Description
Proceso para obtener una tela no tejida con zonas de permeabilidad.Process to obtain a non-woven fabric with zones of permeability.
Normalmente, para la cubierta u hoja superior de
artículos absorbentes desechables, tales como pañales desechables,
compresas femeninas y calzones entrenadores, se usan telas no
tejidas de diferentes composiciones. Con el fin de evitar
escurrimientos y proteger la ropa exterior del usuario, es
conveniente que la tela no tejida utilizada tenga zonas con
diferente permeabilidad, es decir, que tenga el centro hidrófilo
con el fin de que los desechos líquidos y semilíquidos penetren con
facilidad, y los extremos hidrófobos, con el fin de que los
desechos no lleguen hasta las orillas longitudinales de la prenda y
puedan manchar la ropa que está en contacto con el artículo
absorbente
desechable.Normally, for the cover or top sheet of disposable absorbent articles, such as disposable diapers, female pads and training pants, nonwoven fabrics of different compositions are used. In order to avoid runoff and protect the user's outer clothing, it is convenient that the nonwoven fabric used has areas with different permeability, that is, that it has the hydrophilic center so that liquid and semi-liquid wastes easily penetrate, and hydrophobic ends, so that the debris does not reach the longitudinal edges of the garment and can stain clothing that is in contact with the absorbent article
disposable.
En la actualidad existen en el mercado este tipo de telas, tratadas de tal forma que tienen zonas hidrófilas y zonas hidrófobas, tal como la descrita en la patente MX 191.385, en la que se divulga un artículo absorbente desechable tal como un pañal desechable, que comprende una hoja superior compuesta por tres zonas, una zona central permeable y zonas laterales impermeables. El artículo está provisto de barreras laterales dispuestas en las zonas laterales. Otras patentes que tratan sobre este tema son las patentes US 5.709.747, 5.885.656 y 6.183.847, todas de Avgol Nonwoven Industries, y que describen un método para transformar una tela hidrófoba en hidrófila, o viceversa, usando cubiertas ajustables en un rollo aplicador que gira en un baño de líquido, de modo que el líquido se coloca en áreas seleccionadas de la tela según ésta se mueve sobre el rollo, y cambie las propiedades hidrófobas o hidrófilas de la tela.At present there are in the market this type of fabrics, treated in such a way that they have hydrophilic zones and zones hydrophobic, such as that described in MX 191,385, in the that a disposable absorbent article such as a diaper is disclosed disposable, comprising a top sheet composed of three zones, a permeable central zone and impermeable lateral zones. The article is provided with side barriers arranged in the lateral areas Other patents dealing with this subject are the US patents 5,709,747, 5,885,656 and 6,183,847, all of Avgol Nonwoven Industries, and they describe a method to transform a Hydrophobic cloth in hydrophilic, or vice versa, using covers adjustable in an applicator roll that rotates in a liquid bath, of so that the liquid is placed in selected areas of the fabric as it moves over the roll, and change the properties hydrophobic or hydrophilic of the fabric.
La presente invención protege un método para zonificar una tela no tejida, que es tratada además con un líquido que la suaviza y la imparte propiedades antirrozaduras, tal como el descrito en la solicitud de patente mexicana 9810294, o bien con cualquier otro tipo de suavizante y/o protector para la piel, tal como aloe vera, de modo que la tela resultante, además de estar zonificada, tenga propiedades mejoradas para estar en contacto con la piel del usuario. El método consiste en atomizar un líquido que cambia la propiedad hidrófoba de la zona central de la tela en hidrófila y después rociar el líquido suavizante y protector sobre el ancho total de la tela, obteniendo un producto único zonificado y con propiedades antirrozaduras.The present invention protects a method for Zoning a non-woven fabric, which is also treated with a liquid which softens and imparts anti-scratch properties, such as the described in Mexican patent application 9810294, or with any other type of softener and / or skin protector, such as aloe vera, so that the resulting fabric, besides being zoned, have improved properties to be in contact with The skin of the user. The method is to atomize a liquid that the hydrophobic property of the central area of the fabric changes in hydrophilic and then spray the softening and protective liquid on the total width of the fabric, obtaining a unique zoned product and with anti-scratch properties.
Un objetivo de la invención es proporcionar un método sencillo y económico para obtener una tela con zonas hidrófilas e hidrófobas.An object of the invention is to provide a simple and economical method to obtain a fabric with zones hydrophilic and hydrophobic.
Otro objetivo de la invención es que este método sea sencillo y económico.Another object of the invention is that this method Be simple and economical.
Un objetivo adicional de la invención es que el método incluya la aplicación sobre la tela de un líquido suavizante, antirrozaduras, o que imparta a la tela alguna característica que ayude a mantener la piel del eventual usuario en buen estado.A further objective of the invention is that the method include the application on the cloth of a liquid softener, anti-scratch, or impart to the fabric any feature that helps keep the skin of the eventual user in good condition
Un objetivo más de la invención es que la tela obtenida, además de zonas hidrófilas e hidrófobas, sea suave y tenga propiedades antirrozaduras.A further objective of the invention is that the fabric obtained, in addition to hydrophilic and hydrophobic areas, be gentle and have anti-scratch properties.
- La figura 1, muestra un atomizador para rociar el líquido zonificador, encargado de cambiar las propiedades hidrófobas de la tela.- Figure 1 shows an atomizer to spray the zoning liquid, responsible for changing the properties hydrophobic fabric.
- La figura 2, es un diagrama del proceso de fabricación de tela no tejida con zonas hidrófobas e hidrófilas y con propiedades antirrozaduras.- Figure 2, is a diagram of the process of manufacture of nonwoven fabric with hydrophobic and hydrophilic areas and with anti-scratch properties.
- La figura 3, ilustra el atomizador que rocía el líquido suavizante y antirrozaduras sobre la tela.- Figure 3 illustrates the atomizer that sprays the Smoothing liquid and anti-scratch on the fabric.
- La figura 4 muestra la tela no tejida resultante.- Figure 4 shows the non-woven fabric resulting.
En general, la mayoría de los artículos
absorbentes desechables utilizan tela no tejida como capa superior,
tela no tejida que, dependiendo de su composición y gramaje, tiene
diferentes propiedades. En el mercado, se pueden encontrar telas
100% de polipropileno, mezclas de polipropileno y poliéster,
polietileno,
rayón, etc.In general, most disposable absorbent articles use nonwoven fabric as a top layer, nonwoven fabric which, depending on its composition and weight, has different properties. On the market, you can find 100% polypropylene fabrics, polypropylene and polyester blends, polyethylene,
rayon, etc.
El uso de tela 100% de polipropileno o mezclada
con un porcentaje mínimo de poliéster, es adecuado para la capa
superior de pañales desechables y compresas femeninas. Sin embargo,
este tipo de telas son hidrófobas por su propia naturaleza al salir
de producción y, si bien el líquido puede eventualmente
penetrarlas, no lo hace rápidamente, ocasionando que el líquido
quede durante algún tiempo en contacto con la piel y pueda causar
daño a la misma. Por lo anterior, es conveniente tratar la zona
central de una tela no tejida, que es originalmente hidrófoba, con
algún líquido que la tome hidrófila, de tal modo que el producto
resultante tenga los extremos hidrófobos para evitar escurrimientos
y el centro hidrófilo para que los exudados líquidos o semilíquidos
penetren con facilidad. Este tipo de productos existen en el
mercado; sin embargo, tienen el inconveniente de que después de las
primeras descargas, el líquido es arrastrado y la tela nuevamente
es 100% hidrófoba. Por otro lado, en el método de la presente
invención, se añade también la aplicación sobre la tela no tejida
de un líquido antirrozaduras, de modo que el producto resultante
sea una tela no tejida con una zona central hidrófila, dos zonas
laterales hidrófobas y con propiedades
antirrozaduras.The use of 100% polypropylene fabric or mixed with a minimum percentage of polyester, is suitable for the top layer of disposable diapers and female pads. However, these types of fabrics are hydrophobic by their very nature when they leave production and, although the liquid may eventually penetrate them, it does not do so quickly, causing the liquid to remain in contact with the skin for some time and may cause damage to the same. Therefore, it is convenient to treat the central area of a non-woven fabric, which is originally hydrophobic, with some liquid that takes it hydrophilic, so that the resulting product has hydrophobic ends to prevent runoff and the hydrophilic center so that the liquid or semi-liquid exudates penetrate easily. These types of products exist in the market; however, they have the disadvantage that after the first discharges, the liquid is entrained and the fabric is 100% hydrophobic again. On the other hand, in the method of the present invention, the application on the non-woven fabric of an anti-scratch liquid is also added, so that the resulting product is a non-woven fabric with a hydrophilic central zone, two hydrophobic side zones and with properties
anti-scratches
Para efectos explicativos, al líquido que cambia la propiedad hidrófoba de la tela no tejida en hidrófila, se le llamará líquido zonificador (10). Este líquido contiene lubricantes no iónicos, agentes antiestáticos y agentes hidrófilos, de modo que esta propiedad persista después de descargas múltiples. El líquido se dispersa en agua por lo que puede ser aplicado directamente o en diluciones hasta de alrededor del 50%. Para que funcione adecuadamente, debe aplicarse en una proporción mínima del 0,25% del peso base de la tela, independientemente de la dilución a la cual se aplique. Por ejemplo, si la tela tiene un peso base de 20 g/m^{2}, la cantidad mínima de líquido a aplicar debe ser de 0,05 gr/m^{2}. Así, si la dilución es al 25% deben aplicarse 0,2 g/m^{2} de líquido diluido para lograr la aplicación deseada.For explanatory purposes, to the liquid that changes The hydrophobic property of the nonwoven fabric in hydrophilic, is will call zoning liquid (10). This liquid contains lubricants non-ionic, antistatic agents and hydrophilic agents, so that This property persists after multiple downloads. The liquid it disperses in water so it can be applied directly or in dilutions up to about 50%. To make it work properly, it should be applied in a minimum proportion of 0.25% of the base weight of the fabric, regardless of the dilution at which apply For example, if the fabric has a basis weight of 20 g / m2, the minimum amount of liquid to be applied must be 0.05 gr / m2. Thus, if the dilution is 25% 0.2 should be applied g / m2 of diluted liquid to achieve the desired application.
La figura 1 muestra la forma de aplicación mediante rociado y únicamente en la zona central de la tela. Se puede ver la válvula atomizadora (4) y la tela no tejida (1) resultante con la zona central hidrófila (2) y las zonas laterales (3) hidrófobas.Figure 1 shows the form of application by spraying and only in the central area of the fabric. I know You can see the atomizing valve (4) and the non-woven fabric (1) resulting with the hydrophilic central zone (2) and the lateral zones (3) hydrophobic.
Inmediatamente después de la aplicación del líquido zonificador (10), se aplica el líquido antirrozaduras, como se puede ver en la figura 2, que muestra el proceso de fabricación de una tela con zonas hidrófobas e hidrófilas y con propiedades antirrozaduras. En la figura 2 se ilustra un proceso de fabricación de tela no tejida mediante cardado y unión térmica, pero ambos líquidos funcionan independientemente del método de fabricación de la tela no tejida. De acuerdo con la figura 2, una vez que la tela no tejida es cardada (6) y unida mediante unión térmica (7), se aplica mediante rociado (4) y en la zona central de la tela, el líquido zonificador (10) para inmediatamente después aplicar el líquido antirrozaduras (11) en todo el ancho de la tela no tejida también mediante rociado (5). Después de esta operación la tela se corta (8) y se enrolla (9).Immediately after the application of zoning liquid (10), the anti-scratch liquid is applied, such as It can be seen in Figure 2, which shows the manufacturing process of a fabric with hydrophobic and hydrophilic areas and with properties anti-scratches A manufacturing process is illustrated in Figure 2 of non-woven fabric by carding and thermal bonding, but both liquids work independently of the manufacturing method of The non-woven fabric. According to figure 2, once the fabric Nonwoven is carded (6) and joined by thermal bonding (7), it applied by spraying (4) and in the central area of the fabric, the zoning liquid (10) to immediately after applying the anti-scratch liquid (11) across the entire width of the nonwoven fabric also by spraying (5). After this operation the fabric will cut (8) and roll up (9).
El líquido antirrozaduras (11) se aplica, como se
muestra en la figura 3, a todo lo ancho de la tela una vez que ésta
ya ha sido zonificada. Sin embargo, el proceso puede invertirse
aplicando primero el líquido antirrozaduras (11) para aplicar
después el líquido zonificador (10). El líquido antirrozaduras es
una composición formada de alcoholes aromáticos y sus derivados no
fenólicos, sales y sus derivados del ácido cítrico, derivados
alcohólicos de ácidos grasos superiores y ésteres de ácidos
triglicéridos y sus derivados. Los alcoholes aromáticos y sus
derivados no fenólicos así como las sales y sus derivados del ácido
cítrico, actúan como agentes bacteriostáticos que detienen la acción
de los microorganismos que se nutren de urea y generan amoníaco,
mientras que los ácidos triglicéridos y sus derivados lubrican las
células de la piel proporcionando una barrera contra los agentes
irritantes y permitiendo la respiración de la piel, suavizando
además las fibras textiles. Los derivados alcohólicos de ácidos
grasos superiores inhiben la formación de antígenos que inducen las
alergias. De este modo el líquido antirrozaduras (11) crea una capa
protectora en la tela no tejida proporcionándole características
importantes para el cuidado de la piel. Por otro lado, este líquido
antirrozaduras (11) puede estar adicionado con aloe vera y vitamina
E para proporcionar una tela con un tratamiento completo para la
piel del
usuario.The anti-scratch liquid (11) is applied, as shown in Figure 3, to the entire width of the fabric once it has already been zoned. However, the process can be reversed by first applying the anti-scratch liquid (11) to then apply the zoning liquid (10). The anti-scratch liquid is a composition formed of aromatic alcohols and their non-phenolic derivatives, salts and their citric acid derivatives, alcoholic derivatives of higher fatty acids and esters of triglyceride acids and their derivatives. Aromatic alcohols and their non-phenolic derivatives, as well as salts and their citric acid derivatives, act as bacteriostatic agents that stop the action of microorganisms that feed on urea and generate ammonia, while triglyceride acids and their derivatives lubricate cells of the skin providing a barrier against irritating agents and allowing the skin to breathe, also softening textile fibers. Alcoholic derivatives of higher fatty acids inhibit the formation of antigens that induce allergies. In this way the anti-scratch liquid (11) creates a protective layer on the non-woven fabric providing important characteristics for skin care. On the other hand, this anti-scratch liquid (11) can be added with aloe vera and vitamin E to provide a fabric with a complete treatment for the skin of the
user.
Es importante hacer notar que este líquido antirrozaduras (11) es insoluble en agua, por lo que puede ser aplicado antes o después del líquido zonificador (10) sin mezclarse con éste ni alterar sus propiedades.It is important to note that this liquid Anti-scratch (11) is insoluble in water, so it can be applied before or after the zoning liquid (10) without mixing with it or alter its properties.
Así las cosas, mediante este método, se obtiene una tela no tejida (1), tal como la mostrada en la figura 4, con una zona central hidrófila (2), dos zonas laterales hidrófobas (3) y con propiedades antirrozaduras, suavizantes y de cuidado de la piel.So things, through this method, you get a non-woven fabric (1), such as that shown in Figure 4, with a hydrophilic central zone (2), two hydrophobic lateral zones (3) and with anti-scratch, softening and care properties of the skin.
Si bien la invención ha sido descrita en función de sus modalidades preferidas, su alcance comprende cualquier tipo de cambio o modificación que pueda ser evidente para un técnico en la materia.While the invention has been described in function of its preferred modalities, its scope includes any type of change or modification that may be evident to a technician in The matter.
