Description

Die Erfindung bezieht sich auf ein Verfahren der dem Oberbegriff des Anspruchs 1 entsprechenden Art und eine entsprechende Anlage.The invention relates to a method of Preamble of claim 1 corresponding type and corresponding facility.

Als "Bemusterung" im Sinne der Erfindung kommt in erster Linie eine farbige Bemusterung in Betracht, wobei nicht nur an eine regelrechte Bebilderung zu denken ist, sondern auch eine Uni-Färbung unter den Begriff fallen soll. Auf die Art des Auftrags des Bemusterungsmittels kommt es für die Erfindung nicht an. In vielen Fällen wird es sich um einen Druckvorgang handeln, doch kommen auch Verfahren in Betracht, bei denen das Bemusterungsmittel auftropfen gelassen wird, aufgegossen wird oder aufgesprüht wird oder bei denen gar die Warenbahn in eine Bemusterungsflotte getaucht wird.As "sampling" in the sense of the invention comes in primarily a colored sample is considered, whereby not just to think of a real illustration, but also fall under the term a plain color should. On the type of application of the sample it does not matter for the invention. In many cases it is a printing process, but also come Consider processes where the sample agent is dripped on, poured on or sprayed on or in which the web is even put into a sampling fleet is dipped.

Die Erfindung befaßt sich mit Verfahren dieser Art, bei denen auf der Warenbahn ein Verdickungsmittel zugegen sein muß. Dies ist in erster Linie bei Druckverfahren der Fall, damit das Bemusterungsmittel nicht verläuft und eine saubere Kontur entsteht oder damit das Bemusterungsmittel nicht zu schnell in Tiefe des textilen Materials eindringt. Die Verwendung von Verdickungsmitteln beim Textildruck ist in dem Buch von M. Peter und H.K. Rouette "Grundlagen der Textilveredlung" 13. Auflage (1989), Seiten 620 bis 623 beschrieben und eine Reihe geeigneter Stoffe aufgezählt. Es versteht sich, daß als Verdickungsmittel auch Mischungen mehrerer entsprechender Stoffe anzusehen sind.The invention is concerned with methods of this type, where a thickener is present on the web have to be. This is primarily in the case of printing processes Case so that the sample does not run and one clean contour is created, or with it the patterning agent does not penetrate too deeply into the textile material. The use of thickeners in textile printing is in the book by M. Peter and H.K. Rouette "Basics of textile finishing" 13th edition (1989), pages 620 to 623 and a number of suitable Listed substances. It is understood that as a thickener also mixtures of several corresponding substances are to be seen.

Beim Druck befindet sich die Verdickung in dem aufgetragenen Medium, d.h. der Druckpaste. Dies gilt auch, wenn bei der Teppichfärberei mit Verdickung gearbeitet werden muß, damit das aufgetragene Bemusterungsmittel nicht zu rasch in den bei Teppichen recht hohen Flor einsinkt und die Spitzen der Fasern nicht genügend Farbstoff erhalten, so daß ein Grauschleier entsteht. Die der Färbeflotte in diesen Fällen zugesetzte Verdickung hält die Flotte lang genug auch an den oberen Bereichen der Fasern fest.When printing, the thickening is in the applied Medium, i.e. the printing paste. This also applies if in carpet dyeing work with thickening must, so that the applied sample does not increase quickly sinks into the very high pile of carpets and the tips of the fibers do not receive enough dye, so that a gray veil is created. The dyeing fleet in Thickening added to these cases keeps the liquor long enough even on the upper areas of the fibers.

Es gibt aber auch Fälle, bei denen Verdickungsmittel nicht mit dem Bemusterungsmittel zusammen, sondern vorher aufgetragen wird. Ein Beispiel hierfür ist der DE 27 08 000 Al zu entnehmen, bei der das Verdickungsmittel (Gum) als Farbrückhaltemittel dient und in einer Schicht auf eine Teppichbahn aufgetragen wird, auf die anschließend ein rapportloses Muster durch Farbflotten aufgetröpfelt wird. Auch hier sind jedoch, wenn die Bemusterung beendet ist und die Ware sich im Dämpfer befindet, Verdickungsmittel zugegeben.But there are also cases where thickeners not together with the sample agent, but beforehand is applied. An example of this is DE 27 08 000 Al in which the thickener (gum) serves as a color retention agent and in one layer a carpet sheet is applied, on which subsequently a repeatless pattern dripped on by fleets of color becomes. Again, however, are when the sampling ends and the goods are in the damper, thickener admitted.

Diese Verdickungsmittel müssen von der Warenbahn nach dem Dämpfen wieder entfernt werden. Diese Aufgabe ist schwierig und erfordert einen erheblichen Waschaufwand. Viele Versuche sind unternommen worden, um das Entfernen der Verdickungsmittel zu erleichtern. Beispielsweise ist die Verdickung erst angefeuchtet worden, worauf sie eine Verweilstrecke durchlief, um die Verdickung durch die Feuchtigkeit quellen zu lassen. Danach sollte sie sich leichter auswaschen lassen.These thickeners have to be removed from the web be removed again after steaming. This task is difficult and requires a lot of washing. Many attempts have been made to remove it to facilitate the thickening agent. For example the thickening has only been moistened, after which it Dwelled through the thickening through the To let moisture swell. After that, she should wash out more easily.

In jedem Fall war bisher der Waschaufwand zur Entfernung der Verdickung wesentlich größer als in der normalen Färberei, wo keine Verdickungsmittel notwendig sind.In any case, the washing effort for removal was previously the thickening much larger than in the normal Dyeing where no thickeners are necessary.

Die Verdickungsmittel bilden am Ende des Dämpfers eine regelrechte Schicht auf der Bahn, und es ist auch bereits unternommen worden, diese Schicht im Endbereich des Dämpfers mechanisch durch Rakeln zu entfernen, so daß wenigstens ein wesentlicher Teil der Verdickungsmittel schon ohne Waschvorgang von der Warenbahn herunter war und der Waschvorgang entsprechend entlastet wurde (DE-OS 34 40 948).The thickeners form at the end of the damper a real shift on the web, and it is too already been done this layer in the end area to remove the damper mechanically by squeegee, so that at least a substantial part of the thickeners was already off the web without washing and the washing process was relieved accordingly (DE-OS 34 40 948).

Alle diese bekannten Maßnahmen standen aber unter dem Aspekt lediglich der Entfernung der Verdickungsmittel, die anschließend aufwendig entsorgt werden mußten.All of these known measures were under the Aspect only of the removal of the thickeners then had to be disposed of at great expense.

Ein Schritt weiter wird in der US-A-4 418 433 getan, die eine Anlage zum kontinuierlichen Färben von Teppichen zeigt. Dieser Stand der Technik liegt dem Oberbegriff des Anspruchs 1 zugrunde. Das Verdickungsmittel wird hierbei nicht nur entfernt, sondern zur erneuten Verwendung wiedergewonnen. Die Entfernung geschieht durch Absaugen am Ausgang des Dämpfers, wo also die Farbe schon auf die Fasern aufgezogen ist. Das abgesaugte Verdickungsmittel wird filtriert und zur Wiedergewinnung der Wärme durch einen Wärmetauscher geschickt. Das so behandelte Verdikkungsmittel wird erneut der vor der Auftragseinrichtung für die Färbeflotte angeordneten Auftragseinrichtung für das Verdickungsmittel zugeleitet.A step further is done in US-A-4,418,433 the one system for the continuous dyeing of carpets shows. This prior art is the generic term of Claim 1 based. The thickener is used not just removed, but recovered for reuse. The removal is done by suction on Exit of the damper, where the color is already on the Fibers is drawn. The extracted thickener is filtered and used to recover the heat sent a heat exchanger. The thickener treated in this way will again be the one in front of the order setup application device arranged for the dyeing liquor for the thickener supplied.

Das Gewicht liegt hierbei also nicht auf der bloßen Entfernung der Verdickung, sondern auf ihrer Wiedergewinnung und im erneuten Einsatz beim Ansatz weiteren Bemusterungsmittels. Die Verfahrensweise hat also sowohl einen ökologischen Aspekt, insofern durch die mehrmalige Verwendung der Verdickungsmittel der Entsorgungsaufwand wesentlich reduziert wird, als auch einen wirtschaftlichen Aspekt, insofern die Mehrfachverwendung der teuren Verdickungsmittel eine Kostenersparnis ergibt, die die Kosten der zusätzlichen apparativen Ausrüstung in relativ kurzer Zeit amortisiert.The weight is not just bare Removal of the thickening, but on their recovery and when used again when adding additional sample agents. So the procedure has both ecological aspect, in so far as it is used several times the thickening agent the disposal effort significantly is reduced as well as an economic Aspect, in so far as the multiple use of the expensive thickeners a cost saving that results in the cost the additional equipment in a relatively short time Amortized time.

Es ist zwar so, daß bei vielen farblichen Bemusterungen, also Färbungen, die in dem Bemusterungsmittel enthaltenen Farbstoffe bei dosiertem Flottenauftrag zu 99 % und mehr auf die Fasern aufziehen und schon von daher die ganz überwiegend aus dem verbliebenen Verdickungsmittel bestehenden Mittelreste fast farblos übrigbleiben. Da aber diese Farbstoffreste sich bei der Mehrfachverwendung der Verdickungsmittel anreichern können, kann das Verdickungsmittel eine Eigenfarbe bekommen, die sich störend auswirken kann.It is true that with many color samples, that is, dyeings contained in the sample agent Dyes with dosed fleet application to 99% and more on the fibers and therefore the whole consisting mainly of the remaining thickener Middle remnants remain almost colorless. Here but these dye residues are found in the multiple use of Thickeners can accumulate, the thickener get their own color that has a disruptive effect can.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße mit Verdickungsmitteln arbeitende Bemusterungsverfahren zu verbessern.The invention has for its object the generic Sample procedures using thickeners to improve.

Diese Aufgabe wird durch die in den Ansprüchen 1 und 3 in ihrem verfahrensmäßigen bzw. apparativen Aspekt wiedergegebene Erfindung gelöst.This object is achieved by the in claims 1 and 3 reproduced in its procedural or apparatus aspect Invention solved.

Als "Mittelreste" im Sinne der Erfindung soll die Gesamtheit der ungebundenen auf der Warenbahn und ihren Fasern befindlichen Stoffe verstanden werden, also nicht nur die Reste des aufgetragenen Bemusterungsmittels, sondern auch die verbliebenen Reste von in vorangegangenen Behandlungsschritten aufgetragenen Behandlungsmitteln wie Schlichte, Avivagen und ähnliches, die den Fasern anhaften. Bei der mechanischen Entfernung der Mittelreste werden diese Anteile weniger erfaßt. Sie verbleiben überwiegend auf der Warenbahn und werden erst beim nachfolgenden Waschvorgang entfernt. Die mechanisch entfernbaren Anteile beinhalten vielmehr vorwiegend die Reste des Bemusterungsmittels, z.B. der Druckpaste, die ganz überwiegend aus dem Verdickungsmittel bestehen, welches auf diese Weise von den unerwünschten Behandlungsmitteln wie Schlichten, Avivagen usw. separierbar ist.As "middle remnants" in the sense of the invention, the Whole of the unbound on the web and their Fibers are understood, so not only the remains of the applied sample agent, but also the remains of the previous ones Treatment steps applied treatment agents such as Sizes, finishing agents and the like that adhere to the fibers. When mechanically removing the middle remnants these shares are less covered. Most of them remain on the web and are only at the next Washing process removed. The mechanically removable parts rather mainly contain the remains of the sample agent, e.g. the printing paste, which is predominantly consist of the thickener, which on this Way of unwanted treatment agents like Finishing, finishing agents, etc. can be separated.

Der Anreicherung der Farbe in dem Verdickungsmittel wird erfindungsgemäß durch die Entfärbungsbehandlung entgegengewirkt, bei welcher die mechanisch gereinigten Mittelreste werden mit einer geeigneten Auftragsvorrichtung wie bei einer Färbung auf ein bahnförmiges durchlässiges Flächengebilde aus Textilfasern aufgetragen, die von dem Bemusterungsfarbstoff leicht anfärbbar sind. Das Flächengebilde kann ein Gewebe oder aber auch ein Vlies aus den Textilfasern sein. Die auf dem Flächengebilde befindlichen Mittelreste werden sodann durch das Flächengebilde hindurchgesaugt, wobei die darin noch enthaltenen Farbstoffe bereitwillig auf die Fasern des Flächengebildes übergehen, die ja entsprechend ausgewählt sind. Die in den Mittelresten noch enthaltenen Farbstoffe werden also aus ihnen gewissermaßen "weggefärbt". Es verbleibt praktisch reines Verdickungsmittel, welches wiederverwendet werden kann. Das Flächengebilde wird entweder verworfen oder durch geeignete Verfahren seinerseits entfärbt, um gegebenenfalls wiederverwendbar zu sein.The accumulation of color in the thickener is counteracted according to the invention by the decolorization treatment, where the mechanically cleaned middle remains with a suitable application device like dyeing on a sheet-like permeable Fabric made of textile fibers applied by the Pattern dye are easy to dye. The fabric can be a fabric or a fleece from the Be textile fibers. The ones on the fabric Middle remnants are then sucked through the fabric, the dyes still contained therein willingly transition to the fibers of the fabric, which are selected accordingly. Those in the middle remnants dyes still contained are made from them so to speak "colored away". It remains practically pure Thickener that can be reused. The fabric is either discarded or by appropriate procedures in turn decolorized, if necessary to be reusable.

Ein wichtiger Aspekt der geschilderten Verfahrensweise liegt darin, daß sowohl die Entfernung des Verdikkungsmittels von der Warenbahn als auch seine Reinigung ohne die Zuhilfenahme von Wasser vonstatten gehen, so daß das wiedergewonnene Verdickungsmittel so, wie es ist, und ohne energieaufwendige Entwässerung wiederverwendet werden kann.An important aspect of the procedure described is that both the removal of the thickener from the web as well as its cleaning without the help of water, so that the recovered thickener as it is, and can be reused without energy-consuming drainage can.

Die der Entfärbung vorgeschaltete mechanische Reinigung kann wie im Stand der Technik durch Sieben oder Filtern erfolgen, wobei die bei der mechanischen Entfernung der Mittelreste mitgenommenen Verunreinigungen wie Flusen und dergleichen aus dem Material entfernt werden.The mechanical cleaning preceding the decolorization can, as in the prior art, by sieving or filtering be done with the mechanical removal the middle remnants of contaminants such as fluff and the like are removed from the material.

Die Ansprüche 3 bis 8 geben die Erfindung in ihrer apparativen Ausgestaltung wieder.Claims 3 to 8 give the invention in its apparatus design again.

  • Die in Fig. 1 mit 1 bezeichnete textile Warenbahn ist in dem Ausführungsbeispiel eine Teppichbahn, die an einer der Darstellung vorgeschalteten Stelle mit einem Auftrag eines Bemusterungsmittels versehen worden ist, welches Verdickungsmittel enthielt. In dem Ausführungsbeispiel handelt es sich um eine verdickte Druckpaste.The textile fabric web designated 1 in FIG. 1 is in the exemplary embodiment, a carpet web, which on a the representation upstream with an order a patterning agent has been provided, which Contained thickener. In the embodiment it is a thickened printing paste.

    Nach dem Auftrag des Bemusterungsmittels sind also auf der Warenbahn 1 das Bemusterungsmittel und das Verdickungsmittel zugleich zugegeben. Die Warenbahn 1 läuft so im Sinne des Pfeiles 2 in einen Dämpfer 3 ein, in welchem die Farbstoffe aus dem Bemusterungsmittel auf die Fasern der Warenbahn 1 aufziehen. Am Ende des Durchlaufs ist dieser Vorgang beendet und bleibt auf der Warenbahn ein Mittelrest zurück, der aus geringen Farbstoffresten, etwaigen geringen Rückständen sonstiger Art und dem gesamten Verdickungsmittel besteht. Letzteres findet sich als eine Art Schicht auf der Polseite der Warenbahn, wenn diese dabei ist, den Dämpfer 3 an dem Auslaß 4 zu verlassen. In dem Dämpfer 3 ist in diesem Bereich eine Rakel 5 vorgesehen, die die Warenbahn 1 abrakelt und einen wesentlichen Anteil des auf der Warenbahn 1 befindlichen Mittelrestes, beispielsweise 50 bis 70 %, von der Warenbahn mechanisch abnimmt und in einer Rinne 6 sammelt, von wo er in einen Pufferbehälter 7 am Auslaß 4 des Dämpfers übergeht. Die Rakel oder eine sonstige mechanische Entfernungseinrichtung können auch außerhalb des Dämpfers dicht am Auslaß 4 angeordnet sein.So after applying the sample agent on the material web 1 the patterning agent and the thickening agent admitted at the same time. The web 1 runs like this in the direction of arrow 2 in a damper 3, in which the dyes from the patterning agent on the fibers of web 1. At the end of the run is this process ends and remains on the web Middle residue back, that of small dye residues, any small residues of any other kind and the whole There is a thickener. The latter is found as one Kind of layer on the pole side of the web, if this is about to leave the damper 3 at the outlet 4. In the damper 3 is provided with a doctor blade 5 in this area, which unscrews the web 1 and an essential Proportion of the middle remainder on goods web 1, for example 50 to 70% of the web mechanically decreases and collects in a gutter 6, from where it enters one Buffer tank 7 at outlet 4 of the damper merges. The Squeegee or other mechanical removal device can also outside the damper close to the outlet 4th be arranged.

    Es ist nicht erwünscht, den auf der Warenbahn verbliebenen Mittelrest durchgreifend zu entfernen. In dem Mittelrest sind nämlich auch Rest von Schlichte, Avivagen und dergleichen enthalten, die an der Faser und weniger im Bereich der oben auf dem Pol befindlichen Verdickungsmittelschicht sitzen. Diese Anteile des Mittelrestes verbleiben bei der Abrakelung überwiegend auf der Warenbahn 1 und gelangen nicht in den Pufferbehälter 7 mit dem abgerakelten Anteil des Mittelrestes. Die unerwünschten Bestandteile wie Schlichte, Avivagen und dergleichen werden ausgewaschen, wenn die Warenbahn 1 nach dem Verlassen des Dämpfers 3 an dem Auslaß 4 im Sinne des Pfeiles 8 in eine nicht dargestellte Waschanlage überführt wird.It is not desirable to leave the one remaining on the web To completely remove the middle remainder. By doing Middle remnants are also the remnants of sizing, finishing agents and the like contained on the fiber and less in Area of the thickener layer on top of the pole to sit. These portions of the middle remainder remain when scraping off predominantly on web 1 and do not get into the buffer container 7 with the doctored Share of the middle remainder. The unwanted ingredients like sizing, finishing agents and the like are washed out, if the web 1 after leaving the Damper 3 at the outlet 4 in the direction of arrow 8 in a washing system, not shown, is transferred.

    Der abgerakelte Mittelrest aus dem Pufferbehälter 7 wird mittels einer Pumpe 9 in eine als Ganzes mit 10 bezeichnete Reinigungseinrichtung überführt. Die Reinigungseinrichtung 10 umfaßt zwei Aggregate 11 und 12. Der abgerakelte Mittelrest gelangt zunächst in das Aggregat 11, welches eine Sieb- und Filtereinheit zum Entfernen von mechanischen Verunreinigungen wie Flusen und dergleichen ist, die beim Abrakeln von der Warenbahn 1 abgenommen werden.The scraped off middle residue from the buffer container 7 is by means of a pump 9 in a 10 designated as a whole Cleaning device transferred. The cleaning facility 10 comprises two units 11 and 12. The doctored The middle remainder first reaches unit 11, which is a sieve and filter unit for removing mechanical contaminants such as fluff and the like which is removed from the web 1 when doctoring become.

    Der mechanisch vorgereinigte Mittelrest gelangt sodann in eine Entfärbungseinheit 12, die die geringfügigen Farbstoffanteile, die in dem Dämpfer 3 nicht auf die Warenbahn 1 aufgezogen, sondern in dem Mittelrest verblieben sind, aus diesem herausholt. Die Entfärbungseinheit 12 wird anhand von Fig. 2 noch im einzelnen beschrieben. The mechanically pre-cleaned middle residue then arrives into a decolorization unit 12, which the minor Dye shares in the damper 3 not on the web 1 raised, but remained in the middle remnant are getting out of this. The decolorization unit 12 will be described in detail with reference to FIG. 2.

    Das die Entfärbungseinheit 12 in der Leitung 13 verlassende Medium ist nicht mehr als "Mittelrest" anzusprechen, sondern besteht aus praktisch reinem Verdickungsmittel, welches in Vorratsbehälter 14 abgegeben werden kann. An sich wäre nur ein Vorratsbehälter 14 erforderlich. Die Qualität des auf der Leitung 13 anstehenden Verdickungsmittels kann jedoch von Metrage zu Metrage der Warenbahn 1 schwanken. Es empfiehlt sich daher, das Verdickungsmittel bei jeder Metrage separat aufzufangen. Aus diesem Grund sind in dem Ausführungsbeispiel drei Vorratsbehälter 14 vorgesehen, in die das auf der Leitung 13 geförderte Verdickungsmittel wahlweise abgegeben werden kann.The one that leaves the decolorization unit 12 in line 13 Medium can no longer be addressed as a "middle remnant", but consists of practically pure thickener, which are delivered in storage container 14 can. As such, only one reservoir 14 would be required. The quality of the line 13 pending However, thickeners can vary from meter to meter Goods web 1 fluctuate. It is therefore recommended to use the thickener to be collected separately for each meter.

In dem gezeigten Ausführungsbeispiel wird das Flächengebilde von einer Rolle 26 abgewickelt, über eine Tragwalze 27 und ein über die Breite des Flächengebildes 30 wirksames Saugrohr 28 in dem horizontalen Abschnitt 30' geführt und anschließend auf eine Rolle 29 wieder aufgewickelt. Der Mittelrest wird durch das Zuführrohr 25 an einer Stelle auf die Oberseite des Flächengebildes 30 abgegeben, an der dieses auf der Rückseite durch eine Gleitplatte 31 unterstützt ist. Durch eine auf der Oberseite angeordnete Streichrakel 32 wird die aufgebrachte Mittelrestmenge zu einer gleichmäßigen Schicht 33 ausgestrichen, die beim Passieren der Eingangsöffnung des Saugrohrs 28 durch das Flächengebilde 30 hindurch in das Saugrohr 28 hineingesaugt wird.In Fig. 2 is a decolorization unit in question 12 reproduced. The sieve and filter unit 11 The remaining medium amount is fed via a feed pipe 25 onto a horizontally guided section 30 'of a web-shaped Fabric 30 abandoned, which is a fabric, represents a knitted fabric or a nonwoven made of fibers, the of those contained in the patterning agent for the carpet Dyes are particularly easy to dye. By doing The embodiment shown is the fabric of a roll 26 unwound, via a support roller 27 and a effective suction pipe over the width of the fabric 30 28 out in the horizontal section 30 'and then wound up on a roll 29 again. The middle remnant is through the feed pipe 25 at one point on top of the fabric 30 delivered on which this the back is supported by a sliding plate 31. By means of a doctor blade 32 arranged on the upper side the medium residue applied becomes a uniform one Layer 33 streaked when passing the entrance opening of the suction pipe 28 through the fabric 30 is sucked through into the suction pipe 28.

    Die in dem Mittelrest noch enthaltenen geringen Farbstoffmengen gehen dabei auf das Flächengebilde 30 über, so daß in der Leitung 34 praktisch farbloses Verdickungsmittel herauskommt, welches in dem Abscheider 35 von dem Saugluftstrom getrennt wird, so daß luftfreies Verdikkungsmittel in die Leitung 13 gelangt, aus der es in der im Zusammenhang mit Fig. 1 beschriebenen Weise weiterverarbeitet wird.The small amounts of dye still contained in the middle residue go over to the fabric 30, so that in line 34 practically colorless thickener comes out, which in the separator 35 of the Suction air flow is separated, so that air-free thickener gets into line 13 from which it is in the processed in connection with FIG. 1 further processed becomes.
