Abstract

La zone revêtue de la couche de silicone (2) présente une pluralité de micros perforations (3).The zone coated with the silicone layer (2) has a plurality of micro perforations (3).

Description

L'invention concerne un complexe textile présentant sur au moins l'une de ses faces au moins une zone revêtue d'une couche de silicone. L'invention trouve une application avantageuse qui ne saurait toutefois être considérée comme limitative, dans le cas de produits de contention tels que les bas ou chaussettes, sans pour cela exclure d'autres articles dans le domaine textile notamment vestimentaire avec ou non des capacités de contention.The invention relates to a textile complex having on at least one of its faces at least one zone coated with a silicone layer. The invention finds an advantageous application which however can not be considered as limiting, in the case of compression products such as stockings or socks, without thereby excluding other articles in the textile field including clothing with or without capacity of contention.

Il est parfaitement connu pour un homme du métier d'équiper par exemple la partie supérieure des bas ou des chaussettes, d'une bande qui adhère par élasticité à la peau. On a, par ailleurs, proposé de traiter ces bandes de manière à éviter tout phénomène de glissement. Par exemple, le brevet FR 1 540 295 divulgue des bas ou chaussettes comportant une bande élastique de fixation revêtue d'un élastomère de silicone afin d'utiliser les caractéristiques antiglisses de ce produit, sans pour autant nuire à la fonction d'élasticité de la bande en considérant le caractère extensible du silicone.It is well known for a person skilled in the art to equip, for example, the upper part of socks or socks with a band that adheres elastically to the skin. It has, moreover, been proposed to treat these strips so as to avoid any sliding phenomenon. For example, patent FR 1 540 295 discloses stockings or socks comprising an elastic fastening strip coated with a silicone elastomer in order to use the anti-slip characteristics of this product, without impairing the elasticity function of the product. band considering the extensible nature of the silicone.

A partir de ce concept de base des perfectionnements ont été apportés notamment au niveau des caractéristiques du silicone afin d'améliorer son pouvoir tackant et d'éviter tout phénomène d'allergie tout en améliorant le confort. On peut citer par exemple l'enseignement du brevet FR 2 930 708. Ce brevet décrit une bande de fixation d'un article textile présentant une enduction de silicone ayant des caractéristiques d'adhésivité immédiates, de viscoélasticité avec un taux de transmission de vapeur d'eau et une biocompatibilité.From this basic concept, improvements have been made in particular in terms of the characteristics of the silicone in order to improve its tackiness and to avoid allergy phenomena while improving comfort. For example, the teaching of patent FR 2 930 708. This patent describes a fastening strip for a textile article having a silicone coating having immediate adhesive properties, viscoelasticity with a vapor transmission rate of water and biocompatibility.

Les résultats obtenus donnent satisfaction. Toutefois, des phénomènes de macération peuvent apparaitre en considérant la force de tension exercée par l'élasticité de la bande en vue d'assurer la fixation de l'article textile considéré. Ce phénomène de macération est susceptible d'apparaître notamment au niveau de la zone enduite de silicone pour obtenir l'effet antiglisse. En effet, si la bande de fixation peut présenter une structure textile suffisamment aérée, ce n'est pas le cas de la zone siliconée. Le taux de transmission de sueur n'est pas suffisant pour laisser échapper la transpiration. Pour tenter de remédier à cet inconvénient et obtenir une évacuation suffisante de la sueur, on a proposé dans la cas d'un support avec une zone siliconée, de soumettre la zone siliconée à un effet de soufflage pour obtenir, de manière concomitante, des ouvertures correspondantes sensiblement à celles que présentent le support textile constitué par une bande. Cette solution n'est pas satisfaisante car, outre le fait qu'elle nécessite un procédé de mise en oeuvre relativement complexe, la formation des ouvertures au niveau de la zone siliconée limite d'une manière significative le caractère antiglisse. L'invention s'est fixée pour but de remédier à ces inconvénients de manière simple, sûre, efficace et rationnelle. Le problème que se propose de résoudre l'invention est d'obtenir une aération suffisante y compris au niveau de la zone enduite de silicone afin de permettre une évacuation de la sueur, sans pour autant, nuire aux qualités de la zone siliconée notamment pour la fonction de maintien et d'antiglisse. Pour résoudre un tel problème il a été conçu et mis au point un complexe textile présentant sur au moins l'une de ses faces au moins une zone revêtue d'une couche de silicone, la zone revêtue de la couche de silicone présente une pluralité de micros perforations. Selon une autre caractéristique importante et pour résoudre le problème posé de réaliser en continu les micros perforations tenant en compte des éventuelles caractéristiques d'allongement du complexe textile, la zone revêtue de la couche de silicone reçoit un film protecteur, les micros perforations étant réalisées à la fois dans l'épaisseur dudit film et de ladite zone.The results obtained are satisfactory. However, maceration phenomena can occur by considering the tensile force exerted by the elasticity of the band to ensure the attachment of the textile article considered. This phenomenon of maceration is likely to appear in particular in the zone coated with silicone to obtain the anti-slip effect. Indeed, if the fastening strip may have a sufficiently ventilated textile structure, this is not the case of the silicone zone. The rate of sweat transmission is not enough to let perspiration escape. In an attempt to remedy this drawback and obtain sufficient evacuation of sweat, it has been proposed in the case of a support with a silicone zone, to subject the silicone zone to a blowing effect so as to concomitantly obtain openings. substantially corresponding to those presented by the textile support constituted by a band. This solution is not satisfactory because, besides the fact that it requires a relatively complex implementation process, the formation of the openings at the silicone zone significantly limits the anti-slip nature. The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner. The problem to be solved by the invention is to obtain sufficient aeration including at the level of the silicone-coated zone in order to allow evacuation of the sweat, without, however, adversely affecting the qualities of the silicone zone, especially for the Hold and anti-slip function. To solve such a problem it has been designed and developed a textile complex having on at least one of its faces at least one zone coated with a silicone layer, the zone coated with the silicone layer has a plurality of microphones perforations. According to another important characteristic, and to solve the problem of continuously producing the microperforations taking into account any elongation characteristics of the textile complex, the zone coated with the silicone layer receives a protective film, the microporous perforations being made at both in the thickness of said film and said area.

Dans ce cas, le complexe textile présente des capacités d'allongement pour être étirable, le film protecteur étant non étirable pour assurer un blocage mécanique au niveau de la zone revêtue de la couche silicone.In this case, the textile complex has elongation capabilities to be stretchable, the protective film being non-stretchable to provide a mechanical lock at the area coated with the silicone layer.

Selon une autre caractéristique, les micros perforations sont réalisées en continu à partir d'un poste fixe équipé d'une pluralité d'aiguilles, le complexe étant déplacé linéairement en continu par rapport audit poste. A noter que les micros perforations peuvent être réalisées immédiatement après la mise en place du film protecteur sur la zone siliconée ou bien dans une autre étape de fabrication.According to another characteristic, the microphones perforations are made continuously from a fixed station equipped with a plurality of needles, the complex being moved linearly continuously with respect to said station. Note that the micro perforations can be made immediately after the introduction of the protective film on the silicone zone or in another manufacturing step.

Dans une forme de réalisation, le complexe textile se présente sous la forme d'une bande aérée obtenue par tissage ou tricotage, la couche de silicone étant appliquée par un procédé d'enduction.In one embodiment, the textile complex is in the form of an aerated web obtained by weaving or knitting, the silicone layer being applied by a coating process.

Selon les caractéristiques de l'invention, de nombreuses applications du support textiles peuvent être envisagées. Dans une application avantageuse, la bande constitue la partie supérieure d'un bas ou d'une chaussette. La couche de silicone présente des caractéristiques aptes à permettre le maintien dudit support sur la peau d'une personne. L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels : la figure 1 est une coupe à caractère schématique du complexe textile selon l'invention, la figure 2 est une vue partielle en coupe et à très grande échelle du complexe textile montrant les micros perforations réalisées au niveau du film protecteur et de la zone siliconée, la figure 3 est une vue à caractère schématique montrant une forme de réalisation du procédé par la réalisation de micros perforations, la figure 4 montre un exemple de réalisation du support textile sous forme d'une bande de fixation apte à constituer la partie supérieure d'un bas ou d'une chaussette, la zone siliconée étant revêtue du film protecteur, la figure 5 est une vue correspondant à la figure 4 après enlèvement du film protecteur au niveau de la zone siliconée et micro perforée.According to the features of the invention, many applications of textile support can be envisaged. In an advantageous application, the band constitutes the upper part of a stocking or sock. The silicone layer has characteristics capable of allowing the support to be maintained on the skin of a person. The invention is described below in more detail with the aid of the figures of the accompanying drawings in which: FIG. 1 is a schematic section of the textile complex according to the invention, FIG. 2 is a partial view in section and on a very large scale of the textile complex showing the micro perforations made at the level of the protective film and the silicone zone, FIG. 3 is a schematic view showing one embodiment of the method by producing micro-perforations, FIG. an embodiment of the textile support in the form of a fastening strip capable of constituting the upper part of a stocking or sock, the silicone area being coated with the protective film, FIG. 5 is a view corresponding to FIG. 4 after removal of the protective film at the silicone zone and micro perforated.

L'invention s'applique à tout type de complexe ou support textile (1) obtenu par tissage ou tricotage. L'invention trouve une application avantageuse dans le cas d'un complexe textile (1) présentant des capacités d'allongement pour être étiré.The invention applies to any type of complex or textile support (1) obtained by weaving or knitting. The invention finds an advantageous application in the case of a textile complex (1) having elongation capabilities to be stretched.

Ce type de complexe est parfaitement connu pour un homme du métier et peut être obtenu par tout moyen connu et approprié en mettant en oeuvre notamment, en chaîne, tout type de fils élastiques. Le complexe textile (1) peut être tissé ou tricoté pour présenter une structure aérée en fonction des applications envisagées.This type of complex is well known to a person skilled in the art and can be obtained by any known and appropriate means by implementing in particular, in the chain, any type of elastic son. The textile complex (1) can be woven or knitted to have a ventilated structure depending on the intended applications.

Le complexe textile (1) qui peut se présenter, par exemple, sous forme d'une bande, présente sur au moins l'une de ses faces au moins une zone revêtue d'une couche de silicone (2). Là encore, de manière parfaitement connue pour un homme du métier, la zone de silicone (2) peut être appliquée sur le support textile (1) par un procédé d'enduction, sans pour cela exclure d'autres procédés. L'épaisseur de la couche de silicone peut être de l'ordre de 0 5 mm environ. Les caractéristiques en tant que telles de la zone siliconée sont du type de celles couramment utilisées par exemple dans le domaine vestimentaire pour obtenir un effet antiglisse comme cela peut être le cas pour les bas ou chaussettes de contention ou non.The textile complex (1) which can be, for example, in the form of a strip, has on at least one of its faces at least one zone coated with a silicone layer (2). Again, in a manner well known to one skilled in the art, the silicone zone (2) can be applied to the textile support (1) by a coating process, without excluding other methods. The thickness of the silicone layer may be of the order of about 0.5 mm. The characteristics as such of the silicone zone are of the type commonly used for example in the clothing field to obtain an anti-slip effect as may be the case for stockings or compression socks or not.

Selon les caractéristiques à la base de l'invention, la zone revêtue de la couche de silicone (2) présente une pluralité de micros perforations (3). Ces micros perforations (3) ont pour fonction de faciliter l'évacuation de la sueur.According to the characteristics underlying the invention, the zone coated with the silicone layer (2) has a plurality of micro-perforations (3). These micro perforations (3) have the function of facilitating the evacuation of sweat.

La zone revêtue de la couche de silicone (2) peut avantageusement recevoir un film protecteur (4). Dans ce cas, les micros perforations (3) sont réalisées à la fois dans l'épaisseur du film (4) et de la zone siliconée (2). Le film protecteur de tout type connu et approprié, est non étirable ce qui permet d'assurer un blocage mécanique au niveau de la zone revêtue de la couche de silicone, ce qui s'avère important lorsque le complexe textile présente, comme indiqué, des capacités d'allongement pour la réalisation des micros perforations (3).The zone coated with the silicone layer (2) can advantageously receive a protective film (4). In this case, the micro perforations (3) are made both in the thickness of the film (4) and the silicone zone (2). The protective film of any known and suitable type is non-stretchable, which makes it possible to provide mechanical blocking at the zone coated with the silicone layer, which is important when the textile complex has, as indicated, elongation capacities for the realization of the micro perforations (3).

Selon l'invention, les micros perforations (3) sont réalisées en continu à partir d'un poste fixe (5) équipé d'une pluralité d'aiguilles (6). Le complexe (1) est déplacé linéairement en continu par rapport au poste (5). Le poste (5) est assimilable à une machine à coudre, les aiguilles (6) étant montées en combinaison avec un pied compresseur (7) coopérant en appui avec le support textile. Les aiguilles (6) font parties d'une tête et sont disposées selon un nombre de rangées correspondant sensiblement à la largueur de la zone siliconée en étant disposées en alignement linéaire ou non.According to the invention, the micro perforations (3) are made continuously from a fixed station (5) equipped with a plurality of needles (6). The complex (1) is moved linearly continuously with respect to the station (5). The station (5) is similar to a sewing machine, the needles (6) being mounted in combination with a foot compressor (7) cooperating in support with the textile support. The needles (6) are part of a head and are arranged in a number of rows corresponding substantially to the width of the silicone zone being disposed in linear alignment or not.

A noter que les aiguilles (6) peuvent être de section transversale ronde sans pour cela exclure d'autre forme en fonction du type de micros perforations souhaitées.Note that the needles (6) may be of round cross section without excluding other form depending on the type of micros perforations desired.

Les micros perforations peuvent être réalisées sur un poste indépendant disposé en alignement et en continuité avec le poste d'enduction et de mise en place du film protecteur (figure 3). Dans ce cas, les micros perforations (3) sont réalisées dans la continuité du procédé de fabrication du support textile avec la zone d'enduction et le film protecteur. On n'exclut pas de réaliser les micros perforations sur un poste totalement indépendant de sorte que les micros perforations sont réalisées de manière indépendante et après réalisation du complexe textile avec la zone siliconée et le film protecteur.The micro-perforations can be made on an independent station arranged in alignment and in continuity with the coating station and placing the protective film (Figure 3). In this case, the micro perforations (3) are made in the continuity of the manufacturing process of the textile support with the coating zone and the protective film. It is not excluded to make the micro perforations on a completely independent post so that the micro perforations are performed independently and after completion of the textile complex with the silicone zone and the protective film.

Comme indiqué le complexe peut se présenter sous la forme d'une bande aérée et constituer avantageusement la partie supérieure d'un bas ou d'une chaussette présentant ou non des capacités de contention. La couche de silicone (2) présente des caractéristiques aptes à permettre le maintien du complexe sur la peau d'une personne. Par exemple, les caractéristiques de la couche de silicone sont du type de celles définies dans le brevet FR 2 930 708. Les avantages ressortent bien de la description, en particulier on souligne et on rappelle : l'aération de la partie siliconée du support textile pour permettre l'évacuation de la sueur, les micros perforations n'altèrent pas les caractéristiques de la zone siliconée, - après enlèvement du film protecteur les micros perforations sont quasi invisibles à l'oeil nu, - l'efficacité du résultat obtenu, la possibilité de réaliser les micros perforations indépendamment de la chaîne de fabrication du support textile, l'application du complexe textile à des bandes de fixation pour bas ou chaussettes ayant des capacités de contention ou non sans pour cela exclure d'autres types d'applications dans le domaine vestimentaire ou autre.10As indicated, the complex may be in the form of an airy band and advantageously constitute the upper part of a stocking or sock with or without contention capacities. The silicone layer (2) has characteristics capable of allowing the complex to be maintained on the skin of a person. For example, the characteristics of the silicone layer are of the type defined in patent FR 2 930 708. The advantages are apparent from the description, in particular it is emphasized and recalled: the aeration of the silicone portion of the textile support to allow the evacuation of the sweat, the micro perforations do not alter the characteristics of the silicone zone, - after removal of the protective film micros perforations are almost invisible to the naked eye, - the effectiveness of the result obtained, the possibility of making the micro-perforations independently of the production line of the textile support, the application of the textile complex to fastening strips for stockings or socks having contention capacities or not without excluding other types of applications in this way; the field of clothing or other.10
