Antecedentes de la invenciónBackground of the invention

En determinados sectores o profesiones, el personal está expuesto a los riegos térmicos de fuego y llama, como por ejemplo en las industrias eléctricas, químicas y petroquímicas, así como los guardas rurales, forestales y personal militar, los cuales especialmente están expuestos a la picadura de vectores, tales como las garrapatas, mosquitos, piojos y pulgas. Es decir, todas aquellas personas que desarrollan su actividad profesional en entornos rurales o forestales, pueden sufrir picadas de vectores.In certain sectors or professions, the personnel are exposed to the thermal risks of fire and flame, such as for example in the electrical, chemical and petrochemical industries, as well as rural, forestry and military personnel guards, which are especially exposed to vector bites, such as ticks, mosquitoes, lice and fleas. That is to say, all those people who develop their professional activity in rural or forest environments, may suffer bites from vectors.

En epidemiología y ecología se llama vector a un mecanismo, generalmente un organismo, que transmite un agente infeccioso o infestante desde los individuos afectados a otros que aún no portan ese agente. Por ejemplo, los mosquitos son los más peligrosos porque entre ellos, hay los que transmiten la malaria y la fiebre amarilla. Las enfermedades se pueden transmitir tanto por picadura o mordedura de los vectores, como por contacto y transferencia de microorganismos patógenos. Hay que tener en cuenta, que los mercados valoran mucho la protección contra las garrapatas, ya que por ejemplo, en el año 2007, en Rusia, murieron como mínimo 26 personas por picadas de garrapatas.In epidemiology and ecology a vector is called a mechanism, usually an organism, that transmits an agent infectious or infesting from affected individuals to others who They don't carry that agent yet. For example, mosquitoes are the most dangerous because among them, there are those that transmit malaria and yellow fever Diseases can be transmitted both by vector sting or bite, such as by contact and transfer of pathogenic microorganisms. Must take into account, that markets highly value tick protection, since for example, in 2007, in Russia, they died at least 26 people per tick bites.

Por lo tanto, el personal que desarrolla estas actividades debe llevar una indumentaria de protección térmica, que repela e incluso mate a los vectores, de una forma no tóxica para el usuario, y que aguante el uso habitual de las prendas, su mantenimiento y sobre todo su lavado. El lavado de las prendas de vestir de estas características es el principal inconveniente, puesto que debilita o resta efectividad a la protección contra los vectores.Therefore, the staff that develops these activities must wear a thermal protection clothing, which repels and even kills vectors, in a non-toxic way to the user, and that endures the usual use of the garments, their maintenance and especially its washing. The washing of the garments of wearing these characteristics is the main drawback, since it weakens or reduces effectiveness to protection against vectors.

Descripción de la invenciónDescription of the invention

El tejido ignífugo anti vectores para la confección de prendas de vestir que la invención propone, resuelve la problemática anteriormente expuesta, al ofrecer una protección térmica junto a una protección contra los vectores duradera, que además confiere al tejido un aspecto y tacto confortable.The flame retardant anti-vector fabric for clothing manufacturing proposed by the invention resolves the problem described above, offering protection thermal together with a long-lasting protection against vectors, which It also gives the fabric a comfortable look and feel.

Para ello, y de forma mas concreta, el tejido ignífugo anti vectores para la confección de prendas de vestir, comprende de fibras de meta-aramida y para- aramida, impregnado con una sustancia repelente de vectores.To do this, and more specifically, the fabric Flame retardant anti-vectors for clothing making, comprises of meta-aramid and para-aramid fibers, impregnated with a vector repellent substance.

Las fibras de meta-aramida son fibras intrínsecamente resistentes a la llama, lo cual significa que las prendas no tendrán limitación de uso frente a los lavados, ya que sus propiedades ignífugas vienen dadas por su estructura molecular, y no en base a ningún tratamiento.The meta-aramid fibers are intrinsically flame resistant fibers, which means that the clothes will not have limitation of use compared to the washes, since its fire retardant properties are given by its structure molecular, and not based on any treatment.

Las fibras de para-aramida dotan al tejido de mejores propiedades mecánicas. Además, permiten que frente a una llama no se rompa, evitando así el contacto directo de la llama con la piel del portador de la prenda.Para-aramid fibers endow to the fabric of better mechanical properties. In addition, they allow in front of a flame do not break, thus avoiding direct contact of the flame with the skin of the wearer of the garment.

Adicionalmente, el tejido puede comprender fibras antiestáticas no metálicas, para conferir a la prenda propiedades antiestáticas.Additionally, the tissue may comprise non-metallic antistatic fibers, to confer on the garment antistatic properties

Por otro lado, y para conferir un mayor confort, adicionalmente el tejido puede comprender viscosa retardante de la llama, para conferir a la prenda propiedades hidrofílicas, es decir, capacidad para absorber rápidamente la humedad generada por el portador de la prenda.On the other hand, and to confer greater comfort, additionally the tissue may comprise viscous retardant of the flame, to confer on the garment hydrophilic properties, is that is, ability to quickly absorb moisture generated by the wearer of the garment.

En cuanto a la protección anti vectores, la sustancia repelente es permetrina, ingrediente activo que repele y/o mata a determinados vectores. Para el caso que nos ocupa repele y/o mata a mosquitos y garrapatas principalmente. Se trata de un producto certificado que garantiza que ninguno de sus componentes son tóxicos, y son inofensivos para la salud humana.As for the anti-vector protection, the repellent substance is permethrin, active ingredient that repels and / or kill certain vectors. In the case at hand, it repels and / or kill mosquitoes and ticks mainly. It's about a certified product that guarantees that none of its components They are toxic, and they are harmless to human health.

Para determinar la cantidad de permetrina debemos tener en cuenta que cada proceso posterior al acabado, tales como ennoblecer el tejido, los lavados de la prenda, el roce al que se somete la prenda, hace que se pierda permetrina. Por tanto, hemos de poner una cantidad suficiente para garantizar la cantidad mínima necesaria para una buena efectividad de la protección anti vectores. La cantidad de permetrina está comprendida entre el 0,5% y el 5% por m^{2} de tejido.To determine the amount of permethrin we must take into account that each post-finishing process, such as ennoble the fabric, the washings of the garment, the rubbing to which the garment is submitted, causes permethrin to be lost. By therefore, we have to put a sufficient amount to guarantee the minimum amount necessary for good effectiveness of the vector protection. The amount of permethrin is between 0.5% and 5% per m2 of tissue.

La cantidad de fibras de meta-aramida está comprendida entre el 35% y el 95%, y la cantidad de fibras de para-aramida está comprendida entre el 2% y el 60%.The amount of fibers of meta-aramid is between 35% and 95%, and the amount of para-aramid fibers is between 2% and 60%.

En el caso de incorporar fibras antiestáticas, éstas estarán comprendidas entre el 0% y el 5%, y en el caso de la viscosa retardante de la llama estarán comprendida entre el 0% y el 63%.In the case of incorporating antistatic fibers, these will be between 0% and 5%, and in the case of flame retardant viscose will be between 0% and 63%

El procedimiento de impregnación del tejido ignífugo anti vectores para la confección de prendas de vestir con la sustancia repelente se realiza mediante impregnación por foulard, y un posterior termofijado en horno continuo. La impregnación por foulard consiste en hacer pasar el tejido ignífugo por un baño con la solución de la sustancia repelente, y después por un juego de rodillos para prensar y extraer la sustancia repelente sobrante.The tissue impregnation procedure Flame retardant anti-vector for making garments with the repellent substance is made by impregnation by foulard, and a subsequent thermofixed in continuous oven. Impregnation by Foulard consists of passing the fire retardant fabric through a bath with the solution of the repellent substance, and then by a set of rollers for pressing and extracting the repellent substance surplus.

El termofijado en horno continuo se realiza a una temperatura comprendida entre 100ºC y 190ºC, durante un período de tiempo comprendido entre 20 segundos y 60 segundos.Thermosetting in continuous furnace is done at a temperature between 100ºC and 190ºC, during a period of time between 20 seconds and 60 seconds.

Para esta investigación, las garrapatas "Ixodes ricinus" (L.) hembras y machos, fueron tomadas del laboratorio de cultivo. Se contaron unos discos del tejido a testar (70 mm diámetro) y se colocaron en la parte inferior de la placa de vidrio de Petri. Los tratamientos fueron uno de control (con papel de filtro) y otro con la muestra a testar (tejido basado en fibras de meta-aramida y para-aramida, y mezclas con otras fibras impregnado en Permetrina, lavado 20 veces). Las garrapatas "Ixodes ricinus" (L.) machos y hembras fueron colocadas sobre las muestras de tejidos durante la fotofase, las placas Petri fueron cerradas, y el número de garrapatas derribadas y muertas fueron evaluadas después de 10 minutos, 120 minutos y 24 horas.For this investigation, female and male " Ixodes ricinus " (L.) ticks were taken from the culture laboratory. Disks of the tissue to be tested (70 mm diameter) were counted and placed at the bottom of the Petri glass plate. The treatments were one of control (with filter paper) and another with the sample to be tested (fabric based on meta-aramid and para-aramid fibers, and mixtures with other fibers impregnated in Permethrin, washed 20 times). The " Ixodes ricinus " (L.) male and female ticks were placed on the tissue samples during the photophase, the Petri dishes were closed, and the number of knocked down and dead ticks were evaluated after 10 minutes, 120 minutes and 24 hours .

Comparaciones de los ratios de derribos y mortalidad entre tratamiento y control en intervalos discretos fueron realizados utilizando exactamente el ensayo de Fisher. Durante los periodos de observación las garrapatas permanecieron en contacto con las muestras del tejido. En el control no tratado, tres hembras fueron encontradas excepcionalmente en el vidrio bajo de la cubierta de la placa de Petri.Comparisons of demolition ratios and mortality between treatment and control at discrete intervals They were performed using exactly Fisher's essay. During the observation periods the ticks remained in contact with tissue samples. In the untreated control, three females were found exceptionally in the low glass of the petri dish cover.

Los resultados del ensayo mostraron un fuerte efecto de derribo y incremento de la mortalidad sobre las garrapatas "Ixodes ricinus" (L.) adultos conforme el tiempo pasaba. Un fuerte efecto de derribo fue observado en el periodo entre los 10 y 120 minutos, y el incremento de mortalidad fue registrado durante las 2 y 24 horas. Después de 24 horas, todos los machos y hembras murieron (P-Fisher \leq 0,0001 comparado con el papel de filtro sin tratamiento). Sobre el papel de filtro no fueron observados efectos de derribo ni de mortalidad durante las 24 horas del ensayo.The results of the trial showed a strong effect of demolition and increased mortality on ticks " Ixodes ricinus " (L.) adults as time went by. A strong demolition effect was observed in the period between 10 and 120 minutes, and the increase in mortality was recorded during 2 and 24 hours. After 24 hours, all males and females died (P-Fisher? 0.0001 compared to filter paper without treatment). No effects of demolition or mortality were observed on the filter paper during the 24 hours of the trial.
