This can happen in particular in the presence of metal ions which act as catalysts and are located in the material web. The decomposition of hydrogen peroxide produces oxygen, water and heat.

If the individual applicators are provided with controllable valves, as can also be provided according to the invention, a controlled loading of the textile goods to be treated can be achieved depending on their position and width. An adaptation to the respective task can be achieved in that the distance between the applicator or applicators and the web of the goods is adjustable.
  • the applicator or applicators are preferably arranged and aligned in such a way that the product is loaded with the liquor when it rests on one of the rollers.

  • a particular embodiment of the invention deals with the problem that the chemical liquor sprayed from the nozzle to the goods does not reach the textile goods completely, rather a part remains as a chemical mist in the free vapor space. Even if the applicators, as provided according to the invention, are connected upstream of the damper in a separate application container, with the application container being continuously steam-rinsed, the chemical mist can still adhere to the walls and the ceiling of the application container.

Description

Die Erfindung betrifft eine Vorrichtung zum Behandeln einer Textilware nach dem Oberbegriff des Patentanspruchs 1
Bei bekannten Vorrichtungen zum Bleichen, Waschen, Färben, Abkochen, Entschlichten, Mercerisieren oder dgl. einer Textilware wird diese durch in dem Behälter ausgebildete Bäder geführt, in denen die Textilware mit der Flotte getränkt wird. Um eine ausreichende Reaktionszeit der Flotte zu ermöglichen, ist - in Durchlaufrichtung gesehen - hinter den Bädern eine Vielzahl von oberen und unteren Walzen vorgesehen, über welche die Textilware geführt wird, bevor sie den Behälter verläßt.
The invention relates to a device for treating a textile product according to the preamble of patent claim 1
In known devices for bleaching, washing, dyeing, boiling, desizing, mercerizing or the like. A textile product is passed through baths formed in the container, in which the textile product is soaked with the liquor. In order to enable the fleet to react sufficiently, there is a large number of upper and lower rollers behind the baths, as seen in the direction of flow provided over which the textile goods are guided before they leave the container.

Eine kürzere Verweildauer der Textilware in dem Behälter ergibt sich, wenn, wie dies bei der gattungsgemäßen Vorrichtung (ES-PS 545 681) der Fall ist, die Textilware in dem Behälter mit einem Aerosol der Flotte beaufschlagt und alsdann einer Dampfbehandlung bekannter Art unterworfen wird, welche die aufgebrachte Flotte auf die Textilware einwirken läßt. Dabei wird das als "Flotte" bezeichnete Behandlungsmedium (regelmäßig wässrige Lösungen oder Dispersionen geeigneter Chemikalien) als Aerosol unter hohem Druck auf die zu behandelnde Textilware aufgebracht, wobei die Bildung des Aerosols, welches unter hohem (Dampf-)Druck auf die Textilware aufgebracht wird, durch die Zuführung thermischer Energie bewirkt wird.A shorter dwell time of the textile goods in the container results if, as is the case with the generic device (ES-PS 545 681), the textile goods in the container are subjected to an aerosol of the liquor and are then subjected to a steam treatment of a known type. which allows the applied fleet to act on the textile goods. The treatment medium referred to as "liquor" (regularly aqueous solutions or dispersions of suitable chemicals) is applied as an aerosol to the textile goods to be treated under high pressure, the formation of the aerosol which is applied to the textile goods under high (steam) pressure, is brought about by the supply of thermal energy.

Bei der gattungsgemäßen Vorrichtung ist der Dämpfer in den die Applikatoren aufnehmenden Behälter integriert, wobei notwendigerweise das Volumen des Behälter verhältnismäßig groß ist. Da der Siedepunkt z.B. einer Wasserstoffperoxidlösung oberhalb des Siedepunkts von reinem Wasser liegt und beheizte Deckenplatten oder dgl., die heißer als 100° C sind, zu einem Verdunsten des Wassers und somit zu einer Aufkonzentration z.B. des Peroxids in dem Behälter führen, besteht bei der bekannten Vorrichtung Verpuffungsgefahr, weil oberhalb einer bestimmten Grenzkonzentration und Grenztemperatur das Peroxid dazu neigt, sich spontan zu zersetzen. Dies kann insbesondere bei dem Vorhandensein von als Katalysatoren wirkenden, in der Warenbahn befindlichen Metallionen geschehen. Bei der Zersetzung des Wasserstoffperoxids entstehen Sauerstoff, Wasser und Wärme. Die Wärme führt dazu, daß das Wasser verdampft. Die Volumenvergrößerung durch die Zersetzung beträgt dabei bis zu einem Vier tausendfachen des ursprünglichen Volumens. Die Verpuffungsgefahr ist somit erheblich.In the generic device, the damper is integrated in the container receiving the applicators, the volume of the container necessarily being relatively large. Since the boiling point of, for example, a hydrogen peroxide solution is above the boiling point of pure water and heated ceiling panels or the like, which are hotter than 100 ° C., lead to evaporation of the water and thus to a concentration of, for example, the peroxide in the container, the known one exists Device Risk of deflagration, because above a certain limit concentration and limit temperature the peroxide tends to decompose spontaneously. This can happen in particular in the presence of metal ions which act as catalysts and are located in the material web. The decomposition of hydrogen peroxide produces oxygen, water and heat. The heat causes the water to evaporate. The volume increase due to the decomposition is up to a four a thousand times the original volume. The risk of deflagration is therefore considerable.

Aus GB 20 78 268 A ist eine Behandlungsvorrichtung mit einem Applikationsbehälter bekannt, in welchem kalte Flotte mittels Düsen auf die Textilbahn aufgebracht wird. Dies geschieht in einer Atmosphäre aus unter Überdruck stehender Luft mit normaler Temperatur. Zur Dampfbehandlung ist ein getrennter Dämpfer mit einer Atmosphäre aus unter Überdruck stehendem Dampf mit einer Temperatur von über 100°C vorgesehen. Der Eingang des Dämpfers ist über eine Schleuse mit dem Ausgang des Applikationsbehälters verbunden. Dem Applikationsbehälter wird am Eingang Luft unter Druck zugeführt, während an der Schleuse eine ständige Luftabfuhr erfolgt. Hierdurch wird bewirkt, daß eine Trennung zwischen Luft- und Dampfatmosphäre erfolgt, ohne daß die Textilbahn gepreßt werden muß.GB 20 78 268 A discloses a treatment device with an application container in which cold liquor is applied to the textile web by means of nozzles. This is done in an atmosphere of pressurized air at normal temperature. For steam treatment, a separate damper with an atmosphere of steam under pressure at a temperature of over 100 ° C is provided. The input of the damper is connected to the output of the application container via a lock. Air is supplied to the application container under pressure at the inlet, while the air is constantly evacuated at the lock. This has the effect that there is a separation between air and steam atmosphere without the textile web having to be pressed.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art zu schaffen, bei denen eine derartige Verpuffungsgefahr nicht gegeben ist.The invention has for its object to provide a device of the generic type in which there is no such risk of deflagration.

Erfindungsgemäß wird diese Aufgabe vorrichtungsmäßig durch die im Kennzeichen des Patentanspruches 1 aufgeführten Merkmale gelöst. Besonders bevorzugte Ausführungsformen der Vorrichtung nach der Erfindung sind Gegenstand der Unteransprüche 2 bis 38.According to the invention, this object is achieved in device terms by the features listed in the characterizing part of patent claim 1. Particularly preferred embodiments of the device according to the invention are the subject of subclaims 2 to 38.

Der Erfindung liegt die Erkenntnis zugrunde, daß es gelingt, der bei der gattungsgemäßen Vorrichtung vorhandenen Verpuffungsgefahr durch Aufkonzentration z.B. von Peroxiden dadurch entgegenzuwirken, daß der Behälter, in welchem die Applikatoren angeordnet sind, von dem eigentlichen Dämpfer räumlich getrennt ist, so daß das Volumen des Raumes, der die Applikatoren aufnimmt, relativ gering sein kann. Ferner wird erfindungsgemäß der die Applikatoren aufnehmende Behälter ständig dampfgespült, so daß die Chemikalien, insbesondere das Peroxid, welche nicht auf das Gewebe gelangt sind bzw. welches nicht auf das Gewebe gelangt ist und deren/dessen Aufkonzentration droht, ständig abgeführt werden bzw. wird. Eine Verpuffung ist somit zuverlässig ausgeschlossen.The invention is based on the knowledge that it is possible to reduce the risk of deflagration in the generic device by concentration, e.g. counteracting peroxides by separating the container in which the applicators are located from the actual damper, so that the volume of the space accommodating the applicators can be relatively small. Furthermore, according to the invention, the container holding the applicators is continuously steam-rinsed, so that the chemicals, in particular the peroxide, which have not got onto the tissue or which have not got onto the tissue and whose concentration is imminent, are or are continuously removed. A deflagration is therefore reliably excluded.

Ist die Einrichtung zum Zuführen thermischer Energie, die zum einen die Bildung des Aerosols bewirkt und zum anderen für den ausreichenden Aufbringdruck sorgt, zum Einbringen von unter Überdruck stehendem Wasser bzw. Dampf ausgebildet, wie dies erfindungsgemäß vorgesehen sein kann, so bewirkt die hohe thermische Energie des unter Überdruck stehenden Wassers bzw. des überspannten Dampfes ein Verdampfen der Flotte unter Bildung eines Aerosols. Wenn der Applikator durch wenigstens zwei auf denselben Punkt ausgerichtete Einstoffdüsen gebildet ist, wie dies erfindungsgemäß weiterhin vorgesehen sein kann, erfolgt die Zuführung von thermischer Energie zu der Flotte (und damit die Aktivierung) erst unmittelbar auf der Textilware. Bei einer solchen Ausbildung wird die Flotte durch die eine Düse und der Dampf durch die andere Düse auf das Material aufgebracht, wobei die thermische und die kinetische Energie des Dampfes ein Eindringen der Flotte in die Ware und deren Aktivierung bewirkt.If the device for supplying thermal energy, which on the one hand causes the formation of the aerosol and on the other hand ensures the sufficient application pressure, is designed for introducing water or steam under excess pressure, As can be provided according to the invention, the high thermal energy of the pressurized water or steam causes the liquor to evaporate to form an aerosol. If the applicator is formed by at least two single-substance nozzles aligned at the same point, as can also be provided according to the invention, thermal energy is only supplied to the liquor (and thus the activation) directly on the textile goods. With such a design, the liquor is applied to the material through one nozzle and the steam through the other nozzle, the thermal and kinetic energy of the steam causing the liquor to penetrate the goods and activate them.

Eine gleichmäßige Beaufschlagung der Textilware mit dem Aerosol der Flotte läßt sich insbesondere dann erzielen, wenn, wie erfindungsgemäß vorgeschlagen wird, eine Mehrzahl von im wesentlichen quer zur Transportrichtung der Ware nebeneinander angeordneten Applikatoren vorgesehen ist, wobei sich die aus den Düsen austretenden Aerosolstrahlen auf der zu behandelnden Ware überlappen. Sind die einzelnen Applikatoren mit steuerbaren Ventilen versehen, wie dies erfindungsgemäß ebenfalls vorgesehen sein kann, so läßt sich eine gesteuerte Beaufschlagung der zu behandelnden Textilware je nach deren Lage und Breite erreichen. Eine Anpassung an die jeweilige Aufgabenstellung läßt sich dadurch erzielen, daß der Abstand zwischen dem Applikator bzw. den Applikatoren und der Bahn der Ware einstellbar ist.A uniform loading of the textile goods with the aerosol of the liquor can be achieved in particular if, as is proposed according to the invention, a plurality of applicators are provided which are arranged next to one another essentially transversely to the transport direction of the goods, the aerosol jets emerging from the nozzles on the overlapping treated goods. If the individual applicators are provided with controllable valves, as can also be provided according to the invention, a controlled loading of the textile goods to be treated can be achieved depending on their position and width. An adaptation to the respective task can be achieved in that the distance between the applicator or applicators and the web of the goods is adjustable.

Vorzugsweise ist der Applikator bzw. sind die Applikatoren derart angeordnet und ausgerichtet, daß die Ware bei Aufliegen auf einer der Walzen mit der Flotte beaufschlagt wird. Dabei kann diese Walze eine Siebwalze sein, also eine Walze, deren Umfang durch ein Sieb gebildet wird. Dies läßt ein besseres Eindringen der Flotte und/oder des Dampfes in die Ware erwarten, da das Wasser aus der Ware in Richtung auf die Siebwalze austreten kann. Diese Walze kann auchbeheizbar ausgebildet sein, was zu einer weiteren Aktivierung der auf die Ware aufgebrachten Flotte beiträgt.The applicator or applicators are preferably arranged and aligned in such a way that the product is loaded with the liquor when it rests on one of the rollers. This roller can be a screen roller, that is, a roller whose circumference is formed by a screen. This suggests a better penetration of the liquor and / or the steam into the goods, since the water from the goods is directed towards can emerge on the screen roller. This roller can also be designed to be heatable, which contributes to further activation of the liquor applied to the goods.

Aus verschiedenen Literaturstellen (DE-PS 47 553, DE-PS 885 534, EP 0 139 617 A2) sind zwar bereits verschiedende Arten von Applikatoren, auch zur Naßbehandlung von Textilware, bekannt, jedoch ist hierin die erfindungswesentliche Trennung des Dämpfers von einem ständig dampfgespülten Applikationsbehälter nicht angesprochen. Auch enthalten diese Druckschriften keinen Hinweis auf eine besonders bevorzugte Ausführungsform der Erfindung, bei der mittels Mehrstoffdüsen mit äußerer Mischung oder durch Verwendung von zwei auf einen Punkt der Textilware gerichteten Einstoffdüsen eine Aktivierung des Aerosols bzw. der Flotte erst auf der Textilbahn erzielt wird.Various types of applicators are known from various references (DE-PS 47 553, DE-PS 885 534, EP 0 139 617 A2), including for wet treatment of textile goods, but this is the separation of the damper from a steam-rinsed part which is essential to the invention Application container not addressed. These publications also contain no reference to a particularly preferred embodiment of the invention in which activation of the aerosol or the liquor is only achieved on the textile web by means of multi-component nozzles with an external mixture or by using two single-component nozzles directed at one point of the textile goods.

Eine besondere Ausführungsform der Erfindung beschäftigt sich mit dem Problem, daß die von der Düse zur Ware gesprühte Chemikalienflotte nicht vollständig auf die Textilware gelangt, vielmehr ein Teil als Chemikalikennebel im freien Dampfraum verbleibt. Selbst wenn die Applikatoren, wie dies erfindungsgemäß vorgesehen ist, in einem separaten Applikationsbehälter dem Dämpfer vorgeschaltet sind, wobei eine ständige Dampfspülung des Applikationsbehälters erfolgt, kann sich der Chemikaliennebel trotzdem an den Wänden und an der Decke des Applikationsbehälter festsetzen. Nach Vereinigung zu größeren Tropfen können diese auf die Ware herunterfallen und dort Flecken verursachen, die auf der Fertigware zu erkennen sind. Auch sind die zu den Applikatoren führenden Rohrleitungen für die Chemikalienflotte, sofern sie im Dampfraum verlegt sind - auch bei Kapselung in einem Gehäuse - kälter als die umgebende Dampfatmosphäre und führen zu Kondensatbildung, woraus ebenfalls Tropfflecken auf der Ware resultieren können. Das Beheizen von Innenflächen des Applikationsbehälter ist wegen der bereits diskutierten Gefahr von Verpuffungen im Applikationsbehälter kein gangbarer Weg, dieses Problem zu beseitigen.A particular embodiment of the invention deals with the problem that the chemical liquor sprayed from the nozzle to the goods does not reach the textile goods completely, rather a part remains as a chemical mist in the free vapor space. Even if the applicators, as provided according to the invention, are connected upstream of the damper in a separate application container, with the application container being continuously steam-rinsed, the chemical mist can still adhere to the walls and the ceiling of the application container. After being combined into larger drops, they can fall onto the goods and cause stains there, which can be seen on the finished goods. The pipelines leading to the applicators for the chemical fleet, provided they are installed in the steam room - even when encapsulated in a housing - are colder than the surrounding steam atmosphere and lead to the formation of condensate, which can also result in dripping stains on the goods. The heating of inner surfaces of the application container is due to the already discussed risk of deflagration in the application container not a viable way to solve this problem.

Die Erfindung sieht daher vorzugsweise vor, bei der beschriebenen Applikationsmethode, bei der in dem Applikationsbehälter in Dampfatmosphäre bei etwa 100° C und etwa 1 bar Druck auf die sich bewegende Warenbahn mittels Düsen das Gemisch aus wässriger Chemikalienflotte und Dampf aufgebracht wird, wobei die Applikation am Auslauf einer Leitwalze vorzugsweise über die gesamte Warenbreite mit aneinander gereiten Düsen vorgenommen wird, und zwar für beide Seiten der Textilware vorzugsweise mit ähnlicher Geometrie, um einen gleichseitigen Effekt des Prozesses zu erzielen, die zwischen dem Applikationsbehälter und dem Dämpfer befindliche Schleuse in Form eines gegenüber der Umgebungsatmosphäre geschlossenen Überströmschachtes auszubilden, durch den die Ware und der aus dem Dämpfer unter leichtem Überdruck in den Applikationsbehälter überströmende Dampf im Gleich- oder Gegenstrom geführt werden.The invention therefore preferably provides, in the application method described, in which in the application container in a steam atmosphere at about 100 ° C and about 1 bar pressure on the moving web of material by means of nozzles the mixture of aqueous chemical liquor and steam is applied, the application on Outfeed of a guide roller is preferably carried out over the entire width of the goods with nozzles that are juxtaposed, and for both sides of the textile goods preferably with a similar geometry, in order to achieve an equilateral effect of the process, the lock located between the application container and the damper in the form of an opposite one To form the ambient atmosphere of a closed overflow shaft through which the goods and the steam flowing from the damper under slight overpressure into the application container are conducted in cocurrent or countercurrent.

Dies hat nicht nur den Vorteil, daß der Überschußdampf des Dämpfers nicht verloren geht, sondern zum Spülen des Applikationsbehälters mitbenutzt wird, vielmehr ist auch gewährleistet, daß die Textilware permanent, also auch beim Übergang aus dem Applikationsbehälter in den Dämpfer, bei 100° C in Dampfatmosphäre verweilt und nicht - auch nicht kurzzeitig - mit kälterer Luft in Berührung kommt, woraus eine Abkühlung der Ware und eine Verschlechterung des erzielten Behandlungseffektes resultieren könnten.This not only has the advantage that the excess steam from the damper is not lost, but is also used to rinse the application container, rather it is also ensured that the textile goods are permanently in, i.e. also during the transition from the application container to the damper, at 100 ° C. Vapor atmosphere lingers and does not come into contact with colder air - not even briefly - which could result in cooling of the goods and a deterioration in the treatment effect achieved.

Bereits durch die vorbeschriebenen Maßnahme wird die Tröpfchenbildung deutlich reduziert. Eine weitere Verbesserung läßt sich dadurch erzielen, daß aus dem am Ausgang des Applikationsbehälters abgesaugten Luft-Dampf-Chemikalientröpfchengemisch die Chemikalientröpfchen entfernt werden, bevor das Gemisch der Umgebungsatmosphäre zugeführt wird. Dies erfolgt teilweise in als Absauggebläse verwendeten Radialventilatoren durch die Zentrifugalkraft. Zusätzlich kann ein handelsüblicher Demister nachgeschaltet sein. Dabei handelt es sich um ein Gewebe aus Edelstahl oder Kunststoffdraht, durch welches das Gemisch vorzugsweise lotrecht strömt. Während die gasförmigen Bestandteile sich frei in den Lücken des Gewebes bewegen können, sammeln sich die Tröpfchen aufgrund der Massenkräfte auf den Drähten an, vereinigen sich zu größeren Tröpfchen, tropfen schließlich lotrecht nach unten ab und werden abgeführt. Die abgeführte Flotte wird vorzugsweise rezirkuliert.The droplet formation is already significantly reduced by the measure described above. A further improvement can be achieved in that the chemical droplets are removed from the air-steam-chemical droplet mixture sucked off at the outlet of the application container before the mixture is supplied to the ambient atmosphere. This is done partly in centrifugal force in radial fans used as exhaust fans. In addition a standard demister can be installed downstream. This is a mesh made of stainless steel or plastic wire, through which the mixture preferably flows vertically. While the gaseous constituents can move freely in the gaps in the tissue, the droplets collect on the wires due to the mass forces, combine to form larger droplets, finally drip vertically downwards and are discharged. The discharged liquor is preferably recirculated.

Der Überwindung des "Tröpfchenproblems", also zur weitergehenden Vermeidung des Abtropfens von Flotte von Wänden des Applikationsbehälters oder - wenn auch gekapselten - Flottenleitungen lehrt die Erfindung ferner, im Applikationsbehälter außer den Bodenwänden alle Wände lotrecht oder mit mindestens 30° gegenüber der Waagerechten bis maximal 90° gegenüber der Waagerechten geneigt auszubilden. Hierdurch wird erreicht, daß sich ansetzende Tröpfchen, die sich zu größeren Tropfen vereinigen, nicht heruntertropfen, sondern die Innenwand des Applikationsbehälter entlanglaufen und so für die Ware schadlos abgeführt werden können. Durch eine Abdeckung, z.B. eine Metallblechfahne, oberhalb der Düsen der Applikatoren wird verhindert, daß herablaufende Flotte in den Düsestrahl gerät und dort zu Störungen führt. Die Düsen selbst befinden sich nur mit dem Düsenmund im Dampfraum, während der Rest, wie Düsenkörper und Anschlußleitungen, sich im Luftraum bei Umgebungstemperatur befindet. Die Düse ist - abgesehen von der Düsenstrahlöffnung - gegenüber dem Dampfraum des Applikationsbehälters abgedichtet. Der Vorteil dieser Konstruktion besteht in der freien Zugänglichkeit aller Leitungen, Verschraubungen, Ventile etc., ohne Ausbau. Wartung und Reparatur werden erheblich vereinfacht. Auch ist es durch geeignete Formgebung des Applikationsbehälters möglich, die Düsenbalken in kammerartigen Einbuchtungen der Applikationsbehälterwand so anzubringen, daß der Düsenmund sich in optimalem Abstand von der Textilware befindet, wobei gleichzeitig an den Düsenmund anschließende schräglaufende Innenwände des Applikationsbehälters ein Ableiten von kondensierender Chemikalienflotte ohne Gefahr eines Auftropfens auf die Textilware, wie bereits beschrieben, gewährleisten. Hervorzuheben ist, daß ein Abtropfen kondensierten Nebels auf die Ware oder die Walzen, über welche die Textilware geführt und welche Tropfen auf die Ware übertragen könnten, in besonders vorteilhafter Weise dann vollständing verhindert wird, wenn die Flottenleitungen außerhalb des Innenraumes des Applikationsbehälters liegen, d.h. also, die Düsen der Applikatoren am Düsenmund gegenüber dem Innenraum des Applikationsbehälters abgedichtet sind, und ferner unterhalb der Flottenleitungen (oder deren Kapselung) keine Warenbahn verläuft.The invention also teaches how to overcome the "droplet problem", that is, to further avoid dripping of the liquor from the walls of the application container or - even if encapsulated - liquor lines, in the application container all walls apart from the bottom walls perpendicular or at least 30 ° with respect to the horizontal up to a maximum of 90 ° training inclined to the horizontal. This ensures that droplets that form and form larger drops do not drip down, but run along the inner wall of the application container and can thus be removed without damage to the goods. A cover, for example a sheet metal flag, above the nozzles of the applicators prevents the liquor coming down from getting into the jet and causing faults there. The nozzles themselves are only in the steam space with the nozzle mouth, while the rest, such as the nozzle body and connecting lines, are in the air space at ambient temperature. Apart from the jet opening, the nozzle is sealed off from the vapor space of the application container. The advantage of this construction is the free accessibility of all lines, screw connections, valves etc., without removal. Maintenance and repair are considerably simplified. It is also possible by suitable shaping of the application container to mount the nozzle bars in chamber-like indentations of the application container wall in such a way that the nozzle mouth is at an optimal distance from the textile goods, while at the same time adjoining the nozzle mouth sloping inner walls of the application container ensure that the condensing chemical liquor is discharged without risk of dripping onto the textile goods, as already described. It should be emphasized that dripping of condensed mist onto the goods or the rollers, over which the textile goods are guided and which drops could be transferred to the goods, is completely prevented in a particularly advantageous manner if the liquor lines are outside the interior of the application container, ie , the nozzles of the applicators on the nozzle mouth are sealed off from the interior of the application container, and furthermore no web runs beneath the liquor lines (or their encapsulation).

Bei einer bevorzugten Ausführungsform der Erfindung ist der gesamte Düsenbalken als integrierte Baueinheit austauschbar. Befestigen und Abdichtung erfolgen über Schnellverschlüsse, so daß im Falle einer Störung an den Düsen ein Düsenbalken bei nur kurzem Produktionsausfall ausgetauscht werden kann. Auch zur Anpassung an bestimmte flottenbedingte Auftragkonditionen, z.B. bei sich ändernder Viskosität der verwendeten Chemikalienflotte, können die Düsen durch Auswechslung des Düsenbalkens gegen solche mit anderer Strahlcharakteristik ausgetauscht werden. Mit dem Austausch des Düsenbalkens lassen sich auch verschiedene Abstände zwischen dem Düsenmund und der Textilbahn erzielen.In a preferred embodiment of the invention, the entire nozzle bar is interchangeable as an integrated unit. Fastening and sealing take place via quick-release fasteners, so that in the event of a malfunction at the nozzles, a nozzle bar can be replaced with only a brief loss of production. Also to adapt to certain fleet-related order conditions, e.g. if the viscosity of the chemical liquor used changes, the nozzles can be exchanged for those with different jet characteristics by replacing the nozzle bar. By exchanging the nozzle bar, it is also possible to achieve different distances between the nozzle mouth and the textile web.

Erfindungsgemäß kann im übrigen auch vorgesehen sein, daß dem Dämpfer ein weiterer Applikationsbehälter nachgeschaltet ist, wobei von diesem die Textilware zunächst in den Dämpfer zurückgeführt und in jedem Fall erst aus dem Dämpfer heraus anderen Behandlungsschritten bzw. der Umgebungsatmosphäre zugeleitet wird. Durch sinnreiche Anordnung und Ausgestaltung der Applikationsbehälter ist es dabei z.B. möglich, vor dem Eintreten der Textilware in den Dämpfer lediglich eine Seite der Textilware mit einer bestimmten Chemikalienflotte zu behandeln, anschließend zu dämpfen, im Anschluß an den Dämpfprozeß die gegenüberliegende Seite - ggf. aber auch dieselbe Seite - mit einer weiteren, abweichenden Chemikalienflotte zu behandeln, anschließend ein erneutes Dämpfen durchzuführen, und die Textilware schließlich in die Atmosphäre auszutragen. Hierdurch ergeben sich weite Variationsmöglichkeiten in Anwendungsfällen, in denen das unterschiedliche Einwirken verschiedener Chemikalienflotten auf die beiden gegenüberliegenden Seiten der Textilware oder aber das zeitlich versetzte, durch einen Dämpfprozeß getrennte Aufbringen verschiedener Chemikalienflotten, ggf. aber auch die mehrmalige Behandlung mit einer einzigen Chemikalienflotte, zur Erzielung bestimmter Effekte wünschenswert ist. In dieser Ausführungsform der Erfindung wird ein besonders wichtiges Merkmal gesehen. Innerhalb des Erfindungsgedankens sind verschiedene Variationen der Anordnung von Dämpfer und vor- bzw. nachgeschaltetem Applikationsbehälter möglich. Beispielsweise kann ein Applikationsbehälter mit zwei (oder einem mehrfachen von zwei) einander gegenüberliegenden Düsenbalken mit nachgeschaltetem Dämpfer vorgesehen sein. Zusätzlich hierzu kann beispielsweise den Dämpfer auch ein weiteres Applikationsgehäuse mit Düsenbalken der vorstehend beschriebenen Art und Anordnung nachgeschaltet sein. In beiden Fällen ist es auch möglich, statt eines Applikationsbehälter mit mehreren Düsenbalken für jeden Applikationsbehälter lediglich einen einzigen Düsenbalken vorzusehen, wobei aber mindestens ein Applikationsbehälter pro Warenbahnseite vorhanden sein muß; auch in diesem Fall können für jede Seite der Warenbahn, also auf jeder Seite des Dämpfers, mehrfach zwei Applikationsbehältern (bzw. Düsenbalken) angeordnet werden.According to the invention, it can also be provided that a further application container is connected downstream of the damper, from which the textile goods are first returned to the damper and in any case are only passed out of the damper to other treatment steps or the ambient atmosphere. By means of a sensible arrangement and design of the application container, it is possible, for example, to treat only one side of the textile goods with a certain chemical liquor before the textile goods enter the damper, and then to steam them afterwards Steaming process to treat the opposite side - but possibly also the same side - with another, different chemical liquor, then carry out another steaming, and finally to discharge the textile goods into the atmosphere. This results in wide variations in applications in which the different effects of different chemical liquors on the two opposite sides of the textile goods or the time-delayed application of different chemical liquors, separated by a steaming process, but possibly also repeated treatment with a single chemical liquor, are achieved certain effects is desirable. A particularly important feature is seen in this embodiment of the invention. Various variations of the arrangement of damper and upstream or downstream application container are possible within the inventive concept. For example, an application container can be provided with two (or a multiple of two) opposing nozzle bars with a downstream damper. In addition to this, for example, the damper can also be followed by another application housing with nozzle bars of the type and arrangement described above. In both cases it is also possible to provide only a single nozzle bar for each application container instead of an application container with a plurality of nozzle bars, but at least one application container per web side must be present; In this case too, two application containers (or nozzle bars) can be arranged several times for each side of the web, that is to say on each side of the damper.

Mittels unterschiedlicher Kombinationen von Applikationsbehältern, ggf. mit unterschiedlichem Aufbau, sowie Däümpfer(n) lassen sich bei der Erfindung bspw. die folgenden Verfahren durchführen: Ein- oder mehrfacher beidseitiger Chemikalienauftrag gleicher oder unterschiedlicher Chemikalien (wobei für die einander gegenüberliegenden Seiten der Textilware gleiche Chemikalien vorgesehen sind bzw. vorgesehen sein können), mit anschließendem Verweilen zur Reaktion (Dämpfen); zusätzlich zu vorgenannter Vorgehensweise nach dem Dämpfen ebenfalls ein Chemikalienauftrag der beschriebenen Art und direkte Zuführung der Textilware zu nachfolgenden Prozessen mit nur geringer Verweilzeit nach dem letzten Chemikalienauftrag; ferner eine Vorgehensweise wie vorstehend angegeben, jedoch mit beliebiger Kombination von mehreren Chemikalienaufträgen (mit gleichen oder unterschiedlichen Chemikalien, wobei jedoch die beiden Seiten der Textilware jeweils mit derselben Chemikalie beaufschlagt werden) und beliebig einstellbare Verweilzeiten zwischen den verschiedenen Chemikalienaufträgen (also Dämpfzeiten).By means of different combinations of application containers, possibly with a different structure, and damper (s), the following methods can be carried out in the invention, for example: Single or multiple application of the same or different chemicals on both sides (whereby for the opposite ones The same chemicals are or can be provided on the textile goods side), with subsequent lingering for reaction (steaming); in addition to the above-mentioned procedure after steaming, a chemical application of the type described and direct feeding of the textile goods to subsequent processes with only a short dwell time after the last chemical application; Furthermore, a procedure as stated above, but with any combination of several chemical orders (with the same or different chemicals, but the two sides of the textile goods are each exposed to the same chemical) and any adjustable dwell times between the different chemical orders (i.e. steaming times).

Bei dem in Fig. 1 gezeigten Ausführungsbeispiel weist der Applikator ein erstes Rohr 2, das auf die Textilware 16 gerichtet ist, und ein zweites Rohr 4, dessen vorderes Ende in dem Austrittsbereich des ersten Rohres 2 mündet, auf. Aus dem ersten Rohr 2 tritt hochgespannter Dampf aus, durch das Rohr 4 wird - nicht oder nur geringfügig vorerwärmte - Flotte aufgebracht. Es bildet sich somit eine Mischung aus den aus dem Rohr 2 austretenden Dampf und der aus dem Rohr 4 austretenden Flotte, so daß ein Aerosol gebildet wird. Dieses Aerosol trifft mit hohem Druck auf die Ware 16 auf und dringt in diese ein.In the exemplary embodiment shown in FIG. 1, the applicator has a first tube 2, which is directed towards the textile fabric 16, and a second tube 4, the front end of which opens into the outlet region of the first tube 2. High-tension steam emerges from the first tube 2, and liquor is applied through the tube 4 — not or only slightly preheated. A mixture is thus formed from the steam emerging from tube 2 and the liquor emerging from tube 4, so that an aerosol is formed. This aerosol hits the product 16 with high pressure and penetrates into it.

Der Umstand, daß die Flotte erst unmittelbar vor Auftreffen auf die Textilware erwärmt wird, bewirkt, daß die chemischen Reaktionen erst in der Ware selbst stattfinden. Hier aber erfolgt die chemische Umsetzung, beispielsweise die des bei dem Bleichen eingesetzten Peroxides, wegen der hohen Temperatur des Dampfes schlagartig.The fact that the liquor is only heated immediately before it hits the textile product means that the chemical reactions only take place in the product itself. Here, however, the chemical conversion, for example that of the peroxide used in the bleaching, takes place suddenly because of the high temperature of the steam.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel ist der Applikator, hier mit dem Bezugszeichen 10 bezeichnet, zylindrisch ausgebildet: Ein erstes Rohr ist unter Ausbildung einer Kammer 24 beidseitig mit einer Scheibe abgeschlossen. Dabei bildet die eine Scheibe den Einlaß 12 und die andere Scheibe den Auslaß 14. Durch den Einlaß 12 wird die Flotte in die Kammer 24 eingebracht. Das erste Rohr 26 wird von einem spiralförmigen Heizelement 20 umfaßt, das Heizelement 20 wiederum von einem weiteren Rohr 22 aufgenommen, das in eine Halterung 28 eingeschraubt ist.In the exemplary embodiment shown in FIG. 2, the applicator, here designated by reference number 10, is cylindrical: a first tube is closed off on both sides with a disk, forming a chamber 24. One disk forms the inlet 12 and the other disk forms the outlet 14. The liquor is introduced into the chamber 24 through the inlet 12. The first tube 26 is surrounded by a spiral heating element 20, the heating element 20 is in turn received by a further tube 22 which is screwed into a holder 28.

Die in die Kammer 24 durch den Einlaß 12 eingedüste Flotte wird in dieser schlagartig verdampft und tritt unter hohem Druck aus dem Auslaß 14 unter Beaufschlagung der Ware 16 aus.The liquor injected into the chamber 24 through the inlet 12 is evaporated abruptly in the latter and emerges from the outlet 14 under high pressure while the goods 16 are loaded.

Anders als bei dem ersten Ausführungsbeispiel wird bei dem zweiten Ausführungsbeispiel also das Aerosol in einer geschlossenen Kammer gebildet und dieses Aerosol sodann auf die Warenbahn 16 aufgebracht.In contrast to the first exemplary embodiment, in the second exemplary embodiment the aerosol is formed in a closed chamber and this aerosol is then applied to the web 16.

In Figur 3 ist ein Ausführungsbeispiel des die Applikatoren aufnehmenden Applikationsbehälters 40 schematisch dargestellt. Die zu behandelnde Warenbahn wird über eine erste Walze 46 in den Behälter 40 eingeführt. Nach Passieren von Umlenkwalzen 48, 50 wird die Warenbahn über eine obere Umlenkwalze 52 geführt. Beidseits dieser oberen Umlenkwalze 52 sind erfindungsgemäß ausgebildete Applikatoren 10 angeordnet, durch die die Warenbahn mit der Flotte, insbesondere also einer Peroxid enthaltenden Lösung beaufschlagt wird. Die Warenbahn wird sodann über weitere Walzen 54, 56 um eine untere Umlenkwalze 58 geführt, in deren Bereich die Warenbahn erneut über weitere Applikatoren 10 mit der Flotte beaufschlagt wird. Nach Führung über Walzen 60, 62 wird die Warenbahn sodann durch eine Schleuse 64 aus dem Behälter 40 herausgeführt und einem - herkömmmlichen - Dämpfer zur weiteren Behandlung zugeführt.FIG. 3 schematically shows an exemplary embodiment of the application container 40 receiving the applicators. The material web to be treated is introduced into the container 40 via a first roller 46. After passing deflection rollers 48, 50, the material web is guided over an upper deflection roller 52. Applicators 10 designed according to the invention are arranged on both sides of this upper deflecting roller 52, through which the liquor, in particular a solution containing peroxide, is applied to the web. The web is then guided over further rollers 54, 56 around a lower deflection roller 58, in the area of which the web is again acted upon by the fleet via further applicators 10. After being guided over rollers 60, 62, the material web is then led out of the container 40 through a lock 64 and fed to a — conventional — damper for further treatment.

Zum permanenten Spülen des Innenraumes des Behälters 40 ist dieser mit einer Mehrzahl von Dampfeintrittsrohren 66 ausgebildet, die bevorzugt oberhalb der Applikatoren 10 angeordnet sind. Im unteren Bereich des Behälters 40 ist ein Gebläse 68 angeordnet, das den in den Behälter 40 über die Dampfeintrittsrohre 66 eingeführten Dampf aus diesem wieder abführt. Insgesamt ist dabei natürlich dafür gesorgt, daß der Dampfspülvorgang tatsächlich unter ständigem Zuführen von Dampf in den Behälter unter Verhinderung eines "Rückschlagens" von Behälteratmosphäre in die Dampfeintrittsrohre stattfindet.For the permanent flushing of the interior of the container 40, the latter is designed with a plurality of steam inlet pipes 66, which are preferably arranged above the applicators 10. A fan 68 is arranged in the lower region of the container 40 and removes the steam introduced into the container 40 via the steam inlet pipes 66. Overall, it is of course ensured that the steam purging process is actually carried out by continuously supplying steam into the container while preventing the container atmosphere from "kicking back" into the steam inlet pipes takes place.

Es läßt sich dabei erkennen, daß bei der Vorrichtung nach der Erfindung der Applikationsbehälter 40, in dem die das Peroxid bzw. eine ähnliche Substanz beinhaltende Flotte über die Applikatoren 10 auf die Warenbahn aufgebracht wird, von dem eigentlichen Dämpfer getrennt ist. Durch diese räumliche Trennung wird erreicht, daß das Volumen des Raumes, der die Applikatoren aufnimmt, relativ gering sein kann. Bei Betrieb wird der die Applikatoren 10 aufnehmende Behälter 40 somit ständig dampfgespült, so daß das Peroxid, das nicht auf das Gewebe gelangt ist und dessen Aufkonzentration droht, ständig abgeführt wird. Eine Verpuffung ist somit zuverlässig ausgeschlossen.It can be seen here that in the device according to the invention the application container 40, in which the liquor containing the peroxide or a similar substance is applied to the material web via the applicators 10, is separate from the actual damper. This spatial separation ensures that the volume of the space that receives the applicators can be relatively small. During operation, the container 40 receiving the applicators 10 is thus constantly steam-rinsed, so that the peroxide which has not reached the tissue and is at risk of being concentrated is continuously removed. A deflagration is therefore reliably excluded.

Vorzugsweise wird die beim Dampfspülen aus dem Behälter 40 herausgeführte Flotte, die nicht auf der Textilware verbraucht worden ist, rezirkuliert, wodurch nicht nur in umweltfreundlicher Weise verhindert wird, daß die diesbezüglichen Chemikalien in die Atmosphäre gelangen, sondern auch die Wirtschaftlichkeit deutlich erhöht werden kann.Preferably, the liquor which has been removed from the container 40 during the steam rinsing and which has not been used up on the textile goods is recirculated, which not only prevents the chemicals in question from being released into the atmosphere in an environmentally friendly manner, but can also significantly increase the economy.

Bei dem in Fig. 4 gezeigten Ausführungsbeispiel wird die Textilware 16 Inhalt des Applikationsbehälters 40 wie beim Ausführungsbeispiel von Fig. 3 von schräg rechts unten, in der Zeichnung gesehen, nach schräg rechts oben durch den Applikationsbehälter 40 geführt, den sie dann in Richtung des Pfeiles 70 zu den in Fig. 4 nicht gezeigten Dämpfer verläßt. Sämtliche Innenwände des Applikationsbehälters 40 sind entweder lotrecht oder aber mit einem Winkel von mindestens 30° gegenüber der Waagerechten angeordnet, so daß sich ansetzende Tröpfchen, die sich zu größeren Tropfen vereinigen, nicht heruntertropfen, sondern die Wand entlanglaufen und so schadlos für die Textilware 16 abgeführt werden können. Die Düsen bzw. Applikatoren 10 sind in einem Düsenbalken 72 angeordnet, der als integrierte Baueinheit mittels Schnellverschlüssen 74, 76 austauschbar in eine entsprechende Öffnung der Wand des Applikationsbehälters 40 eingesetzt ist. Dabei befindet sich nur ein Düsenmund 78, aus dem ein Düsenstrahl austritt, im Innenraum des Applikationsbehälters 40, während die übrigen Bauteile, wie Leitungen, Verschraubungen, Ventile etc., in der aus der Zeichnung ersichtlichen Weise von außen, also von der Umgebungsatmosphäre her, frei zugänglich sind. Der aus dem Düsenmund 78 austretende Düsenstrahl ist durch Abdeckungen 79, z.B. als Metallblechfahne ausgebildet, so abgeblendet, daß Chemikalienflotte tatsächlich im wesentlichen nur auf die Textilware 16 gelangen und dort ihren bestimmungsgemäßen Zweck erfüllen kann.In the exemplary embodiment shown in FIG. 4, the textile goods 16 content of the application container 40, as in the exemplary embodiment of FIG. 3, is guided obliquely from the bottom right, in the drawing, obliquely to the top right through the application container 40, which it then directs in the direction of the arrow 70 to the damper not shown in Fig. 4 leaves. All of the inner walls of the application container 40 are either arranged perpendicularly or at an angle of at least 30 ° with respect to the horizontal, so that droplets which form larger drops do not drip down, but run along the wall and are thus discharged without damage to the textile goods 16 can be. The nozzles or applicators 10 are arranged in a nozzle bar 72 which, as an integrated structural unit, can be exchanged for a corresponding one by means of quick-release fasteners 74, 76 Opening the wall of the application container 40 is inserted. There is only one nozzle mouth 78, from which a nozzle jet emerges, in the interior of the application container 40, while the other components, such as lines, screw connections, valves, etc., are visible from the outside, that is to say from the ambient atmosphere, in the manner shown in the drawing, are freely accessible. The nozzle jet emerging from the nozzle mouth 78 is dimmed by covers 79, for example as a sheet metal flag, in such a way that chemical liquor actually only reaches the textile goods 16 and can fulfill its intended purpose there.

An den Lagerseiten der Walzen 56, 58, 62, also in den entsprechenden Stirnwänden, parallel zur Zeichnungsebene von Fig. 4, des Applikationsbehälters 40, sind Fenster 80 mit Lampen 82 angebracht, um die Düsenstrahlen beleuchten zu können. Oberhalb des Düsenbalkens 72 sind schräge Sichtfenster 84 über die gesamte Breite der Vorrichtung vorhanden. Zusammen mit der Beleuchtung ist somit eine laufende optische Überwachung der Düsenstrahlen während des Betriebes möglich. Selbstverständlich wäre es auch möglich, statt einer rein optischen Überwachung durch eine Bedienungsperson eine automatische Überwachung vorzunehmen, z.B. mittels entsprechender Sensoren und Regelungseinrichtungen.On the bearing sides of the rollers 56, 58, 62, that is to say in the corresponding end walls, parallel to the drawing plane of FIG. 4, of the application container 40, windows 80 with lamps 82 are attached in order to be able to illuminate the jet streams. Above the nozzle bar 72, oblique viewing windows 84 are present over the entire width of the device. Together with the lighting, it is therefore possible to continuously monitor the nozzle jets during operation. Of course, it would also be possible to carry out automatic monitoring instead of purely optical monitoring by an operator, e.g. by means of appropriate sensors and control devices.

Gegenüber dem Düsenbalken 72 ist, wie Fig. 4 erkennen läßt, ein Schottblech 86 vorgesehen, welches verhindert, daß von der Walze 58 abprallende Tröpfchen direkt auf die Textilware 16 gelangen. Der Düsenstrahl tritt im übrigen so aus dem Düsenmund 78 aus - die Düsen sind drehbar um ihren Befestigungsmittelpunkt angebracht, wodurch sich auch eine bessere Flexibilität hinsichtlich der Einstellung für verschiedene Warenartikel ergibt -, daß der Düsenstrahl etwa in dem Anlage- bzw. Kontaktbereich der Textilware 16 mit der Walze 58 auftrifft. Durch diese Art des Auftreffens, vorzugsweise in Transportrichtung der Textilware 16 unmittelbar hinter der entsprechende Kontaktlinie, wird ein "Saugeffekt" ausgenutzt, der auf dem leichten Expandieren der Textilware 16 nach dem Passieren der Walze 58 beruht, wodurch eine besonders intensive Durchdringung der Ware mit der Chemikalienflotte gewährleistet wird.4, a partition plate 86 is provided, which prevents droplets bouncing off the roller 58 from reaching the textile fabric 16 directly. The nozzle jet also emerges from the nozzle mouth 78 (the nozzles can be rotated about their center of attachment, which also results in better flexibility with regard to the setting for various articles of goods) such that the nozzle jet is located approximately in the contact area of the textile goods 16 hits with the roller 58. This type of impact, preferably in the direction of transport of the textile goods 16 directly behind the corresponding contact line, a "suction effect" is used, which is based on the slight expansion of the textile goods 16 after passing through the roller 58, which ensures a particularly intensive penetration of the goods with the chemical liquor.

Bei dem in Fig. 5 gezeigten Ausführungsbeispiel ist erkennbar, daß dem Applikationsbehälter 40 ein Dämpfer 90 nachgeschaltet ist, dessen Atmosphäre mit dem Applikationsbehälter 40 über einen gegenüber der Umgebungsatmosphäre abgeschlossenen Überströmschacht 92 in Verbindung steht. Durch den Überströmschacht 92, den die Ware in Fig. 5 von links nach rechts passiert, strömt ständig Dampf aus dem gegenüber dem Applikationsbehälter 40 unter leichtem Überdruck stehenden Dämpfer 90 in den Applikationsbehälter 40 ein und wird dort in der bereits in Verbindung mit Fig. 3 beschriebenen Weise zum Dampfspülen verwendet. Der Dampf durchströmt den Überströmschacht bei diesem Ausführungsbeispiel im Gegenstrom zur Textilware 16. Der Applikationsbehälter weist insgesamt vier Düsenbalken 72 der bereits beschriebenen Art auf, wobei die Absaugung des Gemischs aus Dampf, Chemikalien und Luft aus dem Inneren des Applikationsbehälters 40 mittels des Gebläses 68 erfolgt. Die Düsenbalken 72 sind dem Applikationsbehälter 40 gleichsam in Form einzelner Kammern zugeordnet, wobei gewährleistet ist, daß die beiden einander gegenüberliegenden Seiten der Textilware 16 gleichmäßig beaufschlagt werden und keine Tropfen von Wänden oder Rohrleitungen des Applikationsbehälters 40 auf das Gewebe der Textilware 16 gelangen. Jeweils zwei gegenüberliegende Balkengehäuse der Düsenbalken 72 gehören, wie aus der Zeichnung ersichtlich, zusammen, d.h., daß in ihnen jeweils dieselbe Chemikalienflotte auf die Textilware 16 aufgebracht wird. Ein Applikationsbehälter der in Fig. 5 gezeigten und vorstehend beschriebenen Art ist stufenweise erweiterbar, d.h. es sind sowohl zwei als auch vier, sechs und mehr Düsenbalken 72 in einem einzigen Applikationsbehälter 40 denkbar, wenn für den Prozeß das Nacheinanderauftragen unterschiedlicher Chemikalien notwendig ist.In the exemplary embodiment shown in FIG. 5, it can be seen that the application container 40 is followed by a damper 90, the atmosphere of which is connected to the application container 40 via an overflow shaft 92 which is sealed off from the ambient atmosphere. Through the overflow shaft 92, which the goods pass from left to right in FIG. 5, steam flows continuously from the damper 90, which is under slightly overpressure relative to the application container 40, into the application container 40 and is there in the already in connection with FIG. 3 described way used for steam rinsing. The steam flows through the overflow shaft in this exemplary embodiment in countercurrent to the textile product 16. The application container has a total of four nozzle bars 72 of the type already described, the mixture of steam, chemicals and air being sucked out of the interior of the application container 40 by means of the fan 68. The nozzle bars 72 are assigned to the application container 40, as it were, in the form of individual chambers, it being ensured that the two opposite sides of the textile fabric 16 are acted upon uniformly and that no drops from the walls or pipes of the application container 40 get onto the fabric of the textile fabric 16. As can be seen from the drawing, two opposite bar housings of the nozzle bars 72 belong together, that is to say that the same chemical liquor is applied to the textile goods 16 in each of them. An application container of the type shown in FIG. 5 and described above can be expanded in stages, ie both two, four, six and more nozzle bars 72 are conceivable in a single application container 40 if the process is to be applied one after the other different chemicals is necessary.

Ein derartiger Applikationsbehälter mit zwei oder einem mehrfachen von Düsenbalken 72 kann sowohl am Eingang des Dämpfers 90 als auch an seinem Ausgang angebracht sein, wenn es für den Prozeß von Vorteil ist. Beim Ausführungsbeispiel von Fig. 6 handelt es sich um eine Ausbildung der Vorrichtung nach der Erfindung, bei der dem Dämpfer 90 ein erster Applikationsbehälter 40 und ein weiterer Applikationsbehälter 94 zugeordnet sind, die jeweils einen einzigen Düsenbalken 72 aufweisen. Jedem Applikationsbehälter ist ein Absauggebläse 68 der bereits beschriebenen Art zugeordnet. Mittels der in Fig. 6 gezeigten Vorrichtung kann die Textilware 16 sowohl vor als auch nach einer bestimmten Chemikalienapplikation zur Reaktion im Dämpfer 90 verweilen. Auch hier ist natürlich ein Nacheinanderschalten von 2, 4, 6 oder einem mehrfachen von Düsenbalken 72 bzw. "Applikationskammern" in dem jeweiligen Applikationsbehälter 40 bzw. 94 möglich.Such an application container with two or a plurality of nozzle bars 72 can be attached both at the inlet of the damper 90 and at its outlet if it is advantageous for the process. 6 is an embodiment of the device according to the invention, in which the damper 90 is assigned a first application container 40 and a further application container 94, each of which has a single nozzle bar 72. A suction fan 68 of the type already described is assigned to each application container. By means of the device shown in FIG. 6, the textile fabric 16 can remain in the damper 90 both before and after a certain chemical application for reaction. Here, too, it is of course possible to connect 2, 4, 6 or a plurality of nozzle bars 72 or “application chambers” in series in the respective application container 40 or 94.

Eine kontinuirliche Dampfströmung vom Dämpfer 90 zum Applikationsbehälter 40 bzw. weiteren Applikationsbehältern 94 läßt sich sicherstellen, in dem dem Dämpfer 90 Dampf mit konstant geregeltem Zufluß zugeführt wird. Da die Textilware 16 und die Flotte bereits aufgeheizt sind, treten im Dämpfer 90 abgesehen von der Abströmung von Dampf durch den Überströmschacht 92 als Dampfverbrauch nur die Verluste über die Oberfläche auf, die unabhängig von der Textilware sind. Eine Kontrolle, ob Tröpfchennebel vom Applikationsbehälter 40 bzw. 94 in den Dämpfer 90 eindringt, kann optisch durch die Bedienungsperson beim Einfahren der Anlage erfolgen. Natürlich ist aber auch eine sensorgeregelte Steuerung möglich. Die Absaugung mittels der Absauggebläse 68 erfolgt mit konstantem Volumenstrom. Das je nach Warenartikel unterschiedliche Dampfangebot an der Absaugung wird kompensiert durch ein mehr oder weniger starkes Ansaugen von Umgebungsluft.A continuous steam flow from the damper 90 to the application container 40 or further application containers 94 can be ensured by supplying steam to the damper 90 with a constantly regulated inflow. Since the textile fabric 16 and the liquor have already been heated up, apart from the outflow of steam through the overflow duct 92, only the losses over the surface which are independent of the textile product occur in the damper 90 as steam consumption. The operator can visually check whether droplet mist from the application container 40 or 94 penetrates into the damper 90 when the system is being run in. Of course, sensor-controlled control is also possible. The suction by means of the suction fan 68 takes place with a constant volume flow. The range of steam available on the extraction system, which varies depending on the product, is compensated for by a more or less strong suction of ambient air.

Die in der vorstehenden Beschreibung, in der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebigen Kombinationen für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the drawing and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments.
