Abstract

A method and apparatus for the wet treatment of endless textile material wherein the treatment liquor is scooped up by ladles or dippers disposed on a drum rotatably mounted within a boiler, the dippers carrying the treatment liquor in the drum rotation while, at the same time, the textile material rests on the outside wall of the drum and is carried along. The treatment liquor emerges from the dippers, wets and penetrates the textile material for its intensive wet treatment. The textile material and treatment liquor return to the lower area of the boiler where they are again taken up for renewed similar treatment.

Description

Die Erfindung betrifft ein Verfahren und eine zugehörige Vorrichtung je zur Naßbehandlung von Textilgut in endloser Form gemäß Oberbegriff des Patentanspruchs 1 bzw. 5.5. The invention relates to a method and an associated device, each for the wet treatment of textile goods in endless form, according to the preamble of patent claims 1 and 5, respectively.

Bereits aus der FR-A 20 21 131 sind ein Verfahren und eine Vorrichtung der vorstehend bezeichneten Gattung bekannt, bei welcher Vorrichtung die Trommel innerhalb eines Kessels angeordnet und für Behandlungsflotte durchlässig ausgebildet ist. Die Trommel ist dabei soweit im oberen Teil des Kessels angeordnet, daß unter ihr ein Raum verbleibt,in dem sich ein Behandlungsflotten-Sumpf bei entsprechender Füllung mit Behandlungsflotte ausbilden kann. Das Textilgut ist in der Form eines endlosen Gebildes über den jeweils oberen Teil der Trommel geführt und durchläuft im übrigen den Behandlungsflotten-Sumpf. Die Trommel selbst ist aus in Axialrichtung hintereinander angeordneten Scheibenelementen gebildet, die auf einer Hohlwelle angeordnet sind, wobei das Innere der Hohlachse mit mindestens einigen der Scheibenzwischenräume in kommunizierender Verbindung steht. Die eigentliche äußere Auflagefläche der Trommel für das zu behandelnde Textilgut ist von den äußeren Umfängen der Scheibenelemente gebildet. Die genannte hohle Ausbildung der Trommelwelle dient der Zuführung von Behandlungsflotte vom Inneren der Trommel her zum Textilgut.FR-A 20 21 131 already discloses a method and a device of the type described above, in which device the drum is arranged within a boiler and is designed to be permeable to the treatment liquor. The drum is arranged so far in the upper part of the boiler that a space remains below it in which a treatment liquor sump can be formed with the appropriate filling with treatment liquor. The textile material is guided in the form of an endless structure over the upper part of the drum and passes through the treatment liquor sump. The drum itself is formed from disc elements arranged one behind the other in the axial direction and arranged on a hollow shaft, the interior of the hollow axis being in communication with at least some of the disc spaces. The actual outer contact surface of the drum for the textile material to be treated is formed by the outer circumferences of the disc elements. The hollow construction of the drum shaft mentioned serves to supply treatment liquor from the inside of the drum to the textile material.

Die Naßbehandlung des Textilguts erfolgt mittels dieser bekannten Vorrichtung und des zugehörigen Verfahrens einerseits während der Hindurchführung des Textilguts durch den Behandlungsflotten-Sumpf und andererseits unter der Einwirkung der über die Hohlwelle zugeführten Behandlungsflotte. Um letzteres möglich zu machen, muß die Behandlungsflotte mit verhältnismäßig hohem Druck durch die Hohlwelle zugeführt werden, damit sie noch bis zum Außenumfang der aus den Scheibenelementen gebildeten Trommel verbracht werden kann und dort auf das Textilgut auftrifft. Das Ablegen des Textilguts auf der aus den Scheibenelementen gebildeten Trommel ist jedoch insbesondere bei empfindlichem Textilgut in keiner Weise für dessen Qualität förderlich, da sich durch das Auflegen auf dem Umfangsrandflächen der Scheibenelemente streifenförmige Druckspuren am Textilgut ausbilden können. Das Aufbringen der Behandlungsflotte auf das Textilgut vom Inneren der Hohlwelle aus macht einen hohen Energieaufwand erforderlich, und zwar insbesondere wegen des notwendigen hohen Austrittsdrucks und der in der Hohlwelle auftretenden Druckverluste. Andererseits ist die Aufbringung der Behandlungsflotte im Wege des Aufspritzens von der Hohlwelle aus auf das Textilgut nur eine verhältnismäßig wenig intensive Behandlung, da das Textilgut hierbei nicht besonders intensiv von Behandlungsflotte durchdrungen wird, sondern lediglich mit dieser quasi besprüht wird. Der Energieaufwand zur Zuführung der Behandlungsflotte vom Inneren der Hohlwelle aus zum Textilgut hin ist auch insoweit bereits übermäßig groß, da die beim Austritt aus der Hohlwelle jeweils nach unten gerichteten Teile der Behandlungsflotte überhaupt nicht mehr auf das Textilgut zur Einwirkung gebracht werden, da dort ja das Textilgut ja nicht mehr an der Außenseite der Trommel aufliegt.The wet treatment of the textile goods takes place by means of this known device and the associated method on the one hand during the passage of the textile goods through the treatment liquor sump and on the other hand under the influence of the treatment liquor supplied via the hollow shaft. In order to make the latter possible, the treatment liquor must be fed through the hollow shaft at a relatively high pressure, so that it can still be brought to the outer circumference of the drum formed from the disk elements and strikes the textile material there. However, placing the textile goods on the drum formed from the disk elements is in no way conducive to its quality, especially in the case of sensitive textile goods, since strip-like pressure marks can form on the textile goods by being placed on the peripheral edge surfaces of the disk elements. The application of the treatment liquor to the textile material from the inside of the hollow shaft requires a large amount of energy, in particular because of the necessary high outlet pressure and the pressure losses occurring in the hollow shaft. On the other hand, the application of the treatment liquor by spraying from the hollow shaft onto the textile material is only a relatively low-intensity treatment, since the textile material is not penetrated particularly intensively by the treatment liquid, but is merely sprayed with it. The energy expenditure for supplying the treatment liquor from the interior of the hollow shaft to the textile goods is already excessively large, since the parts of the treatment liquor which are directed downward when they emerge from the hollow shaft are no longer at all affected by the textile goods, since that is there Textile no longer lies on the outside of the drum.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde das Verfahren und die Vorrichtung der eingangs bezeichneten Gattung so auszubilden, daß mit einem sogenannten kurzen Flottenverhältnis eine verlängerte intensive Behandlung des Textilguts durch Verlängerung der Behandlungsstrecke und eine weitere Intensivierung der Behandlung erreicht ist und im übrigen das Textilgut nahezu keiner Zugbelastung ausgesetzt ist, die sich auf seine Qualität und insbesondere Egalität auswirken könnte. Dabei ist gleichzeitig darauf zu achten, daß kein besonderer Energieaufwand für die Zuführung der Behandlungsflotte zum Textilgut erforderlich ist, jedenfalls kein übermäßig hoher Energieaufwand.The present invention is therefore based on the object of designing the method and the device of the type mentioned at the outset in such a way that with a so-called short liquor ratio, prolonged intensive treatment of the textile goods is achieved by lengthening the treatment section and further intensifying the treatment, and the textile goods are virtually the same is not exposed to a tensile load that could affect its quality and, in particular, levelness. At the same time, care must be taken to ensure that no particular energy expenditure is required for the supply of the treatment liquor to the textile goods, in any case no excessively high energy expenditure.

Diese Aufgabe wird erfindungsgemäß in verfahrens- bzw. vorrichtungstechnischer Hinsicht durch die Maßnahmen des kennzeichnenden Teils des Patentanspruchs 1 bzw. 5 gelöst.This object is achieved according to the invention in procedural or device-technical terms by the measures of the characterizing part of patent claim 1 or 5.

Vorteilhafte Weiterbildungen sind aus den jeweils zugehörigen Unteransprüche zu ersehen.Advantageous further developments can be seen from the associated subclaims.

Durch die erfindungsgemäße Ausbildung ist in vorteilhafter Weise erreicht, daß das Textilgut etwa entlang eines Viertels des Umfangs der Trommel intensiv mit der Behandlungsflotte in Berührung steht, nämlich entlang des vom obersten Punkt der Trommel ausgehenden Viertels des Umfangs, auf welchem Umfangsabschnitt die Behandlungsflotte aus den Schöpfgefäßen austritt und dabei durch das Textilgut hindurchtritt. Andererseits wird auf der gegenüberliegenden Seite der Trommel von dieser das abgetafelte Textilgut aufgenommen, wobei es kaum zu einem Anheben desselben kommt, da das Textilgut etwa von halber Höhe der Trommel aus angehoben wird und nahezu bis zu dieser Höhe in abgetafelter Form vorliegt. Soweit das Textilgut in abgetafelter Form im Inneren des Kessels noch in Behandlungsflotte liegt, dient dies nicht der eigentlichen Naßbehandlung; ein Nebeneffekt dieser "schwimmenden" Lagerung ist lediglich der, daß das Textilgut entlang der Innenwand des Kessels leichter weiterrutscht. Die Einhaltung kurzer Flottenverhältnisse ist ohne weiteres dadurch gewährleistet, daß im eigentlichen Behandlungsapparat nur soviel Behandlungsflotte enthalten sein muß, daß sie mittels der Schöpfgefäße der Trommel aufschöpfbar ist.The design according to the invention advantageously ensures that the textile material is in intensive contact with the treatment liquor along a quarter of the circumference of the drum, namely along the quarter of the circumference starting from the uppermost point of the drum, on which circumferential section the treatment liquor from the scoops emerges and thereby passes through the textile material. On the other hand, on the opposite side of the drum, the stacked textile material is picked up, with hardly any lifting of the textile material, since the textile material is raised from half the height of the drum and is present in a plate form almost up to this height. Insofar as the textile material is still in the treatment liquor in the form of a tablet in the interior of the boiler, this does not serve the actual wet treatment; a side effect of this "floating" storage is only that the textile material slips more easily along the inner wall of the boiler. Adherence to short liquor ratios is easily ensured by the fact that the actual treatment apparatus only has to contain so much treatment liquor that it can be scooped up by means of the scoop vessels of the drum.

Im folgenden wird die Erfindung unter Bezugnahme auf zwei in den Zeichnungen dargestellte besondere Ausführungsbeispiele näher erläutert; in den Zeichnungen zeigen:The invention is explained in more detail below with reference to two special exemplary embodiments illustrated in the drawings; in the drawings show:

Fig. 1 einen Querschnitt durch eine erste Ausführungsform der erfindungsgemäßen Vorrichtung, bei der die Behandlungsflotte mittels der Schöpfgefäße der Trommel aus dem Inneren des Kessels der Vorrichtung aufgeschöpft wird, undFig. 1 shows a cross section through a first embodiment of the device according to the invention, in which the treatment liquor is scooped out of the interior of the boiler of the device by means of the scoop vessels of the drum, and

Fig. 2 eine zweite Ausführungsform der erfindungsgemäßen Vorrichtung, bei der die Behandlungsflotte mittels der Schöpfgefäße der Trommel vom Inneren der Trommel herkommend aufgeschöpft wird.Fig. 2 shows a second embodiment of the device according to the invention, in which the treatment liquor is scooped up from the inside of the drum by means of the scoop vessels of the drum.

Wesentlichste Bestandteile der erfindungsgemäßen Vorrichtung sind ein in sich geschlossener Kessel 1 und eine in diesem drehbar gelagerte Trommel 2 mit Schöpfgefäßen 3 Zumindest in zweckmäßiger Weitergestaltung ist die Trommel 2 eine motorisch angetriebene Trommel. Bei beiden dargestellten Ausführungsformen ist die Trommel 2 gegenüber dem Kessel 1 nach oben exzentrisch gelagert, um unterhalb der Trommel einen hinreichenden Raum zur Aufnahme abgetafelten Textilguts 4 zur Verfügung zu stellen.The most important components of the device according to the invention are a self-contained boiler 1 and a drum 2 rotatably mounted therein with scooping vessels 3. At least in an expedient further development, the drum 2 is a motor-driven drum. In both of the illustrated embodiments, the drum 2 is mounted eccentrically upwards relative to the boiler 1 in order to provide sufficient space below the drum for receiving stacked textile goods 4.

Bei dem ersten Ausführungsbeispiel gemäß Fig. 1 ist die Trommel 2 als in sich geschlossene zylindrische Trommel mit außen aufgesetzten Schöpfgefäßen 3 gestaltet. Die Trommel 2 ist in Richtung des Pfeils A in Rotation versetzbar. Bei dieser Rotation nehmen die Schöpfgefäße 3, wie ohne weiteres aus Fig. 1 erkennbar ist, Behandlungsflotte aus einem Behandlungsflotten-Sumpf 5 im unteren Bereich des Inneren des Kessels 1 auf. Die aufgenommene Behandlungsflotte wird von den Schöpfgefäßen 3 bei der Rotation der Trommel 2 mitgenommen und läuft aus den Schöpfgefäßen 3 erst dann aus, wenn diese den oberen Scheitelpunkt der Rotationsbewegung der Trommel 2 überschreiten.In the first embodiment shown in FIG. 1, the drum 2 is designed as a self-contained cylindrical drum with scoops 3 placed on the outside. The drum 2 can be set in rotation in the direction of arrow A. During this rotation, the scoops 3, as can be readily seen from FIG. 1, take up treatment liquor from a treatment liquor sump 5 in the lower region of the interior of the boiler 1. The absorbed treatment liquor is taken along by the scoops 3 when the drum 2 rotates and only runs out of the scoops 3 when they exceed the upper vertex of the rotary movement of the drum 2.

Das Textilgut 4 wird gemäß Darstellung in Fig. 1 etwa von der halben Höhe der Trommel 2 aus von dieser aufgenommen und an dem Äußeren der Trommel 2 abgelegt bei der Trommelrotation mitgenommen. Beim Überschreiten des Scheitelpunkts der Trommelrotation aus den Schöpfgefäßen 3 austretende Behandlungsflotte gelangt dabei zunächst zu der auf der Trommel 2 abgelegten Seite des Textilguts 4, durchströmt dann das Textilgut und fließt praktisch beidseitig entlang des Textilguts nach unten in Richtung auf den Flottenbehandlungs-Sumpf 5 ab. Etwa dem Aufnahmebereich der Trommel 2 für das Textilgut 4 gegenüberliegend ist der Trommel 2 eine Abnahmeeinrichtung in der Form einer Walze 6 nachgeschlatet, über die das Textilgut 4 von der Trommel 2 abgenommen wird, woran anschließend das Textilgut 4 etwa ziehharmonikaförmig frei abgetafelt wird. Dieses abgetafelte Textilgut rutscht dabei fortlaufend durch den Behandlungsflotten-Sumpf 5, bis es schließlich wieder von dem gemäß Fig. 1 linken Teil der Trommel 2 aufgenommen wird.The textile material 4 is, as shown in FIG. 1, taken up from about half the height of the drum 2 and deposited on the outside of the drum 2 when it is rotated. When the apex of the drum rotation from the scoops 3, the treatment liquor first reaches the side of the textile material 4 deposited on the drum 2, then flows through the textile material and flows down practically on both sides along the textile material downwards in the direction of the liquor treatment swamp 5. For example, opposite the receiving area of the drum 2 for the textile material 4, the drum 2 has a removal device in the form of a roller 6, by means of which the textile material 4 is removed from the drum 2, after which the textile material 4 is then freely stacked in an accordion shape. This paneled textile material continuously slips through the treatment liquor sump 5 until it is finally taken up again by the left part of the drum 2 according to FIG. 1.

Etwa die untere Hälfte der Trommel 2 und ihre zugehörigen Schöpfgefäße 3 umgebend ist ein Leitblech 7 vorgesehen, das für die Behandlungsflotte durchlässig ist, so daß die Behandlungsflotte von ihrem Sumpf 5 aus Zutritt zu den Schöpfgefäßen 3 findet.Around the lower half of the drum 2 and its associated scoops 3 surrounding a baffle 7 is provided, which is permeable to the treatment liquor, so that the treatment liquor from their sump 5 access to the scoops 3.

Selbstverständlich müssen die Schöpfgefäße 3 nicht an der Außenseite der Trommel 2 angesetzt sein; vielmehr können die Schöpfgefäße auch durchaus zum Inneren der Trommel 2 hin angeordnet sein, wobei ihre Basis zusammen mit den verbleibenden Bereichen des eigentlichen Mantels der Trommel 2 eine für Behandlungsflotte undurchlässige Wandung bildet, so daß die Behandlungsflotte wiederum in der beschriebenen Weise aus dem Sumpf 5 aufschöpfbar und bei der Rotation der Trommel 2 mitnehmbar ist, bis sie aus den Schöpfgefäßen 3 nach Überschreitung des Rotationsscheitels austritt.Of course, the scoops 3 do not have to be attached to the outside of the drum 2; rather, the scoops can also be arranged towards the inside of the drum 2, their base together with the remaining areas of the actual shell of the drum 2 forming a wall impermeable to the treatment liquor, so that the treatment liquor can in turn be scooped out of the sump 5 in the manner described and can be taken along during the rotation of the drum 2 until it emerges from the scoops 3 after the rotation vertex has been exceeded.

Selbstverständlich können ergänzend Einrichtungen zur thermischen Konditionierung der Behandlungsflotte, wie Vorwärmer, Regler etc., Einrichtungen zur Umwälzung der Behandlungsflotte, wie Umwälzpumpen und dgl., vorgesehen werden. Auch besteht selbstverständlich die Möglichkeit einer unmittelbaren Beheizung des Kessels 1, wie beispielsweise mittels eines nur schematisch angedeuteten Doppelmantelabschnitts 8 in Fig. 1 angedeutet ist.Of course, additional devices for thermal conditioning of the treatment liquor, such as preheaters, controllers, etc., devices for circulating the treatment liquor, such as circulating pumps and the like, can be provided. There is of course also the possibility of direct heating of the boiler 1, as is indicated, for example, by means of a double jacket section 8, which is only indicated schematically in FIG. 1.

Die Ausführungsform der Fig. 2 unterscheidet sich von derjenigen der Fig. 1 dadurch, daß die Behandlungsflotte mittels eines Umwälzsystems 9 vom im unteren Bereich des Inneren des Kessels 1 gelegenen und hier mit 5a bezeichneten Sumpf in einen mit 5b bezeichneten Sumpf im Inneren der Trommel 2 geführt wird. Damit die Behandlungsflotte vom Sumpf 5b den Schöpfgefäßen 3 zuführbar ist, sind im Mantel der Trommel 2 von innen nach außen geführte Durchbrüche 10 vorgesehen. Diese Durchbrüche 10 sind im wesentlichen vom Inneren der Trommel 2 aus gesehen mit Leitblechen 11 ausgestattet, deren Gestaltung sicherstellt, daß zumindest der wesentliche Teil der in den Schöpfgefäßen 3 enthaltenen Behandlungsflotte während des aufwärtsgerichteten Teils der Rotation der Trommel 2 in den Schöpfgefäßen 3 zurückgehalten und erst nach Überschreitung des Scheitelpunkts der Rotation der Trommel 2 freigegeben wird. Hierzu sind die Leitbleche 11 in Rotationsrichtung A um die Durchtrittsöffnungen 10 herumgebogen.The embodiment of FIG. 2 differs from that of FIG. 1 in that the treatment liquor by means of a circulation system 9 from the sump located in the lower region of the interior of the boiler 1 and here designated 5a into a sump designated 5b inside the drum 2 to be led. So that the treatment liquor can be fed from the sump 5b to the scoops 3, openings 10 are provided in the jacket of the drum 2 from the inside to the outside. These openings 10 are essentially seen from the inside of the drum 2 equipped with baffles 11, the design of which ensures that at least the major part of the treatment liquor contained in the scoops 3 is retained in the scoops 3 during the upward part of the rotation of the drum 2 and only after the apex of the rotation of the drum 2 is released. For this purpose, the guide plates 11 are bent around the passage openings 10 in the direction of rotation A.

Des weiteren ist bei diesem zweiten Ausführungsbeispiel das Leitblech 7 ein für Behandlungsflotte undurchlässiges Leitblech, so daß die im Sumpf 5b enthaltene Behandlungsflotte nicht nach unten zum Sumpf 5a herunterfließen kann.Furthermore, in this second embodiment the baffle 7 is a baffle impermeable to the treatment liquor, so that the treatment liquor contained in the sump 5b cannot flow down to the sump 5a.

Bei beiden Ausführungsbeispielen dient im übrigen das Leitblech 7 zum Schutz des Textilguts 4 in seiner abgetafelten Form gegen ßerührung der Trommel 2.In both exemplary embodiments, the guide plate 7 also serves to protect the textile material 4 in its paneled form against the drum 2.

Bei diesem Ausführungsbeispiel kann sogar mit noch kürzerem Flottenverhältnis gearbeitet werden als beim Ausführungsbeispiel der Fig. 1.In this exemplary embodiment, an even shorter liquor ratio can be used than in the exemplary embodiment in FIG. 1.

Beide Ausführungsbeispiele sowie das erfindungsgemäße Verfahren generell eignen sich zur Naßbehandlung von Textilgut sowohl in zusammengelegter Form,also in Strangform, als auch in ausgebreiteter Form, also in flacher Bahnform.Both exemplary embodiments and the method according to the invention are generally suitable for the wet treatment of textile goods both in a collapsed form, that is in a strand form, and in a spread form, that is to say in a flat web form.
