Abstract: A process for producing a fluorinated polymer coating on a fabric substrate, including providing a first plasma source containing at least one pair of hollow-cathode plasma generating electrodes, injecting a first plasma generating gas in the at least one pair of hollow-cathode plasma generating electrodes, applying a first electrical power to the first plasma source, injecting a fluorinated monomer with an inert carrier gas between the at least one pair of hollow-cathode plasma generating electrodes, and depositing the fluorinated polymer coating on a surface of the fabric substrate by exposing the fabric substrate to the plasma of the first plasma source. The fluorinated polymer coating is water repellent.
