Toward Industrial Scale
Electrostatic impregnation process developed by Fibroline

At the pilot and then industrial scales, impregnation is part of a three-step process:

• an initial step involving feeding the substrate and metering the powder onto the textile substrate to apply the desired amount of powder;

• followed by the dry electrostatic impregnation step to drive the powder into the pores of the substrate;

• and finally, a curing step to ensure that the powder remains trapped within the porous substrate.
