Abstract

The present invention relates to a method of printing on polyamide and/or polyester fabrics by using the offset process, characterised in that the following various means are employed in combination: - the use, in the photogravure of a 175 screen colour selection, of the process known as "sub-colour contraction" which will enable us to obtain a tone with an ink charge of less than 150% for the same definition; - the use of a printing machine in which the fabric is picked up and conveyed continuously through the entire machine; - printing in a single pass on a single machine; - the use of printing liquids, ink or water, containing drying accelerators; - and, after printing, the coating of the printed surface of the fabric by the mechanical bonding of the varnish (polyvinyl chloride resin) to the textile.

Description

La présente invention concerne un procédé d'impression sur des tissus en polyamide et/ou en polyester.The present invention relates to a printing process on polyamide and / or polyester fabrics.

Il est connu qu'il est difficile d'utiliser le procédé classique de l'offset pour réaliser l'impression des tissus en polyamide et/ou en polyester.It is known that it is difficult to use the conventional offset process for printing polyamide and / or polyester fabrics.

Cette difficulté provient notamment de ce que :
- lesdits tissus ne présentent pas, en général, une rigi­dité suffisante pour pouvoir être aisément manipulés et positionnés dans plusieurs machines offset ;
- lesdits tissus ne sont pas aussi absorbants - vis-à-vis des liquides utilisés, tels que les encres et l'eau - que le papier.
This difficulty stems in particular from the fact that:
- Said fabrics do not generally have sufficient rigidity to be able to be easily handled and positioned in several offset machines;
- said fabrics are not as absorbent - vis-à-vis the liquids used, such as inks and water - as paper.

Il convient donc, lorsque l'on souhaite réaliser l'impression des tissus en polyamide et/ou polyester à l'aide de procédés de type offset, d'adapter convenablement les techniques de l'offset. C'est là l'objet de la présente invention.When it is desired to print polyamide and / or polyester fabrics using offset-type processes, it is therefore appropriate to adapt offset techniques. This is the object of the present invention.

On notera immédiatement que le mot impression utilisé ici doit être pris dans son sens le plus général ; on vise en effet à imprimer sur le tissu des lignes, des dessins, des lettres, des couleurs, etc.It will be immediately noted that the word impression used here must be taken in its most general sense; the aim is in fact to print lines, drawings, letters, colors, etc. on the fabric.

Les diverses caractéristiques du procédé selon l'invention, caractéristiques qui doivent être utilisées en combi­naison, sont les suivantes :
- utilisation, en photogravure d'une sélection couleur de trame 175, du procédé connu sous le nom de ''retrait de sous-­couleur" qui nous permettra d'obtenir un ton d'une charge d'encre inférieure à 150 % avec la même définition ;
- utilisation d'une machine d'impression, dans lequel le tissu est pris et conduit en continu à travers toute la machine ;
- impression en une seule passe sur une seule machine ;
- utilisation de liquides d'impression - encre ou eau - contenant des accélérateurs de séchage ;
- et, après impression, enduction de la surface imprimée du tissu à l'aide de l'accrochage du vernis (résine de polychlorure de vinyle) sur le textile mécaniquement.
The various characteristics of the process according to the invention, characteristics which must be used in combination, are the following:
- use, in photogravure of a 175 screen color selection, of the process known as "under-color removal" which will allow us to obtain a tone with an ink charge of less than 150% with the same definition;
- use of a printing machine, in which the fabric is taken and driven continuously through the whole machine;
- printing in a single pass on a single machine;
- use of printing liquids - ink or water - containing drying accelerators;
- and, after printing, coating the printed surface of the fabric using the bonding of the varnish (polyvinyl chloride resin) on the textile mechanically.

On utilise le procédé dit de "retrait sous-couleur" parce que ce procédé permet à la charge d'encre déposée sur le tissu d'être relativement peu importante. Cette charge d'encre est infé­rieure de 150 % dans l'échelle de Brunner, alors qu'elle est normalement de 300 à 350 % et plus dans le cas des papiers. Une charge d'encre trop grande ne permettrait pas un séchage suffi­samment rapide et ne permettrait pas ultérieurement le maintien dans le temps de l'impression même après dépôt du vernis.The so-called "sub-color removal" process is used because this process allows the ink charge deposited on the fabric to be relatively small. This ink load is 150% lower in the Brunner scale, whereas it is normally 300 to 350% and more in the case of paper. Too large an ink charge would not allow sufficiently rapid drying and would not subsequently allow printing to be maintained over time even after the varnish has been deposited.

De plus, le tissu à imprimer doit, après avoir été soigneusement coupé, équerré et débarrassé de toutes ses aspérités, être maintenu et conduit pendant tout son passage dans la machine d'impression. On utilisera donc des machines offset possédant cette possibilité, ces machines ayant un système de transport de feuille particulier à marge ou à succion et non à nappes horizontales qui ne permettraient pas un transport fiable, comme le sont par exemple les machines de type SPEEDMASTER (de chez HEIDELBERG).In addition, the fabric to be printed must, after having been carefully cut, squared and stripped of all its roughness, be maintained and driven throughout its passage through the printing machine. We will therefore use offset machines with this possibility, these machines having a particular sheet transport system with margin or suction and not with horizontal layers which would not allow a reliable transport, as are for example machines of the SPEEDMASTER type (of at HEIDELBERG).

Il convient également, comme mentionné, d'éviter d'avoir à effectuer le travail d'impression dans plusieurs machines successives, car cela nécessite un positionnement et un repérage du tissu, à chaque changement de machines, qui est difficile à faire. On choisira donc, selon le but cherché, une machine deux ou quatre couleurs, dans laquelle l'impression sera entièrement faite en une seule passe.It is also advisable, as mentioned, to avoid having to carry out the printing job in several successive machines, because this requires positioning and marking of the fabric, with each change of machines, which is difficult to do. We will therefore choose, depending on the goal, a two or four color machine, in which the printing will be done entirely in one pass.

Enfin, comme indiqué, les liquides d'impression (à savoir l'eau et les encres) devront être conditionnés pour avoir une durée de séchage aussi courte que possible ; pour cela, on utilisera des produits connus pour posséder cette propriété vis-à-vis desdits liquides, comme des accélérateurs de séchage pour les encres ou des siccatifs pour l'eau.Finally, as indicated, the printing liquids (ie water and inks) should be conditioned to have as short a drying time as possible; for this, products known to have this property will be used with respect to said liquids, such as drying accelerators for inks or siccatives for water.

Le vernis utilisé est du type des vernis employés en sérigraphie ; il a pour but de bloquer l'encre et de parfaire la résistance au soleil, aux agents atmosphériques et à l'usure. Les caractéristiques de ces vernis sont connues ; on notera cependant que l'on choisira de préférence un vernis dont la viscosité est comprise entre environ 15 et 20 poises et présente une rétraction faible de l'ordre de 1 pour 1000 ; on déposera généralement une épaisseur de 8 à 12 microns dudit vernis.The varnish used is of the type of varnishes used in screen printing; its purpose is to block the ink and to improve resistance to the sun, atmospheric agents and wear. The characteristics of these varnishes are known; note however that one will preferably choose a varnish whose viscosity is between about 15 and 20 poises and has a low shrinkage of the order of 1 per 1000; generally deposit a thickness of 8 to 12 microns of said varnish.

Comme moyen accessoire, on notera qu'il y a intérêt à utiliser un procédé de sélection de couleurs (des encres) de type connu (en utilisant par exemple un scanner), mais en employant une trame relativement fine qui est de préférence la trame présentant 175 lignes de points au pouce.As an accessory means, it will be noted that it is advantageous to use a method of selecting colors (inks) of known type (by using for example a scanner), but by using a relatively fine screen which is preferably the screen having 175 lines of dots per inch.

L'invention est illustrée par l'exemple non limitatif suivant.The invention is illustrated by the following nonlimiting example.

A l'aide d'un document couleur ou d'une diapositive représentant le motif à exécuter sur le polyamide, nous faisons une sélection de Trame 175 (SCANNER DAINIPPON - SCREEN LASER) en retrait de sous-couleur, c'est-à-dire une diminution de valeur de pourcentage dans les films du bleu, rouge et jaune de 15 à 25 %, ce qui nous donnera une charge d'encre maximale qui ne dépassera pas 150 % de la surface à imprimer pour le composition d'un ton avec l'ensemble des couleurs employées en superposition.Using a color document or a slide representing the pattern to be executed on the polyamide, we make a selection of Weft 175 (SCANNER DAINIPPON - SCREEN LASER) indented in sub-color, that is to say say a decrease in percentage value in films of blue, red and yellow from 15 to 25%, which will give us a maximum ink charge which will not exceed 150% of the surface to be printed for the composition of a tone with all the colors used in superposition.

La photogravure étant faite, nous effectuons nos reports, c'est-à-dire 4 plaques (1 plaque par couleur), à l'aide de notre machine 4 couleurs, type SPEEDMASTER de marque HEIDELBERG (R.F.A.), machine à imprimer ayant un type particulier de système de trans­port de la feuille (TISSU) ; au préalable, notre massicotier a coupé et équerré le TISSU NYLON pour éviter d'avoir de graves incidents au passage en machine. Le format de la feuille est de 65 cm sur 92 cm. Les encres utilisées sur machines sont des encres traditionnelles, dites grasses, mais avec une addition d'un agent accélérateur de séchage et d'un siccatif dans l'eau de mouillage.The photogravure being made, we carry out our reports, that is to say 4 plates (1 plate per color), using our 4 color machine, type SPEEDMASTER brand HEIDELBERG (RFA), printing machine having a special type of sheet transport system (FABRIC); beforehand, our cutter cut and squared the NYLON FABRIC to avoid having serious incidents when passing through the machine. The format of the sheet is 65 cm by 92 cm. The inks used on machines are traditional inks, called fatty inks, but with the addition of a drying accelerator and a siccative in the fountain water.

L'impression étant terminée, pour fixer l'encre sur la matière, on dépose sur celle-ci un film d'un vernis à base de matière plastique qui durcisse au séchage en s'accrochant dans la matière plastique de la feuille et qui soit insoluble dans l'eau (le vernis utilisé : uréthanne - acrylate).The printing being finished, to fix the ink on the material, a film of a plastic-based varnish is deposited thereon, which hardens on drying by clinging to the plastic of the sheet and which is insoluble in water (the varnish used: urethane - acrylate).

On fait sécher le vernis dans un four équipé de lampes à ULTRA-VIOLETS, l'épaisseur de la couche de vernis est d'environ 10 microns.The varnish is dried in an oven equipped with ULTRA-VIOLET lamps, the thickness of the varnish layer is approximately 10 microns.
