Banda textil para elemento de proteccion solarTextile band for sun protection element
La presente invencion pertenece al sector textil, mas concretamente al sector textil tecnico.The present invention belongs to the textile sector, more specifically to the technical textile sector.
En la presente invencion, el termino elemento textil o banda textil se utiliza para referirse a tejidos del tipo de calada, es decir, obtenidos a partir del cruce perpendicular de hilos que van en sentido longitudinal (urdimbre) y de hilos que van en sentido transversal (trama). Dichos elementos textiles se producen habitualmente en piezas o bandas rectangulares cuyas dimensiones vienen dadas por la anchura, longitud y espesor de las mismas. La anchura de las bandas viene impuesta por las limitaciones fisicas del telar, por lo cual, la longitud del elemento textil suele ser considerablemente superior a la anchura.In the present invention, the term textile element or textile band is used to refer to fabrics of the type of shedding, that is, obtained from the perpendicular crossing of threads that go longitudinally (warp) and threads that go transversely (plot). Such textile elements are usually produced in rectangular pieces or bands whose dimensions are given by their width, length and thickness. The width of the bands is imposed by the physical limitations of the loom, whereby the length of the textile element is usually considerably greater than the width.
En la presente invencion, el termino elemento de proteccion o elemento de recubrimiento se utiliza para referirse a elementos textiles cuya finalidad es la proteccion de objetos y/o zonas frente a los agentes atmosfericos tales como lluvia, polvo, radiacion solar, etc. Dichos elementos de proteccion suelen recibir la denominacion habitual de lonas o toldos, entre otros. Durante el proceso de confeccion de dichos elementos de recubrimiento, se lleva a cabo uno o varios pliegues de los extremos longitudinales del elemento textil, dichos pliegues, conocidos habitualmente como dobladillo, tienen el objeto de evitar el deshilachado del elemento. La realizacion de dichos pliegues en el elemento textil durante la confeccion de los elementos de proteccion, acarrea la aparicion de zonas con un espesor mayor, es decir, aquellas zonas del elemento de proteccion en las que tiene lugar el pliegue presentan un espesor superior al de las zonas sin pliegue.In the present invention, the term protection element or covering element is used to refer to textile elements whose purpose is the protection of objects and / or areas against atmospheric agents such as rain, dust, solar radiation, etc. These protection elements usually receive the usual name of canvases or awnings, among others. During the process of making said covering elements, one or several folds of the longitudinal ends of the textile element are carried out, said folds, commonly known as hemming, are intended to prevent fraying of the element. The realization of said folds in the textile element during the preparation of the protection elements, causes the appearance of areas with a greater thickness, that is, those areas of the protection element in which the fold takes place have a thickness greater than that of the foldless areas.
Tal como se ha mencionado anteriormente, los elementos textiles se producen habitualmente con dimensiones de anchura impuestas por las limitaciones fisicas del proceso de fabricacion. Por esta razon, durante la confeccion de elementos de recubrimiento que permiten cubrir areas mayores a la anchura del elemento textil, es necesario llevar a cabo la union de varios elementos o bandas textiles. Dicha union se consigue mediante la superposicion parcial de los extremos longitudinales de dos bandas textiles contiguas y su posterior fijacion mediante medios de fijacion permanentes tales como costura o soldadura, entre otros. Como consecuencia de la superposicion de dos elementos textiles, se producen en el elemento de proteccion, zonas con un espesor mayor, es decir, aquellas zonas del elemento de proteccion en las que tiene lugar la superposicion de dos o mas bandas textiles presentan un espesor superior al de aquellas zonas sin superposicion de bandas.As mentioned above, textile elements are usually produced with width dimensions imposed by the physical limitations of the manufacturing process. For this reason, during the preparation of covering elements that allow covering areas larger than the width of the textile element, it is necessary to carry out the union of several textile elements or bands. Said union is achieved by partially overlapping the longitudinal ends of two adjacent textile bands and their subsequent fixation by permanent fixing means such as sewing or welding, among others. As a consequence of the superposition of two textile elements, areas with a greater thickness are produced in the protection element, that is, those zones of the protection element in which the superposition of two or more textile bands takes place have a greater thickness to those areas without overlapping bands.
Los elementos de proteccion de la presente invencion son habitualmente enrollados y desenrollados. Por ejemplo, el elemento de proteccion puede ser desenrollado cuando se desea que ofrezca proteccion contra la lluvia o radiacion solar, y puede ser enrollado en condiciones de fuerte viento para protegerlo de un sobreesfuerzo que pudiera provocar su rotura o el de la estructura que lo sujeta. Tal como ha sido comentado anteriormente, los elementos de proteccion, como consecuencia de su proceso de confeccion, presentan zonas con espesores diferenciados. Debido a esta diferencia de espesor del elemento de proteccion, cuando este se encuentra en la posicion enrollada, las zonas del elemento que presentan un mayor espesor ofrecen un diametro sensiblemente mayor al de las zonas del elemento que tienen un menor espesor. Por esta razon, los hilos de las zonas de menor espesor se ven sometidos a una fuerza de tension constante cuando el elemento de proteccion esta en la posicion enrollada. Dicha fuerza de tension provoca deformaciones permanentes en el elemento de proteccion tales como arrugas y/o bolsas que son percibidas cuando el elemento de proteccion se encuentra enThe protection elements of the present invention are usually rolled and unwound. For example, the protection element can be unwound when it is desired to offer protection against rain or solar radiation, and it can be rolled up in conditions of strong wind to protect it from overexertion that could cause its breakage or that of the structure that holds it . As previously mentioned, the protection elements, as a consequence of their manufacturing process, have areas with different thicknesses. Due to this difference in thickness of the protection element, when it is in the rolled position, the areas of the element that have a greater thickness offer a diameter substantially greater than that of the areas of the element that have a smaller thickness. For this reason, the threads of the areas of smaller thickness are subjected to a constant tension force when the protection element is in the wound position. Said tension force causes permanent deformations in the protection element such as wrinkles and / or bags that are perceived when the protection element is in

Este efecto se produce al cabo de muy poco tiempo de utilizacion del elemento de proteccion, comporta un efecto estetico negativo y puede acelerar la degradacion del mismo.the unwind position. This effect occurs after a very short time of use of the protection element, has a negative aesthetic effect and can accelerate its degradation.
Para solventar la formacion de dichas deformaciones permanente, el documento ES2361564A1 da a conocer un elemento textil de proteccion con capacidad autotensante formado por bandas de tejido que estan constituidas por hilos con propiedades elasticas. Sin embargo, el elemento textil dado a conocer en dicho documento no evita de manera totalmente satisfactoria la aparicion de deformaciones permanentes durante todo el periodo de uso del elemento de proteccion.To solve the formation of said permanent deformations, the document ES2361564A1 discloses a protective textile element with self-tensing capacity formed by bands of fabric that are constituted by threads with elastic properties. However, the textile element disclosed in said document does not completely prevent the appearance of permanent deformations during the entire period of use of the protection element.
En la presente invencion, el termino hilos del tipo “core spun” o hilos “core spun” se utiliza para referirse a aquellos hilos que comprenden un nucleo, tambien llamado alma o “core” y una envolvente tambien llamada vaina o “sheath”. El nucleo de los hilos “core spun” esta formado por uno o varios hilos. Por otro lado, la envolvente esta formada por fibras que recubren el nucleo de los hilos “core spun”. Tal y como es conocido en el estado de la tecnica, el nucleo y la envolvente de los hilos “core spun” puede estar formado por materiales iguales o diferentes. Asimismo, los filamentos que forman el nucleo y/o la envolvente de los hilos “core spun” pueden ser elasticos, rigidos, semirrigidos, entre otros.In the present invention, the term "core spun" or "core spun" threads is used to refer to those threads that comprise a core, also called a core or "core" and an envelope also called a sheath or "sheath." The core of the "core spun" threads is formed by one or more threads. On the other hand, the envelope is formed by fibers that line the core of the core spun threads. As is known in the state of the art, the core and envelope of the "core spun" threads may be formed by the same or different materials. Likewise, the filaments that form the core and / or the envelope of the "core spun" threads can be elastic, rigid, semi-rigid, among others.
Los inventores de la presente invencion, tras rigurosos experimentos han desarrollado un elemento textil que permite superar los problemas de los elementos textiles conocidos en el estado de la tecnica y que resulta sorprendente por presentar una capacidad mejorada de evitar la formacion de arrugas respecto a la conocida en el estado de la tecnica. En particular, la presente invencion da a conocer una banda textil para elementos de proteccion o de recubrimiento constituida por un tejido de calada, constituido por el cruce perpendicular de hilos que van en sentido longitudinal o urdimbre e hilos en sentido transversal o trama, la cual comprende hilos “core spun” que comprenden un nucleo que comprende fibras elastomericas con propiedades viscoelasticas.The inventors of the present invention, after rigorous experiments have developed a textile element that allows to overcome the problems of the textile elements known in the state of the art and which is surprising for presenting an improved ability to avoid the formation of wrinkles with respect to the known in the state of the art. In particular, the present invention discloses a textile band for protection or covering elements constituted by an openwork fabric, constituted by the perpendicular crossing of threads that go in a longitudinal or warp direction and threads in a transverse or weft direction, which it comprises "core spun" threads comprising a core comprising elastomeric fibers with viscoelastic properties.
Por lo tanto, la presente invencion se basa en la utilizacion de bandas textiles constituidas por hilos que comprenden fibras elastomericas. Dichas fibras elastomericas se caracterizan por poseer propiedades viscoelasticas. A diferencia de los materiales que poseen propiedades puramente elasticas, los materiales con propiedades viscoelasticas ofrecen una deformacion dependiente del tiempo. La viscoelasticidad es consecuencia de la reorganizacion molecular del material, concretamente de la reorganizacion de las cadenas polimericas que forman el elastomero en un fenomeno conocido como “creep” o deformacion por fluencia lenta. Cuando un material viscoelastico es sometido a tension, se produce la deformacion por fluencia lenta y el material fluye hasta acomodarse a la nueva situacion de equilibrio. Cuando deja de aplicarse la tension inicial sobre el material, el material recupera la forma original. Dichas propiedades viscoelasticas propias de las fibras elastomericas de la presente invencion son las responsables de la capacidad mejorada que presenta el elemento textil de la presente invencion para evitar la aparicion de arrugas y/o deformaciones permanentes.Therefore, the present invention is based on the use of textile bands consisting of threads comprising elastomeric fibers. Said elastomeric fibers are characterized by having viscoelastic properties. Unlike materials that have purely elastic properties, materials with viscoelastic properties offer a time-dependent deformation. Viscoelasticity is a consequence of the molecular reorganization of the material, specifically the reorganization of the polymer chains that form the elastomer in a phenomenon known as "creep" or slow creep deformation. When a viscoelastic material is subjected to tension, slow creep deformation occurs and the material flows to accommodate the new equilibrium situation. When the initial stress on the material ceases to apply, the material recovers the original form. Said viscoelastic properties of the elastomeric fibers of the present invention are responsible for the improved ability of the textile element of the present invention to prevent the appearance of wrinkles and / or permanent deformations.

Tal como se aprecia en la figura 1, el elemento textil de la presente invencion puede ser utilizado como toldo. Dicho toldo esta formado por la union de las bandas textiles -1-, -2-, etc. Cuando el toldo debe ser recogido, este es enrollado alrededor del cilindro -3- mediante la accion rotatoria de dicho cilindro.As seen in Figure 1, the textile element of the present invention can be used as a canopy. Said awning is formed by the union of textile bands -1-, -2-, etc. When the awning must be collected, it is wrapped around the cylinder -3- by means of the rotating action of said cylinder.
Tal como se aprecia en la figura 2, la union entre las bandas textiles -1- y -2- tiene lugar mediante la superposicion parcial de sus respectivos extremos longitudinales -4- y -5- formando una zona de superposicion -6- que transcurre paralela al eje central longitudinal -7-. En la zona -6- se aplican medios de fijacion permanentes tales como costura o soldadura, entre otros. Debido al mayor espesor del elemento de proteccion en la zona -6-, cuando dicho elemento se encuentra enrollado, se producen tensiones que conllevan la aparicion de las arrugas -8-, -9-, las cuales son apreciadas en la posicion desenrollada del elemento de proteccion.As can be seen in Figure 2, the union between the textile bands -1- and -2- takes place by partially overlapping their respective longitudinal ends -4- and -5- forming an overlapping zone -6- that passes parallel to the central longitudinal axis -7-. In the zone -6- permanent fixing means such as sewing or welding are applied, among others. Due to the greater thickness of the protection element in the area -6-, when said element is wound, tensions occur which lead to the appearance of wrinkles -8-, -9-, which are appreciated in the unwound position of the element of protection.
Tal como se aprecia en la figura 3, los hilos “core spun” que constituyen el elemento textil comprenden un nucleo -10-, tambien llamado alma o “core” y una envolvente -11- tambien llamada vaina o “sheath”. El nucleo -10- comprende una pluralidad de fibras elastomericas, mientras que la envolvente -11-, que recubre al nucleo, comprende una pluralidad de fibras acrilicas.As can be seen in figure 3, the "core spun" threads that constitute the textile element comprise a core -10-, also called a core or "core" and an envelope -11- also called a sheath or "sheath". The core -10- comprises a plurality of elastomeric fibers, while the envelope -11-, which covers the core, comprises a plurality of acrylic fibers.

Tal como se aprecia en la figura 4, el grafico representa el alargamiento bajo carga constante y la recuperacion elastica de una banda textil constituida por hilos “core spun” que comprenden un nucleo que comprende fibras elastomericas. En el eje de abscisas se representa la escala temporal, mientras que en el eje de ordenadas se representa el porcentaje de alargamiento de la banda, calculado segun la formula:As can be seen in Figure 4, the graph represents the elongation under constant load and the elastic recovery of a textile band consisting of "core spun" threads comprising a core comprising elastomeric fibers. The time scale is represented on the abscissa axis, while the band elongation percentage is represented on the ordinate axis, calculated according to the formula:
1010
% alargamiento= [(longitud final - longitud inicial)/longitud inicial] x 100% elongation = [(final length - initial length) / initial length] x 100
En el instante inicial -12- se aplica una fuerza de extension sobre la banda textil, de manera que se produce en dicha banda un alargamiento inicial instantaneo. Despues del instante inicial -12-, se produce el alargamiento de 15 la banda bajo carga constante, dicho alargamiento bajo carga constante aumenta hasta alcanzar un valor constante en torno al instante -13-. En dicho instante -13- se deja de aplicar sobre la banda textil la fuerza de extension, de manera que a partir del instante -13- da comienzo la recuperacion elastica de la banda. Durante la recuperacion elastica, el alargamiento disminuye con el tiempo hasta alcanzar la recuperacion elastica maxima -14- superior al 99%.At the initial moment -12- an extension force is applied on the textile band, so that an instantaneous initial elongation occurs in said band. After the initial moment -12-, the elongation of the band under constant load occurs, said elongation under constant load increases until reaching a constant value around the instant -13-. At that moment -13- the extension force is no longer applied to the textile band, so that from the moment -13- the elastic recovery of the band begins. During the elastic recovery, the elongation decreases with time until reaching the maximum elastic recovery -14- greater than 99%.
