Description

L'invention est relative à un procédé de traitement en continu par voie humide de matières textiles, tel que notamment utilisé pour le blanchiment ou la teinture d'une nappe de matière textile tissée ou non, ainsi qu'à un poste de diffusion d'une matière colorante dans une matière textile autorisant notamment la mise en oeuvre dudit procédé.The invention relates to a process for continuous wet processing of textile materials, such as in particular used for bleaching or dyeing a web of woven or non-woven textile material, as well as to a diffusion station for a coloring matter in a textile material allowing in particular the implementation of said process.

L'invention trouvera notamment son application dans le domaine des installations de traitement par voie humide telles que pour le blanchiment et la teinture d'une nappe en continu.The invention will find its application in particular in the field of wet processing facilities such as for bleaching and dyeing a web continuously.

Actuellement, il est connu deux modes de traitement essentiels par voie humide de nappes textiles, il s'agit soit du traitement en discontinue, foulard, séchoir, soit du traitement à la continue en un seul passage.Currently, two essential wet processing methods are known for textile tablecloths, this is either batch processing, scarf, drier, or continuous treatment in a single pass.

Dans le premier type de traitement, beaucoup plus traditionnel, on dispose la matière à traiter dans un appareil qui est rempli successivement de liquides qui peuvent être par exemple une solution de teinture, un liquide de fixation, un liquide de rinçage et quelquefois même par de la vapeur.In the first type of treatment, which is much more traditional, the material to be treated is placed in an apparatus which is successively filled with liquids which may for example be a dye solution, a fixing liquid, a rinsing liquid and sometimes even with steam.

Le deuxième type de traitement, dit à la continue, est moins développé que l'autre car il nécessite une installation de traitement plus élaborée et plus encombrante. Toutefois l'avantage de ce traitement est qu'il permet de travailler beaucoup plus vite et d'augmenter la production de matière traitée.The second type of treatment, said to be continuous, is less developed than the other because it requires a more elaborate and cumbersome treatment installation. However, the advantage of this treatment is that it makes it possible to work much faster and to increase the production of treated material.

Généralement, les installations de traitement à la continue sont constituées par une succession de postes de travail affectés chacun à une étape bien déterminée et on fait parcourir dans cette installation une nappe continue de matière textile selon un chemin de traitement bien défini dans l'installation. Ainsi, la nappe en continu subit les différentes étapes successivement entre l'entrée et la sortie de l'installation.Generally, the continuous processing installations consist of a succession of work stations each assigned to a well-defined stage and a continuous web of textile material is run through this installation according to a well-defined treatment path in the installation. Thus, the continuous web undergoes the various stages successively between the entry and the exit of the installation.

Il est connu, par exemple, des procédés de traitement en continu par voie humide de matières textiles, dans lesquels on fait subir successivement à la nappe parcourant l'installation :

  • - au moins une imprégnation de la matière textile d'une matière colorante, généralement suivie par une diffusion de la matière colorante dans la matière textile,
  • - une solubilisation des colorants avec un liquide véhiculeur du colorant suivie d'une fixation de la matière colorante à la matière textile par vaporisation, par exemple,
  • - un rinçage de la matière textile pour éliminer le surplus de la matière colorante non fixée suivi d'un séchage de la nappe ainsi traitée.
It is known, for example, continuous wet processing of textile materials, in which the web passing through the installation is subjected successively:
  • - at least one impregnation of the textile material with a coloring material, generally followed by a diffusion of the coloring material in the textile material,
  • a solubilization of the dyes with a dye-carrying liquid followed by fixing of the dyestuff to the textile material by spraying, for example,
  • a rinsing of the textile material to remove the excess of the non-fixed coloring material followed by drying of the sheet thus treated.

Dans ce procédé de teinture, on utilise généralement différents types de matière colorante de structures différentes et qui présentent des affinités particulières par rapport à la nature de la nappe. Toutefois, certaines règles d'application sont à respecter pour respecter leur efficacité. Actuellement, trois catégories essentielles de colorants sont utilisées et chacune de ces catégories nécessitent une mise en oeuvre propre pour obtenir une efficacité optimum.In this dyeing process, different types of coloring matter with different structures are generally used and which have particular affinities with respect to the nature of the web. However, certain application rules must be observed to respect their effectiveness. Currently, three essential categories of dyes are used and each of these categories requires its own implementation to obtain optimum efficiency.

Une première catégorie de colorants est généralement connue sous le nom "type cuve" qui se présente sous une forme insoluble pigmentaire. Lors de l'utilisation de ce type de colorant, on imprègne la matière textile du colorant par foulardage suivi d'une diffusion dans la fibre par un parcours à l'air de la nappe ce qui améliore l'aspect et la qualité de la teinture. Ensuite, la matière colorante est fixée par foulardage chimique et par vaporisation. Toutefois, après cette étape, il est important d'éviter un autre passage à l'air car il y a risque de modification de la structure du colorant, ce qui peut faire virer la nuance et influencer la solidité de la teinture. Ensuite, cette teinture est oxydée, rincée et séchée.A first category of dyes is generally known under the name "tank type" which is in an insoluble pigment form. When using this type of dye, the textile material is impregnated with the dye by padding followed by diffusion in the fiber by an air course of the sheet which improves the appearance and the quality of the dye. . Then, the coloring matter is fixed by chemical padding and by spraying. However, after this step, it is important to avoid another passage to air because there is a risk of modification of the structure of the dye, which can cause the shade to change and influence the solidity of the dye. Then, this dye is oxidized, rinsed and dried.

Un deuxième type de colorant est connu sous l'appellation "hydrone". Dans ce cas, on imprègne la matière textile du colorant par foulardage mais le colorant se trouve à l'état réduit avec de l'hydrosulfi- te de soude dans un bain. Alors, après ce foulardage, le passage à l'air pour diffuser la matière colorante dans la fibre textile est à éviter afin d'empêcher l'oxydation prématurée du colorant réduit, ce qui donnerait une nuance plus terne à la teinture. Ensuite, le colorant est fixé par vaporisage, qui sera avantageusement suivi d'un passage à l'air car une oxydation à l'air avant rinçage permettra d'obtenir un rendement du colorant supérieur. Ensuite, cette teinture est oxydée, rincée et séchée.A second type of dye is known by the name "hydrone". In this case, the textile material is impregnated with the dye by padding, but the dye is in the reduced state with sodium hydroxide in a bath. Then, after this padding, the passage to air to diffuse the coloring matter in the textile fiber is to be avoided in order to prevent the premature oxidation of the reduced dye, which would give a duller shade to the dye. Then, the dye is fixed by vaporization, which will advantageously be followed by a passage in air because an oxidation in air before rinsing will make it possible to obtain a higher yield of the dye. Then, this dye is oxidized, rinsed and dried.

Dans la troisième catégorie de colorants du type "indigosols" après l'imprégnation de la matière textile du colorant, il est indispensable de la diffuser par un passage à l'air avant la phase de fixation. Par ailleurs, un deuxième passage à l'air après cette phase de fixation à l'acide sulfurique est également indispensable pour le développement du colorant avant que la nappe soit rincée et séchée.In the third category of dyes of the "indigosol" type after the textile material of the dye has been impregnated, it is essential to diffuse it by passing it through the air before the fixing phase. Furthermore, a second passage in air after this fixing phase with sulfuric acid is also essential for the development of the dye before the sheet is rinsed and dried.

Pour permettre ces différentes mises en oeuvre de traitement selon les types de colorants, il est connu des installations de traitement en continu qui présentent successivement un poste d'alimentation en matière textile en nappe, suivi d'un poste d'imprégnation par foulardage de la matière colorante, suivi d'un poste de diffusion de la matière colorante par passage à l'air, suivi d'un poste de solubilisation du colorant par imprégnation de produits chimiques, suivi d'un poste de fixation du type vaporisateur, suivi d'un poste de traitement chimique à l'acide, suivi d'un deuxième poste de diffusion et développement du colorant par passage à l'air, suivi d'un poste de lavage et de rinçage, suivi d'un poste de séchage, suivi d'un poste d'emmagasinage de la matière ainsi traitée en continu.In order to allow these different processing implementations according to the types of dyes, continuous processing installations are known which successively have a textile material supply station in ply, followed by a padding impregnation station of the coloring matter, followed by a station for diffusing the coloring matter by passing it through the air, followed by a station for dissolving the dye by impregnating chemicals, followed by a spray-type fixing station, followed by a chemical acid treatment station, followed by a second station for the diffusion and development of the dye by passage through air, followed by a washing and rinsing station, followed by a drying station, followed by '' a station for storing the material thus treated continuously.

Dans une telle installation traditionnelle, selon les matières textiles à traiter et les différents colorants appliqués, il est nécessaire entre chaque changement de procédé d'opérer des arrêts de la ligne de traitement afin de modifier le parcours du chemin de la nappe en traitement dans l'installation (voir par exemple US-A 3 898 821). En effet, avec des colorants du type "cuve", seul le premier parcours à l'air de diffusion est utilisé, tandis que dans les cas de colorants de type "hydrone" ce premier passage à l'air sera évité et ce sera le second passage à l'air qui sera utilisé. Par contre, dans le cas de colorants du type "indigosols", les deux parcours à l'air de diffusion et de développement du colorant seront utilisés.In such a traditional installation, depending on the textile materials to be treated and the different dyes applied, it is necessary between each change of process to make stops on the treatment line in order to modify the path of the path of the tablecloth being treated in the 'installation (see for example US-A 3,898,821). In fact, with "tank" type dyes, only the first diffusion air route is used, while in the case of "hydrone" type dyes this first passage in air will be avoided and this will be the case. second pass to the air which will be used. However, in the case of colo rants of the "indigosols" type, the two air diffusion and dye development routes will be used.

Il est constamment remarqué que ces différentes modifications du chemin de la nappe dans l'installation nécessitent des manipulations importantes et des arrêts prolongés. De plus, ces différents changements de procédés créent des chutes de matières qui, selon la longueur de la ligne de traitement, ne sont pas négligeables.It is constantly noted that these various modifications to the path of the sheet in the installation require significant handling and prolonged stops. In addition, these different process changes create material scraps which, depending on the length of the processing line, are not negligible.

De plus, avec les postes de diffusion et de développement de la matière colorante dans la matière textile connus, généralement constitués par un ensemble de rouleaux de détours fixes parcourus par la nappe en traitement en zigzag, on travaille en tout ou rien et on ne maîtrise pas entièrement le temps de diffusion de la matière colorante en fonction de la matière textile et des colorants appliqués.In addition, with the stations for spreading and developing the coloring matter in the known textile material, generally constituted by a set of fixed detour rollers traversed by the sheet in zigzag treatment, we work in all or nothing and we do not control not entirely the diffusion time of the coloring matter depending on the textile material and the dyes applied.

Le but de la présente invention est de proposer un procédé de traitement en continu par voie humide de matières textiles, tel que notamment utilisé pour le blanchiment ou la teinture d'une nappe de matière textile tissée ou non, qui permette de maîtriser les phases de diffusion et de développement de la matière de traitement dans la matière textile en fonction de la matière à traiter et des matières de traitement appliquées tout en évitant les manipulations manuelles de changement de parcours précités entre deux types de traitement différents consécutifs.The object of the present invention is to provide a process for the continuous wet processing of textile materials, such as in particular used for bleaching or dyeing a web of woven or nonwoven textile material, which makes it possible to control the phases of diffusion and development of the treatment material in the textile material as a function of the material to be treated and the treatment materials applied while avoiding the manual manipulations of change of course mentioned above between two different types of consecutive treatment.

Un autre but de la présente invention est de proposer un procédé de traitement en continu par voie humide de matières textiles qui permette d'optimaliser l'efficacité des matières de traitement en contrôlant par un réglage continu le temps de diffusion de la matière de traitement dans la matière textile au cours dudit procédé de traitement.Another object of the present invention is to provide a process for the continuous wet treatment of textile materials which makes it possible to optimize the efficiency of the treatment materials by controlling by continuous adjustment the diffusion time of the treatment material in the textile material during said treatment process.

Un autre but de la présente invention est de proposer un poste de diffusion d'une matière colorante dans une matière textile qui permettra notamment de mettre en oeuvre le procédé de la présente invention et qui pourra être avantageusement intégré dans une installation de traitement en continu par voie humide afin d'éviter toutes les manipulations longues, manuelles, qui étaient jusqu'à ce jour obligatoires lors des changements de traitement. En effet, grâce aux postes de la présente invention, on pourra modifier le parcours du chemin de la nappe de matière textile à traiter par réglages extérieurs, en évitant les coupes de la nappe à traiter et les chutes de matières perdues.Another object of the present invention is to provide a station for diffusing a dyestuff into a textile material which will in particular allow the process of the present invention to be implemented and which may advantageously be integrated into a continuous treatment installation by wet to avoid all the long, manual manipulations, which until now were compulsory during treatment changes. Indeed, thanks to the stations of the present invention, it will be possible to modify the path of the path of the sheet of textile material to be treated by external adjustments, avoiding the cuts of the sheet to be treated and the falling of lost material.

Un autre but de la présente invention est de proposer un poste de diffusion d'une matière colorante dans une matière textile, qui autorise non pas un fonctionnement en tout ou rien mais au contraire un contrôle total du temps de diffusion, par réglage continu, entre une valeur pratiquement nulle et une valeur maximum prédéterminée.Another object of the present invention is to provide a station for diffusing a dyestuff into a textile material, which does not allow all-or-nothing operation but on the contrary a total control of the diffusion time, by continuous adjustment, between a practically zero value and a predetermined maximum value.

Un autre but de la présente invention est de proposer un procédé de traitement en continu par voie humide de matières textiles ainsi qu'un poste de diffusion de la matière de traitement dans la matière textile qui permettra de réduire substantiellement les coûts de production de la matière textile ainsi traitée.Another object of the present invention is to provide a process for the continuous wet processing of textile materials as well as a station for diffusing the treatment material into the textile material which will allow the production costs of the material to be substantially reduced. textile thus treated.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows, which is however only given for information and which is not intended to limit it.

Le procédé de traitement en continu par voie humide de matières textiles de l'invention, tel que notamment utilisé pour le blanchiment ou la teinture d'une nappe de matière textile tissée ou non, dans lequel procédé on fait parcourir une nappe continue de matière textile dans une installation comportant différents postes de travail successifs, ladite nappe définissant dans l'installation un chemin continu de traitement présentant une longueur donnée L entre l'entrée et la sortie de l'installation, chaque poste de travail respectif traitant une partie de la longueur L correspondant à la longueur élémentaire du chemin parcouru par la nappe dans le poste de travail considéré, est tel que :

  • - on fixe la matière de traitement à la matière textile,
  • - on rince la matière textile pour éliminer le surplus de matière de traitement non fixée,
  • - on sèche la nappe ainsi traitée.
The process for the continuous wet processing of textile materials of the invention, such as in particular used for bleaching or dyeing a sheet of woven or non-woven textile material, in which process a continuous sheet of textile material is passed through in an installation comprising different successive work stations, said ply defining in the installation a continuous treatment path having a given length L between the entry and the exit of the installation, each respective work station treating part of the length L corresponding to the elementary length of the path traversed by the tablecloth in the work station considered, is such that:

L'invention sera mieux comprise à la lecture de la description suivante accompagnée des dessins en annexe qui en font partie intégrante.

The invention will be better understood on reading the following description accompanied by the accompanying drawings which form an integral part thereof.
  • FIG. 1 schematically represents an installation for continuous wet processing of a textile material using stations for diffusing the dyestuff into the textile material according to an embodiment of the invention and authorizing the process for treating the present invention.

L'invention vise un procédé de traitement en continu par voie humide de matières textiles, tel que notamment utilisé pour le blanchiment ou la teinture d'une nappe de matière textile tissée ou non.The invention relates to a process for continuous wet processing of textile materials, such as no. much used for bleaching or dyeing a web of woven or non-woven textile material.

A titre d'exemple, la figure 1 représente une des installations de traitement qui pourrait être utilisée pour mettre en oeuvre le procédé de l'invention. Toutefois, cet exemple n'est pas limitatif et d'autres successions de postes de travail pourraient être envisagées.By way of example, FIG. 1 represents one of the processing installations which could be used to implement the method of the invention. However, this example is not limiting and other successions of work stations could be envisaged.

Tout d'abord, dans l'installation de traitement en continu (1) à partir d'un poste d'alimentation (2) apte à délivrer la matière textile à traiter (3) en continu, on fait parcourir une nappe (4) continue de matière textile. Entre l'entrée (5) et la sortie (6) de l'installation (1), la nappe (4) définit dans celle-ci un chemin continu de traitement présentant une longueur donnée L qui est formée par la somme des longueurs élémentaires du chemin parcouru par la nappe (4) dans chaque poste de travail successif.First of all, in the continuous treatment installation (1) from a feed station (2) capable of delivering the textile material to be treated (3) continuously, a web (4) is passed through. continuous textile material. Between the inlet (5) and the outlet (6) of the installation (1), the ply (4) defines therein a continuous processing path having a given length L which is formed by the sum of the elementary lengths of the path traveled by the tablecloth (4) in each successive work station.

Selon l'exemple représenté à la figure 1, l'installation comporte successivement les différents postes de travail suivants :

  • - un poste (7) d'imprégnation de la matière textile à traiter en matière colorante dans lequel on fait circuler la nappe (4) dans ladite matière colorante et ensuite on l'exprime par foulardage par exemple,
  • - un poste (8) de diffusion de la matière colorante dans la matière textile à traiter, objet de la présente invention et qui sera décrit ultérieurement,
  • - un poste (9) de solubilisation de la matière colorante dans lequel on imprègne la nappe (4) d'un produit chimique favorisant cette solubilisation,
  • - un poste (10) de fixation de la matière colorante dans la matière textile qui se présente notamment sous la forme d'un dispositif connu de vaporisage,
  • - un poste (11) de traitement chimique comportant pour certains traitements un bac de solution acide dans lequel la nappe (4) est immergée puis en sortie exprimée par foulardage par exemple,
  • - un deuxième poste (12) de diffusion et de développement de la matière colorante dans la matière textile objet de la présente invention,
  • - un poste (13) de rinçage réalisé selon une technique traditionnelle qui permet notamment, par plusieurs rinçages successifs, d'éliminer le surplus de matière colorante non fixée à la nappe (4),
  • - un poste (14) de séchage formé par exemple par une calandre chauffante de réalisation connue,
  • - un poste (15) d'accumulation de la nappe (4) traitée qui permet d'emmagasiner la nappe en vue de l'enrouler ultérieurement sur une bobine (16) par exemple et de changer de bobine sans arrêter la machine.
According to the example shown in FIG. 1, the installation successively comprises the following different work stations:
  • a station (7) for impregnating the textile material to be treated with dyestuff in which the sheet (4) is circulated in said dyestuff and then it is expressed by padding for example,
  • a station (8) for diffusing the coloring matter into the textile material to be treated, which is the subject of the present invention and which will be described later,
  • a station (9) for dissolving the coloring matter in which the sheet (4) is impregnated with a chemical promoting this solubilization,
  • a station (10) for fixing the coloring matter in the textile material, which is in particular in the form of a known spraying device,
  • a chemical treatment station (11) comprising, for certain treatments, a tank of acid solution in which the sheet (4) is immersed and then at the outlet expressed by padding for example,
  • a second station (12) for diffusing and developing the coloring matter in the textile material which is the subject of the present invention,
  • a rinsing station (13) produced according to a traditional technique which makes it possible in particular, by several successive rinses, to remove the excess of coloring matter not attached to the sheet (4),
  • a drying station (14) formed for example by a heating calender of known construction,
  • - A station (15) for accumulating the treated ply (4) which allows the tablecloth to be stored with a view to winding it subsequently on a reel (16) for example and to change reel without stopping the machine.

Avec ce type d'installation, on pourra notamment mettre en oeuvre des procédés de traitement en continu par voie humide de matières textiles qui utilisent pour la teinture les trois grandes catégories de colorants décrites précédemment, à savoir les colorants du type "cuve", "hydrone" et "indigosols". Toutefois, rappelons que chaque type de colorant nécessite des étapes spécifiques et un parcours de la nappe différent dans chaque cas.With this type of installation, it will be possible in particular to implement continuous wet processing methods for textile materials which use for dyeing the three main categories of dyes described above, namely dyes of the "vat" type, " hydrone "and" indigosols ". However, remember that each type of dye requires specific steps and a different course of the web in each case.

En effet, dans le cas d'un colorant du type "cuve", il est nécessaire d'effectuer un parcours à l'air juste après l'imprégnation de la nappe (4) de matière colorante dans le poste (7). Ce parcours à l'air sera avantageusement effectué dans le poste de diffusion (8) de la présente invention.Indeed, in the case of a dye of the "vat" type, it is necessary to carry out a course in air just after the impregnation of the sheet (4) of coloring material in the station (7). This air course will advantageously be carried out in the diffusion station (8) of the present invention.

Ainsi, on améliorera l'aspect et la qualité de la teinture par la bonne diffusion du colorant sous forme insoluble pigmentaire dans la fibre.Thus, the appearance and the quality of the dye will be improved by the good diffusion of the dye in pigment insoluble form in the fiber.

Par contre, pour éviter les risques de modification de la structure de colorant, et par suite pour éviter de faire virer la nuance et influencer la solidité de la teinture, on supprimera le second passage à l'air au niveau du poste de diffusion (12).On the other hand, to avoid the risks of modification of the dye structure, and consequently to avoid changing the shade and influencing the solidity of the dye, the second passage in the air at the diffusion station will be eliminated (12 ).

En ce qui concerne le cas du colorant "hydrone" foulardé à l'état réduit avec par exemple de l'hydro- sulfite de soude en solution, il sera avantageux d'éviter le premier passage à l'air dans le poste (8) mais par contre, autoriser le second passage à l'air dans le poste de diffusion (12) de l'invention.With regard to the case of the "hydrone" dye padded in the reduced state with, for example, sodium hydrosulphite in solution, it will be advantageous to avoid the first passage in air in the station (8) but on the other hand, authorize the second passage to air in the diffusion station (12) of the invention.

Ainsi, on obtiendra une bonne nuance et le second passage à l'air après le vaporisage au poste (10) permettra d'obtenir un rendement du colorant supérieur de 10 à 15 % car on lessiverait pendant le rinçage une partie du colorant non encore fixé.Thus, a good shade will be obtained and the second passage in air after spraying at the station (10) will make it possible to obtain a dye yield higher by 10 to 15% because part of the dye which is not yet fixed would be leached out during rinsing. .

Enfin, dans le cas du colorant du type "indigosols", il sera indispensable d'effectuer les deux passages à l'air au niveau du poste de diffusion (8) et du poste (12) tous deux prévus selon l'invention.Finally, in the case of the dye of the "indigosols" type, it will be essential to carry out the two passages in the air at the level of the diffusion station (8) and of the station (12) both provided according to the invention.

En effet, conformément à l'invention, on évite toute manipulation manuelle pour changer le parcours du chemin de la nappe (4) dans l'installation (1) et on réalise les différentes étapes du procédé suivantes :

  • - on imprègne la matière textile d'une matière colorante bien définie, par exemple au niveau du poste (7),
  • - on diffuse la matière colorante dans la matière textile, par exemple au niveau des postes de diffusion (8) et/ou (12), et on maîtrise totalement, en fonction de la matière textile à traiter et des matières colorantes appliquées, le temps de diffusion de la matière colorante dans la matière textile en contrôlant, par un réglage continu, la longueur élémentaire du chemin parcouru dans le poste de travail correspondant (8) et/ou (12),
  • - on fixe la matière colorante à la matière textile, notamment au niveau des postes (9), (10) et (11),
  • - on rince la matière textile pour éliminer le surplus de matière colorante non fixée, par exemple au niveau du poste (13),
  • - enfin, on sèche la nappe ainsi traitée en particulier au poste repéré (14).
Indeed, in accordance with the invention, any manual manipulation is avoided to change the path of the path of the sheet (4) in the installation (1) and the various stages of the following process are carried out:
  • - the textile material is impregnated with a well-defined coloring material, for example at the level of the station (7),
  • - the dyestuff is diffused into the textile material, for example at the diffusion stations (8) and / or (12), and time is completely controlled, depending on the textile material to be treated and the dyestuffs applied diffusion of the coloring matter into the textile material by controlling, by continuous adjustment, the elementary length of the path traveled in the corresponding work station (8) and / or (12),
  • the coloring matter is fixed to the textile material, in particular at the stations (9), (10) and (11),
  • the textile material is rinsed to remove the excess of non-fixed coloring material, for example at the station (13),
  • - Finally, the tablecloth thus treated is dried, in particular at the station identified (14).

Plus précisément, lors de l'étape de la diffusion qui s'effectue généralement par un passage à l'air de la nappe de matière textile imprégnée de la matière colorante, pour contrôler le temps de diffusion, on régie la longueur élémentaire du chemin parcouru dans le poste de diffusion (8) ou (12) par l'intermédiaire de moyens compensateurs (17) qui permettent de faire varier cette longueur d'une valeur sensiblement nulle, et donc ainsi d'éviter la phase de diffusion comme par exemple au poste (12) de la figure 1 vers une valeur préétablie maximum, et par suite d'autoriser un temps prédéterminé de diffusion, comme montré par exemple au poste (8) de la figure 1.More precisely, during the diffusion stage, which is generally carried out by passing the sheet of textile material impregnated with the dyestuff to air, to control the diffusion time, the elementary length of the path traveled is governed. in the broadcasting station (8) or (12) by means of compensating means (17) which make it possible to vary this length by a value substantially zero, and therefore thus to avoid the broadcasting phase as for example at station (12) of FIG. 1 towards a maximum preset value, and consequently of authorizing a predetermined broadcasting time, as shown for example at station (8) of FIG. 1.

Par ailleurs, selon l'invention, on modifie le trajet de la nappe (4) et par suite son chemin, en agissant, pendant le déroulement en continu de la nappe, sur lesdits moyens compensateurs (17), et toutefois simultanément, on asservit la vitesse de déroulement de la nappe (4) par l'intermédiaire de moyens (18) de contrôle de tension de la nappe afin d'augmenter la vitesse lorsqu'il faudra augmenter la longueur du parcours ou inversement diminuer la vitesse lorsqu'il faudra réduire cette longueur.Furthermore, according to the invention, the route is modified of the web (4) and consequently its path, by acting, during the continuous unwinding of the web, on said compensating means (17), and however simultaneously, the speed of unwinding of the web (4) is controlled by the 'Intermediate means (18) of tension control of the web in order to increase the speed when it is necessary to increase the length of the course or conversely decrease the speed when it is necessary to reduce this length.

Ces moyens de contrôle (18) seront constitués selon des techniques connues et notamment par un système de rouleau flottant (19) qui en fonction de son déplacement angulaire, donne une information sur la tension de la nappe (4) et permet l'asservissement de la vitesse pour que le rouleau flottant retrouve sa position normale. De même, il est à remarquer que les systèmes d'asservissement utilisés sont également des techniques connues de l'Homme de l'Art qui sortent du cadre de la présente invention.These control means (18) will be constituted by known techniques and in particular by a floating roller system (19) which, depending on its angular displacement, gives information on the tension of the ply (4) and allows the control of speed so that the floating roller returns to its normal position. Likewise, it should be noted that the servo systems used are also techniques known to those skilled in the art which are outside the scope of the present invention.

Une réalisation ainsi que le fonctionnement du poste de diffusion (8) ou (12) de matière colorante dans la matière textile selon la présente invention seront illustrés plus précisément aux figures 2 et 3. En effet, le poste de diffusion (8) ou (12) comporte essentiellement des moyens compensateurs (17) aptes à contrôler et à régler la longueur du chemin parcouru dans ledit poste (8) ou (12) par la nappe (4) de matière textile entre son entrée (20) et sa sortie (21). Ainsi, on maîtrise totalement le temps de diffusion de la matière colorante dans la matière textile y circulant.An embodiment and the operation of the diffusion station (8) or (12) of coloring material in the textile material according to the present invention will be illustrated more precisely in FIGS. 2 and 3. In fact, the diffusion station (8) or ( 12) essentially comprises compensating means (17) capable of controlling and regulating the length of the path traveled in said station (8) or (12) by the sheet (4) of textile material between its inlet (20) and its outlet ( 21). Thus, the diffusion time of the coloring matter in the textile material circulating therein is completely controlled.

Plus précisément, selon un mode de réalisation, le poste de diffusion (8) ou (12) comporte un bâti (22) interposé sur le chemin de la nappe (4) de matière textile en traitement et traversé par la nappe (4) de l'entrée (20) vers la sortie (21). Les moyens compensateurs (17) sont disposés dans ce bâti (22) et sont constitués essentiellement par :

  • - une première série de rouleaux de détours (23) fixes par rapport au bâti (22) et disposés d'un côté du chemin de la nappe (4),
  • - une deuxième série de rouleaux de détours (24), mobiles et disposés de sorte que les deux séries de rouleaux (23) et (24) puissent s'interpénétrer afin que la deuxième série (24) puisse être positionnée de part et d'autre du chemin de la nappe (4) entre deux positions extrêmes.
More specifically, according to one embodiment, the diffusion station (8) or (12) comprises a frame (22) interposed on the path of the ply (4) of textile material under treatment and crossed by the ply (4) of the inlet (20) to the outlet (21). The compensating means (17) are arranged in this frame (22) and consist essentially of:
  • - a first series of detour rollers (23) fixed relative to the frame (22) and arranged on one side of the web path (4),
  • - a second series of detour rollers (24), mobile and arranged so that the two series of rollers (23) and (24) can interpenetrate so that the second series (24) can be positioned on either side another of the path of the sheet (4) between two extreme positions.

Les figures 2 et 3 montrent un mode de réalisation de la présente invention, dans lequel la première série de rouleaux de détours (23) est formée de plusieurs rouleaux parallèles entre eux disposés horizontalement et parallèlement au-dessus du chemin de la nappe (4) et la deuxième série de rouleaux de détours (24) est formée de rouleaux, similaires aux premiers, parallèles entre eux, disposés horizontalement et en quinconce par rapport à la première série (23).Figures 2 and 3 show an embodiment of the present invention, in which the first series of detour rollers (23) is formed of several parallel rollers arranged horizontally and parallel to each other above the web path (4) and the second series of detour rollers (24) is formed of rollers, similar to the first, parallel to each other, arranged horizontally and staggered with respect to the first series (23).

Ainsi, la deuxième série de rouleaux (24) est apte à être déplacée verticalement entre deux positions extrêmes, l'une dite "position basse", repérée en (25) sur la figure 2, dans laquelle la deuxième série de rouleaux (24) est placée sous le chemin de la nappe (4), notamment sans aucun détour ni contact, pour permettre le chemin le plus court et d'autoriser un temps de diffusion pratiquement nul, l'autre dite "position haute" repérée par (26) à la figure 2, dans laquelle les rouleaux (24) sont placés au moins au-dessus du chemin de la nappe (4) pour permettre et forcer le cheminement de la nappe (4) à travers lesdites première et deuxième séries de rouleaux (23) et (24) et ainsi autoriser un temps de diffusion prédéterminé.Thus, the second series of rollers (24) is able to be moved vertically between two extreme positions, one called "low position", identified at (25) in FIG. 2, in which the second series of rollers (24) is placed under the path of the tablecloth (4), in particular without any detour or contact, to allow the shortest path and to allow a practically zero diffusion time, the other known as "high position" identified by (26) in FIG. 2, in which the rollers (24) are placed at least above the path of the ply (4) to allow and force the path of the ply (4) through said first and second series of rollers (23 ) and (24) and thus authorize a predetermined broadcast time.

Ainsi, par un réglage continu des moyens compensateurs (17), on pourra maîtriser le temps de diffusion d'une valeur nulle à une valeur prédéterminée, ceci par modification de la longueur du chemin parcouru dans le poste de diffusion. De plus, ces modifications seront commandées de l'extérieur de la machine et ne nécessiteront pas de manutention manuelles ni d'arrêt de la ligne de traitement comme cela était le cas avec les installations connues.Thus, by continuous adjustment of the compensating means (17), it will be possible to control the diffusion time from a zero value to a predetermined value, this by modifying the length of the path traveled in the diffusion station. In addition, these modifications will be controlled from outside the machine and will not require manual handling or stopping the processing line as was the case with known installations.

Dans un détail de réalisation, comme notamment illustrée la figure 3, la deuxième série de rouleaux (24) mobiles est maintenue dans un cadre (27) qui, d'une part, disposera lesdits deuxièmes rouleaux pour qu'il y ait enchevêtrement avec la première série de rouleaux (23) et qui, d'autre part, sera montée à coulissement et guidée dans le bâti (22) afin d'assurer un parfait parallèlisme entre les plans définis par les ensembles de rouleaux et celui du chemin de la nappe (4).In a detail of embodiment, as notably illustrated in FIG. 3, the second series of movable rollers (24) is held in a frame (27) which, on the one hand, will arrange said second rollers so that there is entanglement with the first series of rollers (23) and which, on the other hand, will be slidably mounted and guided in the frame (22) in order to ensure perfect parallelism between the planes defined by the sets of rollers and that of the web path (4).

En effet, ce parallèlisme est important pour éviter les plis dans la nappe et les défauts de traitement qui en découleraient. Par ailleurs, le cadre mobile (27) comportera des moyens de blocage afin de l'immobiliser selon le réglage souhaité et autoriser un fonctionnement stable.In fact, this parallelism is important in order to avoid folds in the sheet and the processing defects which would result therefrom. Furthermore, the movable frame (27) will include locking means in order to immobilize it according to the desired setting and allow stable operation.

Afin de faire varier la position du cadre (27) portant la série de rouleaux (24) entre la position basse (25) et la position haute (26), le poste de diffusion (8) ou (12) comportera des moyens d'élévation (28) qui autoriseront, notamment selon un réglage continu, les différentes positions souhaitées selon la nature de la nappe de textile à traiter et les colorants employés.In order to vary the position of the frame (27) carrying the series of rollers (24) between the low position (25) and the high position (26), the diffusion station (8) or (12) will include means for elevation (28) which will allow, in particular according to a continuous adjustment, the different desired positions according to the nature of the textile web to be treated and the dyes used.

Dans un mode de réalisation de la présente invention, on disposera d'un nombre de rouleaux de détours tel ainsi que d'une hauteur entre la position basse (25) et la position haute (26) telle qu'on puisse faire varier le temps de diffusion par exemple de 0 à quelques minutes, ce qui équivaut à un parcours sensiblement voisin de 15 à 60 mètres dans le poste de diffusion avec des vitesses de défilement de la nappe comprises entre 30 et 100 mètres par minute.In an embodiment of the present invention, there will be a number of detour rollers such as a height between the low position (25) and the high position (26) such that the time can be varied diffusion for example from 0 to a few minutes, which is equivalent to a route substantially close to 15 to 60 meters in the diffusion station with running speeds of the web between 30 and 100 meters per minute.

Ces moyens d'élévation pourront être constitués selon des techniques connues de l'Homme de l'Art et par exemple montrée aux figures 2 et 3 la transmission pourra s'effectuer par un ensemble de câbles ou de chaînes (29) et de poulies de renvoi (30) reliant le cadre au moyen moteur d'élévation (28).These elevation means may be constituted by techniques known to those skilled in the art and for example shown in Figures 2 and 3 the transmission may be carried out by a set of cables or chains (29) and pulleys return (30) connecting the frame to the lifting motor means (28).

Les moyens d'élévation pourront notamment être constitués par des systèmes à vérin pneumatique ou hydraulique, qui présenteront des moyens de pression réglables sur la nappe (4), asservis à la vitesse de défilement de la nappe pendant la modification de la hauteur de la deuxième série de rouleaux (24).The lifting means may in particular be constituted by pneumatic or hydraulic cylinder systems, which will have adjustable pressure means on the web (4), controlled by the running speed of the web during the modification of the height of the second series of rollers (24).

Dans l'exemple représenté un vérin de chaque côté permettra d'effectuer ces déplacements, les deux ensembles de vérins étant synchronisés entre eux selon des techniques connues de l'Homme de l'Art pour maintenir le parallèlisme requis.In the example shown, a jack on each side will allow these movements to be made, the two sets of cylinders being synchronized with each other according to techniques known to those skilled in the art to maintain the required parallelism.

Naturellement, d'autres mises en oeuvre de la présente invention pourraient être envisagées sans pour autant sortir du cadre de celle-ci.Naturally, other implementations of the present invention could be envisaged without departing from the scope thereof.

Par ailleurs, le nombre de postes de diffusion utilisé dans une installation sera conditionné essentiellement par la nature de la matière à traiter, la nature des colorants ainsi que leur mode d'application.In addition, the number of diffusion stations used in an installation will be conditioned essentially by the nature of the material to be treated, the nature of the dyes as well as their mode of application.
