Liquid fall impregnation
The liquid fall impregnation is used when the nonwovens have to be supported by a conveyor belt during an impregnation by liquid binder. In order to have an optimal impregnation uniformity Sicam has developed a process based on a sort of liquid blade which falls down evenly on the material making the impregnation during the passage through the nonwoven .
The binder in excess is sucked away by proper slots under the conveyor and then recovered in a cyclone separator.
