Procedimiento de obtención de un tejido y tejido obtenido Procedure for obtaining a tissue and tissue obtained
Sector de la técnicaTechnical sector
La presente invención se refiere a un procedimiento de obtención de un tejido que presenta la especial particularidad de que sus caras externas e internas presentan características distintas, de modo que su cara interna es completamente hidrófila, mientras que su cara externa es completamente repelente de líquidos. The present invention refers to a procedure for obtaining a fabric that has the special peculiarity that its external and internal faces have different characteristics, so that its internal face is completely hydrophilic, while its external face is completely liquid repellent.
Se trata pues de ofrecer un tejido sumamente versátil, en virtud de ofrecer prestaciones adicionales a las anteriormente descritas, como son la elasticidad, anti-arrugas, antibacteriano, secado rápido, etc. It is therefore about offering a highly versatile fabric, by virtue of offering additional features to those previously described, such as elasticity, anti-wrinkle, antibacterial, quick drying, etc.
Antecedentes de la invenciónBackground of the invention
En el ámbito de aplicación práctica de la invención se conocen procesos para la obtención de tejidos de características hidrófilas, así como procesos para la obtención de tejidos con propiedades repelentes de líquidos. In the scope of practical application of the invention, processes are known for obtaining fabrics with hydrophilic characteristics, as well as processes for obtaining fabrics with liquid-repellent properties.
Sin embargo, no se conoce la existencia de un tejido que aúne ambas propiedades. However, the existence of a fabric that combines both properties is not known.
En el mejor de los casos, se conoce un proceso en el que se obtiene un tejido multi-capa, en el que participa una capa externa de un tejido repelente a líquidos y una capa interna de un tejido hidrófilo, de manera que dichos dos tejidos se cosen entre si formando una estructura multi-capa. In the best of cases, a process is known in which a multi-layer fabric is obtained, in which an external layer of a liquid-repellent fabric and an internal layer of a hydrophilic fabric participate, so that said two fabrics They are sewn together forming a multi-layer structure.
Tejidos de este tipo de describen en las patentes de invención P200401889, P200931288, P201031360 Y WO11080368. Fabrics of this type are described in invention patents P200401889, P200931288, P201031360 and WO11080368.
Obviamente, esto supone un tejido sumamente grueso, que no resulta suficientemente cómodo, costoso por la gran cantidad de material que se utiliza en el mismo, y demasiado caluroso. Obviously, this means an extremely thick fabric, which is not comfortable enough, expensive due to the large amount of material used in it, and too hot.
En definitiva, la presente invención trata de simplificar el proceso para la obtención de un tejido con múltiples propiedades tale como la oleofobia, hidrofilia, elasticidad, anti-arrugas, anti bacteriano, secado rápido, duradera y anti-manchas y todo ello mediante un nuevo proceso más económico. In short, the present invention tries to simplify the process for obtaining a fabric with multiple properties such as oleophobia, hydrophilicity, elasticity, anti-wrinkle, anti-bacterial, quick-drying, durable and anti-stain, and all this through a new more economical process.
Explicación de la invenciónExplanation of the invention
El procedimiento de la invención viene a llenar el vacío técnico anteriormente descrito, permitiendo obtener un tejido mono-capa con propiedades distintas en su cara interior y exterior, concretamente con propiedades hidrófilas en su cara interior y repelente a líquidos por su cara externa, además de una serie de prestaciones adicionales. The method of the invention fills the technical gap described above, allowing a single-layer fabric to be obtained with different properties on its inner and outer face, specifically with hydrophilic properties on its inner face and liquid repellent on its outer face, in addition to a series of additional features.
Por ello, y de forma mas concreta, se parte de un hilo a base de poliéster 100% reciclado, multifilamento y anti-bacteriano, gracias a la incorporación de iones de plata, material que ofrece adicionalmente propiedades antivirales. For this reason, and more specifically, it is based on a thread based on 100% recycled polyester, multifilament and antibacterial, thanks to the incorporation of silver ions, a material that additionally offers antiviral properties.
El hilo presentará una sección con múltiples canales a lo largo de su sección longitudinal. Esta forma de sección genera unos surcos en la superficie que ayudan a la gestión de la humedad y facilitan que el tejido se seque rápidamente. The thread will have a section with multiple channels along its longitudinal section. This shape of section generates grooves on the surface that help with moisture management and make it easier for the fabric to dry quickly.
A partir de este hilo se procede a llevar a cabo el proceso de tejeduría, construyendo un tejido de punto circular de doble cara: una cara exterior mas "lisa” , y una cara interior con una trama tridimensional tipo "piqué”. From this thread the weaving process is carried out, constructing a double-sided circular knitted fabric: a "smooth" outer face, and an inner face with a three-dimensional "piqué" type weave.
De este modo, se consigue que el tejido sea elástico y transpirable. In this way, the fabric is made elastic and breathable.
Por último, el tejido se somete a un proceso de termofijación a un ancho y temperaturas concretas, dándole así la propiedad de "anti-arrugas”. Finally, the fabric is subjected to a thermosetting process at a specific width and temperature, thus giving it the "anti-wrinkle" property.
Tras la obtención del tejido, este se somete a una fase de lavado o descrudado, teñido y seguidamente se somete a un proceso de bañado en un producto "hidrófilo” , con el que se consigue que el tejido sea muy absorbente a la humedad. After obtaining the fabric, it is subjected to a washing or scouring phase, dyed and then subjected to a bathing process in a "hydrophilic" product, which makes the fabric highly absorbent to moisture.
A continuación, el tejido se somete a un proceso de aplicación de un producto anti-manchas, el cual, en vez de aplicarse por bañado, se lleva a cabo mediante aplicación por rodillo, lo que permite aplicar dicho producto únicamente por una de las dos caras del tejido. Next, the fabric is subjected to a process of applying an anti-stain product, which, instead of being applied by dipping, is carried out by roller application, which allows said product to be applied only on one of the two sides. faces of the fabric.
Por último, este acabado se termofija a una temperatura y durante una duración determinadas para conseguir que el producto permanezca durante mucho tiempo en el tejido a pesar de los lavados o el uso. Finally, this finish is heat-set at a certain temperature and for a certain duration to ensure that the product remains on the fabric for a long time despite washing or use.
Finalmente, con el tejido obtenido se confeccionan las correspondientes prendas, que presentan todas estas características: Finally, with the fabric obtained, the corresponding garments are made, which have all these characteristics:
• Internamente hidrófilo • Internally hydrophilic
• Externamente anti-manchas. • Externally anti-stain.
• Antibcateriano. • Antibacterial.
• Antivírico. • Antiviral.
• Elástico. • Elastic.
• Anti-arrugas. • Anti-wrinkle.
• Transpirable. • Breathable.
• Secado rápido. • Fast dry.
• Reciclado. • Recycled.
Descripción de los dibujosDescription of the drawings
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor compresión de las características del invento, de acuerdo con un ejemplo preferente de realización practica del mismo, se acompaña como parte integrante de dicha descripción, un plano en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente: To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, in accordance with a preferred example of its practical implementation, a plan is attached as an integral part of said description, where For illustrative and non-limiting purposes, the following has been represented:
La figura 1. - Muestra un diagrama de bloques de las diferentes fases operativas necesarias para obtener un tejido mono-capa con propiedades distintas en sus dos caras, realizado de acuerdo con el objeto de la presente invención. Figure 1. - Shows a block diagram of the different operational phases necessary to obtain a single-layer fabric with different properties on its two sides, made in accordance with the object of the present invention.
Realización preferente de la invenciónPreferred embodiment of the invention
A la vista de la figura reseñada, puede observarse como el proceso de la invención se parte de un material (1) inicial, concretamente hilos de poliéster 100% reciclado, en el que el hilo presenta una estructura multifilamento, es decir, en lugar de un único hilo grueso, hay 47 micro-hilos muy finos. In view of the figure outlined, it can be seen how the process of the invention starts from an initial material (1), specifically 100% recycled polyester threads, in which the thread has a multifilament structure, that is, instead of a single thick thread, there are 47 very fine micro-threads.
Esto ayuda a que exista "aire” entre ellos y generen una barrera térmica. Además, el hecho de que sean tan finos hace que el tejido sea muy suave. This helps to create "air" between them and generate a thermal barrier. In addition, the fact that they are so thin makes the fabric very soft.
Estos hilos incluyen iones de plata, presentes en toda materia, tanto en el interior como en el exterior de los hilos. De este modo se consigue un efecto anti-bacteriano que permanece a pesar de los lavados o el paso del tiempo. Este tratamiento a su vez demostró que presenta actividad antiviral (en 2 horas se eliminan el 95% de coronavirus). These threads include silver ions, present in all matter, both inside and outside the threads. In this way, an antibacterial effect is achieved that remains despite washing or the passage of time. This treatment in turn demonstrated that it has antiviral activity (95% of coronavirus is eliminated in 2 hours).
Otra de las características del hilo es su sección con múltiples canales a lo largo de su sección longitudinal. Esta forma de sección genera unos surcos en la superficie que ayudan a la gestión de humedad y facilitan que el tejido se seque rápidamente. Another characteristic of the thread is its section with multiple channels along its longitudinal section. This shape of section generates grooves on the surface that help with moisture management and make it easier for the fabric to dry quickly.
A partir de este material, se procede a la fase de tejeduría (2), construyendo un tejido de punto circular de doble cara: una cara exterior más "lisa” , y una cara interior con una trama tridimensional tipo "piqué”. From this material, we proceed to the weaving phase (2), constructing a double-sided circular knitted fabric: a "smooth" outer face, and an inner face with a three-dimensional "piqué" type weave.
De este modo se consigue que el tejido sea "elástico” (al ser un tejido de punto circular y no un tejido de calada), y que la cara interior mejore la "transpirabilidad” (gracias a esta estructura tridimensional y a los canales que se forman). In this way, the fabric is made "elastic" (as it is a circular knitted fabric and not a openwork fabric), and the inner side improves "breathability" (thanks to this three-dimensional structure and the channels that are formed). ).
Seguidamente se procede a someter el tejido a un primer proceso de termofijación (2) a un ancho concreto y a una temperatura de 150° C durante 1 minuto y 10 segundos, y gracias al tipo de materia empleado (poliéster) y de su estructura textil, se consigue que el tejido no presente arrugas. En tal sentido se pueden utilizar fibras de poliuretano reticulable suave y flexible que presentan unas características optimas para la obtención de tejidos con propiedades anti arrugas. The fabric is then subjected to a first heat-fixing process (2) at a specific width and at a temperature of 150° C for 1 minute and 10 seconds, and thanks to the type of material used (polyester) and its textile structure, This ensures that the fabric does not present wrinkles. In this sense, soft and flexible cross-linkable polyurethane fibers can be used that have optimal characteristics for obtaining fabrics with anti-wrinkle properties.
Una vez el tejido está fabricado, se somete a un proceso de lavado (4) (se descuadra), un proceso de teñido (5) y un proceso de aplicación de un baño (6) (inmersión-fulard) de un producto "hidrófilo” , producto que a modo meramente ejemplario, se aplica a una presión de 3 bares con una velocidad de avance del tejido de 15 metros por minuto. Once the fabric is manufactured, it is subjected to a washing process (4) (it is unbalanced), a dyeing process (5) and a process of applying a bath (6) (immersion-fulard) of a "hydrophilic" product. ", a product that, as an example, is applied at a pressure of 3 bars with a fabric advance speed of 15 meters per minute.
En el proceso de lavado se aplica poliuretano alifático en solución acuosa que proporciona un tacto suave y elástico con un excelente comportamiento a tratamientos húmedos. De igual manera se podrá aplicar un producto anti-olor. In the washing process, aliphatic polyurethane is applied in an aqueous solution, which provides a soft and elastic touch with excellent behavior in wet treatments. In the same way, an anti-odor product can be applied.
En cuanto al proceso de baño (inmersión-fulard), se aplicará preferentemente un polímero hidrófilo especial con alta afinidad a la fibra PES. Regarding the bath process (immersion-fulard), a special hydrophilic polymer with high affinity will preferably be applied to the PES fiber.
De este modo, se consigue que el tejido sea muy absorbente a la humedad. In this way, the fabric is very moisture-absorbent.
En una fase posterior se aplica mediante rodillo (7) un producto antimanchas, esta vez no por baño (inmersión-fulard) que deposita el producto antimanchas sobre unas de las caras del tejido, la que será finalmente la cara exterior del mismo. In a later phase, an anti-stain product is applied using a roller (7), this time not by bath (immersion-fulard) that deposits the anti-stain product on one of the faces of the fabric, which will ultimately be its outer face.
Este producto antimanchas es la unión de 3 complementos: un producto repelente de manchas oléofobo e hidrófobo, otro producto que fija este producto antimanchas al tejido un isocianato, y, por último, un producto espesante que hace que la mezcla de los 3 productos presente una viscosidad adecuada para que se pueda extender bien por el tejido, pero que impida que el producto penetre a la cara interior del mismo. This anti-stain product is the union of 3 complements: an oleophobic and hydrophobic stain repellent product, another product that fixes this anti-stain product to the fabric, an isocyanate, and, finally, a thickening product that makes the mixture of the 3 products present a Adequate viscosity so that it can spread well through the fabric, but prevents the product from penetrating the inside of the fabric.
De forma más concreta, el producto hidrófobo, se materializará en producto hidrofugante basado en fluorocarbono o perfluoracrilato no iónico para fibras sintéticas, naturales y sus mezclas. Se empleará un isocianato bloqueado para el ejemplo conjunto con resinas de fluorocarbono que confiere resistencia a los lavados, y un espesante en emulsión inversa. More specifically, the hydrophobic product will take the form of a water-repellent product based on fluorocarbon or non-ionic perfluoracrylate for synthetic and natural fibers and their mixtures. A blocked isocyanate will be used for the example together with fluorocarbon resins that provide resistance to washing, and a thickener in inverse emulsion.
De forma mas concreta, el isocianato participará en una proporción de 20 g/l, el fluorocarbono en una proporción de 200 g/l y el espesante en una proporción de 10 g/l. More specifically, the isocyanate will participate in a proportion of 20 g/l, the fluorocarbon in a proportion of 200 g/l and the thickener in a proportion of 10 g/l.
Este proceso, unido a la mejora de absorción de humedad (hidrofilia) del paso anterior, es el que consigue que el tejido presente propiedades por ambas caras. This process, together with the improvement in moisture absorption (hydrophilicity) from the previous step, is what ensures that the fabric has properties on both sides.
Finalmente, el tejido se somete a una segunda fase de termofijado (8) auna temperatura de 150°C durante un minuto para conseguir que el producto permanezca durante mucho tiempo en el tejido sin pesar de los lavados o el uso. Finally, the fabric is subjected to a second heat setting phase (8) at a temperature of 150°C for one minute to ensure that the product remains on the fabric for a long time without despite washing or use.
A partir de este proceso se obtiene un tejido a base de poliéster 100% reciclado, en el que participa un hilo multifilamento con iones de plata a base de 47 micro-hilos, sección con múltiples canales a lo largo de su sección longitudinal, con una cara exterior lisa y una cara interior con una trama tridimensional, en el que esta embebido un producto hidrófilo, y que en su cara externa incorpora un recubrimiento a base de producto anti-manchas. From this process, a fabric based on 100% recycled polyester is obtained, in which a multifilament thread with silver ions based on 47 micro-threads participates, a section with multiple channels along its longitudinal section, with a smooth outer face and an inner face with a three-dimensional pattern, in which a hydrophilic product is embedded, and which on its outer face incorporates a coating based on an anti-stain product.
