Definitions
- the present invention relates to a process for manufacturing a textile-based fusible product by hot spot coating.
- Iron-on textile-based products are now commonly used in the clothing industry and allow, for example, the production of linings or reinforcing fabrics which can be heat sealed.
- a first category of processes consist in the direct application to the textile support of a melt of thermoplastic polymer. It is for example known for the implementation of this process to bring a mass of polymers to a temperature higher than its melting temperature, to distribute it in the cavities of a gravure cylinder (debossed), to scrape the surface of this cylinder and put it in contact with the textile support on which the polymer dots must be applied.
- this method does not make it possible to obtain a coating by quality points.
- the action of the scraper does not completely eliminate traces of polymer on the smooth surfaces of the cylinder. Residues of hot polymer remain on these surfaces and come into contact with the textile support.
- the textile support in contact with the gravure cylinder, loses fibers which adhere to the cylinder, contribute to its fouling and can even remove the scraping of the cylinder which produces a layer of continuous adhesive polymer which is then deposited on the support.
- the quality of the product obtained is low and ill-suited to its use in the clothing sector.
- the mass of polymer contained in the cavities, brought into contact with the textile support adheres thereto, which contributes to empty the cavity and to deposit the points on the textile support.
- Aerated textiles, or with gaps or voids do not ensure uniform adhesion of the polymer contained in all the cavities. Some of them are then not properly emptied, which leads to coating defects.
- thermoadhesive textile products in which the adhesive is deposited in the form of powder or aqueous solution, in points, on the support. After this deposition, the assembly is brought to a high temperature causing the polymer to melt and adhere to the support.
- Patent FR 2 586 717 describes a process of this last category in which drops of a dispersion of fusible material are first deposited on a non-stick transfer support, the drops are then heated on the transfer support and then brings the drops of adhesive into contact with the textile substrate.
- the object of the present invention is a method and an apparatus which simultaneously present the advantages of the "HOT MELT” coating method, in addition to avoiding the grinding of polymers and the advantages of the transfer method, in particular of put the textile in direct contact with the engraved cylinder and avoid bringing the textile support to a high temperature.
- the method and apparatus of the invention also make it possible to carry out a coating by points having little or no defects, that is to say those whose points are regularly distributed and the support is not adhesive outside the points .
- a method of manufacturing a textile-based fusible product is proposed by hot spot coating of the type in which a fusible polymer is melted, a gravure cylinder engraved in a hot hollow is filled with said thermoadhesive polymer, the surface of the cylinder scraped.
- the fusible polymer is deposited in the form of dots on a non-stick transfer mat by the rotogravure cylinder and the dots of fusible polymer are then brought into contact with the support so as to ensure their transfer thereon.
- this apparatus includes a non-stick mat ensuring the transfer of the fusible polymer dots from the rotogravure cylinder to the textile support and allowing these points to be partially cooled.
- the method of the invention allows the manufacture of a textile-based fusible product particularly intended for the clothing industry.
- This type of product has a textile base coated with a heat-bonding polymer.
- the point coating makes it possible to obtain a quality fusible textile which, during its final use after laminating on another textile, provides the flexibility and touch sought after by manufacturers.
- a good coating by points requires on the one hand the adhesion of each point of polymer on the support and must make it possible to avoid the deposit of adhesive outside these points.
- the textile-based fusible product After its manufacture, the textile-based fusible product is stored at room temperature and it is then necessary that the different layers of this product in contact do not adhere to each other.
- the process of the invention is of the "HOT MELT” type, that is to say that a fusible polymer 1 is melted and then used to fill the cavities 20 of a gravure cylinder 2 engraved in the hollow.
- the gravure cylinder 2 was directly brought into contact with the textile support 3.
- the temperature of the coating cylinder 2 is then a compromise. It must be high enough to allow the fusible polymer to be kept in the molten state so that it does not remain in the cavities of the cylinder and must not be too high so as to avoid the crossing of the textile support or even damage. of it.
- This dissociation simultaneously causes the dissociation of the stresses explained above concerning the temperature of the cylinder 2 and / or of the heat-bonding polymer, distributing these stresses in the two successive phases.
- the implementation of the method is then greatly facilitated and makes it possible to obtain satisfactory results.
- the fusible polymer 1 is deposited in the form of dots 4 on a transfer mat 5 partially non-stick, the dots of fusible polymer 4 are then brought into contact with the textile support 3 so as to ensure their transfer to this one.
- the transfer mat 5 is partially non-stick any surface having this property, that is to say having a low surface tension and coming successively into contact with the gravure gravure cylinder and the textile support. It has a lower adhesiveness for the thermoadhesive material than that of the textile support.
- its surface is smooth, has neither vacuum nor roughness.
- It can be flexible, made from a glass fiber or aramid fiber structure covered with a layer of polytetrafluoroethylene (PTFE), or be made from silicone rubber.
- PTFE polytetrafluoroethylene
- It can also be rigid, for example consisting of a metal cylinder covered with a layer of polytetrafluoroethylene (PTFE).
- PTFE polytetrafluoroethylene
- the thermoplastic polymer 1 is melted. It may for example be a mixture based on polyamides softening between 133 ° C. and 145 ° C.
- the photogravure cylinder is brought to a relatively high temperature, for example from 230 to 250 ° C. At these temperatures, the thermoplastic polymer has a viscosity of between 14 and 33 MFI (Multi-Flow Index), which makes it possible to fill well and then empty the wells 20 of the gravure gravure cylinder and therefore to achieve a precise distribution of the fusible polymer.
- MFI Multi-Flow Index
- the temperature of the gravure cylinder 2 is equal to or greater from 0 to 80 ° C, preferably from 20 to 50 ° C than the melting temperature of the fusible polymer 1.
- the partially non-stick transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene (“Teflon"). It easily resists contact with the gravure cylinder 2 and the temperature of the latter is not likely to cause its alteration.
- Teflon silicone or polytetrafluoroethylene
- the transfer mat 5 then drives the points of fusible polymer 4 and puts them in contact with the textile support 3.
- thermoadhesive polymer dots 4 is controlled between the time when they are deposited by the gravure gravure cylinder 2 on the carpet 5 and that when they are brought into contact with the textile support 3. This control of the temperature of the polymer 4 is is naturally obtained; taking into account the ambient temperature and for a given temperature of the gravure cylinder, their temperature on arrival is a function of their transfer time, ie obtained by the use of means 13 during the transfer of points 4.
- the means 13 for controlling the temperature of points 4 may include a thermal enclosure or an air blower. Most often the temperature of points 4 will be slightly decreasing from rotogravure cylinder 2 until they come into contact with the textile support 3. At least their upper part, opposite their lower part or base, in contact with the carpet transfer must however remain in fusion to allow the adhesion of the points 4 on the textile support 3.
- the polymer dots 4 therefore have a higher viscosity than when they are deposited by the rotogravure cylinder 2, which makes it possible to avoid crossing the textile support 3 by these points 4 while allowing their adhesion to this support 3.
- the temperature of the base of points 4, in contact with the transfer belt 3, is generally slightly lower than that of the opposite upper side. This state of point 4 is advantageously exploited.
- the viscosity of the upper part of the point which comes into contact with the support allows adhesion and the higher viscosity of the base of point 4 limits its penetration into the support.
- the contact of the polymer with the textile support can be carried out when the polymer is at a temperature of approximately 150 to 160 ° C.
- the viscosity of the polymer is then approximately 25 to 20 MFI (Multi-Flow Index).
- Cooling the mat makes it possible for the base of the points, in contact with the latter, to be at a temperature below its upper part.
- the textile support 3 is not then brought to a high temperature and therefore a fragile support can be used without risk of deterioration.
- the process of the invention allows the use of numerous polymers commonly used in the field of textile coating.
- polymers commonly used in the field of textile coating.
- polyesters polyamides, polyolefins, polypropylenes, plasticized polyvinyl chlorides, thermoplastic polyurethanes, low density polyethylenes, high density polyethylenes ...
- thermoplastic polyurethanes low density polyethylenes
- high density polyethylenes high density polyethylenes
- the temperature of the cylinder must be higher than the melting temperature of the polymer so as to give it the necessary viscosity.
- the polymer does not have to withstand this temperature for a long time.
- the following temperatures, depending on the different polymers, are preferable: - Plasticized polyvinyl chloride ...
- the melting point of the polymer must allow the end use of the product: for example, this temperature must be lower than the temperature of the presses used by the manufacturers when they associate the fusible textile with the drapery. It must also be higher than the usual washing or dry cleaning temperature so that these operations do not affect the bonding.
- the melting temperature is preferably between 70 and 140 ° C.
- the softening temperature is essential both for the bondability of the polymer and for the determination of its wetting power. Bonding capacity allows textile bonding fusible on the drapery and its wetting power intervenes in the form taken by the drops of polymer when it rests on the transfer fabric.
- the polymer undergoes the effects of its environment and is degraded.
- the degradation temperature must not be exceeded.
- the viscosity of the polymer at the various temperatures to which it is subjected must be taken into account. - At the cylinder temperature, it must be sufficiently fluid to leave the cells and to be deposited on the transfer support. - During the transfer on the partially non-stick mat, it must be viscous enough not to spread and remain in the form of points. - When placed in contact with the textile support, the polymer must impregnate the surface fibers so as to ensure its attachment while remaining on the textile support surface itself.
- the polymer When the fusible textile is associated with the drapery, the polymer must be fluid enough to impregnate the fibers of the drapery, but also viscous enough to pass neither the drapery nor the textile support.
- the preferred polymers have a viscosity of between: . 10 and 150g / 10mn MFI (Multi-Flow Index) at 200 ° C, preferably between 20 and 100, . and 1 and 25g / 10mn MFI (Multi-Flow Index) at 130 ° C, preferably between 1 and 15.
- the physico-chemical properties are involved in the wettability of the polymer.
- the polymers used must be able to be deposited on the partially non-stick transfer support without losing the point shape and the dimensions given to them by the cylinder cavities.
- the apparatus of the invention allows the implementation of the method described above. It includes means 6 for supplying and heating the fusible polymer 1, a gravure cylinder in the hollow 2 rotating around an axis 7, a doctor blade 8 intended to collect the mass of adhesive possibly deposited in excess at the rotogravure cylinder surface 2.
- This transfer mat 5 has a surface which prevents the polymer which it receives from adhering to its surface even at the relatively high temperature at which this polymer can be brought into contact with the textile support 5. The fact that the carpet is non-stick must therefore allow that when the stitches 4 come into contact with the textile support 3 adheres more strongly to this support than to the transfer carpet.
- the surface of the transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene, for example known under the name "Teflon”.
- the apparatus preferably comprises means for cleaning the transfer mat 5 after the deposition of the points 4 on the textile support 3.
- the means comprise for example a brush 15 and prevent fibers possibly deposited by the textile support 3 on the carpet of trasnfert 5 are deposited on the rotogravure cylinder 2.
- the apparatus comprises means 9 for supplying the textile support, a cylinder 10 for bringing the textile support into contact with the dots 4 of fusible polymer and means 11 for receiving the fusible textile-based product.
- It includes a cooling zone 14 located between the contacting cylinder 10 and the receiving means 11.
- the non-stick mat 5 is closed on itself which allows it to operate in a closed loop and therefore to ensure continuous operation of the whole apparatus.
- the non-stick mat is carried by a cylinder 12.
- the distance between this textile support 3 and the non-stick mat 5 is precisely adjusted. It can be set absolutely or in other cases it is the pressure of application of the cylinder 10 for contacting against the non-stick mat 5 which is set. This or these adjustments make it possible to optimize the penetration of the textile support by the points 4 of heat-bonding polymer as well as the thickness of these points after their transfer to the support 3.
- the method and the apparatus of the invention therefore allow the implementation of a "HOT MELT” coating process in which the phases of carrying out the distribution of the heat-bonding polymer in points is dissociated from that of the deposit of these points on the textile support.

Description
La présente invention concerne un procédé de fabrication d'un produit thermocollant à base textile par enduction à chaud par points.The present invention relates to a process for manufacturing a textile-based fusible product by hot spot coating.
Les produits thermocollants à base textile sont maintenant couramment utilisés dans l'industrie vestimentaire et permettent par exemple la réalisation de doublures ou de tissus de renfort pouvant être scellés à chaud.Iron-on textile-based products are now commonly used in the clothing industry and allow, for example, the production of linings or reinforcing fabrics which can be heat sealed.
On connait déjà un certain nombre de procédés d'appareillages de fabrication de tels produits par enduction.There are already known a certain number of apparatuses for manufacturing such products by coating.
Une première catégorie de procédés, dits procédés "HOT MELT" consistent en l'application directe sur le support textile d'une masse fondue de polymère thermoplastique. Il est par exemple connu pour la mise en oeuvre de ce procédé de porter une masse de polymères à une température supérieure à sa température de fusion, de la répartir dans les cavités d'un cylindre d'héliogravure (gravé en creux), de râcler la surface de ce cylindre et de le mettre en contact avec le support textile sur lequel doivent être appliqués les points de polymère.A first category of processes, called "HOT MELT" processes, consist in the direct application to the textile support of a melt of thermoplastic polymer. It is for example known for the implementation of this process to bring a mass of polymers to a temperature higher than its melting temperature, to distribute it in the cavities of a gravure cylinder (debossed), to scrape the surface of this cylinder and put it in contact with the textile support on which the polymer dots must be applied.
Ces procédés présentent un certain nombre d'inconvénients qui les ont empêchés jusqu'à présent de se développer malgré les intérêts qu'ils présentent.These methods have a certain number of drawbacks which have hitherto prevented them from developing despite the advantages which they present.
En effet, cette méthode ne permet pas d'obtenir une enduction par points de qualité. L'action de la râcle ne permet pas d'éliminer totalement les traces de polymère sur les surfaces lisses du cylindre. Des résidus de polymère chaud subsistent sur ces surfaces et viennent en contact avec le support textile. Dans certains cas, le support textile, au contact du cylindre d'héliogravure, perd des fibres qui adhèrent au cylindre, concourrent à son encrassement et peuvent même écarter la râcle du cylindre qui produit une couche de polymère adhésif continue qui est alors déposée sur le support. La qualité du produit obtenu est faible et mal adaptée à son usage dans le domaine vestimentaire.Indeed, this method does not make it possible to obtain a coating by quality points. The action of the scraper does not completely eliminate traces of polymer on the smooth surfaces of the cylinder. Residues of hot polymer remain on these surfaces and come into contact with the textile support. In some cases, the textile support, in contact with the gravure cylinder, loses fibers which adhere to the cylinder, contribute to its fouling and can even remove the scraping of the cylinder which produces a layer of continuous adhesive polymer which is then deposited on the support. The quality of the product obtained is low and ill-suited to its use in the clothing sector.
Lors de la mise en oeuvre de cette méthode, la masse de polymère contenue dans les cavités, mise en contact avec le textile support adhère à celui-ci, ce qui contribue à vider la cavité et à déposer les points sur le support textile. Les textiles aérés, ou comportant des lacunes ou des vides ne permettent pas d'assurer une adhésion uniforme du polymère contenu dans toutes les cavités. Certaines d'entre elles ne sont alors pas convenablement vidées ce qui entraîne des défauts de l'enduction.During the implementation of this method, the mass of polymer contained in the cavities, brought into contact with the textile support adheres thereto, which contributes to empty the cavity and to deposit the points on the textile support. Aerated textiles, or with gaps or voids do not ensure uniform adhesion of the polymer contained in all the cavities. Some of them are then not properly emptied, which leads to coating defects.
On connait par ailleurs un procédé de fabrication de produits textiles thermoadhésifs dans lesquels l'adhésif est déposé sous forme de poudre ou de solution aqueuse, en points, sur le support. Après ce dépôt, l'ensemble est porté à une température élévée engendrant la mise en fusion du polymère et son adhésion sur le support.There is also known a process for manufacturing thermoadhesive textile products in which the adhesive is deposited in the form of powder or aqueous solution, in points, on the support. After this deposition, the assembly is brought to a high temperature causing the polymer to melt and adhere to the support.
Le brevet FR 2 586 717 décrit un procédé de cette dernière catégorie dans lequel on dépose d'abord des gouttes d'une dispersion de matière thermocollante sur un support de transfert anti-adhérent, on chauffe ensuite les gouttes sur le support de transfert puis on met en contact les gouttes d'adhésif avec le substrat textile.Patent FR 2 586 717 describes a process of this last category in which drops of a dispersion of fusible material are first deposited on a non-stick transfer support, the drops are then heated on the transfer support and then brings the drops of adhesive into contact with the textile substrate.
L'objet de la présente invention est un procédé et un appareillage qui présentent simultanément les avantages de la méthode d'enduction "HOT MELT", en autres d'éviter le broyage des polymères et les avantages de la méthode de transfert, en particulier de mettre en contact direct le textile avec le cylindre gravé et d'éviter de porter le support textile à une température élevée.The object of the present invention is a method and an apparatus which simultaneously present the advantages of the "HOT MELT" coating method, in addition to avoiding the grinding of polymers and the advantages of the transfer method, in particular of put the textile in direct contact with the engraved cylinder and avoid bringing the textile support to a high temperature.
Le procédé et l'appareillage de l'invention permettent de plus de réaliser une enduction par points présentant peu ou pas de défauts c'est-à-dire dont les points sont régulièrement répartis et le support n'est pas adhésif en dehors des points.The method and apparatus of the invention also make it possible to carry out a coating by points having little or no defects, that is to say those whose points are regularly distributed and the support is not adhesive outside the points .
A cet effet, il est proposé un procédé de fabrication d'un produit thermocollant à base textile par enduction à chaud par points du type dans lequel un polymère thermocollant est mis en fusion, un cylindre d'héliogravure gravé en creux chaud est garni avec ledit polymère thermoadhésif, la surface du cylindre râclée.To this end, a method of manufacturing a textile-based fusible product is proposed by hot spot coating of the type in which a fusible polymer is melted, a gravure cylinder engraved in a hot hollow is filled with said thermoadhesive polymer, the surface of the cylinder scraped.
Selon l'invention, le polymère thermocollant est déposé sous forme de points sur un tapis de transfert antiadhérent par le cylindre d'héliogravure et les points de polymère thermocollant sont ensuite mis en contact avec le support de manière à assurer leur transfert sur celui-ci.According to the invention, the fusible polymer is deposited in the form of dots on a non-stick transfer mat by the rotogravure cylinder and the dots of fusible polymer are then brought into contact with the support so as to ensure their transfer thereon. .
Il est également proposé un appareillage permettant la mise en oeuvre du procédé exposé plus haut, comportant des moyens d'alimentation et de chauffage du polymère thermocollant, un cylindre d'héliogravure gravé en creux, une râcle, des moyens de réception du produit thermocollant à base textile.It is also proposed an apparatus allowing the implementation of the process described above, comprising means for feeding and heating the fusible polymer, a gravure cylinder engraved in the hollow, a scraper, means for receiving the fusible product to textile base.
Selon l'invention, cet appareillage comporte un tapis antiadhérent assurant le transfert des points de polymère thermocollants du cylindre d'héliogravure vers le support textile et permettant le refroidissement partiel de ces points.According to the invention, this apparatus includes a non-stick mat ensuring the transfer of the fusible polymer dots from the rotogravure cylinder to the textile support and allowing these points to be partially cooled.
L'invention sera décrite plus en détail en référence au dessin dans lequel

Le procédé de l'invention permet la fabrication d'un produit thermocollant à base textile particulièrement destiné à l'industrie vestimentaire.The method of the invention allows the manufacture of a textile-based fusible product particularly intended for the clothing industry.
Ce type de produit comporte une base textile enduite par un polymère thermocollant.This type of product has a textile base coated with a heat-bonding polymer.
L'enduction par points permet d'obtenir un textile thermocollant de qualité qui lors de son utilisation finale après contrecollage sur un autre textile procure une souplesse et un toucher recherchés par les confectionneurs.The point coating makes it possible to obtain a quality fusible textile which, during its final use after laminating on another textile, provides the flexibility and touch sought after by manufacturers.
Une bonne enduction par points nécessite d'une part l'adhésion de chaque point de polymère sur le support et doit permettre d'éviter le dépôt d'adhésif en dehors de ces points.A good coating by points requires on the one hand the adhesion of each point of polymer on the support and must make it possible to avoid the deposit of adhesive outside these points.
Après sa fabrication, le produit thermocollant à base textile est stocké à la température ambiante et il est alors nécessaire que les différentes couches de ce produit en contact n'adhèrent pas les unes avec les autres.After its manufacture, the textile-based fusible product is stored at room temperature and it is then necessary that the different layers of this product in contact do not adhere to each other.
Le procédé de l'invention est du type "HOT MELT" c'est-à-dire qu'un polymère thermocollant 1 est mis en fusion puis utilisé pour remplir les cavités 20 d'un cylindre d'héliogravure 2 gravé en creux.The process of the invention is of the "HOT MELT" type, that is to say that a fusible polymer 1 is melted and then used to fill the
Jusqu'à présent dans ce type de procédé, le cylindre d'héliogravure 2 était directement mis en contact avec le support textile 3. La température du cylindre d'enduction 2 est alors un compromis. Elle doit être suffisamment élevée pour permettre de maintenir le polymère thermocollant à l'état fondu afin qu'il ne reste pas dans les cavités du cylindre et ne doit pas être trop élevée de manière à éviter la traversée du support textile ou même l'endommagement de celui-ci.Until now in this type of process, the gravure cylinder 2 was directly brought into contact with the textile support 3. The temperature of the coating cylinder 2 is then a compromise. It must be high enough to allow the fusible polymer to be kept in the molten state so that it does not remain in the cavities of the cylinder and must not be too high so as to avoid the crossing of the textile support or even damage. of it.
Selon l'invention, il a été montré que d'une manière surprenante il est possible de dissocier d'une part dans une première phase la répartition de l'adhésif en points, d'autre part dans une phase ultérieure le dépôt de ces points sur le support textile.According to the invention, it has been shown that in a surprising manner it is possible to dissociate on the one hand in a first phase the distribution of the adhesive in points, on the other hand in a later phase the deposition of these points on the textile support.
Cette dissociation entraîne simultanément la dissociation des contraintes exposées plus haut concernant la température du cylindre 2 et/ou du polymère thermocollant, répartissant ces contraintes dans les deux phases successives. La mise en oeuvre du procédé est alors grandement facilitée et permet d'obtenir des résultats satisfaisants.This dissociation simultaneously causes the dissociation of the stresses explained above concerning the temperature of the cylinder 2 and / or of the heat-bonding polymer, distributing these stresses in the two successive phases. The implementation of the method is then greatly facilitated and makes it possible to obtain satisfactory results.
Selon l'invention, le polymère thermocollant 1 est déposé sous forme de points 4 sur un tapis de transfert 5 partiellement anti-adhérent, les points de polymère thermocollant 4 sont ensuite mis en contact avec le support textile 3 de manière à assurer leur transfert sur celui-ci.According to the invention, the fusible polymer 1 is deposited in the form of dots 4 on a transfer mat 5 partially non-stick, the dots of fusible polymer 4 are then brought into contact with the textile support 3 so as to ensure their transfer to this one.
On appelle ici tapis de transfert 5 partiellement anti-adhérent toute surface ayant cette propriété c'est-à-dire présentant une faible tension de surface et entrant successivement en contact avec le cylindre d'héliogravure et le support textile. Il présente une adhésivité pour la matière thermoadhésive plus faible que celle du support textile.Here, the transfer mat 5 is partially non-stick any surface having this property, that is to say having a low surface tension and coming successively into contact with the gravure gravure cylinder and the textile support. It has a lower adhesiveness for the thermoadhesive material than that of the textile support.
De manière préférée, sa surface est lisse, ne présente ni vide ni aspérité.Preferably, its surface is smooth, has neither vacuum nor roughness.
Il peut être souple, réalisé à partir d'une structure de fibre de verre ou de fibre aramide recouverte d'une couche de polytétrafluoroéthylène (PTFE), ou être réalisé en caoutchouc siliconé.It can be flexible, made from a glass fiber or aramid fiber structure covered with a layer of polytetrafluoroethylene (PTFE), or be made from silicone rubber.
Il peut également être rigide, par exemple constitué d'un cylindre métallique recouvert d'une couche de polytétrafluoroéthylène (PTFE).It can also be rigid, for example consisting of a metal cylinder covered with a layer of polytetrafluoroethylene (PTFE).
Le polymère thermoplastique 1 est mis en fusion. Il peut s'agir par exemple d'un mélange à base de polyamides ramolissant entre 133°C et 145°C. Le cylindre d'héliogravure est porté à une température relativement élevée par exemple de 230 à 250°C. A ces températures le polymère thermoplastique a une viscosité comprise entre 14 à 33 MFI (Multi-Flow Index) ce qui permet de bien remplir puis ensuite de bien vider les alvéoles 20 du cylindre d'héliogravure et donc de réaliser une répartition précise du polymère thermocollant en points c'est-à-dire que la forme des points déposés sur le support de transfert antiadhésif correspond avec précision au dessin formé par les cavités du cylindre d'héliogravure ; la température du cylindre d'héliogravure 2 est égale ou supérieure de 0 à 80°C, de préférence de 20 à 50°C à la température de fusion du polymère thermocollant 1.The thermoplastic polymer 1 is melted. It may for example be a mixture based on polyamides softening between 133 ° C. and 145 ° C. The photogravure cylinder is brought to a relatively high temperature, for example from 230 to 250 ° C. At these temperatures, the thermoplastic polymer has a viscosity of between 14 and 33 MFI (Multi-Flow Index), which makes it possible to fill well and then empty the
Le tapis de transfert 5 partiellement antiadhérent est recouvert d'une couche de silicone ou de polytétrafluoroéthylène ("Teflon"). Il résiste sans difficulté à la mise en contact avec le cylindre d'héliogravure 2 et la température de ce dernier ne risque pas d'entraîner son altération.The partially non-stick transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene ("Teflon"). It easily resists contact with the gravure cylinder 2 and the temperature of the latter is not likely to cause its alteration.
Le tapis de transfert 5 entraîne alors les points de polymère thermocollant 4 et les met en contact avec le support textile 3.The transfer mat 5 then drives the points of fusible polymer 4 and puts them in contact with the textile support 3.
La température des points de polymère thermoadhésif 4 est contrôlée entre le moment où ils sont déposés par le cylindre d'héliogravure 2 sur le tapis 5 et celui où ils sont mis en contact avec le support textile 3. Ce contrôle de la température des points de polymère 4 est soit naturellement obtenue ; compte-tenu de la température ambiante et pour une température donnée du cylindre d'héliogravure, leur température à l'arrivée est fonction de leur temps de transfert, soit obtenue par la mise en oeuvre de moyens 13 pendant le transfert des points 4. Les moyens 13 permettant le contrôle de la température des points 4 peuvent comporter une enceinte thermique ou une soufflerie d'air. Le plus souvent la température des points 4 sera légèrement décroissante depuis de cylindre d'héliogravure 2 jusqu'à leur mise en contact avec le support textile 3. Au moins leur partie supérieure, opposée à leur partie inférieure ou base, en contact avec le tapis de transfert doit toutefois rester en fusion pour permettre l'adhésion des points 4 sur le support textile 3.The temperature of the thermoadhesive polymer dots 4 is controlled between the time when they are deposited by the gravure gravure cylinder 2 on the carpet 5 and that when they are brought into contact with the textile support 3. This control of the temperature of the polymer 4 is is naturally obtained; taking into account the ambient temperature and for a given temperature of the gravure cylinder, their temperature on arrival is a function of their transfer time, ie obtained by the use of
En général, lors de leur mise en contact avec le support textile 3, les points 4 de polymère présentent donc une viscosité plus élevée que lors de leur dépôt par le cylindre d'héliogravure 2 ce qui permet d'éviter la traversée du support textile 3 par ces points 4 tout en permettant leur adhésion sur ce support 3. La température de la base du points 4, en contact avec le tapis de transfert 3, est généralement légèrement inférieure à celle du côté supérieur opposé. Cet état du point 4 est avantageusement exploité. La viscosité de la partie supérieure du point qui vient en contact avec le support permet l'adhésion et la viscosité plus élevée de la base du point 4 limite sa pénétration dans le support.In general, when they are brought into contact with the textile support 3, the polymer dots 4 therefore have a higher viscosity than when they are deposited by the rotogravure cylinder 2, which makes it possible to avoid crossing the textile support 3 by these points 4 while allowing their adhesion to this support 3. The temperature of the base of points 4, in contact with the transfer belt 3, is generally slightly lower than that of the opposite upper side. This state of point 4 is advantageously exploited. The viscosity of the upper part of the point which comes into contact with the support allows adhesion and the higher viscosity of the base of point 4 limits its penetration into the support.
Lors de l'usage d'un mélange adhésif à base de polyamides, le contact du polymère avec le support textile peut être réalisé lorsque le polymère est à une température d'environ 150 à 160°C. La viscosité du polymère est alors d'environ 25 à 20 MFI (Multi-Flow Index).When using an adhesive mixture based on polyamides, the contact of the polymer with the textile support can be carried out when the polymer is at a temperature of approximately 150 to 160 ° C. The viscosity of the polymer is then approximately 25 to 20 MFI (Multi-Flow Index).
Un refroidissement du tapis permet d'obtenir que la base des points, en contact avec ce dernier soit à une température inférieure à sa partie supérieure.Cooling the mat makes it possible for the base of the points, in contact with the latter, to be at a temperature below its upper part.
Le support textile 3 n'est pas alors porté à une température élevée et donc un support fragile peut être utilisé sans risque de détérioration.The textile support 3 is not then brought to a high temperature and therefore a fragile support can be used without risk of deterioration.
Le procédé de l'invention permet l'utilisation de nombreux polymères couramment utilisés dans le domaine de l'enduction textile. A titre d'exemple, on citera les polyesters, les polyamides, les polyoléfines, les polypropylènes, les polychlorures de vinyl plastifiés, les polyuréthanes thermoplastiques, les polyéthylènes basse densité, les polyéthylènes haute densité... Ces polymères seront utilisés seuls ou le plus souvent mélangés à différents additifs, plastifiants, antioxydants etc... Lors de l'utilisation de ces polymères, la température du cylindre doit être supérieure à la température de fusion du polymère de manière à lui donner la viscosité nécessaire. Toutefois, le polymère n'a pas à supporter cette température pendant une longue durée. Les températures suivantes, en fonction des différents polymères sont préférables :
Le choix d'un polymère sera fait en prenant en considération ses propriétés thermiques, rhéologiques et physico-chimiques.The choice of a polymer will be made taking into consideration its thermal, rheological and physico-chemical properties.
La température de fusion du polymère doit permettre l'utilisation finale du produit : par exemple, cette température doit être inférieure à la température des presses utilisées par les confectionneurs lorsqu'ils associent le textile thermocollant à la draperie. Elle doit être également supérieure à la température habituelle de lavage ou de nettoyage à sec de telle sorte que ces opérations n'affectent pas le collage.The melting point of the polymer must allow the end use of the product: for example, this temperature must be lower than the temperature of the presses used by the manufacturers when they associate the fusible textile with the drapery. It must also be higher than the usual washing or dry cleaning temperature so that these operations do not affect the bonding.
La température de fusion est de préférence comprise entre 70 et 140°C.The melting temperature is preferably between 70 and 140 ° C.
La température de ramollissement est essentielle à la fois pour la capacité de collage du polymère et pour la détermination de son pouvoir mouillant. La capacité de collage permet le collage du textile thermocollant sur la draperie et son pouvoir mouillant intervient dans la forme prise par le gouttes de polymère lorsqu'elle repose sur le textile de transfert.The softening temperature is essential both for the bondability of the polymer and for the determination of its wetting power. Bonding capacity allows textile bonding fusible on the drapery and its wetting power intervenes in the form taken by the drops of polymer when it rests on the transfer fabric.
A haute température, le polymère subit les effets de son environnement et est dégradé. La température de dégradation ne doit pas être dépassée.At high temperature, the polymer undergoes the effects of its environment and is degraded. The degradation temperature must not be exceeded.
La viscosité du polymère aux différentes températures auxquelles il est soumis doit être prise en compte.
- A la température du cylindre il doit être suffisamment fluide pour sortir des alvéoles et pour être déposé sur le support de transfert.
- Au cours du transfert sur le tapis partiellement anti-adhérent, il doit être suffisamment visqueux pour ne pas s'étaler et rester sous forme de points.
- Lorsqu'il est placé en contact avec le support textile, le polymère doit imprégner les fibres de surface de manière à assurer son accrochage tout en restant à la surface support textile proprement dit.The viscosity of the polymer at the various temperatures to which it is subjected must be taken into account.
- At the cylinder temperature, it must be sufficiently fluid to leave the cells and to be deposited on the transfer support.
- During the transfer on the partially non-stick mat, it must be viscous enough not to spread and remain in the form of points.
- When placed in contact with the textile support, the polymer must impregnate the surface fibers so as to ensure its attachment while remaining on the textile support surface itself.
Lors de l'association du textile thermocollant à la draperie, le polymère doit être suffisamment fluide pour imprégner les fibres de la draperie mais également suffisamment visqueux pour ne traverser ni la draperie ni le support textile.When the fusible textile is associated with the drapery, the polymer must be fluid enough to impregnate the fibers of the drapery, but also viscous enough to pass neither the drapery nor the textile support.
Pour toutes ces raisons, les polymères préférés ont une viscosité comprise entre:
. 10 et 150g/10mn MFI (Multi-Flow Index) à 200°C, de préférence entre 20 et 100,
. et 1 et 25g/10mn MFI (Multi-Flow Index) à 130°C, de préférence comprise entre 1 et 15.For all these reasons, the preferred polymers have a viscosity of between:
. 10 and 150g / 10mn MFI (Multi-Flow Index) at 200 ° C, preferably between 20 and 100,
. and 1 and 25g / 10mn MFI (Multi-Flow Index) at 130 ° C, preferably between 1 and 15.
Les propriétés physico-chimiques interviennent dans la mouillabilité du polymère.The physico-chemical properties are involved in the wettability of the polymer.
Les polymères utilisés doivent pouvoir être déposés sur le support de transfert partiellement anti-adhérent sans perdre la forme ponctuelle et les dimensions qui leurs sont données par les cavités du cylindre.The polymers used must be able to be deposited on the partially non-stick transfer support without losing the point shape and the dimensions given to them by the cylinder cavities.
L'appareillage de l'invention permet la mise en oeuvre du procédé décrit plus haut. Il comporte des moyens 6 d'alimentation et de chauffage du polymère thermocollant 1, un cylindre d'héliogravure gravé en creux 2 tournant autour d'un axe 7, une râcle 8 destinée à recueillir la masse d'adhésif éventuellement déposée en excès à la surface du cylindre d'héliogravure 2.The apparatus of the invention allows the implementation of the method described above. It includes means 6 for supplying and heating the fusible polymer 1, a gravure cylinder in the hollow 2 rotating around an axis 7, a doctor blade 8 intended to collect the mass of adhesive possibly deposited in excess at the rotogravure cylinder surface 2.
Il comporte un tapis de transfert anti-adhérent 5. Ce tapis de transfert 5 comporte une surface qui évite l'adhesion sur sa surface du polymère qu'elle reçoit même à la température relativement élevé à laquelle ce polymère peut être mis en contact avec le support textile 5. Le fait que le tapis soit antiadhésif doit donc permettre que lors de la mise en contact des points 4 avec le support textile 3 adhère plus fortement à ce support qu'au tapis de transfert.It comprises a non-stick transfer mat 5. This transfer mat 5 has a surface which prevents the polymer which it receives from adhering to its surface even at the relatively high temperature at which this polymer can be brought into contact with the textile support 5. The fact that the carpet is non-stick must therefore allow that when the stitches 4 come into contact with the textile support 3 adheres more strongly to this support than to the transfer carpet.
La surface du tapis de transfert 5 est recouverte d'une couche de silicone ou de polytétrafluoroéthylène, par exemple connu sous la dénomination "Téflon".The surface of the transfer mat 5 is covered with a layer of silicone or polytetrafluoroethylene, for example known under the name "Teflon".
L'appareillage comporte de préférence des moyens de nettoyage du tapis de transfert 5 après le dépôt des points 4 sur le support textile 3. Les moyens comportent par exemple une brosse 15 et évitent que des fibres éventuellement déposées par le support textile 3 sur le tapis de trasnfert 5 viennent se déposer sur le cylindre d'héliogravure 2.The apparatus preferably comprises means for cleaning the transfer mat 5 after the deposition of the points 4 on the textile support 3. The means comprise for example a
L'appareillage comporte des moyens 9 d'alimentation du support textile, un cylindre 10 de mise en contact du support textile avec les points 4 de polymère thermocollant et des moyens de réception 11 du produit thermocollant à base textile.The apparatus comprises means 9 for supplying the textile support, a cylinder 10 for bringing the textile support into contact with the dots 4 of fusible polymer and means 11 for receiving the fusible textile-based product.
Il comporte une zone de refroidissement 14 située entre le cylindre 10 de mise en contact et les moyens de réception 11.It includes a cooling zone 14 located between the contacting cylinder 10 and the receiving means 11.
De manière préférentielle, le tapis antiadhérent 5 est refermé sur lui-même ce qui lui permet de fonctionner en boucle fermée et donc d'assurer un fonctionnement continu de l'ensemble de l'appareillage.Preferably, the non-stick mat 5 is closed on itself which allows it to operate in a closed loop and therefore to ensure continuous operation of the whole apparatus.
Dans un mode de réalisation particulièrement simple, le tapis antiadhérent est porté par un cylindre 12.In a particularly simple embodiment, the non-stick mat is carried by a cylinder 12.
Lors de la mise en contact du support textile 3 avec les points de polymère thermocollant 4, la distance entre ce support textile 3 et le tapis antiadhérent 5 est réglée avec précision. Il peut être réglé dans l'absolu ou dans d'autres cas c'est la pression d'application du cylindre 10 de mise en contact contre le tapis antiadhérent 5 qui est réglée. Ce ou ces réglages permettent d'optimiser le pénétration du support textile par les points 4 de polymère thermocollant ainsi que l'épaisseur de ces points après leur transfert sur le support 3.When the textile support 3 is brought into contact with the fusible polymer dots 4, the distance between this textile support 3 and the non-stick mat 5 is precisely adjusted. It can be set absolutely or in other cases it is the pressure of application of the cylinder 10 for contacting against the non-stick mat 5 which is set. This or these adjustments make it possible to optimize the penetration of the textile support by the points 4 of heat-bonding polymer as well as the thickness of these points after their transfer to the support 3.
Le procédé et l'appareillage de l'invention permettent donc la mise en oeuvre d'un procédé d'enduction "HOT MELT" dans lequel les phases de réalisation de la répartition du polymère thermocollant en points est dissociée de celle du dépôt de ces points sur le support textile.The method and the apparatus of the invention therefore allow the implementation of a "HOT MELT" coating process in which the phases of carrying out the distribution of the heat-bonding polymer in points is dissociated from that of the deposit of these points on the textile support.
