Description

"Game textile de protection acoustique" "Acoustic protection textile game"
La présente invention concerne une gaine textile de protection acoustiqueThe present invention relates to a textile sheath for acoustic protection
De manière générale, l'invention concerne des enveloppes protectrices telles que des gaines en tissu tissé, tricoté ou tresse, qui permettent de protéger des produits soumis à des vibrations, créant un bruit indésirable. Plus particulièrement, la présente invention s'applique à des produits du type gaine adaptés à recouvrir des éléments allongés tels que des fils métalliques ou des câbles, éventuellement disposes en faisceauxIn general, the invention relates to protective envelopes such as sheaths in woven, knitted or braided fabric, which make it possible to protect products subjected to vibrations, creating an undesirable noise. More particularly, the present invention applies to products of the sheath type suitable for covering elongated elements such as metal wires or cables, possibly arranged in bundles.
De telles gaines de textile sont couramment utilisées dans l'industrie automobile où elles permettent d'enfermer des fils ou des tubes métalliques dans des espaces confinesSuch textile sheaths are commonly used in the automotive industry where they allow metal wires or tubes to be enclosed in confined spaces
Un tel exemple de gaine textile est décrit dans le brevet européen EP 0 472 61 1One such example of textile sheath is described in European patent EP 0 472 61 1
Cette gaine permet de protéger et d'envelopper des faisceaux de tuyaux, tubes ou fils électriques utilisés dans des conditions d'abrasion et de vibration importantes, dans un espace confiné, à l'intérieur de la portière d'une automobile par exempleThis sheath makes it possible to protect and wrap bundles of pipes, tubes or electrical wires used in conditions of significant abrasion and vibration, in a confined space, inside the door of an automobile for example.
Cette gaine est formée d'un premier fil du type multifilament et d'un second fil du type monofilament, les deux fils étant de préférence combinés par tricotage ou tressage De telles gaines s'ajustent correctement sur les faisceaux de fils et procurent une bonne absorption des vibrations acoustiquesThis sheath is formed of a first thread of the multifilament type and of a second thread of the monofilament type, the two threads preferably being combined by knitting or braiding. Such sheaths fit correctly on the bundles of threads and provide good absorption. acoustic vibrations
La présente invention a pour but de proposer une gaine textile permettant une protection acoustique amélioréeThe present invention aims to provide a textile sheath allowing improved acoustic protection
La gaine textile de protection acoustique visée par l'invention comprend des fils d'un premier type comprenant un monofilament et des fils d'un second type comprenant un multifilamentThe textile acoustic protection sheath targeted by the invention comprises yarns of a first type comprising a monofilament and yarns of a second type comprising a multifilament
Conformément a l'invention, la gaine est formée d'une structure textile ayant une distribution dissymétrique des fils du premier et second type sur l'une et l'autre face de la gaine Grâce à cette répartition dissymétrique des deux types de fils, chacun des deux types de fils peut être disposé preférentiellement sur l'une ou l'autre des faces de la gaine, en fonction notamment de ses caractéristiques physiques et mécaniques Selon une caractéristique préférée de l'invention, les fils du premier type sont majoritairement distribués sur une face intérieure de la gaine et les fils du second type sont majoritairement distribues sur une face extérieure de la gaineAccording to the invention, the sheath is formed of a textile structure having an asymmetrical distribution of the son of the first and second type on both sides of the sheath Thanks to this asymmetrical distribution of the two types of son, each of the two types of son can be preferably placed on one or the other of the faces of the sheath, according in particular to its physical and mechanical characteristics. According to a preferred characteristic of the invention, the wires of the first type are mainly distributed on an inner face of the sheath and the wires of the second type are mainly distributed on an outer face of the sheath
Ainsi, le monofilament, qui sert principalement a donner sa forme a la gaine, est présent à l'intérieur de la gaine II est destiné à venir en contact avec un élément à protéger, tel qu'un faisceau de fils, et permet à la gaine d'épouser correctement cet élémentThus, the monofilament, which is mainly used to give its shape to the sheath, is present inside the sheath II is intended to come into contact with an element to be protected, such as a bundle of wires, and allows the sheath to properly marry this item
En revanche, les multifilaments, qui confèrent principalement a la gaine ses caractéristiques d'absorption vibratoire, sont majoritairement disposés a l'extérieur de la gaine Selon une autre caractéristique préférée de l'invention, la structure textile est une structure tissée ayant une distribution dissymétrique des fils de trame et des fils de chaîne sur l'une et l'autre face de la gaine.On the other hand, the multifilaments, which mainly confer on the sheath its vibratory absorption characteristics, are mainly arranged outside the sheath. According to another preferred characteristic of the invention, the textile structure is a woven structure having an asymmetrical distribution. weft threads and warp threads on both sides of the sheath.
Une telle structure permet d'obtenir par tissage une répartition dissymétrique de deux types de fils sur l'une et l'autre face de la gaine Contrairement à des tissus classiques du type toile, dans lesquels la répartition symétrique des fils de trame et des fils de chaîne est obtenue par un croisement régulier de chacun de ces fils, on obtient une structure tissée plus souple dans laquelle notamment les fils multifilamentaires sont moins comprimes et conservent leur volume garant d'une bonne protection acoustique Selon une caractéristique avantageuse de l'invention, la structure tissée présente un décalage dans une direction perpendiculaire aux fils de trame des liages d'un fil de chaîne a un fil de chaîne voisinSuch a structure makes it possible to obtain, by weaving, an asymmetrical distribution of two types of threads on both sides of the sheath Unlike conventional fabrics of the canvas type, in which the symmetrical distribution of the weft threads and the threads chain is obtained by regular crossing of each of these threads, a more flexible woven structure is obtained in which in particular the multifilament threads are less compressed and retain their volume guaranteeing good acoustic protection. According to an advantageous characteristic of the invention, the woven structure has an offset in a direction perpendicular to the weft threads of the bindings of a warp thread to a neighboring warp thread
On obtient ainsi une orientation des fils de chaîne sur une face du produit qui limite les risques d'accrochage de cette gaine textile lors de sa mise en placeAn orientation of the warp threads is thus obtained on one face of the product which limits the risks of catching this textile sheath during its installation.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-apres Aux dessins annexés, donnés à titre d'exemples non limitatifsOther features and advantages of the invention will appear in the description below In the accompanying drawings, given by way of nonlimiting examples

Une portion de gaine textile de protection acoustique conforme a l'invention est illustrée a la figure 1A portion of textile acoustic protection sheath according to the invention is illustrated in FIG. 1
Cette gaine textile 10 comprend deux types de fils Les fils du premier type 1 1 comprennent un monofilament alors que les fils du second type 12 comprennent un multifilamentThis textile sheath 10 comprises two types of yarns The yarns of the first type 1 1 comprise a monofilament while the yarns of the second type 12 comprise a multifilament
Dans de telles gaines textiles de protection acoustique, les fils monofilamentaires sont utilisés classiquement pour leur propriété élastique, alors que les fils multifilamentaires sont utilises principalement pour l'atténuation des vibrations, et notamment la protection acoustique des éléments loges dans la gaineIn such textile acoustic protection sheaths, monofilament yarns are conventionally used for their elastic property, while multifilament yarns are used mainly for the attenuation of vibrations, and in particular the acoustic protection of the elements housed in the sheath
Conformément à l'invention, la gaine 10 est formée d'une structure textile qui présente une distribution dissymétrique des fils du premier type 1 1 et des fils du second type 12 sur l'une et l'autre face de cette gaine 10 Dans ce mode de réalisation, la structure textile est une structure tissée ayant une distribution dissymétrique de ces fils de trame et fils de chaîneAccording to the invention, the sheath 10 is formed of a textile structure which has an asymmetrical distribution of the son of the first type 1 1 and the son of the second type 12 on both sides of this sheath 10 In this embodiment, the textile structure is a woven structure having an asymmetrical distribution of these weft threads and warp threads
Une telle distribution dissymétrique est obtenue par exemple pour une structure tissée a armure sergee telle qu'illustrée a la figure 2Such an asymmetrical distribution is obtained for example for a woven structure with twill weave as illustrated in FIG. 2
Sur cette représentation schématique d'une armure sergee, les fils de trame 1 1 sont représentes horizontalement alors que les fils de chaîne 12 sont représentes verticalement L'armure sergee est caractérisée notamment par le fait que le liage d'un premier fil de chaîne est répète sur un deuxième fil de chaîne voisin avec un décalage d'une duite (portion de fil de trame 1 1 entre les lisières du tissu), dans une direction perpendiculaire au fil de trame Ce décalage est répète ainsi de fil de chaîne en fil de chaîne voisinIn this schematic representation of a twill weave, the weft threads 1 1 are shown horizontally while the warp threads 12 are shown vertically The twill weave is characterized in particular by the fact that the binding of a first warp thread is repeated on a second neighboring warp thread with an offset of one pick (portion of weft thread 1 1 between the edges of the fabric) , in a direction perpendicular to the weft yarn This offset is thus repeated from warp yarn to neighboring warp yarn
Comme illustre à la figure 2, un tissu d'armure sergee présente ainsi des raies obliques sur l'endroit du tissu, appelées "côtes"As illustrated in FIG. 2, a twill weave fabric thus has oblique stripes on the right side of the fabric, called "ribs"
On a illustré ici un sergé de 4 (le motif de liage est répète sur chaque groupe de quatre fils de chaîne voisins) a effet chaîne, c'est-à-dire que les fils de chaîne 12 prédominent sur l'endroit du tissuA twill of 4 has been illustrated here (the tying pattern is repeated on each group of four neighboring warp threads) with warp effect, that is to say that the warp threads 12 predominate over the place of the fabric.
Comme illustrée a la figure 3, la structure tissée pourrait également avoir une armure satinAs illustrated in Figure 3, the woven structure could also have a satin weave
La structure tissée a armure satin se distingue par la présence d'un décalage constant dans une direction perpendiculaire au fil de trame 1 1 des liages d'un fil de chaîne 12 à un fil de chaîne voisin 12The woven structure with satin weave is distinguished by the presence of a constant offset in a direction perpendicular to the weft thread 1 1 of the bindings of a warp thread 12 to a neighboring warp thread 12
Cet intervalle constant est appelé "décochement"This constant interval is called "dropout"
Ce décochement indique de combien de duites le point de croisement ou liage est déplace vers le haut entre deux fils de chaîne 12 voisins, de gauche a droite sur l'endroit du tissu On a illustré ici, à titre d'exemple, un satin de 5 (le motif de liage est répète sur chaque groupe de cinq fils de chaîne voisins), avec un décochement de 3 et à effet de chaîneThis notch indicates by how many picks the crossing point or binding is moved up between two neighboring warp threads 12, from left to right on the right side of the fabric. We have illustrated here, by way of example, a satin of 5 (the tying pattern is repeated on each group of five neighboring warp threads), with a check mark of 3 and with warp effect
Dans les deux exemples de textile à distribution dissymétrique illustrés aux figures 2 et 3, les fils de trame 1 1 sont des fils du premier type comprenant un monofilament et les fils de chaîne 12 sont des fils du second type comprenant un multifilamentIn the two examples of asymmetric distribution textile illustrated in FIGS. 2 and 3, the weft threads 1 1 are threads of the first type comprising a monofilament and the warp threads 12 are threads of the second type comprising a multifilament
Dans ces deux structures textiles, les fils du second type ou fils de chaîne 12 sont majoritairement situes sur l'endroit de la structure tissée, destine a devenir la face extérieure de la gaine Réciproquement, les fils du premier type ou fils de trame sont majoritairement distribues sur l'envers de la structure tissée, destine a devenir la face intérieure de la gaine Les fils du premier type 11 sont ici constitués d'un monofilament unique thermoplastique.In these two textile structures, the yarns of the second type or warp yarns 12 are mainly located on the place of the woven structure, intended to become the outer face of the sheath Conversely, the yarns of the first type or weft yarns are mainly distributed on the back of the woven structure, intended to become the inside of the sheath The son of the first type 11 here consist of a single thermoplastic monofilament.
Ce monofilament confère à la gaine son aspect élastique ainsi qu'un aspect autofermable comme cela sera décrit ci-après. Ce monofilament peut être en polyester, polyamide, polyéthylène, polypropylene, polyketones, polysulphone ou tout autre polymère ou encore un mélange de ceux-ci.This monofilament gives the sheath its elastic appearance as well as a self-closing appearance as will be described below. This monofilament can be made of polyester, polyamide, polyethylene, polypropylene, polyketones, polysulphone or any other polymer or a mixture of these.
Le diamètre de ce monofilament thermoplastique est compris entre 0,1 et 0,5 mm, et de préférence entre 0,15 et 0,30 mm. Eventuellement, les fils de premier type 11 peuvent comprendre, outre ce monofilament, un ou plusieurs autres monofilaments ou multifilaments.The diameter of this thermoplastic monofilament is between 0.1 and 0.5 mm, and preferably between 0.15 and 0.30 mm. Optionally, the first type yarns 11 can comprise, in addition to this monofilament, one or more other monofilaments or multifilaments.
Les fils du second type 12 comprennent en revanche au moins 80 %, et de préférence 100 %, de multifilaments.The yarns of the second type 12, on the other hand, comprise at least 80%, and preferably 100%, of multifilaments.
Ces fils multifilamentaires permettent d'obtenir une bonne atténuation des vibrations acoustiques, et procurent également au textile une caractéristiqueThese multifilament yarns provide good attenuation of acoustic vibrations, and also give the textile a characteristic
"antibattement" et "antifrottement"."anti-tilt" and "anti-friction".
Le multifilament peut être composé de matière naturelle ou artificielle ou d'un mélange des deux en fonction des applications d'utilisation de la gaine textile. De préférence, on utilisera un multifilament texture afin d'augmenter son gonflant pour mieux atténuer les vibrations.The multifilament can be composed of natural or artificial material or of a mixture of the two according to the applications of use of the textile sheath. Preferably, a textured multifilament will be used in order to increase its bulk to better attenuate the vibrations.
Comme illustré à la figure 4, on obtient ainsi une gaine textile 10 qui permet de protéger un ensemble d'éléments allongés tels que des faisceaux électriques 13 souvent utilisés dans l'automobile. De préférence, cette gaine textile 10 forme une gaine tubulaire obtenue par formage d'une structure textile tissée à plat.As illustrated in FIG. 4, a textile sheath 10 is thus obtained which makes it possible to protect a set of elongated elements such as electrical harnesses 13 often used in the automobile. Preferably, this textile sheath 10 forms a tubular sheath obtained by forming a textile structure woven flat.
On obtient ainsi une gaine ouverte 10, autofermable grâce à une portion de recouvrement 14 telle qu'illustrée à la figure 4.An open sheath 10 is thus obtained, self-closing thanks to a covering portion 14 as illustrated in FIG. 4.
Cette structure de gaine ouverte et autofermable facilite le positionnement de cette gaine 10 autour de faisceaux d'éléments allongés 13.This open and self-closing sheath structure facilitates the positioning of this sheath 10 around bundles of elongated elements 13.
En outre, les extrémités 10a de la gaine textile 10 sont de préférence cautérisées par une coupe à chaud. La mise à longueur de la gaine, après formage, peut être réalisée en coupant celle-ci au moyen d'une lame chauffée, par exemple par passage d'un courant électriqueIn addition, the ends 10a of the textile sheath 10 are preferably cauterized by hot cutting. The sheathing can be cut to length, after forming, by cutting it by means of a heated blade, for example by passing an electric current
Cette coupe à chaud de la gaine permet d'éviter tout effilochage grâce aux extrémités des fils qui sont soudéesThis hot cut of the sheath makes it possible to avoid any fraying thanks to the ends of the wires which are welded
La gaine textile ainsi obtenue conformément à l'invention permet d'obtenir une répartition des monofilaments 1 1 preférentiellement situés à l'intérieur de la gaine, sur une face adaptée à venir en contact avec les faisceaux d'éléments allongés 13 à protéger En revanche, les multifilaments 12, dont le gonflant et le volume permettent d'atténuer significativement les vibrations acoustiques, sont disposes sur la surface extérieure de la gaine 10The textile sheath thus obtained in accordance with the invention makes it possible to obtain a distribution of the monofilaments 1 1 preferably located inside the sheath, on a face adapted to come into contact with the bundles of elongated elements 13 to be protected. , the multifilaments 12, whose bulk and volume make it possible to significantly attenuate the acoustic vibrations, are arranged on the outer surface of the sheath 10
En outre, le décalage des points de liage ou croisements obtenu grâce aux structures tissées décrites précédemment, permet de créer des raies obliques ou une surface lisse, sur l'extérieur de la gaine 10In addition, the offset of the binding points or crossings obtained thanks to the woven structures described above, makes it possible to create oblique lines or a smooth surface on the outside of the sheath 10
Cette gaine 10 offre ainsi une meilleure résistance a l'abrasion et à l'accrochage de sa surfaceThis sheath 10 thus offers better resistance to abrasion and to the attachment of its surface.
La gaine textile conforme à l'invention permet d'augmenter significativement la protection acoustique des éléments en faisceaux Ainsi, en comparaison d'une toile classique tissée permettant d'obtenir par exemple une atténuation des vibrations de l'ordre de 30 dB (A), une gaine ayant une structure textile dissymétrique conforme à l'invention permet d'obtenir des atténuations supérieures à 43 dB (A)The textile sheath according to the invention makes it possible to significantly increase the acoustic protection of the elements in bundles. Thus, in comparison with a conventional woven fabric making it possible, for example, to attenuate vibrations of the order of 30 dB (A). , a sheath having an asymmetrical textile structure in accordance with the invention makes it possible to obtain attenuations greater than 43 dB (A)
Bien entendu, de nombreuses modifications peuvent être apportées aux exemples décrits ci-dessus sans sortir du cadre de l'inventionOf course, numerous modifications can be made to the examples described above without departing from the scope of the invention.
Ainsi, tout type d'armure tissée dissymétrique peut être utilisé pour réaliser la gaine, et notamment d'autres serges ou satins que ceux décritsThus, any type of asymmetrical woven weave can be used to make the sheath, and in particular other serges or satins than those described
D'autres textiles pourraient également être utilises, obtenus par exemple par tricotage ou tressage, des lors qu'ils procurent une distribution dissymétrique des fils sur les faces de la gaine Une structure externe lisse ou à côtes obliques pourrait également être obtenue avec une structure tissée symétrique, notamment un sergé sans envers, ou croiséOther textiles could also be used, obtained for example by knitting or braiding, as long as they provide an asymmetrical distribution of the threads on the faces of the sheath A smooth external structure or with oblique ribs could also be obtained with a symmetrical woven structure, in particular a twill without backing, or crossed
La gaine textile obtenue avec une telle structure est plus résistante à l'abrasion et aux risques d'accrochage, notamment lors de sa mise en placeThe textile sheath obtained with such a structure is more resistant to abrasion and to the risks of snagging, in particular during its installation.
Enfin, la gaine textile pourrait éventuellement être tissée sous une forme tubulaire Finally, the textile sheath could possibly be woven in a tubular form
