Parmi les produits à base de silicones que l'on peut utiliser, les caoutchoucs de silicones offrent des avantages particuliers. On peut les appliquer aisément sur le5 tissu ou le corps plan textile par les divers procédés industriels et les réticuler en place en élastomères de silicones correspondants dans des conditions appropriées. En outre, ils forment pour le tissu apprêté une excellente protection mécanique et thermique, attendu qu'il est connu que les élastomères de silicones se caractérisent par une très grande stabilité à la chaleur.

L'inconvénient technique des revêtements formés avec de tels produits réside dans le fait qu'ils ont une The technical disadvantage of coatings formed with such products is that they have
faible adhérence à des substrats organiques. low adhesion to organic substrates.
On connaît dans la littérature technique une série de propositions qui ont été faites à ce propos pour supprimer cet inconvénient. Par exemple, on peut adjoindre aux caoutchouc d'organopolysiloxanes des composés organiques de silicium qui ont pour effet d'améliorer l'adhérence du revêtement de caoutchouc de silicone. Il est en outre connu que par le traitement par exemple d'une matière textile avec des solutions diluées des composés organiques de silicium mentionnés avant l'application de la matière de revêtement, on obtient parfois de nettes améliorations de l'adhérence du revêtement. Pour des matières textiles supportant une haute charge mécanique, comme on en utilise en particulier pour la fabrication de textiles industriels pour coussins gonflables de sécurité autrement appelés "airbags" dans la construction automobile, l'amélioration qui peut être atteinte concernant l'adhérence du revêtement ne suffit toutefois encore pas pour le but d'utilisation. L'objet de l'invention réside donc dans un procédé de production de corps plans textiles ou de textiles tissés, notamment pour la fabrication de tissus pour coussins gonflables de sécurité, doués d'adhérence supérieure à une couche d'élastomère de silicone qui y est appliquée, caractérisé en ce que le textile ou le corps plan textile est exposé à une décharge électrique silencieuse (décharge avec effet de couronne) avant l'enduction avec le caoutchouc de silicone. On a observé le fait surprenant que l'utilisation d'agents adhésifs dans une matière à base de caoutchouc d'organopolysiloxane conduisait uniquement en association avec un traitement de décharge avec effet de couronne à une liaison particulièrement durable entre la couche d' élastomère de silicone et le tissu de support utilisé pour la production A number of proposals have been made in the technical literature to overcome this drawback. For example, organopolysiloxane rubbers may be supplemented with organic silicon compounds which have the effect of improving the adhesion of the silicone rubber coating. It is further known that by treating, for example, a textile material with dilute solutions of the organosilicon compounds mentioned before application of the coating material, there are sometimes marked improvements in the adhesion of the coating. For textile materials with a high mechanical load, as used in particular for the manufacture of industrial textiles for airbags otherwise known as "airbags" in the automotive industry, the improvement that can be achieved concerning the adhesion of the coating however, is still not sufficient for the purpose of use. The object of the invention lies therefore in a method for producing flat planar bodies or woven fabrics, in particular for the manufacture of airbag fabrics with superior adhesion to a layer of silicone elastomer which is applied, characterized in that the textile or textile flat body is exposed to a silent electric discharge (corona discharge) prior to coating with the silicone rubber. Surprisingly, the use of adhesive agents in an organopolysiloxane rubber-based material only led in combination with a corona discharge treatment to a particularly durable connection between the silicone elastomer layer. and the supporting fabric used for production

Des dispositifs destinés à la production des décharges électriques conformes à l'invention pour la modification de surfaces de polymères sont connus sous la notion d'électrode à effet de couronne et leur utilisation a été largement répandue pour le traitement de surface de Devices for the production of electric discharges according to the invention for the modification of polymer surfaces are known under the concept of corona electrode and their use has been widely used for the surface treatment of

rer l'adhérence de couleurs, de peintures, de colles et de revêtements. On utilise avantageusement une décharge avec effet de couronne d'une fréquence de 1 à 500 kHz, notamment adhesion of colors, paints, glues and coatings. Advantageously, a corona discharge with a frequency of 1 to 500 kHz is used, in particular
de 5 à 30 kHz.from 5 to 30 kHz.
La tension peut se situer entre 3 et 30 kV, de The voltage can be between 3 and 30 kV,
préférence entre 20 et 31 kV.preferably between 20 and 31 kV.
Des doses d'irradiation de 10 à 1000 gAh/m2 sont généralement suffisantes, selon le tissu. Des doses plus Irradiation doses of 10 to 1000 gAh / m2 are generally sufficient, depending on the tissue. More doses
fortes n'entraînent pas d'autre amélioration de l'adhérence. strong do not result in further improvement of adhesion.
La décharge avec effet de couronne peut être conduite à la température ambiante dans une atmosphère formée d'air ou d'un gaz inerte, une certaine humidité de l'air, par exemple au-dessus de 50 %, étant relativement avantageuse. L'enduction avec le caoutchouc liquide de silicone devrait être effectuée de préférence dans une installation continue, immédiatement à la suite du traitement par effet de couronne. Si le traitement par effet de couronne et l'enduction sont effectués à des moments différents dans des installations séparées dans l'espace, il peut être nécessaire d'utiliser de plus fortes doses d'irradiation afin d'obtenir le plein effet conforme à l'invention, attendu que les centres actifs favorisant l'adhérence, créés sur le tissu The corona discharge may be conducted at ambient temperature in an atmosphere of air or an inert gas, with some humidity of the air, for example above 50%, being relatively advantageous. Coating with liquid silicone rubber should preferably be performed in a continuous installation immediately following the corona treatment. If corona treatment and coating are carried out at different times in separate installations in space, it may be necessary to use higher doses of irradiation in order to obtain the full effect in accordance with the invention, since the active centers promoting adhesion, created on the fabric
