The present invention relates to a covering fabric for covering aircraft. The fabric itself is coated with one or more layers of a crosslinked anionic aliphatic polyester-polyurethane dispersion and/or is woven from coated fibres or filaments. A covering fabric of the invention is glued using a thermoactivatable heat-crosslinking adhesive. An advantage of the covering fabric of the invention is that there is no need for further coating of the fabric after covering, and thus significantly less weight is applied by the covering process. Furthermore, the user is able to apply the covering to an aircraft without using any organic solvents in adhesives, dope, thinners, fillers or paint, and so an environmentally friendly process is provided for the covering of aircraft.
L'invention concerne un tissu d'entoilage destiné à recouvrir un aéronef. Le tissu lui-même est recouvert d'une ou plusieurs couches d'une dispersion de polyester-polyuréthane aliphatique, anionique et réticulée et/ou il est tissé à partir de fibres ou de filaments recouverts. Le tissu d'entoilage de l'invention est collé au moyen d'un adhésif pouvant être réticulé à la chaleur et thermoactivé. De manière avantageuse, il n'est pas nécessaire de recouvrir de nouveau le tissu après la couverture, ainsi le poids appliqué par le processus d'entoilage est sensiblement réduit. De plus, l'utilisateur peut appliquer le tissu d'entoilage sur un aéronef sans utiliser des solvants organiques dans les adhésifs, les laques de tension, les agents de dilution, les diluants, ou les peintures, ce qui permet d'obtenir un procédé écologique pour l'entoilage d'aéronefs.
