Infrared Bonding and Curing Systems
topic
Infrared heating systems for nonwoven bonding use short-wave or medium-wave infrared emitters that transfer radiant heat directly to the web surface without convective air as required for through-air bonding, enabling faster heating response, precise temperature control, and reduced energy consumption at 20 to 40 percent of equivalent hot air oven systems for surface bonding of thermoplastic webs and binder pre-drying applications.
Role
Provides energy-efficient surface heating for nonwoven bonding and binder pre-drying through direct radiant heat transfer that reduces the energy consumption and heating zone length required compared to convective hot air systems, with infrared heating being particularly effective for surface bonding of thermoplastic spunbond and meltblown webs where surface heating is preferred over full-thickness heat penetration.
