Plasma polymerization with PlasmaPlus® is an extremely effective process to apply functional nano-layers on the surface of yarns. These layers can be adjusted to be hydrophilic or hydrophobic, depending on the precursors used. One relevant application in functionalization of textiles is fire-retardant coating.
The French institute CREPIM (Centre de Recherche et d’Etude sur les Procédés d’Ignifugation des Matériaux) has done extensive studies investigating the flame-retardant effect on textiles achieved by plasma polymerization. Even the application of very thin glass-like layers dramatically reduces the flammability of polymer fibers, due to the inorganic nature of the coating.
