Abstract

On peut enduire des objets textiles par dépôt en phase gazeuse par procédé physique ou chimique. Les couches déposées sur les fibres ou filaments sont de haute qualité. On peut ainsi enrober les filaments ou les fibres, sans laisser des pores, avec des couches très minces, lesquelles entraînent toutefois une augmentation imperceptible du volume total de l'objet textile. Compte tenu de la haute mobilité des particules du matériau d'enrobage, même des points critiques tels que les points d'enchaînement dans des tissus maillés ou tissés, sont enduits de manière fiable. Cela vaut également pour des corps textiles façonnés tridimensionnels, de formes complexes. Après l'enduction par simple dépôt, on peut également effectuer des polymérisations de la surface, de manière à créer des couches impénétrables sur le matériau textile qui, soit le protège contre l'environnement (allergie, sensibilité à l'air, sensibilité à la lumière) soit lui confèrent des propriétés nouvelles (conductivité électrique, revêtement anti-adhésif). L'enrobage par dépôt en phase gazeuse empêche également, dans de nombreux cas, l'objet textile à traiter de se dessécher.
