Para ese proposito, la fibra de monofilamento extrudida fabricada con poliolefinas en poliuretano, tiene una cierta seccion transversal y la altura de las fibras que forman las alfombras de cesped presentan una cierta longitud. De esta manera, las fibras que forman la alfombra de cesped artificial se permite que recuperen su posicion vertical despues de sido sometidas a cargas sucesivas.  The following invention, according to what is expressed in the statement herein, refers to an artificial grass fiber, which is of the type of fibers used in the manufacture of artificial grass carpets, weaving the fibers, thereby that the essential objective is to obtain a fiber with some elastic characteristics which make it recover its vertical position after being compressed, occasionally or temporarily, maintaining its original appearance for a long time. For this purpose, the extruded monofilament fiber made of polyolefins in polyurethane has a certain cross-section and the height of the fibers that form the grass mats have a certain length. In this way, the fibers that make up the artificial grass carpet are allowed to regain their vertical position after being subjected to successive loads.

Campo de aplicacion Scope

En la presente memoria, se describe una fibra para cesped artificial, de aplicacion especial en la fabricacion de alfombras de fibra artificial para cesped en la instalacion de campos para diferentes deportes, tales como futbol, golf, rugby o hockey. Del mismo modo, la fibra para cesped artificial se aplica igualmente en otras utilizaciones, tales como jardines, caminos de acceso o decoracion.   Herein, a fiber for artificial grass is described, of special application in the manufacture of artificial fiber rugs for lawn in the installation of fields for different sports, such as soccer, golf, rugby or hockey.   Similarly, artificial grass fiber is also applied in other uses, such as gardens, access roads or decoration.  

Antecedentes de la invencion Background of the invention

Como es conocido, cada dia existen mas organizaciones y clubs deportivos que optan por proporcionar a sus instalaciones, campos de juego para diferentes deportes, con cesped artificial como una alternativa al cesped de hierba natural puesto que requiere menos mantenimiento y ofrece una sensacion similar a la del cesped de hierba natural y presenta mejoras, tales como que un campo de cesped artificial puede ser utilizado durante todo el ano y los campos de cesped de hierba natural requieren un periodo de recuperacion en el cual no pueden ser utilizados. Estas alfombras de cesped artificial se fabrican tejiendo fibras artificiales. Por otra parte, con el objetivo de obtener alfombras de cesped artificial con fibras que mantengan sus caracteristicas a lo largo del tiempo, las fibras de monofilamento deben tener una alta elasticidad lo que hace que recuperen su posicion vertical despues de haber sido comprimidas ocasional o temporalmente durante un tiempo, evitando que las fibras permanezcan inclinadas sobre el terreno. De esta manera, se ha intentado obtener fibras fabricadas de diferentes materiales y secciones con el objeto de proporcionarles una alta elasticidad, habiendo considerado los documentos de patentes US n° 6.432.505; EP 1 837 423 y PCT WO 2005/005731. De este modo, en la patente americana US n° 6.432.505, se describe un cesped sintetico que presenta un sustrato y una pluralidad de filamentos del cesped realizados en polimero sintetico anclado en el sustrato, estando dichos filamentos provistos de una seccion transversal en forma de rombo, con un eje longitudinal a lo largo desde un extremo hasta el otro extremo y un eje lateral colocado en el medio de modo que el grosor del filamento gradualmente disminuye desde dicho eje lateral, sustancialmente, simetrica y suavemente sobre el eje longitudinal hacia cada extremo. La patente europea EP 1 837 423, describe un cesped sintetico que comprende un alfombra de cesped y algunos nudos que se prolongan desde la misma, comprendiendo los nudos hilos de filamento individual y por lo menos un hilo deshilachado y, por lo menos, un numero de dichos hilos consiste esencialmente en una mezcla de polietileno de alta densidad y polietileno lineal de baja densidad. En la patente PCT WO 2005/005731, se describe un filamento de cesped artificial en el que el filamento presenta, en seccion transversal, un area central y dos superficies de soporte en lados opuestos de dicha area central y con una orientacion divergente, de tal modo que se forma una cabeza que sobresale hacia fuera en un lado de las areas divergentes del area central y en el lado alejado de las areas divergentes, el area central, presenta una cara la cual esta esencialmente alineada en el lugar de dicha area central y la cual se combina con las caras adyacentes de cada superficie de soporte.  As is known, every day there are more organizations and sports clubs that choose to provide their facilities, playgrounds for different sports, with artificial grass as an alternative to natural grass grass since it requires less maintenance and offers a sensation similar to the of natural grass grass and presents improvements, such as that an artificial grass field can be used throughout the year and natural grass grass fields require a recovery period in which they cannot be used. These artificial grass rugs are made by weaving artificial fibers. On the other hand, in order to obtain artificial grass mats with fibers that maintain their characteristics over time, the monofilament fibers must have a high elasticity which causes them to recover their vertical position after they have been compressed occasionally or temporarily for a while, preventing the fibers from leaning on the ground. In this way, attempts have been made to obtain fibers made of different materials and sections in order to provide them with a high elasticity, having considered US Patent Nos. 6,432,505; EP 1 837 423 and PCT WO 2005/005731. Thus, in US Patent No. 6,432,505, a synthetic grass is described having a substrate and a plurality of grass filaments made of synthetic polymer anchored in the substrate, said filaments being provided with a cross-section in shape. of rhombus, with a longitudinal axis along from one end to the other end and a lateral axis placed in the middle so that the thickness of the filament gradually decreases from said lateral axis, substantially, symmetrically and smoothly on the longitudinal axis towards each extreme. European Patent EP 1 837 423 describes a synthetic grass comprising a grass carpet and some knots that extend therefrom, the knots comprising individual filament threads and at least one frayed thread and at least one number of said threads essentially consists of a mixture of high density polyethylene and linear low density polyethylene. In PCT patent WO 2005/005731, an artificial grass filament is described in which the filament has, in cross section, a central area and two supporting surfaces on opposite sides of said central area and with a divergent orientation, of such so that a head is formed that projects outwardly on one side of the divergent areas of the central area and on the side away from the divergent areas, the central area has a face which is essentially aligned in the place of said central area and which is combined with the adjacent faces of each support surface.

Descripcion de una forma de realizacion preferida Description of a preferred embodiment

Dado que la elasticidad de las fibras que forman las alfombras para el cesped artificial esta afectada tanto por su seccion como por la altura de las fibras que la forman, con objeto de obtener una fibra para cesped artificial con alta elasticidad que facilite su recuperacion contra cargas sucesivas ocasionales o temporales y mantenga su aspecto original, una serie de muestras de fibras de diferentes secciones han sido analizadas a fin de obtener la fibra que presente una elasticidad mas alta. Since the elasticity of the fibers that form the carpets for the artificial grass is affected both by its section and by the height of the fibers that form it, in order to obtain a fiber for artificial grass with high elasticity that facilitates its recovery against loads Occasional or temporary successive and maintain its original appearance, a series of fiber samples from different sections have been analyzed in order to obtain the fiber that has a higher elasticity.

De este modo, teniendo en cuenta que tanto la altura de las fibras que forman las alfombras para cesped artificial como su seccion afecta a la recuperacion de las mismas, esto es su elasticidad y utilizando el procedimiento descrito en la patente de invencion P200930107, en donde se describe un procedimiento para la determinacion del grado de recuperacion en alfombras de fibras artificiales, se ha llevado a cabo un analisis a fin de evaluar la recuperacion de las fibras con diferentes secciones, para lo cual se determina el indice de recuperacion asi como la velocidad de recuperacion, de modo que este parametro senala la velocidad a la cual el material se recupera despues de haber sido liberado de una carga. Thus, taking into account that both the height of the fibers that form the rugs for artificial grass and their section affect their recovery, this is their elasticity and using the procedure described in the invention patent P200930107, where A procedure for determining the degree of recovery in carpets of artificial fibers is described, an analysis has been carried out in order to evaluate the recovery of the fibers with different sections, for which the recovery index is determined as well as the speed of recovery, so that this parameter indicates the speed at which the material recovers after being released from a load.

A partir de estas premisas, han sido analizadas cuatro muestras de alfombras de cesped artificial, con fibras de diferentes secciones que estan realizadas en polietileno extrudido de monofilamento y las fibras que forman las alfombras tienen una altura de 60 mm, siendo una de las muestras la fibra objeto de la invencion con una cierta seccion la cual le confiere alta elasticidad. From these premises, four samples of artificial grass carpets have been analyzed, with fibers of different sections that are made of extruded monofilament polyethylene and the fibers that form the carpets have a height of 60 mm, one of the samples being fiber object of the invention with a certain section which gives it high elasticity.

De este modo, la seccion de la fibra objeto de la invencion ha sido sometida a un analisis junto con tres muestras mas de diferentes secciones, de modo que la seccion transversal de la fibra 1 objeto de la invencion (que corresponde a la muestra de seccion 3) presenta una forma general rectangular plana con sus lados mas cortos redondeados, estando en la parte central de una de sus caras mas largas provista de un saliente curvado convexo 2 y en su otra cara mas larga provista de un par de salientes curvados -convexos 3 en una posicion simetrica con respecto a su eje central. Thus, the section of the fiber object of the invention has been subjected to an analysis together with three more samples of different sections, so that the cross-section of the fiber 1 object of the invention (corresponding to the section sample 3) it has a flat rectangular general shape with its shorter rounded sides, being in the central part of one of its longer faces provided with a convex curved projection 2 and on its other longer face provided with a pair of curved-convex projections 3 in a symmetrical position with respect to its central axis.

De esta manera, la seccion especial de la muestra 3 basada en los salientes curvados convexos de sus caras mas largas le confieren alta elasticidad en la cual colabora la altura de la fibra que forma las alfombras de cesped artificial. In this way, the special section of the sample 3 based on the convex curved projections of its longer faces give it high elasticity in which the height of the fiber that forms the artificial grass mats collaborates.

Ademas, en una forma de realizacion preferida de la fibra 1 para la formacion de alfombras de cesped artificial, presenta un ancho �D� de aproximadamente 1.400 !m. Furthermore, in a preferred embodiment of fiber 1 for the formation of artificial grass carpets, it has a width �D� of approximately 1,400 µm.

Por otra parte, el grosor �d� de la fibra para cesped artificial en la parte central de los salientes curvados convexos es el mismo en todas ellos, de modo que en una forma de realizacion preferida es de aproximadamente 270 !m. On the other hand, the thickness �d� of the artificial grass fiber in the central part of the convex curved projections is the same in all of them, so that in a preferred embodiment it is approximately 270 µm.

De este modo, como se observa en la figura 2 de los dibujos, las fibras 1 que forman los haces tejidos de la alfombra de cesped artificial, presentan una altura preferiblemente de 60 mm, aunque, logicamente, la altura podria ser cualquier otra. Thus, as seen in Figure 2 of the drawings, the fibers 1 that form the woven beams of the artificial grass carpet have a height preferably of 60 mm, although, logically, the height could be any other.

Como se cita en la patente P200930107, el procedimiento se especifica basandose en la aplicacion a las muestras de una fuerza compresiva constante de 1.400 kg durante 72 horas, de modo que, una vez ha pasado este tiempo, la carga se libera y se capturan las imagenes de la misma zona despues de 1, 30 y 240 minutos. Antes de la aplicacion de la fuerza compresiva, tambien se ha tomado una imagen a fin de conocer y definir el area total ocupada por las fibras, correspondiendo este valor a 100� de las fibras en su estado de equilibrio. As cited in patent P200930107, the procedure is specified based on the application to the samples of a constant compressive force of 1,400 kg for 72 hours, so that, once this time has elapsed, the load is released and the images of the same area after 1, 30 and 240 minutes. Before the application of the compressive force, an image has also been taken in order to know and define the total area occupied by the fibers, this value corresponding to 100� of the fibers in their equilibrium state.

Las imagenes capturadas se analizan para cada uno de los tiempos y se calcula el area ocupada por las fibras, asignando el 100� de recuperacion al area inicial ocupada por las fibras antes de la aplicacion de la carga de modo que el calculo del indice de recuperacion se lleva a cabo aplicando la siguiente relacion� The captured images are analyzed for each one of the times and the area occupied by the fibers is calculated, assigning the recovery 100� to the initial area occupied by the fibers before the application of the load so that the calculation of the recovery index It is carried out by applying the following relationship�

�rea despues de la liberacion de la carga (mm2)Area after cargo release (mm2)

�ndice de recuperacion (�) � x 100 Recovery rate (�) � x 100

�rea sin carga (mm2) Unloaded area (mm2)

De este modo, aplicando la metodologia descrita, han sido obtenidos los resultados del indice de recuperacion para las alfombras formadas de algunas fibras con una altura de 60 mm, representado en la tabla de la figura 3, despues de un tiempo de 1, 30 y 240 minutos de ser liberadas de la carga, pudiendo observar como la muestra de seccion 3 presenta un indice de recuperacion del 100� ya a los 30 minutos de la liberacion de la carga. Thus, applying the described methodology, the results of the recovery index have been obtained for the carpets formed of some fibers with a height of 60 mm, represented in the table of figure 3, after a time of 1, 30 and 240 minutes of being released from the cargo, being able to observe how section sample 3 presents a recovery rate of 100� already 30 minutes after the cargo is released.

Del mismo modo, en la figura 3 de los dibujos, se observa la evolucion del indice de recuperacion en las cuatro muestras analizadas a una altura de la fibra de 60 mm, de modo que una vez se ha alcanzado el tiempo estacionario (240 mm), la recuperacion aumenta considerablemente alcanzando, en las muestras objeto de la invencion, dicho valor. Similarly, in Figure 3 of the drawings, the evolution of the recovery index is observed in the four samples analyzed at a fiber height of 60 mm, so that once the stationary time (240 mm) has been reached , the recovery increases considerably reaching, in the samples object of the invention, said value.

En la figura 4 de los dibujos, se describe la clasificacion del resultado obtenido a partir de las cuatro muestras analizadas, pudiendose observar como las fibras de la muestra 3 objeto de la invencion son las que mas se recuperan, estando provistas logicamente, de la elasticidad mas alta. In figure 4 of the drawings, the classification of the result obtained from the four samples analyzed is described, being able to observe how the fibers of the sample 3 object of the invention are the ones that are most recovered, being logically provided, of the elasticity highest.

Por ultimo, en la figura 5 de los dibujos se describe la evolucion del indice de recuperacion de las cuatro muestras analizadas a una altura de las fibras de 60 mm, pudiendose observar como la muestra 3 objeto de la invencion es la que presenta un indice de recuperacion mas grande. Finally, in Figure 5 of the drawings the evolution of the recovery index of the four samples analyzed at a height of 60 mm fibers is described, being able to observe how the sample 3 object of the invention is the one that presents an index of biggest recovery.

De esta manera, se concluye que una fibra 1 para la formacion de alfombras para cesped artificial con una seccion transversal general rectangular con sus lados mas cortos redondeados y en la parte central de sus caras mas largas provistas de un saliente curvado convexo 2 y en su otra cara mas larga provista de un par de salientes curvados convexos 3 en una posicion simetrica con respecto a su eje central, presenta alta resistencia haciendo que las fibras que forman las alfombras de cesped artificial recuperen su posicion vertical despues de haber sido sometidas a algunas cargas compresivas sucesivas y haciendo que mantengan su aspecto estetico original a lo largo del tiempo. In this way, it is concluded that a fiber 1 for the formation of rugs for artificial grass with a rectangular general cross section with its shorter rounded sides and in the central part of its longer faces provided with a convex curved projection 2 and in its another longer face provided with a pair of convex curved projections 3 in a symmetrical position with respect to its central axis, has high resistance making the fibers that form the artificial grass mats recover their vertical position after having been subjected to some loads Compressive successive and making them maintain their original aesthetic appearance over time.

En una forma de realizacion preferida de la fibra 1 para la formacion de alfombras de cesped artificial, presenta un ancho �D� de aproximadamente 1400 !m. In a preferred embodiment of fiber 1 for the formation of artificial grass carpets, it has a width �D� of approximately 1400 µm.

Por otra parte, el grosor �d� de la fibra para cesped artificial en la parte central de los salientes curvados convexos es el mismo para todas ellas, de modo que en una forma de realizacion preferida es de aproximadamente 270 !m. On the other hand, the thickness �d� of the artificial grass fiber in the central part of the convex curved projections is the same for all of them, so that in a preferred embodiment it is approximately 270 µm.
