La présente invention a trait, d'une part, à un dispositif de support ' sur lequel sont fixées des molécules présentant une activité, soit à l' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré, d'autre part, à un procédé consistant à assurer la présence et la fixation de telles molécules actives au niveau d'un tel support et, d'autre part encore, à une composition destinée à mettre en œuvre ce procédé et/ou à être associée audit support.The present invention relates, on the one hand, to a support device ' to which molecules exhibiting activity are fixed, either against organisms or undesirable phenomena, or in favor of a desired phenomenon, d on the other hand, to a process consisting in ensuring the presence and the fixation of such active molecules at the level of such a support and, on the other hand, to a composition intended to implement this process and / or to be associated audit support.
L'invention concerne le domaine du traitement des supports et trouvera son application lorsqu'il s'agit de réaliser des supports qui présentent des propriétés particulières conférées par des molécules actives, notamment dans le cadre de la protection de ce support ou d'un élément recevant un tel support, à l' encontre d'effets indésirables.The invention relates to the field of the treatment of supports and will find its application when it is a question of producing supports which have particular properties conferred by active molecules, in particular within the framework of the protection of this support or of an element. receiving such support, against adverse effects.
L'on connaît, d'ores et déjà, un certain nombre de dispositifs de support présentant de telles propriétés et faisant appel, pour assurer la présence de molécules actives à leur niveau, à différents types de procédés .We already know a certain number of support devices having such properties and calling, to ensure the presence of active molecules at their level, different types of processes.
Un premier procédé consiste à assurer la fixation de molécules sur un support en réalisant une liaison covalente entre ce support et ces molécules. Tel est, par exemple, le cas, lorsqu'il s'agit de fixer des molécules colorantes sur un support, notamment cellulosique. Un tel procédé présente un certain nombre d'inconvénients consistant en ce que la réalisation d'une liaison covalente, d'une part, nécessite l'intervention de produits chimiques spécifiques ainsi qu'un apport substantiel d'énergie et, d'autre part et surtout, provoque une modification chimique irrémédiable du support ainsi que de la structure et de l'activité des molécules ce qui n'est pas admissible.A first method consists in ensuring the attachment of molecules to a support by making a covalent bond between this support and these molecules. This is, for example, the case when it comes to fixing coloring molecules on a support, in particular cellulosic. Such a method has a certain number of drawbacks consisting in the fact that the production of a covalent bond, on the one hand, requires the intervention of specific chemicals as well as a substantial supply of energy and, on the other hand and above all, causes an irremediable chemical modification of the support as well as of the structure and the activity of the molecules which is not admissible.
Un autre procédé consiste à assurer la fixation de molécules sur un support en réalisant un collage de ces molécules à l'aide d'un liant. Un tel collage est, en fait, réalisé par polymérisation de ce liant à haute température ce qui présente un certain nombre d'inconvénients consistant, d'une part, en une rigidification du support et, d'autre part, en un noyage des molécules au sein du liant ce qui rend ces molécules totalement inactives. La présente invention se veut à même de remédier aux inconvénients des dispositifs et des procédés de l'état de la technique .Another method consists in ensuring the attachment of molecules to a support by bonding these molecules using a binder. Such bonding is, in fact, achieved by polymerization of this binder at high temperature, which has a certain number of drawbacks consisting, on the one hand, of a stiffening of the support and, on the other hand, of a flooding of the molecules within the binder which makes these molecules completely inactive . The present invention seeks to overcome the drawbacks of the devices and methods of the prior art.

L'invention est exposée plus en détail dans la description qui va suivre se rapportant à un mode de réalisation donné à titre d'exemple et illustré dans les figures des dessins joints en annexe dans lesquels :The advantages of the present invention consist in that the active molecules are fixed on said support through an ionic bond which, on the one hand, ensures a solid and durable fixing of such an active molecule on this support and, d on the other hand, in no way distorts the active properties of such a molecule. According to another advantage of the invention, the fact of providing said support with means arranged to achieve an ionic bond and / or of providing the active molecules with complementary means arranged to achieve an ionic bond, makes it possible to envisage fixing a multitude of types of active molecules on a multitude of types of supports, which makes it possible, in particular, to respond effectively to the problem of fixing a particular active molecule on a particular support, this according to a particular need. The invention is explained in more detail in the description which follows, relating to an embodiment given by way of example and illustrated in the figures of the appended drawings in which:
- les figures 1 et 2 correspondent à une vue schématique de deux types de supports et de deux types de molécules actives avant fixation de ces dernières sur un tel support ; la figure 3 est une vue schématique de la fixation de molécules actives sur un support conformément à la présente invention ; L'invention concerne le domaine du traitement des supports et trouvera son application lorsqu'il s'agit de réaliser des dispositifs de support qui présentent des propriétés particulières conférées par des molécules actives.- Figures 1 and 2 correspond to a schematic view of two types of supports and two types of active molecules before fixing the latter on such a support; Figure 3 is a schematic view of the attachment of active molecules to a support in accordance with the present invention; The invention relates to the field of support treatment and will find its application when it is a question of producing support devices which have particular properties conferred by active molecules.
En fait, cette invention concerne, d'une part, un procédé consistant à assurer la présence et la fixation, au niveau d'un support 1, l', de molécules 2, 2' présentant une activité, notamment chimique, bio-chimique, physique ou analogue, soit à l' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré et, d'autre part, un dispositif 10 de support sur lequel sont fixées de telles molécules 2, 2' présentant une telle activité.In fact, this invention relates, on the one hand, to a method consisting in ensuring the presence and the fixing, at the level of a support 1, l ′, of molecules 2, 2 ′ exhibiting activity, in particular chemical, bio-chemical activity , physical or analogous, either against organisms or undesirable phenomena, or in favor of a desired phenomenon and, on the other hand, a support device 10 on which are fixed such molecules 2, 2 'having such activity.
Cette invention est, plus particulièrement, illustrée dans les figures en annexe représentant un support 1 ; l' au niveau duquel est assurée la présence (figues 1 et 2) et la fixation (figure 3) de molécules actives 2 ; 2' présentant une activité, notamment chimique, bio-chimique, physique ou analogue. En ce qui concerne le procédé selon l'invention, celui-ci consiste en ce que l'on assure la présence, au niveau du support 1 ; 1' présentant des moyens 3 ; 3' agencés pour réaliser une liaison ionique, de molécules actives 2 ; 2' dont au moins une partie présente des moyens 4 ; 4' complémentaires agencés pour réaliser une liaison ionique.This invention is, more particularly, illustrated in the appended figures representing a support 1; the at which is ensured the presence (figs 1 and 2) and the fixation (figure 3) of active molecules 2; 2 'having an activity, in particular chemical, bio-chemical, physical or similar. As regards the method according to the invention, this consists in ensuring the presence, at the level of the support 1; 1 having means 3; 3 'arranged to produce an ionic bond, of active molecules 2; 2 'at least part of which has means 4; 4 'complementary arranged to achieve an ionic bond.
Ce procédé consiste, encore, en ce que l'on assure une fixation de ces molécules 2 ; 2' sur ledit support 1 ; l' , ceci au travers de la coopération entre les moyens 3 ; 3' de liaison ionique dudit support 1 ; l' et les moyens 4 ; 4' complémentaires de liaison ionique desdites molécules actives 2 ; 2'.This process also consists in ensuring that these molecules 2 are fixed; 2 'on said support 1; the, this through cooperation between the means 3; 3 'of ionic bonding of said support 1; the and means 4; 4 'complementary ionic bonding of said active molecules 2; 2 '.
Tel que visible sur les figures en annexe, les moyens 3, 3' agencés pour réaliser une liaison ionique sont définis par au moins une charge électrique présente au niveau du support 1, l' tandis que les moyens 4, 4' complémentaires agencés pour réaliser une liaison ionique sont définis par au moins une charge électrique, de signe opposée à celle des moyens 3, 3' présents au niveau dudit support 1, 1', et présente au niveau d'une molécule active 2, 2'.As visible in the appended figures, the means 3, 3 'arranged to produce an ionic connection are defined by at least one electric charge present at the level of the support 1, l' while the complementary means 4, 4 'arranged to produce an ionic bond are defined by at least one electric charge, of opposite sign to that of the means 3, 3 'present at the level of said support 1, 1', and present at the level of an active molecule 2, 2 '.
Ainsi et tel qu'il ressort des figures en annexe, la charge électrique du support 1 peut être cationique tandis que la charge électrique d'une molécule active 2 est anionique (figure 1) ou inversement (figure 2) .Thus and as it appears from the appended figures, the electrical charge of the support 1 can be cationic while the electrical charge of an active molecule 2 is anionic (Figure 1) or vice versa (Figure 2).
A ce propos, on observera que, selon un premier mode de réalisation, l'invention peut consister en ce que l'on utilise un support 1 de type cationique à l'origine et au niveau duquel on assure la présence de molécules 2 de type anionique ou anionisê (figure 1) . Un autre mode de réalisation consiste en ce que l'on utilise un support l' de type anionique à l'origine et au niveau duquel on assure la présence de molécules 2' de type cationique ou cationisé (figure 2) .In this regard, it will be observed that, according to a first embodiment, the invention may consist in using a support 1 of cationic type at the origin and at the level of which the presence of molecules 2 of type is ensured. anionic or anionized (Figure 1). Another embodiment consists in using a support l ′ of anionic type at the origin and at the level of which the presence of 2 ′ molecules of cationic or cationized type is ensured (FIG. 2).
Cependant et selon un autre mode de réalisation non représenté, il peut être envisagé de recourir à un support 1 ; l' de type neutre à l'origine et que l'on va pourvoir de moyens 3 ; 3' agencés pour réaliser une liaison ionique, plus particulièrement constitués par au moins une charge électrique, selon le cas, cationique 3 ou anionique 3 ' . Pour ce faire, le procédé selon l'invention consiste en ce que, avant d'assurer la présence de molécules actives 2 ; 2' au niveau du support 1 ; l', on procède à un traitement de ce support 1 ; l' de manière à le pourvoir de moyens 3 ; 3' agencés pour réaliser une liaison ionique.However and according to another embodiment not shown, it can be envisaged to use a support 1; the originally neutral type and which will be provided with means 3; 3 'arranged to produce an ionic bond, more particularly constituted by at least one electric charge, as the case may be, cationic 3 or anionic 3'. To do this, the method according to the invention consists in that, before ensuring the presence of active molecules 2; 2 'at the support 1; the, we proceed to a treatment of this support 1; the so as to provide it with means 3; 3 'arranged to achieve an ionic bond.
Un tel traitement consiste à imprégner ledit support 1 ; l' à l'aide d'une composition contenant au moins une solution polymérisable et/ou rêticulable contenant des moyens 3 ; 3' agencés pour réaliser une liaison ionique. A ce propos, on remarquera qu'il est possible de procéder à une telle imprégnation, soit en immergeant ledit support 1, l' dans un bain d'imprégnation (par exemple liquide) contenu dans une cuve contenant une telle composition, soit en pulvérisant (à l'aide d'un dispositif de pulvérisation comme, par exemple, au moins une buse ou analogue) une telle composition sur ledit support, soit en enduisant (à l'aide d'un dispositif d'enduction comme, par exemple un rouleau, un pinceau ou analogue) ledit support à l'aide d'une telle composition.One such treatment consists in impregnating said support 1; using a composition containing at least one polymerizable and / or crosslinkable solution containing means 3; 3 'arranged to achieve an ionic bond. In this regard, it will be noted that it is possible to carry out such an impregnation, either by immersing said support 1, the in an impregnation bath (for example liquid) contained in a tank containing such a composition, or by spraying (using a spraying device such as, for example, at least one nozzle or the like) such a composition on said support, either by coating (using a coating device such as, for example a roller, brush or the like) said support using such a composition.
En ce qui concerne ladite solution polymérisable et/ou rêticulable, celle-ci est constituée par un mélange d'au moins un premier produit polymérisable et/ou rêticulable non ionique avec au moins un second produit présentant les moyens 3, 3' pour réaliser une liaison ionique, à savoir une matière de type cationique ou anionique . A ce propos et selon un premier mode de réalisation consistant à obtenir un support cationique 1, le procédé selon l'invention revient à assurer le traitement d'un support neutre à l'aide d'une solution polymérisable et/ou rêticulable de type cationique, qui peut, dans un pareil cas, être constituée par un mélange d'au moins un premier produit polymérisable et/ou rêticulable non ionique, avec au moins un second produit cationique présentant les moyens 3 agencés pour réaliser une liaison ionique.As regards said polymerizable and / or crosslinkable solution, it consists of a mixture of at least one first non-ionic polymerizable and / or crosslinkable product with at least one second product having the means 3, 3 ′ to produce a ionic bond, namely a material of cationic or anionic type. In this regard and according to a first embodiment consisting in obtaining a cationic support 1, the method according to the invention amounts to ensuring the treatment of a neutral support using a polymerizable and / or crosslinkable solution of cationic type. , which can, in such a case, consist of a mixture of at least one first polymerizable and / or cross-linkable non-ionic product, with at least one second cationic product having the means 3 arranged to produce an ionic bond.
Ainsi, le procédé peut consister en l'utilisation, à titre d'exemple de premier produit polymérisable non ionique, d'un liant à base de styrène butadiêne, de styrolène butadiène, d'acrylique, d'uréthane, de polyuréthane et/ou d'acétate de vinyle, voire encore d'un mélange à base de l'un au moins de ces composés.Thus, the process can consist in the use, by way of example of the first nonionic polymerizable product, of a binder based on styrene butadiene, styrene butadiene, acrylic, urethane, polyurethane and / or vinyl acetate, or even a mixture based on at least one of these compounds.
A titre d'exemple non limitatif de premier produit rêticulable non ionique, il est possible de faire appel à des résines de type DMDHEU (DiMéthylolDiHydroxyEthylêneUrée) , DMU (DiMéthylolUrêe) et/ouBy way of nonlimiting example of the first nonionic crosslinkable product, it is possible to use resins of the DMDHEU (DiMethylolDiHydroxyEthylêneUrée), DMU (DiMethylolUrêe) and / or
MF (Mélamine Formol) , voire encore à un mélange à base de l'une au moins de ces résines.MF (Melamine Formol), or even a mixture based on at least one of these resins.
Une telle solution polymérisable et/ou rêticulable contient, également, un second produit de type cationique qui, à titre d'exemple, peut être constitué par au moins un composé d'ammonium quaternaire, au moins un acide polysilicique modifié, au moins un produit dérivé de complexe de chrome ou analogue.Such a polymerizable and / or crosslinkable solution also contains a second product of cationic type which, by way of example, may consist of at least one quaternary ammonium compound, at least one modified polysilicic acid, at least one product derived from chromium complex or the like.
En fait, un mode particulier de réalisation consiste à faire appel à un mélange contenant, d'une part, de 50g à 80g/l d'une solution aqueuse d'un polymère acrylique non ionique et, d'autre part, de 50 à 100g/l d'une solution aqueuse d'une polyamine quaternisëe cationique, voire encore tout autre composé fortement cationique. Finalement, d'autres possibilités consistent à employer une solution polymérisable et/ou rêticulable de type cationique, une telle solution ayant été préalablement préparée de manière à être prête à l'emploi et pouvant être constituée à base d'aminé quaternaire.In fact, a particular embodiment consists in using a mixture containing, on the one hand, from 50 g to 80 g / l of an aqueous solution of a nonionic acrylic polymer and, on the other hand, from 50 to 100 g / l of an aqueous solution of a cationic quaternized polyamine, or even any other highly cationic compound. Finally, other possibilities consist in employing a polymerizable and / or crosslinkable solution of cationic type, such a solution having been previously prepared so as to be ready for use and can be constituted on the basis of quaternary amine.
Un autre mode de réalisation du procédé selon l'invention consiste à réaliser un support anionique à partir d'un support neutre, plus particulièrement en imprégnant ce dernier à l'aide d'une solution polymérisable et/ou rêticulable de type anionique. Un mode de réalisation particulier consiste en ce qu'une telle solution résulte du mélange, d'une part, de 50 à 80 g/1 d'une solution aqueuse d'un polymère acrylique anionique et, d'autre part, de 20 à 40 g/1 d'une solution aqueuse de carboxy-méthylcellulose, voire encore de tout autre composé fortement anionique. Finalement, on remarquera qu'il est, là encore, possible de recourir à une solution polymérisable et/ou rêticulable de type anionique ayant été préparé préalablement de manière à être prête à l'emploi. II convient d'observer que les constituants d'une telle solution polymérisable et/ou rêticulable (cationique ou anionique) présentent une concentration qui sera déterminée en fonction du taux d'absorption ou d'adsorption du support 1, l'.Another embodiment of the method according to the invention consists in producing an anionic support from a neutral support, more particularly by impregnating the latter with the aid of a polymerizable and / or crosslinkable solution of anionic type. A particular embodiment consists in that such a solution results from the mixture, on the one hand, of 50 to 80 g / l of an aqueous solution of an anionic acrylic polymer and, on the other hand, of 20 to 40 g / 1 of an aqueous solution of carboxy-methylcellulose, or even of any other strongly anionic compound. Finally, it will be noted that it is again possible to use a polymerizable and / or crosslinkable solution of anionic type having been prepared beforehand so as to be ready for use. It should be observed that the constituents of such a polymerizable and / or crosslinkable solution (cationic or anionic) have a concentration which will be determined according to the rate of absorption or adsorption of the support 1, l '.
Selon une autre caractéristique de la présente invention, la composition, destinée à imprégner le support 1, l' , peut encore contenir au moins un catalyseur conçu apte à assurer une fixation d'une solution polymérisable et/ou rêticulable sur ce support 1, l' .According to another characteristic of the present invention, the composition, intended to impregnate the support 1, l ', may also contain at least one catalyst designed capable of ensuring a fixing of a polymerizable and / or crosslinkable solution on this support 1, l '.
Encore une autre caractéristique du procédé selon l'invention consiste en ce qu'une telle composition d'imprégnation peut, encore, contenir, soit un tensioactif élaboré à base de dérivés éthoxylénës, soit un tensioactif non ionique (notamment constitué par un composé alcoolique, par exemple, l'alcool isopropylique) . Un tel tensioactif est conçu apte à traiter un support 1, l' présentant un caractère hydrophobe .Yet another characteristic of the process according to the invention consists in that such an impregnating composition may, again, contain either a surfactant made from ethoxylenic derivatives, or a nonionic surfactant (in particular consisting of an alcoholic compound, for example, isopropyl alcohol). Such a surfactant is designed capable of treating a support 1, presenting it with a hydrophobic character.
Tel qu'il a été évoqué ci-dessus, l'imprégnation du support 1, 1' à l'aide de ladite composition peut être réalisée soit par immersion dans un bain, soit par pulvérisation, soit par enduction. A ce propos, on observera qu'une telle imprégnation est réalisée au moins une fois, ceci à l'aide d'une même solution polymérisable et/ou rêticulable ou à l'aide de solutions différentes. De plus, la nature, la vitesse et/ou la durée d'une telle imprégnation sont, de préférence, adaptées au type de support 1, l' , au type de solution polymérisable et/ou rêticulable utilisé et/ou au type de traitement souhaité.As mentioned above, the impregnation of the support 1, 1 ′ using said composition can be carried out either by immersion in a bath, or by spraying, or by coating. In this regard, it will be observed that such an impregnation is carried out at least once, this using the same polymerizable and / or crosslinkable solution or using different solutions. In addition, the nature, the speed and / or the duration of such an impregnation are preferably adapted to the type of support 1, the, to the type of polymerizable and / or crosslinkable solution used and / or to the type of treatment. wish.
Une caractéristique additionnelle de la présente invention consiste en ce que ce traitement, constitué par une imprégnation, est réalisé à une température inférieure à 50 °C, de préférence à température ambiante. Ce traitement peut, de plus, être complété par un essorage et/ou un traitement thermique (notamment après un essorage) et/ou un séchage (notamment réalisé à température ambiante dans le cas de matières polymérisables et/ou rêticulable) . A titre d'exemple, une telle imprégnation peut être complétée par un essorage suivi d'un séchage à une température d'environ 200°C pendant moins de 15 secondes ou à une température comprise entre 190 et 199 °C pendant 15 à 30 secondes ...

This treatment can, moreover, be supplemented by a spin and / or a heat treatment (in particular after a spin) and / or a drying (in particular carried out at ambient temperature in the case of polymerizable and / or crosslinkable materials). For example, such an impregnation can be completed by a spin followed by drying at a temperature of around 200 ° C for less than 15 seconds or at a temperature between 190 and 199 ° C for 15 to 30 seconds ... As mentioned above, the method according to the invention consists in ensuring the presence, at the level of a support 1; the, of molecules active 2; 2 'at least part of which has means 4; 4 'complementary arranged to achieve an ionic bond.
A ce propos, il convient d'observer que, selon un premier mode de réalisation, il est possible de recourir à des molécules 2 d'origine anionique dont il s'agit d'assurer la présence au niveau d'un support cationique 1 comme visible figure 1.In this regard, it should be observed that, according to a first embodiment, it is possible to have recourse to molecules 2 of anionic origin, the presence of which is to be ensured at the level of a cationic support 1 as visible in figure 1.
Selon un autre mode de réalisation, il est possible de recourir à des molécules 2' d'origine cationique dont il convient d'assurer la présence au niveau d'un support anionique l' (figure 2) . Cependant et selon un autre mode de réalisation, le procédé selon l'invention consiste à assurer la présence, au niveau d'un support cationique 1 ou anionique l', de molécules d'origine neutres. A ce propos, on observera que, avant d'assurer la présence de telles molécules au niveau d'un tel support 1, l', l'invention consiste à procéder à un traitement d'une partie au moins de ces molécules de manière à les pourvoir de moyens 4, 4' complémentaires agencés pour réaliser une liaison ionique.According to another embodiment, it is possible to use molecules 2 ′ of cationic origin, the presence of which must be ensured at the level of an anionic support 1c (FIG. 2). However and according to another embodiment, the method according to the invention consists in ensuring the presence, at the level of a cationic or anionic support 1 ', of molecules of neutral origin. In this regard, it will be observed that, before ensuring the presence of such molecules at the level of such a support 1, the, the invention consists in carrying out a treatment of at least part of these molecules so as to provide them with complementary means 4, 4 ′ arranged to produce an ionic bond.
Un tel traitement revient, selon le cas, à anioniser ou à cationiser les molécules actives neutres et consiste à réaliser, soit une dispersion contenant des molécules actives non ioniques sous forme dispersée en présence d'un dispersant ionique (selon le cas, anionique ou cationique) , soit une émulsion contenant des molécules actives non ioniques sous forme émulsionnée en présence d'un émulgateur ionique (selon le cas, anionique ou cationique) . En fait et selon une autre caractéristique de l'invention, lorsque l'on assure la présence de molécules actives 2 ; 2', au niveau d'un support 1 ; l', l'on procède à une imprégnation de ce dernier 1 ; l', à l'aide d'une composition composée au moins en partie de molécules actives 2 ; 2' pourvues de moyens 4, 4' complémentaires agencés pour réaliser une liaison ionique.Such a treatment amounts, as the case may be, to anionizing or cationizing the neutral active molecules and consists in producing either a dispersion containing nonionic active molecules in dispersed form in the presence of an ionic dispersant (depending on the case, anionic or cationic ), or an emulsion containing non-ionic active molecules in emulsified form in the presence of an ionic emulsifier (as the case may be, anionic or cationic). In fact and according to another characteristic of the invention, when ensuring the presence of active molecules 2; 2 ', at a support 1; the, one impregnates the latter 1; l ', using a composition composed at least in part of active molecules 2; 2 'provided with complementary means 4, 4' arranged to produce an ionic bond.
Une première technique d'imprégnation consiste, alors, à faire passer le support 1, l' dans au moins un bain contenant au moins une telle composition. Cependant et selon un autre mode de réalisation, une telle imprégnation peut être réalisée au travers de la pulvérisation d'une telle composition sur le support 1, l' par exemple au moyen d'une ou plusieurs buses, d'un système rotatif de centrifugation ou de tout autre moyen équivalent. Finalement, un autre mode de réalisation consiste à assurer une enduction d'un tel support 1 ; l', à l'aide d'une composition composée au moins en partie de molécules actives 2 ; 2' pourvues de moyens 4 ; 4' complémentaires agencés pour réaliser une liaison ionique.A first impregnation technique then consists in passing the support 1, the in at least one bath containing at least one such composition. However and according to another embodiment, such an impregnation can be carried out by spraying such a composition onto the support 1, for example by means of one or more nozzles, of a rotary system of centrifugation or any other equivalent means.

A ce propos, l'on observera que, lorsque ces molécules 2, 2' se présentent sous une forme émulsionnable (respectivement dispersible) , la composition peut contenir un émulgateur (respectivement un dispersant, notamment constitué par des produits de condensation d'acides sulfoniques, carboxy-méthylcellulose) agencé pour permettre le maintien d'une émulsion (respectivement d'une dispersion) stable sans séparation de phase, sans décantation ou agrégat . Après qu'il ait été assuré la présence de ces molécules 2 ; 2' au niveau dudit support 1 ; l', la fixation de ces molécules 2 ; 2' est assurée automatiquement et instantanément au travers de la coopération entre, d'une part, des moyens 3 ; 3' agencés pour réaliser une liaison ionique et, d'autre part, des moyens 4 ; 4' complémentaires agencés pour réaliser une liaison ionique, une telle coopération permettant d'assurer un maintien solide et durable de ces molécules actives 2 ; 2' sur le support 1 ; l' .It will be observed, however, that whatever the impregnation technique used, the impregnation composition may be in the form of an emulsion or a dispersion or a solution, especially an aqueous solution, while the molecules active 2; 2 ′ can be in an emulsifiable or dispersible soluble form or in the form of microcapsules, preferably porous or other. In this regard, it will be observed that, when these molecules 2, 2 ′ are in an emulsifiable form (respectively dispersible), the composition may contain an emulsifier (respectively a dispersant, in particular consisting of condensation products of sulfonic acids , carboxy-methylcellulose) arranged to allow the maintenance of a stable emulsion (respectively of a dispersion) without phase separation, without decantation or aggregate. After it has been assured the presence of these molecules 2; 2 'at said support 1; the, the binding of these molecules 2; 2 'is ensured automatically and instantaneously through the cooperation between, on the one hand, means 3; 3 'arranged to achieve an ionic connection and, on the other hand, means 4; 4 'complementary arranged to achieve an ionic bond, such cooperation to ensure a solid and durable maintenance of these active molecules 2; 2 'on the support 1; the.

Ainsi et selon une autre caractéristique de la présente invention ledit support 1, l' peut être constitué, au moins en partie, par un matériau textile ou géotextile ou biotextile. Un tel matériau peut être de type naturel et/ou artificiel et/ou synthétique. Un tel matériau peut, encore, être, d'une part, tissé, non tissé ou tricoté et, d'autre part, brut, blanc, teinté ou imprimé ou encore se présenter sous la forme d'une fibre, d'un fil, d'un lé, d'un tube ou autre. En fait et selon un mode préféré de réalisation, un tel matériau textile ou gëotextile ou biotextile est, plus particulièrement, relatif à la confection ou à l'ameublement et se présente, par exemple, sous la forme d'un élément vestimentaire, d'une moustiquaire, d'un voilage ou analogue, voire encore sous la forme d'une pièce textile/géotextile/biotextile intervenant dans la réalisation de l'un au moins de ceux-ci.Thus and according to another characteristic of the present invention, said support 1, l 'can be constituted, at least in part, by a textile or geotextile or biotextile material. Such a material can be of natural and / or artificial and / or synthetic type. Such a material may also be, on the one hand, woven, non-woven or knitted and, on the other hand, raw, white, dyed or printed or else be in the form of a fiber, a thread. , a strip, a tube or other. In fact and according to a preferred embodiment, such a textile or geotextile or biotextile material is, more particularly, relating to the making or furnishing and is, for example, in the form of a clothing element, of a mosquito net, a curtain or the like, or even in the form of a textile / geotextile / biotextile part involved in the production of at least one of these.
Selon une autre caractéristique de la présente invention, les molécules actives 2, 2' peuvent, encore, être fixées sur une multitude d'autres supports de nature et de propriété différentes notamment un support 1, l', constitué, au moins en partie, en un matériau de type cellulosique (bois, papier, carton...) , métallique, béton, plastique ou autre.According to another characteristic of the present invention, the active molecules 2, 2 ′ can also be fixed on a multitude of other supports of different nature and property, in particular a support 1, l ′, consisting, at least in part, in a cellulose type material (wood, paper, cardboard ...), metallic, concrete, plastic or other.
Aussi, à titre d'exemple non limitatif, un tel support 1, l' peut être constitué par un élément constitutif ou décoratif d'un bâtiment, notamment un mur, un plafond, un dispositif de fermeture, un toit, un balcon, une terrasse sachant que ce support 1, l' peut encore être constitué par un revêtement ou un habillage associé à un tel élément constitutif ou décoratif comme, par exemple, une dalle, une tuile, un plafond tendu ou autre.Also, by way of nonlimiting example, such a support 1, the can be constituted by a constitutive or decorative element of a building, in particular a wall, a ceiling, a closing device, a roof, a balcony, a terrace knowing that this support 1, the can also be constituted by a covering or a covering associated with such a constitutive or decorative element such as, for example, a slab, a tile, a stretched ceiling or the like.
Tel qu'évoqué ci-dessus, le procédé et le dispositif 10 de support selon la présente invention présentent la caractéristique d'une fixation, sur un support 1, l', de molécules actives 2, 2' présentant une activité, notamment chimique, biochimique, physique ou analogue.As mentioned above, the method and the support device 10 according to the present invention have the characteristic of a fixation, on a support 1, l ′, of active molecules 2, 2 ′ exhibiting an activity, in particular chemical, biochemical, physical or the like.

De tels organismes vivants peuvent être constitués par des végétaux, notamment des mousses qui peuvent se développer au niveau d'un support 1, l' constitué par un élément constitutif/décoratif d'un bâtiment ou encore par un revêtement ou par un habillage de cet élément.Thus, such molecules 2, 2 'can exhibit activity against living organisms. Such living organisms can be constituted by plants, in particular mosses which can develop at the level of a support 1, the constituted by a constitutive / decorative element of a building or by a coating or by a covering of this element.

Dans ces derniers cas, les molécules actives 2, 2' peuvent être associées à un élément constitutif/décoratif d'un bâtiment, à un revêtement/habillage d'un tel élément, voire encore à un matériau de type textile/géotextile/biotextile, ceci en vue de conférer à ceux-ci des propriétés de répulsion ou de destruction de ces organismes vivants (notamment insecticide, insectifuge ou analogue) . A ce propos, on observera que la présente invention trouvera une application particulièrement intéressante lorsqu'il s'agit d'assurer le traitement de vêtements et/ou de moustiquaires à 1' encontre d'insectes, notamment de moustiques. En effet, au travers de la présente invention, il est possible de remédier à un certain nombre d'inconvénients rencontrés dans les traitements existants qui nécessitent un entretien périodique et une rêimprégnation du support après chaque lavage ou après tout traitement mécanique, voire encore à la suite d'intempéries (utilisation complexe du support traité, technique de rêimprégnation toxique, ceci pour un résultat et une efficacité limités dans le temps) . Ceci étant, le procédé selon l'invention permet l'obtention d'un dispositif 10 de support imprégné à l'aide de molécules actives 2, 2', cette imprégnation étant permanente et ne présentant aucun risque de contamination pour les hommes ou pour l'environnement.Such living organisms can also be formed by bacteria, microbes, mites, insects or the like.

That said, the method according to the invention makes it possible to obtain a support device 10 impregnated using active molecules 2, 2 ′, this impregnation being permanent and presenting no risk of contamination for men or for 'environment.
Un autre avantage de l'invention consiste en ce que lesdites molécules actives 2, 2' peuvent être sélectionnées en fonction de la zone géographique de destination dudit dispositif et/ou du type d'organisme vivant qu'il convient de traiter. Aussi, lorsqu'il s'agit de sélectionner des molécules actives 2, 2' présentant une activité à l' encontre de moustiques, il peut, avantageusement, être fait appel à de la per ethrine (substance agissant directement sur le centre nerveux des moustiques) à de la bifenthrine, à de l'éthophen prox ou encore à de l'alphacypermethrine qui sont des substances qui, d'une part, agissent directement sur le centre nerveux des moustiques et, d'autre part, sont particulièrement bien adaptés à une fixation sur un support 1, l' au travers d'une liaison ionique.Another advantage of the invention consists in that said active molecules 2, 2 ′ can be selected as a function of the geographic area of destination of said device and / or of the type of living organism which should be treated.
