Definitions
- the invention relates to a method for uniformly dyeing a bundle of filaments consisting of a plurality of filaments with a dye solution during the continuous dyeing of the filament bundle, and to an apparatus for carrying out the method.
- the process described above is used for the uniform finishing or dyeing of artificial and synthetic filament bundles, for example polyacrylic filaments, during their production in the wet spinning process.
- This object is achieved in that the filament bundle is opened in the horizontal and vertical directions during the dyeing by means of a driven roller with a sawtooth-shaped thread profile.
- the filament bundle F is dyed in a conventional manner in a dyeing tub 1, equipped with two deflection rollers 2, with a dye solution 3 stored in the dyeing tub.
- a driven roller 4 equipped with a special sawtooth-shaped thread profile 5 which engages in the filament bundle, the same is divided into many narrow ribbons.
- the tips of the thread profile reach into the filament bundle, and the special design of the thread profile - at an angle to the roller axis - means that the location of the division into the narrow ribbons is continuously shifted laterally (horizontally). This has the effect that even the finest filament bundles are washed several times by the dye solution as they pass through the dyeing tub and thereby absorb dye evenly.
- the fine filament bundles are forced by the lateral migration of the thread profile to migrate up over the oblique side of the sawtooth-shaped thread profile and then fall back into the thread base via the tip. Due to the constant repetition of this process, the filament bundles are vibrated in the vertical direction, which continues up to the deflection rollers. This intensifies the intensive contact between the individual filament and the dye solution, which contributes to increasing the uniformity of the color.
- the thread profile in the dye solution acts like a screw conveyor and ensures thorough mixing of the dye solution in the transverse direction of the dyeing tub. This ensures the supply of dye solution that has not yet been depleted, and additionally increases the uniformity of the coloring of the individual filament bundles.
- the sawtooth-shaped thread profile can engage both from above and from below in the filament bundle.
- the advantages achieved by the invention are in particular in the refinement of artificial and synthetic filaments during their manufacture in order to achieve good uniformity in color.
- the method and the device can also be used at other points in the production facilities where intensive material exchange is desired, such as, for example, in washing baths for removing the spinning solvent, when washing out the incompletely fixed dye after dyeing and in baths for applying the spin finish or from other products.

Description
Die Erfindung betrifft ein Verfahren zum gleichmäßigen Färben eines aus einer Vielzahl von Filamenten bestehenden Filamentbundels mit einer Farbstofflösung während der kontinuierlichen Einfärbung des Filamentbündels, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for uniformly dyeing a bundle of filaments consisting of a plurality of filaments with a dye solution during the continuous dyeing of the filament bundle, and to an apparatus for carrying out the method.
Das oben beschriebene Verfahren dient dem gleichmäßigen Veredeln bzw. Färben von künstlichen und synthetischen Filamentbündeln, beispielsweise Polyacrylfilamenten, während ihrer Herstellung im Naßspinnverfahren.The process described above is used for the uniform finishing or dyeing of artificial and synthetic filament bundles, for example polyacrylic filaments, during their production in the wet spinning process.
Es ist bekannt, in Produktionsanlagen Filamente, beispielsweise Polyacrylfilamente, im Gelzustand zu färben. Aufgrund ungünstiger Gegebenheiten im Färbebad ist die Gleichmäßigkeit der Färbung häufig unbefriedigend. Je nach der örtlichen Packungsdichte und Spannung des Filamentbündels - häufig auch Kabel genannt - entstehen im Querschnitt des Filamentbündels heller und dunkel angefärbte Filamente. Trotz intensiver Vermischung bei der späteren Garnherstellung zeigen die daraus hergestellten Textilien eine unruhige Färbung. Trotz Einbau von rotierenden Körpern in der Färbewanne, beispielsweise Haspeln mit am Umfang angebrachten Stäben, mittels deren Periodische Schläge auf das Filamentbündel ausgeführt werden, ist eine gleichmäßige Färbung der einzelnen Filamente nicht möglich.It is known to dye filaments, for example polyacrylic filaments, in the gel state in production plants. Because of the unfavorable conditions in the dye bath, the uniformity of the dyeing is often unsatisfactory. Depending on the local packing density and tension of the filament bundle - often also called cable - the cross section of the filament bundle produces lighter and darker colored filaments. Despite intensive mixing during the subsequent yarn production, the textiles made from it show an unsteady color. In spite of the installation of rotating bodies in the dyeing tub, for example reels with rods attached to the circumference, by means of which periodic blows are carried out on the filament bundle, a uniform coloring of the individual filaments is not possible.
Es stellte sich daher die Aufgabe, ein einfaches Verfahren für eine gleichmäßige Durchdringung des Filamentbündels mit einer Farbstofflösung zu entwickeln, um letztendlich eine gleichmäßige Färbung der entsprechenden Textilien zu erhalten.It was therefore the task of developing a simple process for uniform penetration of the filament bundle with a dye solution in order to ultimately obtain a uniform dyeing of the corresponding textiles.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Filamentbündel während der Einfärbung mittels einer angetriebenen Walze mit sägezahnförmigem Gewindeprofil in horizontaler und vertikaler Richtung geöffnet wird.This object is achieved in that the filament bundle is opened in the horizontal and vertical directions during the dyeing by means of a driven roller with a sawtooth-shaped thread profile.
Weitere Merkmale des erfindungsgemäßen Verfahrens und der Vorrichtung zur Durchführung des Verfahrens sind Gegenstand der Unteransprüche.Further features of the method according to the invention and the device for carrying out the method are the subject of the dependent claims.
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.
Figur 1 zeigt einen Schnitt durch eine handelsübliche Färbewε me.Figur 2 zeigt eine Draufsicht auf eine handelsübliche Färbewanne.
- FIG. 1 shows a section through a commercially available colorant.
- Figure 2 shows a plan view of a commercially available dyeing tub.
Hierbei kann als allgemein bekannt angesehen werden, daß das Filamentbündel F in einer Färbewanne 1, ausgerüstet mit zwei Umlenkrollen 2, mit einer in der Färbewanne lagernden Farbstofflösung 3 auf herkömmliche Art gefärbt wird. Mittels einer angetriebenen Walze 4 ausgerüstet mit einem speziellen sägezahnförmigen Gewindeprofil 5, das in das Filamentbündel eingreift, wird dasselbe in viele schmale Bändchen unterteilt. Die Spitzen des Gewindeprofils greifen dabei in das Filamentbündel, und durch die spezielle Ausbildung des Gewindeprofils - schräg zur Walzenachse - wird der Ort der Teilung in die schmalen Bändchen kontinuierlich seitlich (horizontal) verlagert. Dies bewirkt, daß auch feinste Filamentbündel während ihres Durchlaufs durch die Färbewanne mehrmals von der Farbstofflösung umspült werden und dabei gleichmäßig Farbstoff aufnehmen.It can be regarded as generally known that the filament bundle F is dyed in a conventional manner in a
Des weiteren werden durch die seitliche Wanderung des Gewindeprofils die feinen Filamentbündel nach einer leichten seitlichen Ablenkung gezwungen, über die schräge Seite des sägezahnförmigen Gewindeprofils hochzuwandern, um dann über die Spitze wieder in den Gewindegrund zu fallen. Durch die ständige Wiederholung dieses Vorganges werden die Filamentbündel in vertikaler Richtung in Vibration versetzt, die sich bis zu den Umlenkrollen fortsetzt. Hierbei wird der intensive Kontakt zwischen dem einzelnen Filament und der Farbstofflösung verstärkt, was zur Erhöhung der Gleichmäßigkeit der Färbung beiträgt.Furthermore, after a slight lateral deflection, the fine filament bundles are forced by the lateral migration of the thread profile to migrate up over the oblique side of the sawtooth-shaped thread profile and then fall back into the thread base via the tip. Due to the constant repetition of this process, the filament bundles are vibrated in the vertical direction, which continues up to the deflection rollers. This intensifies the intensive contact between the individual filament and the dye solution, which contributes to increasing the uniformity of the color.
Das in der Farbstofflösung liegende Gewindeprofil wirkt wie eine Förderschnecke und bewirkt eine gute Durchmischung der Farbstofflösung in Querrichtung der Färbewanne. Hierdurch wird die Zuführung von noch nicht verarmter Farbstofflösung gesichert, sowie die Gleichmäßigkeit der Färbung der einzelnen Filamentbündel noch zusätzlich erhöht.The thread profile in the dye solution acts like a screw conveyor and ensures thorough mixing of the dye solution in the transverse direction of the dyeing tub. This ensures the supply of dye solution that has not yet been depleted, and additionally increases the uniformity of the coloring of the individual filament bundles.
Hierbei kann das sägezahnförmige Gewindeprofil sowohl von oben als auch von unten in das Filamentbündel eingreifen.Here, the sawtooth-shaped thread profile can engage both from above and from below in the filament bundle.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere beim Veredeln von künstlichen und synthetischen Filamenten während ihrer Herstellung um gute Gleichmäßigkeit der Färbung zu erreichen.The advantages achieved by the invention are in particular in the refinement of artificial and synthetic filaments during their manufacture in order to achieve good uniformity in color.
Bei der Verarbeitung von dickeren Filamentbündeln mit höheren Metergewichten kann die Gleichmäßigkeit auf einfache Weise durch Veränderung der Walzendrehzahl sowie durch Austausch der Walze gegen eine Walze mit anderem Gewindeprofil (Steigung. Gewindetiefe, Gewindegrund) sichergestellt werden.When processing thicker filament bundles with higher meter weights, uniformity can easily be ensured by changing the roller speed and by exchanging the roller for a roller with a different thread profile (pitch, thread depth, thread root).
Das Verfahren und die Vorrichtung konnen jedoch auch an anderen Stellen der Produktionsanlagen, an welchen ein intensiver Stoffaustaus.;h erwünscht ist wie beispielsweise bei Waschbädern zur Entfernung des Spinnlösungsmittels, beim Auswaschen des nicht vollständig fixierten Farbstoffs nach dem Färben sowie bei Bädern zum Aufbringen der Spinnavivage oder von anderen Produkten vorteilhaft verwendet werden.However, the method and the device can also be used at other points in the production facilities where intensive material exchange is desired, such as, for example, in washing baths for removing the spinning solvent, when washing out the incompletely fixed dye after dyeing and in baths for applying the spin finish or from other products.
