Description

Die Erfindung betrifft ein Verfahren zur Beseitigung der Bugmarkierung bei Maschenware in Schlauchform während der kontinuierlichen Einfärbung und anschließenden Fixierung der aufgebrachten Farbstoffe, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for eliminating the bow marking of knitted goods in tubular form during the continuous dyeing and subsequent fixing of the dyes applied, and a device for carrying out the method.

Kontinuierliches Färben von Maschenware in Schlauchform (auch Schlauchware genannt), bestehend aus natürlichen und/oder synthetischen Fasern, erfolgt durch Imprägnieren der Schlauchware mit einer Pigmentsuspension oder Farbstofflösung und anschließendem Fixieren der Farbstoffe mit Dampf und nachfolgender Fertigstellung der Färbung.Continuous dyeing of tubular fabric (also called tubular fabric), consisting of natural and / or synthetic fibers, is carried out by impregnating the tubular fabric with a pigment suspension or dye solution and then fixing the dyes with steam and then completing the dyeing.

Bei dieser Arbeitsweise war es bisher nicht zu vermeiden, daß die beim Foulardieren entstehende Bugmarkierung auch nach dem Fixieren der Farbstoffe sichtbar blieb. So wird in der Zeitschrift "Melliand Textilberichte" 2/1984, auf den Seiten 119 und 120 in einem Artikel von Prof. Dr. Senner darauf hingewiesen, daß trotz einschlägiger Erfahrung der Schlauchwarenfärberpioniere und trotz mannigfaltiger Verfahren und Apparaturen, die bugmarkierungsfreie Arbeitsweise bei der kontinuierlichen Färbetechnik für Maschenware in Schlauchform offensichtlich nicht zu verwirklichen ist.With this method of working, it has previously not been possible to avoid the fact that the bow marking formed during padding remained visible even after the dyes had been fixed. For example, in the magazine "Melliand Textilberichte" 2/1984, on pages 119 and 120 in an article by Prof. Dr. Senner pointed out that despite the relevant experience of the tubular fabric dye pioneers and in spite of various processes and apparatuses, the bug marking-free method of working with the continuous dyeing technique for knitted fabric in tubular form is obviously not feasible.

Des weiteren kann auch mit dem aufwendigen Verlegegerät für das Verlegen von Bruchfalten in schlauchförmigem Textilgut - wie in der Patentschrift 32 40 406 dargelegt - eine Bugmarkierung nicht in jedem Fall vermieden werden.Furthermore, with the complex laying device for laying fold folds in tubular textile material - as stated in the patent specification 32 40 406 - a bug marking cannot be avoided in every case.

Es stellte sich daher die Aufgabe, mittels eines einfachen und wirtschaftlichen Verfahrens zu gewährleisten, daß beim Färben von Maschenware in Schlauchform die Bugmarkierung absolut vermieden wird.It was therefore the task of using a simple and economical method to ensure that the bow marking is absolutely avoided when dyeing knitted fabrics in tubular form.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Maschenware während des Fixierens der aufgebrachten Farbstoffe mindestens einmal mittels Wasserdampf ballonförmig aufgeblasen und wieder flachgelegt wird.This object is achieved in that the knitted fabric is inflated at least once by means of water vapor during the fixing of the applied dyes and laid flat again.

Weitere Merkmale des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Further features of the method according to the invention are the subject of the dependent claims.

Es wurde nämlich gefunden, daß man Färbungen ohne Bugmarkierungen erhält, wenn man die Schlauchware nach dem Eintritt in das Fixiergerät (auch Dämpfer genannt) durch Wasserdampf oder Stickstoff oder ein anderes inertes Gas, ausströmend aus Düsen, aufbläst. Durch das Aufblasen öffnet sich die Schlauchware zu einem Ballon, so daß die Farbstoffixierung unter absolut gleichmäßigen technologischen Bedingungen erfolgen kann. Durch diese Arbeitsweise kann die beim Klotzen mit Farbstoffflotte mehr oder weniger entstehende Bugmarkierung ausgeglichen werden.It has been found that dyeings without bow markings are obtained if the tubular fabric is immersed in water or nitrogen or another inert gas after it has entered the fixing device (also called a damper) gas escaping from nozzles inflates. When inflated, the tubular fabric opens into a balloon, so that the dye fixation can take place under absolutely uniform technological conditions. This way of working can compensate for the more or less emerging bow marking when padding with dye liquor.

Ein Ausführungsbeispiel der Erfindung mit den wesentlichen erfinderischen Merkmalen ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die Zeichnung veranschaulicht das Prinzip des Verfahrens und der Vorrichtung.An embodiment of the invention with the essential inventive features is shown in the drawing and will be described in more detail below. The drawing illustrates the principle of the method and the device.

Hierbei kann als allgemein bekannt angesehen werden, daß die unbehandelte (rohe) oder vorbehandelte Schlauchware S in einem Tauchtrog 1 mit möglichst kleinem Flottenvolumen mit Farbstoffflotte getränkt wird. Dabei ist es entscheidend, den Netzvorgang durch eine mechanische Einrichtung - beispielsweise eine Unterflottenquetsche - zu unterstützen. Durch diese Maßnahme kann die Bugmarkierung beim Farbstoffklotz deutlich verringert werden. Nach dem Tränken mit der Farbstoffflotte wird die Schlauchware mit Preßluft aufgeblasen 2 und nachfolgend mittels eines Quetschwerks abgequetscht 3. Der Belag der Quetschwalzen hat eine Härte zwischen 30 und 70° shore, die Flottenaufnahme liegt zwischen 60 und 150 Prozent, bezogen auf das Trockengewicht der Schlauchware. Nach dem definierten Abquetschen wird die Schlauchware in den Dämpfer 4 eingeführt und in mindestens einem Tauchtrog 5 mit den Fixierchemikalien und Hilfsmitteln imprägniert. Erfindungsgemäß wird nun die jeweils nach dem Passieren eines Tauchtrogs mit Flottenüberschuß beladene Ware mittels aus einer Düse 6, vorzugsweise aus mehreren parallel angeordneten Düsen 6, ausströmenden Dampfes aufgeblasen 7, wobei erfindungsgemäß die ansonsten ohne Aufblasung entstehende Bugmarkierung ausgeglichen wird. Anstatt Dampf kann auch Stickstoff oder ein inertes Gas verwendet werden. Beim Austreten der Schlauchware aus dem Dämpfer wird die Schlauchware in bekannter Weise durch eine mit Frischwasser beladene Einrichtung 8 geführt, auf 50 - 20°C abgekühlt und der nicht auf den Fasern fixierte Farbstoff teilweise entfernt. Danach wird die Schlauchware vor dem Entwässerungsquetschwerk 10 wieder aufgeblasen 9, um Faltenbildung zu vermeiden. Anschließend wird die Schlauchware in bekannter Weise weiterbehandelt. Bei dem erfindungsgemäßen Verfahren ist es sinnvoll, den ersten Tauchtrog 5 beim Eintritt der Schlauchware in den Dämpfer und die Einrichtung 8 jeweils als Wasserschloß auszuführen, um das Fixiergerät luftdicht abzuschließen.It can be regarded as generally known that the untreated (raw) or pretreated tubular fabric S is soaked with dye liquor in an immersion trough 1 with the smallest possible liquor volume. It is crucial to support the wetting process with a mechanical device, such as a sub-squeeze. This measure significantly reduces the bow marking on the dye block. After soaking with the dye liquor, the tubular goods are inflated with compressed air 2 and then squeezed off using a squeeze mechanism 3. The coating of the squeeze rollers has a hardness between 30 and 70 ° shore, the liquor absorption is between 60 and 150 percent, based on the dry weight of the tubular goods . After the defined squeezing, the tubular goods are introduced into the damper 4 and impregnated with the fixing chemicals and auxiliaries in at least one immersion trough 5. According to the invention, the goods loaded with excess liquor after each passing a diving trough are then inflated 7 by means of steam flowing out of a nozzle 6, preferably from a plurality of nozzles 6 arranged in parallel, the bow marking which otherwise occurs without inflation being compensated for according to the invention. Instead of steam, nitrogen or an inert gas can also be used. When the tubular fabric emerges from the damper, the tubular fabric is passed in a known manner through a device 8 loaded with fresh water, cooled to 50-20 ° C. and the dye not fixed on the fibers is partially removed. The tubular fabric is then inflated 9 again in front of the dewatering squeeze unit 10 in order to avoid wrinkling. The tubular fabric is then further processed in a known manner. In the method according to the invention, it makes sense to design the first immersion trough 5 when the tubular goods enter the damper and the device 8 as a water lock in order to seal the fixing device in an airtight manner.

Die Flottenaufnahme beträgt 85 %. Die Ware wird nunmehr in einen Dämpfer mit luftfreier Sattdampfatmosphäre eingefahren. In dem Dämpfer befinden sich zwei Tauchtröge mit einer Chemikalienflotte, die 100 Teile Soda calc., 1 Teil eines Dispergiermittels auf Basis Naphthalinsulfosäure, 1 Teil eines EDTA-Produktes und 60 Teile Natriumdithionit (Hydrosulfit) in 1000 Teilen Flotte enthält. Jeweils nach dem Verlassen der Tauchtröge wird die Schlauchware mit Dampf aufgeblasen. Die Verweilzeit der Ware im Dämpfer beträgt 30 Sekunden. Durch ein Wasserschloß wird die Ware aus dem Dämpfer geführt und dabei mit Wasser von 35°C gespült, dann abgequetscht und wie üblich oxidiert und geseift. Es resultiert eine satte Rotfärbung ohne Bugmarkierung.A non-pretreated cotton interlock knitwear is padded with an aqueous dye liquor containing 40 parts of C.I. vat red 32, 10 parts of a low-foaming wetting agent and 2 parts of a special dispersant in 1000 parts of liquor. The fleet intake is 85%. The goods are now moved into a damper with an air-free saturated steam atmosphere. In the steamer there are two immersion troughs with a chemical bath containing 100 parts of soda ash, 1 part of a dispersant based on naphthalenesulfonic acid, 1 part of an EDTA product and 60 parts of sodium dithionite (hydrosulfite) in 1000 parts of the bath. After leaving the diving troughs, the tubular goods are inflated with steam. The goods stay in the damper for 30 seconds. The goods are led out of the steamer through a water lock and rinsed with water at 35 ° C, then squeezed and oxidized and soaped as usual. The result is a rich red color without bow marking.
