Description

La présente invention se rapporte aux machines de production de nontissés comprenant une ou plusieurs tours spun-bond et éventuellement une ou plusieurs têtes melt-blown déposant des filaments et éventuellement des fibres en une nappe sur un convoyeur. La nappe ainsi déposée et encore fragile est envoyée ensuite à une consolidation par jets d'eau.The present invention relates to machines for producing nonwovens comprising one or more spun-bond towers and possibly one or more melt-blown heads depositing filaments and possibly fibers in a web on a conveyor. The tablecloth thus deposited and still fragile is then sent to consolidation by water jets.

Un inconvénient de ces machines est que la nappe qui en sort ne peut pas être envoyée en continu à une unité d'application d'un produit.A disadvantage of these machines is that the sheet that comes out can not be sent continuously to a product application unit.

L'invention remédie à cet inconvénient.The invention overcomes this disadvantage.

L'invention a donc pour objet une machine de production d'un nontissé en continu, comprenant une tour spun-bond déposant des filaments en une nappe sur un convoyeur et un dispositif de consolidation de la nappe, caractérisée par un moyen d'exprimage de l'humidité en aval, dans le sens de déplacement de la nappe, du dispositif de consolidation et par un dispositif d'application d'un produit à la nappe en aval du moyen d'exprimage.The subject of the invention is therefore a machine for producing a continuous nonwoven, comprising a spun-bond tower depositing filaments in a sheet on a conveyor and a device for consolidating the sheet, characterized by a means for expressing the moisture downstream, in the direction of movement of the web, the consolidation device and by a device for applying a product to the web downstream of the squeezing means.

Le moyen d'exprimage est constitué simplement par un deuxième convoyeur sur lequel passe la nappe et entre les brins supérieur et inférieur desquels est ménagé un dispositif à dépression, donnant notamment un vide compris entre 40 et 700 millibar, soumettant la nappe à un effet d'aspiration.The expressing means is constituted simply by a second conveyor on which the web passes and between the upper and lower strands of which is formed a vacuum device, giving in particular a vacuum of between 40 and 700 millibar, subjecting the web to an effect of suction.

Grâce à cela on peut maintenant faire subir en continu à des nappes constituées de filaments hydrophobes par exemple en polypropylène, en polyéthylène ou en métallocène, un traitement ultérieur par un agent tensioactif et/ou un liant et/ou un agent lubrifiant et/ou un agent gonflant et/ou un colorant ou une impression en continu, l'exprimage de l'humidité étant suffisant pour que le produit appliqué par le dispositif d'application s'applique correctement à la nappe même si celle-ci est constituée de filaments hydrophobes.With this it is now possible to continuously subject webs consisting of hydrophobic filaments, for example polypropylene, polyethylene or metallocene, subsequent treatment with a surfactant and / or a binder and / or a lubricant and / or a blowing agent and / or a dye or a continuous printing, the expression of the moisture being sufficient for the product applied by the application device to apply correctly to the web even if it consists of hydrophobic filaments .

On donne au brin supérieur du deuxième convoyeur une longueur telle, en fonction de la vitesse de passage de la nappe, que la teneur en humidité de la nappe devienne inférieure à 70 % en poids, et mieux inférieure à 50 % et encore mieux inférieure à 20 % à la sortie du deuxième convoyeur. Cette teneur en humidité est en général comprise entre 10% et 70% en poids. A la différence de ce que donnerait un séchage, elle est supérieure à 10%. En général, la durée de séjour de la nappe sur le deuxième convoyeur peut être inférieure à 2 secondes pour un convoyeur dont le brin supérieur a une longueur de 2 m par exemple.The upper run of the second conveyor is given such length, depending on the speed of passage of the sheet, that the moisture content of the sheet becomes less than 70% by weight, and better still less than 50% and even better still less than 20% at the exit of the second conveyor. This moisture content is in general between 10% and 70% by weight. Unlike what a drying would give, it is greater than 10%. In general, the residence time of the web on the second conveyor can be less than 2 seconds for a conveyor whose upper run has a length of 2 m for example.

La machine peut comprendre en aval du dispositif d'application d'un produit, un dispositif de séchage de la nappe, ce dispositif de séchage pouvant être rendu moins conséquent par le fait qu'une bonne partie de l'humidité a déjà été exprimée dans le moyen d'exprimage.The machine may comprise, downstream of the device for applying a product, a device for drying the sheet, this drying device being able to be made less consequent by the fact that a good part of the moisture has already been expressed in the means of expression.

Le dispositif d'application du produit est de préférence un dispositif d'application à la mousse, ou au rouleau lécheur ou par pulvérisation qui s'accommodent d'une teneur résiduelle en humidité de la nappe.The product application device is preferably a device for applying to the foam, or to the nap roller or by spraying which accommodate a residual moisture content of the web.

De préférence, pour des produits pour l'hygiène, notamment pour des couches bébés, l'application se fait par bandes longitudinales, ce qui crée une alternance de zones longitudinales hydrophiles et hydrophobes par exemple.Preferably, for hygiene products, especially for baby diapers, the application is made by longitudinal strips, which creates an alternation of longitudinal hydrophilic and hydrophobic zones for example.

A la demande de brevet EP-0 072 691 , on prévoit non pas d'exprimer de l'humidité d'une nappe de non-tissé, c'est-à-dire d'en faire sortir une partie de l'eau par un moyen mécanique, mais de sécher une nappe de non-trissé, c'est-à-dire d'en éliminer la presque totalité de l'eau par apport d'énergie calorifique.At the patent application EP-0 072 691 it is not intended to express the moisture of a nonwoven web, that is to say to extract some of the water by mechanical means, but to dry a sheet of untreated, that is to say, to eliminate almost all the water by providing heat energy.

La figure unique du dessin annexé illustre l'invention.The single figure of the accompanying drawing illustrates the invention.

La figure est une représentation schématique en coupe d'une machine suivant l'invention.The figure is a schematic representation in section of a machine according to the invention.

Elle comprend une tour spun-bond comportant une extrudeuse d'un polymère organique fondu alimentant une filière 1 permettant de produire un rideau de filaments F, une zone 2 de refroidissement permettant d'obtenir la solidification au moins superficielle des filaments extrudés, un dispositif 3 d'aspiration sous la forme d'une chambre à l'intérieur de laquelle le rideau de filaments est soumis à l'action de veines d'air à grande vitesse qui provoquent l'étirage des filaments, et un diffuseur 4 permettant en sortie du dispositif d'aspiration de dévier et ralentir le flux d'air et de répartir les filaments F de manière aléatoire en une nappe se déposant sur le brin 5 supérieur d'un premier convoyeur 6 sans fin. Les filaments se présentent sous la forme d'un faisceau de filaments F, s'étendant perpendiculairement au plan de la figure.It comprises a spun-bond tower comprising an extruder of a molten organic polymer feeding a die 1 for producing a curtain of filaments F, a cooling zone 2 for obtaining the at least superficial solidification of the extruded filaments, a device 3 in the form of a chamber inside which the curtain of filaments is subjected to the action of high velocity air streams which cause the drawing of the filaments, and a diffuser 4 allowing the exit of the suction device to deflect and slow down the flow of air and to distribute the filaments F randomly in a web depositing on the upper strand of a first conveyor 6 endless. The filaments are in the form of a bundle of filaments F, extending perpendicular to the plane of the figure.

Au dessus du brin 5 supérieur, est monté un tambour 7 horizontal avec un dispositif symbolisé par la lettre A de dépression à l'intérieur. La surface latérale du tambour 7 est perforée. Le tambour est entraîné en rotation par rapport à son axe. Le tambour est entouré d'un manchon troué. Deux injecteurs 8 projettent des jets d'eau sous pression sur la face latérale du tambour, la nappe de filaments pouvant passer entre le tambour 7 et les injecteurs 8 et être ainsi consolidée. Les jets peuvent avoir un diamètre compris entre 80 et 170 microns. Le nombre de jets par mètre peut être compris entre 1 000 et 5 000 et la pression d'eau dans les injecteurs peut être comprise entre 10 et 400 bar, tandis que la dépression dans le tambour 7 peut être comprise entre moins 20 millibar et moins 200 millibar et le tambour 7 peut être entraîné à une vitesse comprise entre 1 et 400 m/mn. La nappe passe ensuite sur le brin 9 supérieur d'un deuxième convoyeur 10 pour aller à un deuxième tambour 11 de même structure et de même fonctionnement que le tambour 7. Du tambour 11, la nappe passe sur un tambour 12 muni comme le tambour 11 d'injecteurs. Le tambour 12 est analogue au tambour 11 dans sa structure et dans son fonctionnement.Above the upper strand, is mounted a horizontal drum 7 with a device symbolized by the letter A depression inside. The lateral surface of the drum 7 is perforated. The drum is rotated relative to its axis. The drum is surrounded by a perforated sleeve. Two injectors 8 project jets of water under pressure on the lateral face of the drum, the sheet of filaments can pass between the drum 7 and the injectors 8 and be consolidated. The jets can have a diameter of between 80 and 170 microns. The number of jets per meter can be between 1000 and 5000 and the water pressure in the injectors can be between 10 and 400 bar, while the depression in the drum 7 can be between minus 20 millibar and less. 200 millibar and the drum 7 can be driven at a speed between 1 and 400 m / min. The sheet then passes on the upper strand 9 of a second conveyor 10 to go to a second drum 11 of the same structure and operation as the drum 7. From the drum 11, the sheet passes over a drum 12 provided as the drum 11 injectors. The drum 12 is similar to the drum 11 in its structure and in its operation.

A la sortie du tambour 12, la nappe est envoyée directement à un deuxième convoyeur 15 muni d'un dispositif 16 d'exprimage de l'humidité, à savoir un caisson dans lequel règne un vide de 600 millibar et interposé entre le brin supérieur et le brin inférieur du deuxième convoyeur 15. La face supérieure du caisson a une fente s'étendant transversalement en regard de toute la nappe passant sur le convoyeur et par laquelle l'humidité de celle-ci est aspirée. Le brin supérieur a une longueur de 3 m.. La nappe y passe à une vitesse de 200 m à la minute.At the outlet of the drum 12, the web is sent directly to a second conveyor 15 provided with a device 16 for the expression of moisture, namely a box in which there is a vacuum of 600 millibar and interposed between the upper and the lower side. the lower strand of the second conveyor 15. The upper face of the box has a slot extending transversely facing the entire sheet passing over the conveyor and through which the moisture thereof is sucked. The upper strand has a length of 3 m. The sheet passes there at a speed of 200 m per minute.

En aval de ce convoyeur est prévu un dispositif 17 d'application d'un produit d'anoblissement qui comporte un poste 18 d'application proprement dit du produit, un poste 19 de séchage et un poste 20 d'enroulage.Downstream of this conveyor is provided a device 17 for applying a product of ennoblement which comprises a station 18 proper application of the product, a drying station 19 and a post 20 of winding.

On obtient ainsi en continu un nontissé prêt à l'emploi.Thus, a nonwoven nonwoven is continuously obtained.
