspeed binder bonding process:
Speed of up to 200 m/min Higher tensile strength of the web Better distribution of the binder in the dewatered moist web Less binder pick-up necessary due to pre-entanglement of carded websProcess:
Light pre-entangling of carded webs with AquaJet technology De-wartering of the web by suction Chemical bonding with Highspeed foam padder Drying with can dryer and TAD dryer Applications:
Hygiene Technical textiles Wipes Medical applications
