Abstract

The invention relates to a method for impregnating moving textile sheet materials such as woven or knitted materials or the like with treatment fluids for desizing, scouring, bleaching or the like and apparatus for carrying out said method and has the purpose of simplifying the process of impregnating the material with chemicals in order thereby to achieve processing and equipment improvements and savings. According to the invention, it is proposed to this end that the dry or pretreated moist textile materials be introduced into a steam treatment and be impregnated with the treatment fluid, under the conditions of a tight strand of guiding, only after entry into the steam treatment, the steam treatment being continued throughout. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Imprägnieren von laufenden Textilbahnen wie Gewebe-oder Gewirkebahnen oder dergl. mit Behandlungsflüssigkeiten zum Entschlichten, Abkochen, Bleichen oder dergl., sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for impregnating running textile webs such as woven or knitted webs or the like with treatment liquids for desizing, boiling, bleaching or the like, and to an apparatus for carrying out this method.

Es ist bekannt, Textilbahnen in besonderen Imprägniereinrichtungen mit Chemikalien oder dergl. zu tränken und nach dem Abquetschen zur Limitierung der Flottenmenge auf der Ware in einen Dampfer einzuführen, in dem dann die Chemikalien auf die Ware einwirken. Nachdem die Ware zunächst in gebundener Form durch den Dämpfer läuft, wird sie dann in der Regel abgelegt.It is known to impregnate textile webs in special impregnation devices with chemicals or the like and, after squeezing them to limit the amount of liquor on the goods, introduce them into a steamer in which the chemicals then act on the goods. After the goods first run through the damper in bound form, they are then usually put down.

Bei der Ablage bilden sich häufig auf und in der Ware Liegefalten die, wie Untersuchungen ergeben haben, z.B. durch Verformungen der Baumwollfasern oder -fäden oder durch Quellungsunterschiede in der Ware entstehen, da die durch das Quetschwerk begrenzte Flottenmenge auf der Ware nicht ausreicht, um die Fasern geschmeidig zu machen und voll ausquellen zu lassen.During storage, folds often form on and in the goods, which, as studies have shown, e.g. due to deformation of the cotton fibers or threads or due to differences in swelling in the goods, since the amount of liquor on the goods limited by the squeeze mechanism is not sufficient to make the fibers supple and allow them to swell fully.

Es wurde deshalb schon vorgeschlagen, im Dämpfer besondere Flüssigkeitsauftragsbehälter (Booster) anzubringen, in denen die Ware nach dem Aufheizen und einer kurzen Quellzeit erneut mit Flüssigkeit getränkt wird. Dieses Angebot an zusätzlicher Feuchtigkeit reicht dann aus, um die Ware voll ausquellen zu lassen. Nach den bisherigen Erfahrungen kann auf diese Weise die Bildung von Liegefalten weitgehendst vermieden werden.It has therefore already been proposed to install special liquid application containers (boosters) in the damper, in which the goods are soaked again with liquid after heating and a short swelling time. This offer of additional moisture is then sufficient to allow the goods to swell fully. Based on previous experience, the formation of lying folds can be largely avoided in this way.

Ausgehend von diesem Stand der Technik soll durch die Erfindung die Aufgabe gelöst werden, auch den Imprägniervorgang der Ware mit den Chemikalien zu vereinfachen, um so verfahrensmäßige und apparative Verbesserungen und Einsparungen zu erzielen.On the basis of this prior art, the object of the invention is also to simplify the process of impregnating the goods with the chemicals, in order to achieve process and apparatus improvements and savings.

Erfindungsgemäß wird dazu vorgeschlagen, die trockenen oder aus einer Vorbehandlung kommenden feuchten Warenbahnen in eine Dampfbehandlung einzuführen und erst nach dem Eintritt in die Dampfbehandlung bei gebundener Warenführung mit der Behandlungsflüssigkeit zu imprägnieren, wobei die Dampfbehandlung fortgesetzt wird. Weitere Verfahrensmerkmale sind aus den Ansprüchen 2 und 3 zu entnehmen.According to the invention, it is proposed to introduce the dry webs of material or those coming from a pretreatment into a steam treatment and to impregnate them with the treatment liquid only after entering the steam treatment with bound product guidance, the steam treatment being continued. Further process features can be found in claims 2 and 3.

Bei einer Vorrichtung zur Durchführung dieses Verfahrens in einem Dämpfer mit gebundener Führung der Warenbahnen über obere und untere Walzen sollen an einer oder mehreren der unteren Walzen Flüssigkeitsauftragströge mit geringem Flotteninhalt (Booster) angeordnet sein. Weitere kennzeichnende Merkmale der Erfindung sind Gegenstände der Ansprüche 5 bis 7.In a device for carrying out this method in a damper with bound guidance of the material webs over upper and lower rollers, liquid application streams with a low liquor content (booster) should be arranged on one or more of the lower rollers. Further characteristic features of the invention are the subject matter of claims 5 to 7.

Durch die Erfindung kann die Behandlungszeit so wesentlich verkürzt werden, daß auf eine Ablage der Ware in ungebundener Form verzichtet werden kann. Ferner kann das teure externe Imprägnierungsabteil mit dem Quetschwerk eingespart werden und durch den einfachen und billigen Booster im Dämpfer ersetzt werden.Through the invention, the treatment time can be shortened so much that storage of the goods in an unbound form can be dispensed with. Furthermore, the expensive external impregnation compartment can be saved with the squeeze mechanism and replaced by the simple and cheap booster in the damper.

Auf der beiliegenden Zeichnung ist ein normaler Rollerbed-Dämpfer dargestellt in dem an verschiedenen unteren Umlenkwalzen Booster gemäß der Erfindung angeordnet sind.In the accompanying drawing, a normal rollerbed damper is shown in which boosters according to the invention are arranged on various lower deflection rollers.

Der Dämpfer ist in der Darstellung ganz allgemein mit 10 bezeichnet. Durch den Teil des Dämpfers mit der gebundenen Warenführung wird die Warenbahn 11 über obere 12 und untere Walzen 13 geführt. Wie man erkennt, sind an verschiedenen Walzen 13 Booster 14, 15 mit geringem Flüssigkeitsinhalt angebracht. Dabei kann im Booster 14 Behandlungsflüssigkeit hoher Konzentration 16 auf die Warenbahn 11 aufgebracht werden und die Booster 15 können Wasser enthalten, um zusätzliche Feuchtigkeit auf die Ware zu bringen. Die Booster 14 und 15 können aber auch alle mit gleicher Behandlungsflüssigkeit gefüllt sein, so daß nach einer mehrmaligen Imprägnierung mit der Behandlungsflüssigkeit jedesmal wieder eine Dampfbehandlung erfolgt, womit sich der Behandlungsvorgang wesentlich verkürzen läßt.The damper is generally designated 10 in the illustration. Through the part of the damper with the bound fabric guide, the web 11 is guided over upper 12 and lower rollers 13. As can be seen, 13 boosters 14, 15 with a low liquid content are attached to different rollers. Treatment liquid 16 of high concentration 16 can be applied to the web 11 in the booster 14 and the boosters 15 can contain water in order to bring additional moisture to the goods. The boosters 14 and 15 can, however, also all be filled with the same treatment liquid, so that after repeated impregnation with the treatment liquid, steam treatment takes place each time, so that the treatment process can be shortened considerably.
