Description

> «> "

La présente invention est relative à un procédé destiné à améliorer les propriétés physiques ' de produits non-tissés, en particulier d’une laine de verre, en vue d’améliorer ses propriétés d’imprima-bilité et l’invention s’étend aux produits obtenus par ce procédé.The present invention relates to a process intended to improve the physical properties of nonwoven products, in particular glass wool, with a view to improving its printability properties and the invention extends to products obtained by this process.

5 De tels produits peuvent dans certains cas être utilisés tels quels mais constituent en général des produits semi-finis servant de dossiers destinés à la réalisation de produits de recouvrement de murs, mais surtout de sols.5 Such products can in certain cases be used as such but generally constitute semi-finished products serving as files intended for the production of wall covering products, but especially of floors.

**

On sait que l’utilisation de l’amiante est de plus en plus réduite 10 actuellement pour la réalisation de dossiers pour des produits servant au revêtement des sols.It is known that the use of asbestos is currently being reduced more and more 10 for the production of files for products used for flooring.

On a donc cherché à remplacer l’amiante par différentes matières parmi lesquelles la laine de verre revêt actuellement une importance croissante.We have therefore sought to replace asbestos with various materials, among which glass wool is currently becoming increasingly important.

15 ‘ Il est courant d’imprégner un voile non-tissé, généralement un voile de fibres de verre par un plastisol en procédant à une double imprègne tion, une application se réalisant au verso pour boucher les pores, l’autre application étant réalisée au recto afin d’obtenir une surface parfaitement lisse et non poreuse qui permet d’éviter un effet d’étalement des encres 20 au cours d’une impression héliographique ultérieure. Cette ”double imprégnation" est généralement réalisée en deux passes successives.15 'It is common to impregnate a non-woven veil, generally a veil of glass fibers with a plastisol by carrying out a double impregnation, an application being carried out on the back to plug the pores, the other application being carried out front in order to obtain a perfectly smooth and non-porous surface which makes it possible to avoid a spreading effect of the inks 20 during a subsequent heliographic printing. This "double impregnation" is generally carried out in two successive passes.

Après cette "double imprégnation" qui se limite en fait à une enduction recto-verso, le produit est gélifié dans un four où on fait circuler, généralement en continu, le voile traité.After this "double impregnation" which is in fact limited to a double-sided coating, the product is gelled in an oven where the treated veil is circulated, generally continuously.

25 ' Ce procédé présente cependant certains inconvénients résultant du fait que Γ enduction sur deux faces, sans que soit réalisée une imprégnation v à coeur, emprisonne souvent dans le voile de non-tissé une certaine quantité d’air. Lors d’une cuisson ultérieure, il se produit fréquemment que l’air emprisonné se dilate sous l’effet de la chaleur, en formant des irrégulari- 30 tés de surface (pustules) qui rendent le produit impropre à la vente.25 'This process however has certain drawbacks resulting from the fact that Γ coating on two sides, without an impregnation v being carried out through the heart, often traps a certain amount of air in the fleece. During subsequent cooking, it frequently occurs that the trapped air expands under the effect of heat, forming surface irregularities (pustules) which make the product unfit for sale.

L’utilisation d’un four de gélification entraîne également un encombrement important des lignes de production, par suite de la longueur relativement importante du four et une vitesse de production peu élevée.The use of a gelling oven also results in a large footprint of the production lines, due to the relatively long length of the oven and a low production speed.

La présente invention vise en conséquence à porter remède aux inconvénients indiqués des procédés de l’état de la technique- 1 La Demanderesse a trouvé qu’il est possible d’obtenir une impré- 11 gnation à coeur d’un non-tissé par un procédé simple et rapide consistant * 2 face du non-tissé un plastisol présentant une viscosité pratiquement newtonienne et d'une valeur comprise entre 4 et 30 poises, et en provoquant le passage du non-tissé imprégné sur un cylindre chauffé à une température de 130 à 180°C, la face imprégnée du non-tissé· étant présentée vers le 3 cylindre.The present invention therefore aims to remedy the indicated drawbacks of the processes of the state of the art. The Applicant has found that it is possible to obtain an impregnation in the core of a nonwoven with a simple and fast process consisting * 2 side of the nonwoven a plastisol having a viscosity practically Newtonian and of a value between 4 and 30 poises, and causing the passage of the impregnated nonwoven on a cylinder heated to a temperature of 130 at 180 ° C, the impregnated side of the nonwoven · being presented towards the 3 cylinder.

Ladite face imprégnée est celle qui sera soumise ultérieurement à l'impression héliographique.Said impregnated face is that which will subsequently be subjected to heliographic printing.

Dans les conditions indiquées, on observe trois résultats dont la conjonction est totalement inattendue. En effet le plastisol 10 est totalement gélifié sans que le voile imprégné ne colle au cylindre, ce qui confère donc un bon fini de surface, on obtient une imprégnation à coeur du voile et l'envers est prégélifié et sec en quittant le cylindre prégélificateur.Under the conditions indicated, three results are observed, the conjunction of which is completely unexpected. In fact, plastisol 10 is completely gelled without the impregnated veil sticking to the cylinder, which therefore gives a good surface finish, an impregnation is obtained at the heart of the veil and the reverse side is pregelified and dry when leaving the pregelifier cylinder.

Après refroidissement, le produit obtenu subit une inqprégnation héliographique et constitue un produit semi-fini servant de sous-couche 13 pour la fabrication notamment de revêtements de sols et autres.After cooling, the product obtained undergoes a heliographic impregnation and constitutes a semi-finished product serving as a sub-layer 13 for the manufacture in particular of floor coverings and the like.

Le choix de la température précise pour le traitement se réalise en fonction de la vitesse de passage du produit sur le cylindre et en fonction du diamètre du cylindre. Le praticien choisira aisément en fonctio de l'installation dont il dispose, qui impose largement la vitesse de 20 défilement du voile et du diamètre du cylindre qu’il peut utiliser, la température adéquate par une série d'essais de réglage de l'installation, en observant qu'il doit éviter un collage du voile imprégné au cylindre et obtenir une imprégnation à coeur du voile.The choice of the precise temperature for the treatment is carried out according to the speed of passage of the product on the cylinder and according to the diameter of the cylinder. The practitioner will easily choose according to the installation at his disposal, which largely dictates the speed of travel of the veil and the diameter of the cylinder that he can use, the appropriate temperature by a series of tests for adjusting the installation. , observing that it must avoid sticking of the impregnated veil to the cylinder and obtain an impregnation at the heart of the veil.

La température pour une vitesse de passage de 8 à ^fO m/mn et un 25 diamètre du cylindre de l'ordre de 2m, avec un enveloppement du cylindre sur 75 % de son périmètre est de préférence de l'ordre de 130°C.The temperature for a passage speed of 8 to 10 fm / min and a diameter of the cylinder of the order of 2 m, with a wrapping of the cylinder over 75% of its perimeter is preferably of the order of 130 ° C. .

Dans des installations courantes, une température inférieure à la limite de 130°C ne permet pas d'obtenir une imprégnation à coeur adéquate, tandis qu'une température supérieure à la limite indiquée entraîne une 30 fluidité trop marquée, ce qui rend difficile une application adéquate du plastisol et donne des finis de surface ne convenant pas pour une impression héliographique ultérieure.In common installations, a temperature below the limit of 130 ° C. does not make it possible to obtain an adequate impregnation to the core, while a temperature above the limit indicated results in too marked a fluidity, which makes application difficult. adequate plastisol and provides surface finishes not suitable for subsequent gravure printing.

Le plastisol est un plastisol tel qu'il est généralement utilisé en enduction. Dans la plage de viscosité indiquée de k à 30 33 poises, on accorde la préférence à une viscosité de 6 à 15 poises et tout J particulièrement de l'ordre de 8 poises- Cette plage de viscosité peut être obtenue facilement au départ de préparations de plastisol du commerce ün η-hiΊ î «airh dns riïiiiants olassinues ou. le cas échéant, des épaississants.Plastisol is a plastisol as it is generally used in coating. In the viscosity range indicated from k to 30 poises, preference is given to a viscosity of 6 to 15 poises and especially J of the order of 8 poises. This viscosity range can be easily obtained from preparations of commercial plastisol ün η-hiΊ î "airh dns riïiiiants olassinues ou. if necessary, thickeners.

3 :3:

Le comportement rhéologique du plastisol utilisé doit être pratiquement newtonien mais un comportement légèrement pseudo-plastique est cependant admissible.The rheological behavior of the plastisol used must be practically Newtonian but a slightly pseudo-plastic behavior is however admissible.

Le passage sur le cylindre chauffé s'effectue avantageusement 5 en pressant simultanément la face non-imprégnée par un cylindre presseur garni d'un revêtement élastique tel que du caoutchouc.The passage over the heated cylinder is advantageously carried out by simultaneously pressing the non-impregnated face by a pressure cylinder provided with an elastic coating such as rubber.

On observe que dans ces conditions, sur la face du voile qui est imprégnée, en amont du point de contact avec le cylindre chauffé, se crée un bourrelet de plastisol qui a pour résultat de former un film régulier 10 de plastisol. On obtient de cette manière l'état de surface adéquat souhait similaire à celui obtenu dans les films calandres. Cependant, et ceci constitue un autre effet inattendu, on n'observe pas d'épaississement du plastisol dans ce bourrelet, qui rendrait l'application impossible.It is observed that under these conditions, on the face of the veil which is impregnated, upstream of the point of contact with the heated cylinder, a bead of plastisol is created which has the result of forming a regular film 10 of plastisol. In this way, the desired surface finish is obtained, similar to that obtained in calendered films. However, and this constitutes another unexpected effect, no thickening of the plastisol is observed in this bead, which would make application impossible.

La réalisation pratique du procédé peut se faire selon le mode 15 opératoire qui sera décrit ci-après en référence à une représentation schématique d'une installation convenant pour la mise en pratique de l'invention.The practical implementation of the process can be carried out according to the operating mode which will be described below with reference to a schematic representation of an installation suitable for practicing the invention.

Dans la figure unique annexée, on a représenté une installation convenant pour l'imprégnation d'un dossier composite constitué d'une sous-20 couche quelconque sur lequel est appliqué un voile de fibre de verre.In the single appended figure, there is shown an installation suitable for the impregnation of a composite backing made up of any underlayment to which a fiberglass veil is applied.

Dans la figure, un dossier composite 1 composé d'une sous-couche et d'un voile de verre est amené vers un cylindre applicateur 3 tournant dans un réservoir contenant un plastisol. La face formée par le voile de verre est en contact avec le cylindre applicateur et reçoit une 25 dose adéquate du plastisol.In the figure, a composite file 1 composed of an underlay and a glass veil is brought to an applicator cylinder 3 rotating in a tank containing a plastisol. The face formed by the glass veil is in contact with the applicator cylinder and receives an adequate dose of the plastisol.

Après cette application, on réalise sur un cylindre de renvoi et à l'aide d'un dispositif à lame d'air 6, une égalisation du film de plastisol appliqué. L'excès de plastisol est recueilli par une tôle 7 ·> solidaire du réservoir h et est renvoyé dans ce réservoir.After this application, an equalization of the applied plastisol film is carried out on an idler cylinder and using an air knife device 6. The excess plastisol is collected by a sheet 7 ·> secured to the tank h and is returned to this tank.

1 30 Le dossier composite ainsi imprégné circule ensuite vers un : cylindre chauffé 10 sur lequel il s'applique en passant entre celui-ci et un cylindre presseur 12 à revêtement de caoutchouc. Un dispositif classique assure une application régulière et à pression réglable, du cylindre presseur 12 sur le cylindre 10.The composite folder thus impregnated then circulates towards a: heated cylinder 10 on which it is applied by passing between it and a rubber-coated pressure cylinder 12. A conventional device ensures regular application and at adjustable pressure, of the pressing cylinder 12 on the cylinder 10.

33 La face du dossier ayant reçu l'enduction de plastisol est, ainsi J qu'il est indiqué, appliquée sur le cylindre en couvrant environ 73 à 80 % de son périmètre, le cylindre 10 étant chauffé par exemple à une tempéra- _______ *i_ π t___A»___ ΙίΤ/'λΟ/·*33 The side of the backrest having received the plastisol coating is, as indicated, applied to the cylinder covering approximately 73 to 80% of its perimeter, the cylinder 10 being heated for example to a temperature _______ * i_ π t ___ A »___ ΙίΤ / 'λΟ / · *
