It is worth mentioning Patent US5858054 "KNITTED PROTECTIVE FABRIC AND GARMENTS MADE THEREFROM", in the name of Mr. Arthur ROSEN, from 1997, which refers to protective knitted fabrics and garments made with them, comprising a protective fabric and garments made from it, which have superior resistance to wear and abrasion, as well as good flexibility and stretchability that allow the fabric to mold itself to the structure that it is intended to protect. Knitted fabric and garments made therefrom comprise a monofilament polymer having a gauge of 0.03 to 0.08 inches interwoven to form a structure of repeating interconnected loops or spirals. The structure may have a honeycomb-like appearance. The monofilament polymer can be a material selected from the group consisting of polyamide, Teflon, polyester, or viscose. Also noteworthy is Patent EP1585853 “BI-DIRECTIONAL AND MULTI-AXIAL FABRICS AND FABRIC COMPOSITES”, dated 2003, in the name of FIONEYWELL INT INC, which refers to bidirectional and multi-axial fabrics, composite fabrics, ballistically resistant assemblies thereof and the methods by which they are made. The fabrics are composed of sets of substantially parallel, unidirectional yarns lying in parallel planes, one above the other, with the direction of the yarns in a given plane rotated at an angle to the direction of the yarns in adjacent planes; and one or more sets of cords having lower strength and higher elongation intertwined with the strong cords. The fabrics of the invention provide superior ballistic efficiency compared to ordinary woven and knitted fabrics, yet retain ease of manufacture on conventional looms and knitting machines. The patent WO2018097737 "THREE-DIMENSIONAL, 3D, KNITTED FABRIC, AND METHOD OF MANUFACTURING SAME", of the year 2017, in the name of GRANBERG AS, belongs to the state of the art, where the three-dimensional fabric comprises an upper layer, a lower layer and an intermediate layer, where the upper layer and the lower layer are joined by transversal threads constituting the intermediate layer, and where at least the upper layer comprises a cut of two resistant folds-threads.

BREVE DESCRIPCIÓN DE LA INVENCIÓN Finally, it is worth highlighting the Patent US10895437 "BALLISTIC UNDERWEAR", in the name of BLUECHER GMBH, of the year 2013, which refers to ballistic underwear, where the area of the base of the underwear is made up of UHMWPE knitwear. resistant to shrapnel and at least one other different textile material. The UHMWPE knitted fabric is arranged in a first zone of the base area. Noteworthy is Figure 16 in which a fabric is made by combining a first interlock pass, a second discontinuous bead pass to the lower needles, a third interlock pass the same as the previous one (on the same needles) and a fourth interlock pass dashed bead on upper needles. BRIEF DESCRIPTION OF THE INVENTION
La presente invención se enmarca dentro del sector de los tejidos que protegen sobre cortes o impactos. The present invention falls within the sector of fabrics that protect against cuts or impacts.
El documento más cercano es la Patente US10895437. The closest document is Patent US10895437.
Dicha patente soluciona el problema de poder combinar un hilo de UHMWPE con otro de otra tipología. Said patent solves the problem of being able to combine a UHMWPE thread with another of another type.
Por otro lado, tiene el inconveniente de que debido a las características del UHMWPE, precisa de combinar con otro hilo para obtener características de transpirabilidad y permeabilidad al aire, perdiendo con ello eficacia su protección. On the other hand, it has the disadvantage that due to the characteristics of UHMWPE, it needs to be combined with another thread to obtain characteristics of breathability and air permeability, thus losing its protection effectiveness.
Además, las cámaras de aire que se crean cuando se une el hilo con pasada de interlock, con el hilo con pasada de cordón y la posterior pasada de interlock, crea unas pequeñas cámaras de corte triangular, que obligan a emplear otros hilos para aumentar la transpirabilidad y el confort. In addition, the air chambers that are created when the thread with the interlock pass is joined, with the thread with the cord pass and the subsequent interlock pass, create small triangular cut chambers, which make it necessary to use other threads to increase the breathability and comfort.
La presente invención soluciona los anteriores inconvenientes mediante un método que dispone las pasadas de interlock y de cordón en distinto orden y unidas de manera diferente a las propuestas en el documento más cercano. The present invention solves the previous drawbacks by means of a method that arranges the interlock and cord passes in a different order and joined in a different way from those proposed in the closest document.
Así, las dos pasadas consecutivas de interlock, la de delante y la de atrás, se unen a las pasadas de cordón (la de delante y la de atrás respectivamente), y no a la anterior interlock como en el documento más cercano. Thus, the two consecutive interlock passes, the front and the back, are joined to the bead passes (the front and the back respectively), and not to the previous interlock as in the closest document.
Además, mientras que en el documento más cercano las pasadas de interlock son siempre sobre las mismas agujas, en la presente invención las pasadas de interlock son alternativas, ocupando los espacios de agujas que no ha ocupado la anterior pasada de interlock, lo que permite aumentar la resistencia del tejido final, ya que siempre hay un hilo cruzado bloqueando los espacios libres In addition, while in the closest document the interlock courses are always on the same needles, in the present invention the interlock courses are alternate, occupying the needle spaces that have not been occupied. the previous interlock pass, which increases the resistance of the final fabric, since there is always a crossed thread blocking the free spaces
Además, las cámaras de aire que se forman tienen corte rectangular o cuadrangular, aumentando su capacidad, y permitiendo que el tejido tenga protección térmica, frío/calor. In addition, the air chambers that are formed have a rectangular or quadrangular cut, increasing their capacity, and allowing the fabric to have thermal, hot/cold protection.

CONCRETA REALIZACIÓN DE LA PRESENTE INVENCIÓN CONCRETE PERFORMANCE OF THE PRESENT INVENTION
A título preliminar, cuando se emplean las expresiones “delante” y “detrás”, se refieren a la posición de las agujas en la máquina tricotosa. Las de delante, agujas delanteras 21, son las que quedan en primer plano, a la vista, las de detrás, agujas traseras 22, son las que están enfrentadas a las agujas delanteras 21 y pueden quedar parcialmente cubiertas, como se puede observar en las figuras 1 a 4. As a preliminary, when the expressions "in front" and "behind" are used, they refer to the position of the needles in the knitting machine. The ones in front, front needles 21, are the ones that remain in the foreground, visible, the ones behind, rear needles 22, are those that face the front needles 21 and can be partially covered, as can be seen in the pictures. figures 1 to 4.
Las figuras 1 a 4 y 6 a 7 se deben siempre interpretar a la vista de la Figura 5 y de la Figura 8. Figures 1 to 4 and 6 to 7 should always be interpreted in light of Figure 5 and Figure 8.
En la Figura 1 se ¡lustra una primera pasada de interlock con un primer hilo 11 , unas agujas delanteras 21 y unas agujas traseras 22 y unas agujas libres 23,24. Figure 1 illustrates a first interlock pass with a first thread 11, front needles 21 and rear needles 22 and free needles 23,24.
En la Figura 2 se muestra la primera pasada de interlock con el primer hilo 11 , las agujas delanteras 21 , las agujas traseras 22, las agujas libres de la primera pasada 23,24 y una segunda pasada de interlock con un segundo hilo 12. Figure 2 shows the first interlock pass with the first thread 11, the front needles 21, the rear needles 22, the free needles of the first pass 23,24 and a second interlock pass with a second thread 12.
En la Figura 3 se representa la primera pasada de interlock con el primer hilo 11 , las agujas delanteras 21, las agujas traseras 22, la segunda pasada de interlock con el segundo hilo 12 y una primera pasada de cordón desagujado con un tercer hilo 13 que deja una aguja libre 25. Figure 3 represents the first interlock pass with the first thread 11, the front needles 21, the rear needles 22, the second interlock pass with the second thread 12 and a first unneedled lace pass with a third thread 13 that leaves a free needle 25.
En la Figura 4 se ha dibujado la primera pasada de interlock con el primer hilo 11, las agujas delanteras 21, las agujas traseras 22, la segunda pasada de interlock con el segundo hilo 12, la primera pasada de cordón desagujado con el tercer hilo 13 que deja una aguja libre 25 y una ocupada 27 y una segunda pasada de cordón desagujado con un cuarto hilo 14 que deja una aguja libre 26 y una ocupada 28. Así en la figura 5 se ¡lustra la primera pasada de interlock 1 , la segunda pasada de interlock 2, la primera pasada de cordón desagujado 3, la segunda pasada de cordón desagujado 4, una tercera pasada de interlock 5, una cuarta pasada de interlock 6, una tercera pasada de cordón desagujado 7, una cuarta pasada de cordón desagujado 8, el primer hilo 11, el segundo hilo 12, el tercer hilo 13, el cuarto hilo 14, un quinto hilo 15, un sexto hilo 16, un séptimo hilo 17 y un octavo hilo 18. En la figura 6 se muestra el primer hilo 11, el segundo hilo 12, el tercer hilo 13, el cuarto hilo 14, el quinto hilo 15, el sexto hilo 16, el séptimo hilo 17 y el octavo hilo 18. Figure 4 shows the first interlock course with the first thread 11, the front needles 21, the rear needles 22, the second interlock course with the second thread 12, the first unneedled cord course with the third thread 13 that leaves a free needle 25 and a busy one 27 and a second pass of unneedled cord with a fourth thread 14 that leaves a free needle 26 and a busy one 28. Thus, figure 5 shows the first pass of interlock 1, the second pass of interlock 2, the first pass of unneedled cord 3, the second pass of unneedled cord 4, a third pass of interlock 5, a fourth pass of interlock 6, a third row of unneedled cord 7, a fourth row of unneedled cord 8, the first thread 11, the second thread 12, the third thread 13, the fourth thread 14, a fifth thread 15, a sixth thread 16, a seventh thread 17 and an eighth thread 18. Figure 6 shows the first thread 11, the second thread 12, the third thread 13, the fourth thread 14, the fifth thread 15, the sixth thread 16, the seventh thread 17 and the eighth thread 18.

Figure 7 shows the first thread 11, the second thread 12, the third thread 13, the fourth thread 14, the fifth thread 15, the sixth thread 16, the seventh thread 17 and the eighth thread 18.
Por último, en la figura 8 se ha dispuesto de manera esquemática la posición de las agujas bajo las letras A, B, C, y D, para una mejor explicación del funcionamiento de las mismas con posterioridad. Finally, in figure 8 the position of the needles has been schematically arranged under the letters A, B, C, and D, for a better explanation of their operation later.
Aun cuando aparezcan ocho hilos distintos 11 a 18 indicados tanto en la descripción, en las reivindicaciones, y en los dibujos, se hace a efectos de claridad en la explicación, para poder explicar cada una de las pasadas del hilo, ya que habitualmente será el mismo hilo (y no ocho hilos) el que hará todas las pasadas. Por ello, a efectos únicamente explicativos se indican ocho hilos, cuando en realidad es el mismo. Even when eight different threads 11 to 18 appear, indicated both in the description, in the claims, and in the drawings, it is done for purposes of clarity in the explanation, to be able to explain each of the thread passes, since it will usually be the same thread (and not eight threads) that will make all the passes. Therefore, for explanatory purposes only eight threads are indicated, when in reality it is the same.
Así, en el método para la fabricación de un tejido anticorte y antipunzante se parte de una estructura de punto lleno, con una galga de entre 5 y 23, en una máquina tricotosa. La diferencia en la galga radica en que a número mayor de galga se consigue que el tejido resultante sea más ligero, más transpirable, sea más ajustable y cómodo de llevar, pero por el contrario el precio de un hilo de galga 23 es muy superior a un hilo de galga 5, que sería todo lo contrario a lo antes indicado, pero con un hilo de galga 5 primaría con ello la fabricación a bajo coste, pudiendo obtener un producto final muchísimo más barato que con galga 23. Por ello, el inventor ha encontrado un punto intermedio entre máximo confort a un precio razonable, con una galga 16 a 400 deniers, pero teniendo en cuenta, que dependiendo del interesado, del confort que se busque, si se prima o no la opción económica, se puede vahar la galga, obteniendo como resultado el tejido objeto del presente método e invención. Thus, in the method for manufacturing an anti-cut and anti-puncture fabric, the starting point is a full stitch structure, with a gauge of between 5 and 23, in a knitting machine. The difference in the gauge is that a higher gauge number makes the resulting fabric lighter, more breathable, more adjustable and comfortable to wear, but on the contrary, the price of a 23 gauge thread is much higher than a 5 gauge thread, which would be the complete opposite of what was indicated above, but with a 5 gauge thread, low-cost manufacturing would prevail, being able to obtain a final product much cheaper than with a 23 gauge. For this reason, the inventor has found an intermediate point between maximum comfort at a reasonable price, with a gauge from 16 to 400 deniers, but taking into account that depending on the person concerned, the comfort sought, whether or not the economic option prevails, one can choose the gauge, obtaining as a result the fabric object of the present method and invention.
Comprende, en la versión básica las siguientes fases, que pueden repetirse según se necesiten para la confección: In the basic version, it includes the following phases, which can be repeated as needed for manufacturing:
En una primera fase se dispone un primer hilo 11 con una primera pasada de interlock 1 , comenzando por delante o por detrás, dejando de manera alterna una aguja libre 23,24, tal y como se muestra en la Figura 1. Seguidamente, en la fase segunda, se dispone un segundo hilo 12 con una segunda pasada de interlock 2, ocupando las agujas libres 23,24 de la primera pasada de interlock 1. Al propio tiempo, también se dejan libres las agujas ocupadas 21,22 de la primera pasada de interlock 1, es decir, entre ambas pasadas se ocupan todas las agujas de manera alterna. Ello supone que el primer hilo 11 y el segundo hilo 12 quedan entre sí entrecruzados. In a first phase, a first thread 11 is arranged with a first interlock pass 1, starting in front or behind, alternately leaving a free needle 23, 24, as shown in Figure 1. Next, in the second phase, a second thread 12 is arranged with a second interlock pass 2, occupying the free needles 23,24 of the first interlock pass 1. At the same time, the occupied needles 21,22 of the first pass are also left free of interlock 1, that is, between the two passes all the needles are occupied alternately. This means that the first thread 11 and the second thread 12 intertwine with each other.
En esta realización el segundo hilo 12 cuando hace la segunda pasada de interlock 2 es en sentido contrario a la interlock de la primera pasada 1 , pero podrían hacerse las dos pasadas de interlock 1,2 a la vez en el mismo sentido, ya que dependerá del tipo de máquina si lo permite o no. El hecho de que estos hilos 11,12 de interlock queden entrecruzados entre sí, permite que el tejido alcance una gran resistencia, de tal manera que resulta muy difícil separarlos. En la tercera fase se dispone un tercer hilo 13 con una primera pasada de cordón desagujado 3 por delante o por detrás, dejando alternativamente una aguja libre 25. In this embodiment, when the second thread 12 makes the second pass of interlock 2, it is in the opposite direction to the interlock of the first pass 1, but the two passes of interlock 1,2 could be made at the same time in the same direction, since it will depend of the type of machine if it allows it or not. The fact that these interlock threads 11, 12 are intertwined with each other allows the fabric to achieve great resistance, in such a way that it is very difficult to separate them. In the third phase, a third thread 13 is arranged with a first pass of unneedled cord 3 in front or behind, alternately leaving a free needle 25.
Por último, en la cuarta fase se dispone un cuarto hilo 14 con una segunda pasada de cordón desagujado 4 bien por detrás si en la primera pasada de cordón desagujado 3 fue por delante, bien por delante si en la primera pasada de cordón desagujado 3 fue por detrás, en sentido contrario a la primera pasada de cordón desagujado 3, dejando alternativamente una aguja libre 26. De este modo, queda enfrentada una aguja libre 26 de la segunda pasada de cordón desagujado 4 con una aguja ocupada 27 de la primera pasada de cordón desagujado 3 y una aguja ocupada 28 de la segunda pasada de cordón desagujado 4 con una aguja libre 25 de la primera pasada de cordón desagujado 3. Esto permite que el punto quede muy cerrado, y que al presionar sobre uno de ellos, como unos se apoyan en otros, se cierren los espacios en ese punto y se impide tanto el corte como el pinchazo. Finally, in the fourth phase, a fourth thread 14 is arranged with a second pass of unneedled cord 4 either behind if in the first pass of unneedled cord 3 it was in front, or in front if in the first pass of unneedled cord 3 it was from behind, in the opposite direction to the first pass of unthreaded cord 3, alternately leaving a free needle 26. In this way, a free needle 26 of the second pass of unthreaded cord 4 is facing an occupied needle 27 of the first pass of unneedled cord 3 and a busy needle 28 from the second pass of unneedled cord 4 with a free needle 25 from the first pass of unneedled cord 3. This allows the stitch to be very closed, and when pressing on one of them, like some are supported by others, the spaces are closed at that point and both cutting and puncture are prevented.
Las pasadas de cordón desagujado 3,4 se pueden realizar antes de la primera pasada de interlock 1 o bien después de la segunda pasada de interlock 2, dependerá del tipo de prenda a confeccionar. The unneedled lace passes 3,4 can be made before the first pass of interlock 1 or after the second pass of interlock 2, depending on the type of garment to be made.
Los hilos empleados 11,12,13,14 son hilos de altas propiedades mecánicas. Se entienden hilos con altas propiedades mecánicas aquellos que ofrecen resistencia a la tracción, a la fractura, al desgarro, gran durabilidad, resistencia a la fatiga, resistencia al desgaste y a la punción entre otras. Se busca que los hilos tengan alta tenacidad y resistencia al corte para evitar la penetración del filo del cuchillo y elementos penetrantes como fragmentos de explosivos y perdigones de caza. The threads used 11,12,13,14 are threads with high mechanical properties. Threads with high mechanical properties are understood to be those that offer resistance to traction, fracture, tearing, great durability, resistance to fatigue, resistance to wear and puncture, among others. It is sought that the threads have high tenacity and resistance to cutting to avoid the penetration of the knife edge and penetrating elements such as explosive fragments and hunting pellets.
Los hilos empleados son de entre 50 y 1600 Deniers. Los Deniers hacen referencia a los Denier Total (aglomeración de filamentos). A menos deniers el hilo será más fino, más adaptable y transparente, a más deniers más opaco y más resistente. The threads used are between 50 and 1600 Deniers. Deniers refer to Total Denier (filament agglomeration). The less deniers the thread will be finer, more adaptable and transparent, the more deniers it will be more opaque and more resistant.
Unos ejemplos de hilos con altas propiedades mecánicas son un polietileno de ultra alta densidad o un poliporafenileno tereftalamida. Some examples of threads with high mechanical properties are an ultra-high-density polyethylene or a polyporaphenylene terephthalamide.
El método puede repetir las fases anteriores hasta completar el tejido o la prenda, o bien añadir las siguientes fases adicionales. Así, en una quinta fase se dispone un quinto hilo 15 con una tercera pasada de interlock 5, con igual esquema que en la primera pasada de interlock 1. The method can repeat the previous phases until the fabric or garment is complete, or add the following additional phases. Thus, in a fifth phase, a fifth thread 15 is arranged with a third interlock pass 5, with the same scheme as in the first interlock pass 1.
En una sexta fase, se dispone un sexto hilo 16 con una cuarta pasada de interlock 6 con el mismo esquema que la segunda pasada de interlock 2, y quedando el quinto hilo 15 y el sexto hilo 16 entrecruzados, que como en la fase segunda, esta configuración entrecruzada confiere una gran resistencia ante el intento de separar los hilos 15,16, por ejemplo, cuando se intenta penetrar los mismos con un objeto punzante como un cuchillo de cocina. En una séptima fase se dispone un séptimo hilo 17 con una tercera pasada de cordón desagujado 7 por el mismo lado que la primera pasada de cordón desagujado 3, dejando alternativamente una aguja libre, ocupando las agujas libres de la primera pasada de cordón desagujado 3 y dejando libres las agujas ocupadas de la primera pasada de cordón desagujado 3. In a sixth phase, a sixth thread 16 is arranged with a fourth interlock course 6 with the same scheme as the second interlock course 2, and leaving the fifth thread 15 and the sixth thread 16 intertwined, which as in the second phase, This interlocked configuration confers great resistance when trying to separate the threads 15,16, for example, when trying to penetrate them with a sharp object such as a kitchen knife. In a seventh phase, a seventh thread 17 is arranged with a third course of unneedled cord 7 on the same side as the first course of unneedled cord 3, alternately leaving a free needle, occupying the free needles of the first course of unneedled cord 3 and freeing the busy needles of the first pass of unneedled cord 3.
Por último, en la octava fase se dispone un octavo hilo 18 con una cuarta pasada de cordón desagujado 8 por el mismo lado que la segunda pasada de cordón desagujado 4, dejando alternativamente una aguja libre, ocupando las agujas libres de la segunda pasada de cordón desagujado 4 y dejando libres las agujas ocupadas de la segunda pasada de cordón desagujado 4. Si nos atenemos a lo mostrado en la figura 8, que es un simple esquema, que ayuda al entendimiento, el hilo pasaría a través de las agujas en el siguiente orden: Finally, in the eighth phase, an eighth thread 18 is arranged with a fourth course of unneedled cord 8 on the same side as the second course of cord. 4, alternately leaving a free needle, occupying the free needles of the second pass of unhooked cord 4 and leaving free the occupied needles of the second pass of unhooked cord 4. If we abide by what is shown in figure 8, which is a simple scheme, which helps to understand, the thread would pass through the needles in the following order:
- En la primera fase el hilo pasaría a través de las agujas en el orden A-D- A-D-A-D, - In the first phase the thread would pass through the needles in the order A-D-A-D-A-D,
- En la segunda fase el hilo pasaría a través de las agujas en el orden C-B- C-B-C-B, - In the second phase the thread would pass through the needles in the order C-B-C-B-C-B,
- En la tercera fase el hilo pasaría a través de las agujas en el orden A-A-- In the third phase the thread would pass through the needles in the order A-A-
A, A,
- En la cuarta fase el hilo pasaría a través de las agujas en el orden D-D-D,- In the fourth phase the thread would pass through the needles in the order D-D-D,
- En la quinta fase el hilo pasaría a través de las agujas en el orden A-D-A- D-A-D, - In the fifth phase the thread would pass through the needles in the order A-D-A-D-A-D,
