Abstract

An elastic material (2) has a layer (3) of fibres (4) attached to at least one of its faces to control its direction of stretch. The fibres are produced by a 'Spunlace' (RTM) technique and can be of a natural material of vegetable, animal or mineral origin, such as cotton, silk, linen or wool, or they can be of a synthetic material such as polyester, polyamide, polypropylene, rayon or viscose. The elastic material (2) can be a vulcanisable elastomer, with the fibres attached to it by vulcanisation, or it can be a thermoplastic elastomer, with the fibres attached to it by hot pressing.

Description

La présente invention concerne un matériau élastique, pouvant notamment être utilisé sous forme de bande pour la confection des parties élastiques d'articles vestimentaires. Ces articles peuvent être des produits d'hygiène jetables tels que des couches-culottes ou des culottes jetables, des sous-vêtements tels que des slips ou des caleçons, ou des survêtements. The present invention relates to an elastic material, which can in particular be used in the form of a strip for making elastic parts of clothing articles. These articles can be disposable hygiene products such as diapers or disposable pants, underwear such as briefs or underpants, or tracksuits.

De telles bandes doivent, dans certains cas, avoir une déformabilité importante dans une direction longitudinale et une déformabilité très faible, voire nulle, dans une direction transversale, ou inversement. Such strips must, in certain cases, have significant deformability in a longitudinal direction and very low, or even zero, deformability in a transverse direction, or vice versa.

Ainsi, des bandes incorporées longitudinalement dans une couche-culotte jetable doivent pouvoir être étirées dans le sens transversal de la couche, pour assurer la tenue de celle-ci autour du ventre du bébé, sans pouvoir être étirées dans le sens longitudinal. Des pattes adhésives de fermeture de la couche peuvent également comprendre de telles bandes, leur permettant d'être positionnées avec un certain étirement et d'assurer la tenue de la couche autour du ventre du bébé. Thus, strips incorporated longitudinally in a disposable diaper must be able to be stretched in the transverse direction of the diaper, to ensure the holding thereof around the baby's belly, without being able to be stretched in the longitudinal direction. Adhesive tabs for closing the diaper can also include such strips, allowing them to be positioned with a certain stretch and to ensure the holding of the diaper around the baby's belly.

Les ceintures élastiques de sous-vêtements ou de survêtements doivent, au contraire, pouvoir être étirées dans le sens longitudinal, tout en conservant une rigidité transversale leur permettant d'être utilisées correctement par les machines de confection. The elastic belts of underwear or tracksuits must, on the contrary, be able to be stretched in the longitudinal direction, while retaining a transverse rigidity allowing them to be used correctly by the clothing machines.

Pour réaliser une bande de ce type, il est connu de fixer des fils inextensibles ou peu extensibles, espacés entre eux, sur une pièce de matériau élastique, par exemple en caoutchouc naturel ou en élastomère synthétique thermoplastique ou vulcanisé. Ces fils sont orientés dans une direction longitudinale ou transversale de la pièce élastique et permettent de bloquer toute déformation de cette pièce dans cette direction. To make a strip of this type, it is known to fix inextensible or poorly extensible wires, spaced apart, on a piece of elastic material, for example natural rubber or synthetic thermoplastic or vulcanized elastomer. These wires are oriented in a longitudinal or transverse direction of the elastic piece and make it possible to block any deformation of this piece in this direction.

Cette bande donne satisfaction en pratique mais a toutefois pour inconvénient de présenter des risques importants de déchirure au droit des fils de blocage, en cas d'étirement maximal. En effet, le collage des fils empêche un étirement uniforme de la pièce élastique et conduit à l'exercice de contraintes importantes sur celle-ci en cas d'étirement maximal, pouvant aboutir à son déchirement. This strip is satisfactory in practice but has the disadvantage of presenting significant risks of tearing in line with the blocking threads, in the event of maximum stretching. In fact, the bonding of the wires prevents uniform stretching of the elastic part and leads to the exertion of significant stresses on it in the event of maximum stretching, which can lead to its tearing.

De plus, les bandes en élastomère vulcanisable impliquent l'utilisation de talc pour empêcher le collage de leur matériau constitutif sur lui-même lors de la mise en oeuvre de ces bandes et pour éviter le phénomène dit de "blocking". Ce talc est à l'origine de problèmes de collage des bandes avec les parties correspondantes des articles vestimentaires. In addition, the vulcanizable elastomer strips imply the use of talc to prevent sticking of their constituent material on itself during the use of these strips and to avoid the phenomenon known as "blocking". This talc is at the origin of problems of sticking of the bands with the corresponding parts of the clothing articles.

La bande existante précitée a en outre un aspect visuel et un toucher qui ne sont pas très attractifs. The aforementioned existing strip also has a visual appearance and a touch which are not very attractive.

La présente invention vise à remédier à l'ensemble de ces inconvénients. The present invention aims to remedy all of these drawbacks.

Le matériau qu'elle concerne est du type comprenant une pièce élastique sur laquelle sont fixés des moyens inextensibles ou peu extensibles permettant de bloquer la déformation de cette pièce dans une direction déterminée. The material it relates to is of the type comprising an elastic piece on which are fixed inextensible or poorly extensible means making it possible to block the deformation of this piece in a determined direction.

Selon l'invention, ce matériau comprend au moins une nappe de fibres agglomérées orientées principalement dans une direction, cette nappe étant fixée sur au moins une des faces de la pièce élastique de telle manière que la direction d'orientation principale des fibres coïncide avec la direction de blocage souhaitée. According to the invention, this material comprises at least one ply of agglomerated fibers oriented mainly in one direction, this ply being fixed on at least one of the faces of the elastic piece in such a way that the direction of main orientation of the fibers coincides with the desired locking direction.

Cette nappe présente une résistance à la traction importante et est inextensible, ou faiblement extensible, dans ladite direction principale d'orientation des fibres. This ply has a high tensile strength and is inextensible, or weakly extensible, in said main direction of orientation of the fibers.

Elle permet ainsi de bloquer la déformation de la pièce élastique dans cette direction. Par contre, elle ne présente qu'une simple homogénéité de structure à l'état statique, avec une résistance à la traction très faible ou quasi-nulle, dans une direction transversale à cette direction principale d'orientation des fibres. Il en résulte que les fibres peuvent jouer les unes par rapport aux autres dans cette direction transversale, et qu'elles ne s'opposent donc pas à l'étirement de la pièce élastique.It thus makes it possible to block the deformation of the elastic part in this direction. On the other hand, it presents only a simple structural homogeneity in the static state, with a very low or almost zero tensile strength, in a direction transverse to this main direction of orientation of the fibers. As a result, the fibers can play with respect to each other in this transverse direction, and that they therefore do not oppose the stretching of the elastic piece.

Ces fibres permettent un accrochage mécanique de la nappe sur la pièce élastique uniformément réparti sur les surfaces en contact. La nappe de fibres se trouve donc associée à la pièce élastique sans qu'il soit besoin de recourir à un collage. L'uniformité de cet accrochage supprime les contraintes localisées lors de l'étirement du matériau, donc les risques de déchirure. These fibers allow mechanical attachment of the sheet on the elastic piece uniformly distributed over the contacting surfaces. The sheet of fibers is therefore associated with the elastic piece without the need for gluing. The uniformity of this attachment eliminates the localized stresses during the stretching of the material, therefore the risks of tearing.

La pièce de matériau élastique peut être en élastomère vulcanisable, notamment en caoutchouc. The piece of elastic material can be made of vulcanizable elastomer, in particular rubber.

L'accrochage mécanique de la nappe sur elle est alors réalisé par la vulcanisation. La pièce de matériau élastique peut également être en un élastomère thermoplastique. Dans ce cas, sa liaison avec la nappe s'effectue par pressage à chaud.The mechanical attachment of the sheet on it is then carried out by vulcanization. The piece of elastic material can also be made of a thermoplastic elastomer. In this case, its connection with the web is effected by hot pressing.

De préférence, les dimensions de la nappe correspondent sensiblement à celles de la pièce élastique, de sorte que la nappe recouvre sensiblement l'ensemble de la surface de cette pièce. Lors de la mise en oeuvre de pièces élastiques en élastomère vulcanisable, tout risque de collage du matériau lui-même est ainsi évité, ainsi que tout phénomène dit de "blocking", rendant inutile de procéder à un talquage de la pièce élastique. Les problèmes de collage qui résultent de l'utilisation de talc sont ainsi supprimés. La nappe confère en outre au matériau selon l'invention la douceur au toucher de ses fibres agglomérées, ce qui rend ce matériau particulièrement appropriée à la confection de parties élastiques d'articles d'hygiène. Preferably, the dimensions of the ply correspond substantially to those of the elastic piece, so that the ply substantially covers the entire surface of this piece. During the implementation of elastic pieces of vulcanizable elastomer, any risk of sticking of the material itself is thus avoided, as well as any phenomenon called "blocking", making it unnecessary to talc the elastic piece. The bonding problems which result from the use of talc are thus eliminated. The ply also gives the material according to the invention the soft feel of its agglomerated fibers, which makes this material particularly suitable for making elastic parts of hygiene articles.

La nappe peut être obtenue par la technique dite "SPUNLACE", ou par toute technique équivalente permettant d'obtenir des nappes présentant des fibres agglomérées orientées principalement dans une direction. Ses fibres peuvent être en matériau naturel, d'origine végétale, animale ou minérale, tel que notamment coton, soie, lin, laine, etc..., ou être en un matériau synthétique, tel que polyester, polyamide, polypropylène, rayonne, viscose, etc... Les fibres peuvent être liées par toute technique appropriée, notamment par liage mécanique et/ou chimique et/ou thermique. En outre, le grammage de la nappe peut varier en fonction des besoins, notamment entre 20 à 50 g/m2.  The sheet can be obtained by the so-called "SPUNLACE" technique, or by any equivalent technique making it possible to obtain sheets having agglomerated fibers oriented mainly in one direction. Its fibers can be of natural material, of vegetable, animal or mineral origin, such as in particular cotton, silk, linen, wool, etc., or can be of a synthetic material, such as polyester, polyamide, polypropylene, rayon, viscose, etc. The fibers can be linked by any suitable technique, in particular by mechanical and / or chemical and / or thermal bonding. In addition, the grammage of the web can vary according to needs, in particular between 20 to 50 g / m2.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une bande du matériau élastique qu'elle concerne. For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a strip of the elastic material which it relates.

La figure 1 en est une vue en perspective, avec décollement partiel de ses trois couches constitutives, et
la figure 2 en est une vue à plat, avec étirement transversal.FIG. 1 is a perspective view thereof, with partial detachment of its three constituent layers, and
Figure 2 is a flat view, with transverse stretching.

Les figures représentent, sous différents angles, une bande 1 de matériau élastique, pouvant notamment être utilisée pour la confection des parties élastiques d'articles d'hygiène. The figures represent, from different angles, a strip 1 of elastic material, which can in particular be used for making elastic parts of hygiene articles.

Cette bande 1 comprend une feuille élastique 2 et deux nappes 3 de fibres 4. This strip 1 comprises an elastic sheet 2 and two sheets 3 of fibers 4.

La feuille 2 est en élastomère thermoplastique de faible épaisseur, par exemple de 0,2 mm d'épaisseur, et est isotrope, c'est-à-dire peut être étirée de manière égale dans toutes les directions. The sheet 2 is made of thin thermoplastic elastomer, for example 0.2 mm thick, and is isotropic, that is to say can be stretched equally in all directions.

Au sein de chaque nappe 3, les fibres 4 sont orientées principalement dans une direction. Elles sont en polypropylène et sont agglomérées par une technique de liage appropriée, notamment par la technique dite "SPUNLACE". Chaque nappe 3 présente ainsi une résistance importante à la traction et est inextensible, ou faiblement extensible, dans la direction d'orientation principale des fibres 4, et ne présente qu'une simple homogénéité de structure à l'état statique, avec une résistance à la traction quasi-nulle, dans une direction transversale à cette direction d'orientation principale des fibres 4. Within each sheet 3, the fibers 4 are oriented mainly in one direction. They are made of polypropylene and are agglomerated by an appropriate binding technique, in particular by the so-called "SPUNLACE" technique. Each ply 3 thus has a high tensile strength and is inextensible, or weakly extensible, in the direction of main orientation of the fibers 4, and has only a simple structural homogeneity in the static state, with resistance to almost zero traction, in a direction transverse to this direction of main orientation of the fibers 4.

Chacune des nappes 3 présente des dimensions correspondant sensiblement à celles de la feuille 2, de sorte qu'elle recouvre l'ensemble de la surface de cette feuille 2, et est fixée à l'une des faces de la feuille 2 de manière telle que la direction d'orientation principale des fibres 4 coïncide avec la direction longitudinale de la bande 1. Each of the plies 3 has dimensions corresponding substantially to those of the sheet 2, so that it covers the entire surface of this sheet 2, and is fixed to one of the faces of the sheet 2 so that the main direction of orientation of the fibers 4 coincides with the longitudinal direction of the strip 1.

Cette fixation est réalisée par chauffage de la feuille 2 et pressage à chaud de l'ensemble. This fixing is carried out by heating the sheet 2 and hot pressing of the assembly.

Les deux nappes 3 permettent de bloquer la déformation de la pièce élastique 2 dans la direction d'orientation principale des fibres 4. Par contre, les fibres 4 peuvent jouer les unes par rapport aux autres dans une direction transversale à cette direction d'orientation principale des fibres 4, comme le montre la figure 2, et ne s'opposent donc pas à l'étirement de la pièce élastique 2. The two plies 3 make it possible to block the deformation of the elastic part 2 in the direction of main orientation of the fibers 4. On the other hand, the fibers 4 can play with respect to each other in a direction transverse to this direction of main orientation fibers 4, as shown in FIG. 2, and therefore do not oppose the stretching of the elastic piece 2.

La bande 1 est ainsi anisotrope, c'est-à-dire est déformable uniquement dans sa direction transversale, ce qui permet son utilisation par exemple pour la confection de produits d'hygiène jetables, au moyen de machines appropriées. The strip 1 is thus anisotropic, that is to say is deformable only in its transverse direction, which allows its use for example for the preparation of disposable hygiene products, by means of suitable machines.

Les fibres 4 permettent la fixation des nappes 3 en de nombreux points de la pièce 2, répartis sur une surface importante. Tout collage localisé des fibres 4 est ainsi rendu inutile, ce qui, conjointement à la possibilité de jeu relatif précité des fibres 4, permet un étirement uniforme de la feuille 2, sans exercice de contrainte localisée, et donc sans risque de déchirement. The fibers 4 allow the sheets 3 to be fixed at numerous points in the part 2, distributed over a large area. Any localized bonding of the fibers 4 is thus rendered unnecessary, which, together with the aforementioned possibility of relative play of the fibers 4, allows a uniform stretching of the sheet 2, without the exercise of localized stress, and therefore without risk of tearing.

Grâce à ces nappes 3, la bande 1 a en outre un bon aspect visuel et une douceur au toucher qui la rendent particulièrement appropriée à la confection de parties élastiques d'articles d'hygiène.  Thanks to these plies 3, the strip 1 also has a good visual appearance and a softness to the touch which make it particularly suitable for making elastic parts of hygiene articles.
