Description

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.

The invention will find its application in particular in the field of wet processing facilities such as for bleaching and dyeing a web continuously.

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.

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.

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.

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.

• - 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

• - on imprègne la matière textile d'une matière de traitement,
• - on diffuse la matière de traitement dans la matière textile et on maîtrise totalement, en fonction de la matière textile à traiter, et des matières de traitement appliquées, le temps de diffusion de la matière de traitement dans la matière textile en contrôlant, par un réglage continu, la longueur élémentaire du chemin parcouru dans le poste de travail correspondant,
• - 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:

• - the textile material is impregnated with a treatment material,
• - The treatment material is diffused into the textile material and the control time, depending on the textile material to be treated, and the treatment materials applied, is completely controlled by the diffusion time of the treatment material in the textile material, by controlling, by a continuous adjustment, the basic length of the path traveled in the corresponding work station,
• - the treatment material is fixed to the textile material,
• - the textile material is rinsed to remove the excess of non-fixed treatment material,
• - The tablecloth thus treated is dried.

According to the invention, the station for diffusing a treatment material into a textile material which will find its application in particular in an installation for continuous wet processing of textile material such as for example used for bleaching or dyeing a sheet of textile material, woven or nonwoven, authorizing in particular the implementation of the method of the invention, is characterized in that it comprises compensating means for controlling and adjusting the length of the path traveled in said station by the sheet of textile material being processed between the inlet and the outlet of the diffusion station in order to control the diffusion time.

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.

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.

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.

• - 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 (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.

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.

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.

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.

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 ).

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.

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. .

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.

• - 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).

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.

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.

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.

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.

• - 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.

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).

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.

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.

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).

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.

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.

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.

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).

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).

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.

Naturally, other implementations of the present invention could be envisaged without departing from the scope thereof.

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.
