Installation pour 1e traitement dune bande continue de produit textile. Installation for the treatment of a continuous strip of textile product.

La presente Invention a pour objet une Installation pour 1e traitement dune bande continue de produit textile, permettant no tamment de produire en une operation conti nue des lots contröles de maueres teintes ou traitees chimiquement -d'une graude unifor mite. L'inventeur a remarque que pour obte nir une grande uniformite, il est preferable d'appliquer tout d'abord les couleurs ou produits chimiques ä la mauere et ensuite de realiser soit -dans la meme aperation, soit par une operation separee, un d6velo@ppe ment ou une teinture dans 1'installation conforme ä 1'invention de fagon ä fixer con venablement les matiere@s colorantes ä la ma, tiere formant la bande. L'installation selon 1'invention est particulierement indiquee pour la teinture continue aveo des, colorants de cuve, mais, elle peut aussi eire employee avantageusement pour 1e traitement a;vec un des produits des autres -roupes de colorants ou avec des produits chimiques qui n6ces sitent un d6veloippement, une reduction ou une fixation additionnels pour presenter leur stabilite maximum. Les colorants de cuve, sous leur forme de p b,-ments, ont peu ou pas d'affinite et, de ce fait, ils peuvent etre appliques tres uniformement sous cette forme sur la matiäre ä teindre, mais ils necessitent un traitement de reduetion ulte rieur, de fagon ä co qu'ils soient fixes conve nablement ä la mauere teinte pour obtenir leur stabilite, The subject of the present invention is an installation for the treatment of a continuous web of textile product, making it possible in particular to produce in a continuous operation controlled batches of mauers dyed or chemically treated - of a graude uniformity. The inventor has noticed that to obtain a great uniformity, it is preferable to first apply the colors or chemical products to the maureen and then to carry out either - in the same aperation, or by a separate operation, a development Adding or dyeing in the installation according to the invention so as to suitably fix the dyestuffs to the material forming the strip. The installation according to the invention is particularly suitable for continuous dyeing with vat dyes, but it can also be advantageously employed for the treatment with one of the products of other dye groups or with chemicals which these require additional expansion, reduction, or fixation to exhibit their maximum stability. Vat dyes, in their powder form, have little or no affinity and therefore can be applied very evenly in this form to the material to be dyed, but they require an ultimate reduction treatment. so as to co ensure that they are suitably fastened to the wrong shade to obtain their stability,

These baffles 21 are suspended, by means of cleats 22, ä, from the upper part of the tank, in wells 23 located between -los partitions and the side walls of the tank. These ohicanes extend across the width of the tank. They are slightly thinner than the width of the wells in which they are suspended and thus form narrow passages for the tax tile heath and the liquid which surrounds it.

L'extremite inferieure des ohicanes prä sente deug suppörts 24 dans lesquels tourne un rouleau 25. Ce rouleau a, un diametre legerement plus grand quo 1'epaisseur de la chieane. Les diametres des rouleaux 20 et 25 sont tels que, la Lande 16 soit guidee ä, tra vers les, couloirs. etroits constituos entre les chicanes et les cloisons adjaaentes du bac. Des cylindres superposes siont montes Sur des Supports 26 prevus Sur lese cötes du ba;c. Une premiexe paire de cylindres 27, 28 est situee au-dessus de 1a cloison -9; Aparant 1e.

La fig. 3 represente la mise en marche de Finstallation. La quantite requise de solution chimique ayant ete versee dans les puits 23, une bande de produit textile est introduite entre les paires, de eylindres 27, 28; 29, 30; 31 et 32. fig. 3 represents the start-up of the installation. The required quantity of chemical solution having been poured into the wells 23, a strip of textile product is introduced between the pairs of cylinders 27, 28; 29, 30; 31 and 32.

Les chicanes sont mises en placa s,oit simultanement, soit successivement dann leurs fpuits respectifs p'our que la bande de textile soit obligee de parcourir ehacun des puits du bac, suivant un chemin sinueux, comme representA ä 1a fig. 1. The baffles are put in place either simultaneously or successively in their respective wells so that the strip of textile is forced to travel through each of the wells of the tank, following a winding path, as shown in FIG. 1.

La bande sortant du puits situe en avant de la clozson 9 est suppiortee par la pre miere paire de cylindres avaut de pas,ser dans; 1e groupe de puits situ@ entre les cloi sons. 9 et 12. De la meme maniere, la bande de produit textile passe entre la seconde paire de cylindres avant de tpiais,ser dans 1e groupe de puits situe entre la cloison 12 et la troisieme paire de cylindres. The strip coming out of the well located in front of the clozson 9 is supported by the first pair of cylinders before step, ser in; 1st group of wells located between the partitions. 9 and 12. In the same way, the web of textile product passes between the second pair of cylinders before entering the first group of wells located between the partition 12 and the third pair of cylinders.

Le niveau du liquide de traite.ment qui passe sur 1e rouleau superieur 20 place au dessus de la cloison 7 est detei#mine par 1e debit d'introduction de liquide dans Finstal latiou en 17. La vitesse - d'eeoailement du liquide est determinee ä 1'entree@ 17 et la ha.uteur de la pellicule de liquide au-dessus du rouleaux 20 est determinee ä 1a sortie 18. The level of the treatment liquid which passes over the upper roller 20 placed above the partition 7 is determined by the flow rate at which liquid is introduced into the installation at 17. The speed of the liquid is determined at the inlet 17 and the height of the liquid film above the rollers 20 is determined at the outlet 18.

Lorsque la. bande de produit textile est entrainee dans Finstallation, elle entraine avec elle une tres mince pellicule de liquide de traitement qui Fentoure et qui n'est modi fiee que par 1'action d'essorage des cylindres sniperposes. Du liquide de traitement frais est introduit par Fentonnoir 15 en meme temps que 1e liquide epuise est 6vacue par 1e trop-plein 18. When the. strip of textile product is drawn into the installation, it carries with it a very thin film of treatment liquid which surrounds it and which is only modified by the wringing action of the superimposed cylinders. Fresh process liquid is introduced through funnel 15 at the same time as spent liquid is discharged through overflow 18.

La surface du liquide de traitement ex pos6e ä fair est limitee ä la surface com prise entre les chicanes et au-dessus des cloi zons. Cette surface est tres faible comparee ä, celle du produit textile .ä traiter. Ainsi 1e contact entre 1e liquide @de traitement et Fair est reduit, ce qui est tres important lorsque ce liquide dpit Gtre protege de 1'oxydation. The surface of the treatment liquid exposed to the air is limited to the surface comprised between the baffles and above the partitions. This surface is very small compared to that of the textile product to be treated. Thus the contact between the treatment liquid and the air is reduced, which is very important when this liquid has been protected from oxidation.

Dans certains cas, des solutions tincto riales separees peuvent etre jutroduites suc aessivement. Par exemple, une teinture qui agit lentement peut eire intreduite avec la bande de produit textile et etre suivie dune teinture agis@sant plus rapidement, introduite, dans 1e pnzits situe entre 1a cloison 9 et la cloison 10. Ces deux teintures auront termine leur reacti.on lorsque la bande de produit textile .sortira du dernier puits. In some cases, separate dye solutions may be added aggressively. For example, a slow-acting dye can be introduced with the strip of textile product and be followed by a faster-acting dye introduced into the pnzits between the partition 9 and the partition 10. These two dyes will have completed their reaction. .on when the strip of textile product will come out of the last well.

Certaines reactions peuvent necessiter 1e deplacement du produit textile dann Finstal lation en sens oppose ä 1'ecoulement .du reactif liquide. Ceci peut etre facilement realise dann Finstallation telle que decrite. Some reactions may require movement of the textile product in the installation in the opposite direction to the flow of the liquid reactant. This can easily be done in the installation as described.

Au lieu de chauffer 1e bain d'eau du bac au moyen du oerpentin 5, an peut utiliser egalement de la vapeur, du .gaz -ou des ele ments electriques. De tels moyens de chauf fage pe.uvent egalement etre appliques -aux chicanes amovibles. Instead of heating the water bath of the tank by means of the heater 5, one can also use steam, gas or electrical elements. Such heating means pe.uvent also be applied -to the removable baffles.

Le trajet en ehicane paraouru spar 1e pro duit textile donne une .surfa,ce maximum de eonta.et avec 1a solution et une exposition minimum de liquide ä fair. Ceci diminue les quantites requises de produits chimiques reducteurs tels que 1'hydrosulfite de sodium. The mechanical path through the textile product gives maximum surface area with solution and minimum liquid exposure. This decreases the required amounts of reducing chemicals such as sodium hydrosulfite.

Pour employer Finstallation de Finven tion au mieux, il faut tenir compte des temps de reaction determines par 1a nature de la bande de textile e@t du ou des. liquides de traitement. To use the installation of the invention as best as possible, it is necessary to take into account the reaction times determined by the nature of the textile strip and of the or of. treatment liquids.
