SECTOR DE LA TECNICATECHNICAL SECTOR
La presente invencion se encuadra dentro del sector quimico-fisico, especificamente en el area de los biocidas y repelentes relacionados con enfermedades de transmision vectorial, especialmente al control de vectores y microorganismos patogenos en los campos de la salud publica, agricultura, y veterinaria. Tanto por su naturaleza y como por su aplicacion, la presente invencion se enmarca tambien en el sector textil, especialmente es tejidos de mantas, toallas, sabanas, cortinas, y cualquier prenda que se emplee en zonas susceptibles de enfermedades de transmision vectorial, como uniformes de campana militar.The present invention falls within the chemical-physical sector, specifically in the area of biocides and repellents related to vector-borne diseases, especially to the control of vectors and pathogenic microorganisms in the fields of public health, agriculture, and veterinary medicine. Both by its nature and by its application, the present invention is also framed in the textile sector, especially blanket fabrics, towels, sheets, curtains, and any garment used in areas susceptible to vector-borne diseases, such as uniforms of military bell.
ESTADO DE LA TECNICASTATE OF THE TECHNIQUE
Las enfermedades de transmision vectorial constituyen uno de los problemas mundiales mas importantes de Salud Publica y al mismo tiempo uno de los retos de la humanidad para los proximos anos tanto para los paises en desarrollo como para los del Norte, fruto de las migraciones y el cambio climatico. Los esfuerzos historicos de la ciencia y la medicina en los campos de los tratamientos de malaria, dengue, etc. se ven complementados recientemente con acciones preventivas, siendo la mas sobresaliente la utilizacion extensiva de mosquiteras. Analogamente las infecciones por microorganismos patogenos presentes en el ambiente poseen una incidencia tambien notable que puede abordarse tambien desde la vertiente preventiva.Vector-borne diseases are one of the most important global problems of Public Health and at the same time one of the challenges of humanity for the coming years for both developing and northern countries, the result of migration and change climate. The historical efforts of science and medicine in the fields of treatment of malaria, dengue, etc. they are recently complemented with preventive actions, the most outstanding being the extensive use of mosquito nets. Similarly, infections by pathogenic microorganisms present in the environment also have a notable incidence that can also be addressed from the preventive side.
La presente invencion pretende continuar en la linea de actuaciones de control de estas enfermedades, evitando los contagios mediante la doble repelencia que ejercen tanto los agentes microencapsulados como los micro y/o nanocristales que proporcionan una pelicula o lamina ahuyentadora de insectos y la accion biocida de nuevas sustancias, todo ello incorporado a productos a los que se desea conferir dichas propiedades, como son las prendas textiles. Para ello, la presente invencion se fundamenta en previos trabajos de los mismos inventores en el campo de la microencapsulacion de ingredientes activos de diversa naturaleza en matrices polimericas, como es la patente espanola - P9602723 relativa a pinturas inhibidoras de la sintesis de quitina de los artropodos para el control de plagas y alergenos; la patente mexicana MX309428 que divulga pinturas insecticidas y acaricidasThe present invention aims to continue in the line of actions to control these diseases, avoiding contagion through the double repellency exercised by both microencapsulated agents and micro and / or nanocrystals that provide a film or insect repellant film and the biocidal action of new substances, all incorporated into products to which these properties are to be conferred, such as textile garments. For this, the present invention is based on previous works by the same inventors in the field of microencapsulation of active ingredients of various kinds in polymeric matrices, such as the Spanish patent - P9602723 related to inhibitory paints of the chitin synthesis of arthropods for the control of pests and allergens; Mexican patent MX309428 that discloses insecticidal and acaricidal paints

La composicion de la microcapsula se encuentra descrita en la patente W02Q11045448 A1 de la Dra. Pilar Mateo, la cual asegura y prolonga en el tiempo la duracion de las sustancias con repelencia quimica, como las sustancias naturales, que normalmente sufren degradation rapida por agentes como la luz, la humedad y la oxidation. Esta innovation en e! campo de los insecticidas y repelentes ha demostrado ser eficaz en e! control de enfermedades como el Mai de Chagas en America del Sur y la Malaria en Africa.chitin synthesis inhibitors, juvenile insect hormone regulators and arthropod repellents, for the control of endemic diseases, pests and allergens; the Spanish patent ES2350075 B1 referring to a microencapsulated composition based on O / ea saponified Europaea, its use and its method of obtaining; and the Spanish patent application P201330802, related to a biocidal product flush and the method of incorporation of the biocidal product. The composition of the microcapsule is described in the patent W02Q11045448 A1 of Dr. Pilar Mateo, which ensures and prolongs in time the duration of substances with chemical repellency, such as natural substances, which normally undergo rapid degradation by agents such as Light, moisture and oxidation. This innovation in e! Field of insecticides and repellents has proven effective in e! control of diseases such as Mai de Chagas in South America and Malaria in Africa.
El objetivo social principal de la invencion es reducir la tasa de infection de estas enfermedades que tienen unas consecuencias terribles a nivel individual, familiar y por extension para los paises y organismos que actuan en las zonas de riesgo. En definitiva el saivar vidas de personas protegidas por las prendas textiles y consecuentemente limitar su propagation por nuevas picaduras e infecciones.The main social objective of the invention is to reduce the infection rate of these diseases that have terrible consequences at the individual, family level and by extension for the countries and organizations that operate in the risk areas. In short, the lives of people protected by textile garments and consequently limit their spread by new bites and infections.
En el apartado cientifico, la invencion aborda el uso de ingredientes activos naturales con accion insecticida, bactericida o virucida, entre otras, conjuntamente con ia incorporacion de cristales minerales y/u organicos de tamaho micro- y/o nanometrico que forman una lamina o pelicula sobre el textil con el objetivo de superar la generation de resistencias por parte de los insectos, que al cabo de los anos resultan ineficaces. Los genes de resistencia, que se encuentran de forma espontanea en la naturaleza solo se seleccionan cuando aportan una ventaja competitiva. La posibilidad de que ocurra una mutation es mayor cuando se trata de materias activas que actuan en un punto concreto a nivel bioquimico, pero es mucho mas improbable en moleculas con un modo de accion complejo o multi-site. Por otra parte la aparicion de resistencias a un fenomeno de tipo fisico es inviable. La solution del problema de las resistencias en insectos puede suponer un salto cuantitativo en la lucha contra estas enfermedades.In the scientific section, the invention addresses the use of natural active ingredients with insecticidal, bactericidal or virucidal action, among others, together with the incorporation of mineral and / or organic crystals of micro- and / or nanometer size that form a film or film on the textile with the aim of overcoming the generation of resistance by insects, which after years is ineffective. Resistance genes, which are found spontaneously in nature, are only selected when they provide a competitive advantage. The possibility of a mutation occurring is greater when it comes to active materials that act at a specific point at the biochemical level, but it is much more unlikely in molecules with a complex or multi-site mode of action. On the other hand, the appearance of resistance to a physical phenomenon is unfeasible. The solution of the problem of resistance in insects can be a quantum leap in the fight against these diseases.
Por ultimo, la invencion tiene un enfoque medioambiental alineado con las politicas internacionales sobre sustancias biocidas, que tienden a preservar la salud y el medioFinally, the invention has an environmental approach aligned with international policies on biocidal substances, which tend to preserve health and the environment.

Los cristales micro y/o nanometricos son particulas de crista! mineral y/u organico con tamano menor que la longitud de onda de De Broglie del subsistema de excitaciones electronicas. Esto quiere decir que se pueden tener efectos de confinamiento cuantico. Forman parte de un estado de materia intermedio entre los agregados moleculares y los materiales cristalinos. Sirven para hacer un seguimiento de la evolution de las propiedades de la materia de un extremo a otro. Los micro y/o nanocristales tienen una serie de propiedades parecidas a las de los cromoforos organicos:Micro and / or nanometric crystals are crystalline particles! mineral and / or organic with a size smaller than the De Broglie wavelength of the electronic excitation subsystem. This means that quantum confinement effects can be had. They are part of a state of intermediate matter between molecular aggregates and crystalline materials. They serve to track the evolution of the properties of matter from one extreme to another. The micro and / or nanocrystals have a series of properties similar to those of organic chromophores:
- alta section eficaz de absorcion,- high effective absorption section,
- rendimiento cuantico alto (aproximadamente de un diez por ciento) en disolucion en disolventes organicos; y- high quantum yield (approximately ten percent) in solution in organic solvents; Y
- sus superficies son faciles de manipular quirnicamente y pueden incorporarse en matrices organicas.- Its surfaces are easy to handle surgically and can be incorporated into organic matrices.
Se ha acreditado la existencia de un efecto de repelencia fisica motivado por la emision de radiation luminica (luz ultravioleta) en determinadas longitudes de onda que log ran reflejar algunos cristales a nivel micro y nanometrico, como los cristales de oxidos metalicos. Este efecto fisico hasta ahora se ha aprovechado en aplicaciones de bajo desarrollo tecnologico con el empleo de resinas y compuestos inorganicos especificos y se ha desarrollado en diversas invenciones, algunas de ellas plasmadas en patentes como la de Sumitomo Chemical Company (ES2019305).The existence of a physical repellency effect due to the emission of light radiation (ultraviolet light) at certain wavelengths that can reflect some crystals at the micro and nanometric level, such as metal oxide crystals, has been proven. This physical effect has so far been used in applications of low technological development with the use of specific inorganic resins and compounds and has been developed in various inventions, some of them embodied in patents such as Sumitomo Chemical Company (ES2019305).
Estos micro y/o nanocristales ademas proporcionan un mayor anclaje a las microcapsulas confiriendo a estas una mayor persistencia, dando al tejido tratado una mayor efectividad en el tiempo.These micro and / or nanocrystals also provide greater anchorage to the microcapsules, giving them greater persistence, giving the treated tissue greater effectiveness over time.

La microcapsula es una estructura, normalmente de forma esferica, formada por el Iigante de naturaleza diversa (que preferentemente seran compuestos de base acuosa), que es el que envuelve a Ios ingredientes activos. Las microcapsulas, una vez formadas, suelen tener una membrana de 1-5 pm de grosor y un diametro comprendido entre 5-20pm, incluidos ambos limites. Gracias a este pequeno tamario, las microcapsulas ofrecen un area superficial de aplicacion relativamente grande de forma que permite una liberacion uniforme y adecuada de Ios principios activos. El hecho de tener Ios principios activos encapsulados es clave por dos motives fundamentales:The microcapsule is a structure, usually spherically, formed by the Iigant of diverse nature (which will preferably be water-based compounds), which is what surrounds the active ingredients. The microcapsules, once formed, usually have a membrane of 1-5 pm thick and a diameter between 5-20pm, including both limits. Thanks to this small tamarine, the microcapsules offer a relatively large surface area of application in a way that allows a uniform and adequate release of the active ingredients. Having encapsulated active ingredients is key for two fundamental reasons:
- para aislar ingredientes activos que son inestables en contacto con el medio externo;- to isolate active ingredients that are unstable in contact with the external environment;
yY
- para liberar progresivamente estos principios activos.- to progressively release these active ingredients.
Estas microcapsulas y su proceso de obtencion se encuentran descritas en la solicitud de patente internacional WO2011045448 A1. Asi, en la presente invention se pueden microencapsular Ios principios activos repelentes y biocidas mediante diferentes tecnicas que varian dependiendo del principio activo y de su funcionalidad, siendo principalmente: -Coacervacion.These microcapsules and their process of obtaining are described in the international patent application WO2011045448 A1. Thus, in the present invention, the repellent active ingredients and biocides can be microencapsulated by different techniques that vary depending on the active principle and its functionality, being mainly: -Coacervation.

La composicion es de aplicacion facil, duradera, resistente a la liuvia y eficaz. Tambien la envoltura de la microcapsula contribuye a la durabilidad y eficacia de la sustancia activa, protegiendo al principio active y facilitando su difusion.The composition is easy to apply, durable, resistant to rain and effective. Also the microcapsule shell contributes to the durability and effectiveness of the active substance, protecting the active principle and facilitating its diffusion.
Este desarrollo tecnologico, en lo referente al control de vectores, se basa en el empleo de dos efectos combinados de repelencia y accion:This technological development, in relation to vector control, is based on the use of two combined effects of repellency and action:
• Quimico: Fundado en el empleo de sustancias microencapsuladas de origen natural, con potencialidad como repelentes y como biocidas, incluyendo bactericidas y virucidas; y• Chemical: Founded in the use of microencapsulated substances of natural origin, with potential as repellents and as biocides, including bactericides and virucides; Y
• Fisico: Fundado en el empleo de micro y/o nanocristales, dopados o no, capaces de refiejar o emitir radiacion en zonas del ultravioleta que incomodan a los insectos, interfiriendo tambien en su vuelo. Por otra parte, los nano y microcristales de vidrio incluidos en las composiciones que son susceptibles de aplicarse a las prendas textiles, como se vera mas adelante, crean una estructura que dificulta la migracion hacia el exterior de los ingredientes activos, reteniendolos en el tejido y aumentando la persistencia de la eficacia de los mismos.• Physical: Founded on the use of micro and / or nanocrystals, doped or not, capable of refusing or emitting radiation in ultraviolet areas that bother insects, also interfering with their flight. On the other hand, the nano and glass microcrystals included in the compositions that are likely to be applied to textile garments, as will be seen later, create a structure that makes it difficult to migrate the active ingredients outwards, retaining them in the tissue and increasing the persistence of their effectiveness.
La longitud de emision de los cristales de tamano micrometrico y/o nanometrico se puede elegir exactamente seieccionando el diametro adecuado del cristal, sin tener que recurrir a procedimientos de sintesis complicados como los que se requieren para modificar espectro de emision de los componentes organicos.The emission length of the micrometer and / or nanometer size crystals can be chosen exactly by selecting the appropriate diameter of the crystal, without having to resort to complicated synthetic procedures such as those required to modify the emission spectrum of the organic components.
La particula de cristal micro- y/o nanometrico contiene de unos pocos cientos a decenas de millares de atomos los cuales estan dispuestos ordenadamente, siguiendo una estructura cristalina. La forma de estos cristales debe ser tal que minimice la energla libre (tension de superficie). Esto es por lo que los micro- y/o nanocristales son estructuras compactas que se asemejan a esferas tanto como sea posible, y sea permitido por el orden cristalino. Debido a la larga superficie expuesta de los micro y/o nanocristales pueden ser altamente activos (quimicamente) e inestables. Es por esto que se piensa que los micro y/o nanocristales pueden tener un enorme potencial en electronica optica debido a su capacidad de cambiar la longitud de onda de la luz.The micro- and / or nanometric crystal particle contains from a few hundred to tens of thousands of atoms which are arranged neatly, following a crystalline structure. The shape of these crystals should be such that it minimizes free energy (surface tension). This is why micro- and / or nanocrystals are compact structures that resemble spheres as much as possible, and are allowed by the crystalline order. Due to the long exposed surface of the micro and / or nanocrystals they can be highly (chemically) active and unstable. This is why it is thought that micro and / or nanocrystals can have enormous potential in optical electronics due to their ability to change the wavelength of light.

La presente invencion se basa en explotar e! desarrollo de los micro- y/o nanocristales emisores en las longitudes de onda requeridas para repeler a los insectos y su incorporacion a tejidos. E! efecto esta basado en el hecho de que ciertas longitudes de onda en el UV, que son reflejadas o emitidas por algunos compuestos inorganicos, que pueden ser producidos en forma de micro- y/o nanocristales para maximizar su efecto, resultan molestas para insectos como los mosquitos, ya que, la perception de las senales de luz es transportada desde el ojo del insecto por una conexion hasta e! cerebro, donde son procesadas y trasladadas a I centra de reacciones, lo que se traduce en la respuesta que este tiene en su comportamiento, es decir, en la orientation del vuelo y la busqueda de su alimento. La radiation ultravioieta altera el normal comportamiento de los insectos viendose interferida la orientacion del vuelo. Los micro y/o nanocristales seran compuestos que tengan una reflectancia ultravioieta a una longitud de onda inferior a 0,4 pm y que tengan un maximo de reflexion en esta longitud de onda. Esta propiedad mantendra a los mosquitos alejados ya que es una frecuencia de luz muy molesta para su vision,The present invention is based on exploiting e! development of the emitting micro- and / or nanocrystals at the wavelengths required to repel insects and their incorporation into tissues. AND! This effect is based on the fact that certain wavelengths in the UV, which are reflected or emitted by some inorganic compounds, which can be produced in the form of micro- and / or nanocrystals to maximize their effect, are annoying for insects such as mosquitoes, since the perception of the light signals is transported from the eye of the insect by a connection to e! brain, where they are processed and transferred to I centers of reactions, which translates into the response that this has in their behavior, that is, in the orientation of the flight and the search for their food. The ultraviolet radiation alters the normal behavior of the insects seeing the orientation of the flight interfered. The micro and / or nanocrystals will be compounds that have an ultraviolet reflectance at a wavelength of less than 0.4 pm and that have a maximum reflection on this wavelength. This property will keep mosquitoes away as it is a very annoying light frequency for their vision,
Los compuestos organicos y/o inorganicos que cumplen las anteriores condiciones se incluyen dentro de esta invencion. Como ejemplos especificos se pueden incluir pigmentos minerales, talco, oxidos metalicos, hidroxidos metalicos, oxidos mixtos de metal e hidroxidos de metales, y silicatos de metales mixtos tales como compuestos de titanato, los compuestos de zirconio y aluminosilicatos, oxidos e hidroxidos de metales de transition, oxidos de hierro, arcilla natural, sulfuros metalicos y sulfato de bario, entre otros.Organic and / or inorganic compounds that meet the above conditions are included within this invention. Specific examples may include mineral pigments, talc, metal oxides, metal hydroxides, mixed metal oxides and metal hydroxides, and mixed metal silicates such as titanate compounds, zirconium compounds and aluminosilicates, oxides and hydroxides of metals of transition, iron oxides, natural clay, metal sulphides and barium sulfate, among others.
Las ventajas de la composition frente a otros productos similares, y que son susceptibles de aplicarse a prendas textiles con protection anti-insectos son las siguientes:The advantages of the composition over other similar products, and which are likely to be applied to textile garments with anti-insect protection are the following:
® Elevada eficacia, al tratarse de una tecnologia novedosa y totalmente diferente a lo que se ha utilizado hasta la fecha, con un nuevo y complejo modo de accion.

• Larga residualidad y persistences de accion, per la liberation lenta de los activos gracias a las microcapsulas. Con el ernpleo en la composicion de la microencapsulacion se logra una liberacion controlada de los ingredientes activos naturales, as! como una estabiiidad de los mismos a los agentes externos (insolacion, cambios de temperatura), aumentando la vida corta media de estos productos. Ademas, la adicion de micro- y/o nanocristaies a la composicion impide que las sustancias activas puedan salir rapidamente y liberarse al medio ambiente, creando un sistema de liberacion controlada y paulatina de los mismos con lo que su persistencia se ve aumentada.• Long residuality and persistence of action, for the slow release of the assets thanks to the microcapsules. With the use of microencapsulation composition, a controlled release of natural active ingredients is achieved, as well! as their stability to external agents (heat stroke, temperature changes), increasing the average short life of these products. In addition, the addition of micro- and / or nanocrystals to the composition prevents active substances from being able to leave quickly and be released into the environment, creating a system of controlled and gradual release of the same with what their persistence is increased.
® Ausencia de generacion de residuos toxicos, con el consiguiente ahorro y simplification en el manejo y reutilizacion de los materiales. El ernpleo de piretroides sinteticos en composiciones similares provoca que se aporten cantidades importantes de estos insecticidas a cursos de agua dulce y salada, lo que provoca contamination de estas aguas al tratarse de materias activas muy toxicas para la fauna acuatica.® Absence of toxic waste generation, with the consequent saving and simplification in the handling and reuse of materials. The use of synthetic pyrethroids in similar compositions causes significant amounts of these insecticides to be added to fresh and salt water courses, which causes contamination of these waters as they are very toxic active substances for aquatic fauna.

• Viabilidad a largo plazo, al no tener riesgo de aparicion de resistencias, debido a su modo de accion combinado y liberacion sostenida. Con el doble efecto quimico-fisico se evita la aparicion de resistencias, ya que los insectos no pueden desarrollar una resistencia a un metodo de control fisico.• Long-term viability, as there is no risk of resistance, due to its combined mode of action and sustained release. With the double chemical-physical effect, the appearance of resistance is avoided, since insects cannot develop resistance to a physical control method.

El proceso de microencapsulacion de los ingredientes activos biocidas y/o repelentes se encuentra descrito en la solicitud de patente internacional WO2011045448 A1.The microencapsulation process of the biocidal and / or repellent active ingredients is described in the international patent application WO2011045448 A1.
Ejemplo 2: Preparacion in situ de una prenda textil que incorpora la composicion descrita en el Ejemplo 1.Example 2: Preparation in situ of a textile garment incorporating the composition described in Example 1.
La preparacion del tejido se efectuo mediante un tratamiento con la formulacion que incluia los ingredientes activos, los cristales, las ciclodextrinas, los ligantes, fijadores, etc. y posteriormente se seco y se curaron los ligantes para formar una red tridimensional sobre el tejido que atrapaba las microcapsulas y los cristales. Esta impregnacion se realizo en una o varias etapas dependiendo del material del tejido para despues reaiizar el curado.The tissue preparation was carried out by a treatment with the formulation that included the active ingredients, crystals, cyclodextrins, binders, fixatives, etc. and subsequently dried and the binders were cured to form a three-dimensional network on the tissue that trapped the microcapsules and crystals. This impregnation was carried out in one or several stages depending on the material of the tissue to then cure.
Otro mecanismo de impregnacion fue mediante una aplicacion por recubrimiento a una cara con cilindro lamedor o rasqueta.Another impregnation mechanism was by a coating application to a face with a licking cylinder or scraper.
Los cristales en el textil son incluidos en:The crystals in the textile are included in:
1. Una formulacion acuosa que contiene ligantes y fijadores, de modo que el tejido se impregna y posteriormente se seca y curan estos ligantes para formar una red polimerica que los fija al tejido.1. An aqueous formulation containing binders and fixatives, so that the tissue is impregnated and subsequently dried and cured these binders to form a polymeric network that fixes them to the tissue.
2. Igualmente se pueden aplicar a una cara del tejido mediante recubrimiento por medio de un cilindro lamedor o rasqueta.2. They can also be applied to a face of the fabric by coating by means of a licking cylinder or scraper.
3. La otra via de inclusion de los cristales es mediante mezclado en estado fundido con e! polimero sintetico del poliester u otros, para posteriormente hilarlo y tejerlo para3. The other way of including the crystals is by mixing in the molten state with e! synthetic polymer from polyester or others, to later spin and weave it to
5 obtener un tejido con los cristales en la propia masa de la fibra sintetica.5 obtain a fabric with the crystals in the mass of the synthetic fiber.
Ejemplo 3: Pruebas de uso de la prenda textil descrita en el Ejemplo 2.Example 3: Tests of use of the textile garment described in Example 2.
Las prendas confeccionadas con los tejidos tratados se someten a pruebas de eficacia de repelencia tanto acabadas de tratar como tras diferentes lavados.Garments made with treated fabrics are subjected to repellency efficacy tests, both finished and after different washes.
