Traditional chemical-repellent coatings for workwear are mainly based on long perfluoroalkyl chain molecules (PFCs), deposited through conventional 'wet' coating or padding processes. However, these PFCs are under restriction by REACH, and the wet processes consume a huge amount of water, energy and chemicals. This is why wet chemical-based textile processing are gradually being substituted by dry-finishing processes such as plasma. Until now, plasma technologies have not yet proven to be really suitable for textile applications. The plasma technology PlasmaMax by AGC Plasma can achieve high deposition rates with high uniformity and allows functional coating without damaging the web. In this paper, an oil-repellent coating and a fluorine-free water-repellent finish on PE fabrics are presented. Finally, one example of protective layer against corrosion, in case of low-emissivity application, is shown for information.
