Abstract

Dyeing of fabrics composed of synthetic fibres includes a thermal treatment stage using a fluid at a temp. of 50-100 (60-90) degrees C before dyeing and fixing at 40 degrees C or at room temp.. The process ensures that the fabric is well bulked after treatment. The hot fluid for the warming stage is suitably water, and the fabric is pref. moved mechanically while being warmed. The fabric is pref. heated in two stages, being moved to and fro between each stage. After the fabric has been warmed, water is removed from it to give it a max. water content of 60 (25-50)%. The material is cooled after the water has been extracted. The fabric dwells in the hot water for 15 seconds to 5 minutes, and detergents are added to the hot water.

Description

Verfahren zum Färben von Textilgut Process for dyeing textiles

Die Erfindung betrifft ein Verfahren zum Färben von Textilgut aus synthetischen Fasern, wobei das Textilgut zur Anwendung der Färbeflotte zunächst einer Wärmebehandlung unterworfen und dann so weit abgekühlt wird, daß das anschließende Färben und Fixieren des Farbstoffes bei einer Temperatur unter 400C, vorzugsweise etwa bei Raumtemperatur, erfolgt, gemäß P 24 36 688.9-26. The invention relates to a method for dyeing textile goods synthetic fibers, the textile material for the application of the dye liquor first subjected to a heat treatment and then cooled so far that the subsequent Dyeing and fixing of the dye at a temperature below 40 ° C., preferably at about room temperature, according to P 24 36 688.9-26.

Beim Färben von Textilgut aus synthetischen Fasern, beispielsweise Polyamid und Polyester, zeigt sich, daß die unvermeidlichen Unterschiede in den Temperatureinwirkungen des vorangegangenen Herstellungsprozesses der Faser und des Garnes zu Unterschieden in der Affinität führen und damit einen unterschiedlichen Fixiergrad bedingen. When dyeing textiles made of synthetic fibers, for example Polyamide and polyester, it turns out that the inevitable differences in the Temperature effects of the previous manufacturing process of the fiber and the Yarn lead to differences in affinity and thus a different one Condition degree of fixation.

Es ist bekannt, diese durch die "Vorgeschichte" bedingten thermischen Unterschiede der Fasern durch Wahl einer genügend hohen Färbetemperatur auszugleichen und auf diese Weise eine gleichmäßige Affinität herzustellen. It is known that this "prehistory" caused thermal Compensate for differences in the fibers by choosing a sufficiently high dyeing temperature and in this way to establish a uniform affinity.

Nachteilig bei diesem Verfahren ist der durch die hohe Färbeflotten- Temperatur bedingte beträchtliche Energieaufwand.The disadvantage of this process is that due to the high dye liquor Considerable expenditure of energy due to temperature.

Gegenstand des Hauptpatents ist ein Verfahren, bei dem das Textilgut zunächst einer Wärmebehandlung im Temperaturbereich zwischen 90 und 1500C unterworfen und dann so weit abgekühlt wird, daß das anschließende Färben und Fixieren des Farbstoffes bei Raumtemperatur erfolgt. Durch die genannte Wärmebehandlung werden die in den Fasern des Textilgutes vorhandenen Spannungen entfernt (die "Vorgeschichte" somit beseitigt); dieser vergleichmäßigte Zustand bleibt auch dann voll erhalten, wenn das Textilgut zwischen der Wärmebehandlung und der Anwendung der Färbeflotte abgekühlt wird. Das Färben und Fixieren des Farbstoffes kann dann bei Raumtemperatur erfolgen, was eine wesentliche Energieersparnis mit sich bringt. The main patent is a process in which the textile initially subjected to a heat treatment in the temperature range between 90 and 1500C and then cooled so far that the subsequent dyeing and fixing of the dye takes place at room temperature. By be the said heat treatment removes the tensions present in the fibers of the textile material (the "prehistory" thus eliminated); this evened-out state remains fully intact when the textile material is between the heat treatment and the use of the dye liquor is cooled. The dyeing and fixing of the dye can then take place at room temperature take place, which brings with it a significant energy saving.

Bei dem im Hauptpatent beschriebenen Ausführungsbeispiel erfolgt die genannte Wärmebehandlung mit Hilfe von heißem Wasserdampf bei einer Temperatur zwischen 90 und 1500C. Ein solches Vordämpfen ergibt in vielen Fällen eine hervorragende Warenqualität. In the embodiment described in the main patent takes place said heat treatment with the aid of hot steam at one temperature between 90 and 1500C. Such pre-steaming results in excellent quality in many cases Quality of goods.

Der Erfindung liegt nun die Aufgabe zugrunde, das Verfahren gemäß dem Hauptpatent dahin weiterzuentwickeln, daß sich eine besonders gute Bauschentwicklung des Textllgutes ergibt. The invention is based on the object, the method according to to further develop the main patent in such a way that a particularly good bulk development of the textual goods results.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Wärmebehandlung mittels einer Flotte im Temperaturbereich zwischen 50 und 1000C, vorzugsweise zwischen 60 und 950C, durchgeführt wird. According to the invention, this object is achieved in that the heat treatment by means of a liquor in the temperature range between 50 and 1000C, preferably between 60 and 950C.

Wie umfangreiche Versuche zeigten, ergibt eine solche (vor dem Abkühlen und anschließenden Färben erfolgende) Wärmebehandlung des Textilgutes in einer Flotte, insbesondere in einer wässrigen Flotte unter gleichzeitiger mechanischer Bewegung des Textilgutes in dieser Flotte, eine hervorragende Bauschentwicklung des Textilgutes, die auch dann erhalten bleibt, wenn das Textilgut anschließend abgekühlt und bei niedriger Temperatur, insbesondere bei Raumtemperatur, gefärbt und fixiert wird. As extensive tests have shown, such (before cooling and subsequent dyeing) heat treatment of the textile goods in a liquor, especially in an aqueous liquor with simultaneous mechanical agitation of the textile goods in this liquor, an excellent bulk development of the textile goods, which is also retained when the textile material is subsequently cooled down and with low temperature, in particular at room temperature, colored and is fixed.

Darüber hinaus besitzt diese Wärmebehandlung den bereits erläuterten Egalisiereffekt und kann außerdem eine oft erwünschte Waschwirkung ausüben (z.B. Entfernung der bei der anschließenden Färbung störenden Signierfarbstoffe).In addition, this heat treatment has the one already explained Leveling effect and can also have an often desired washing effect (e.g. Removal of the marking dyes that interfere with the subsequent coloring).

Die Wärmebehandlung erfolgt zweckmäßig in einer wässrigen Flotte, doch ist im Rahmen der Erfindung auch die Verwendung organischer Lösungsmittel möglich. The heat treatment is expediently carried out in an aqueous liquor, however, the use of organic solvents is also possible within the scope of the invention.

Das Textilgut wird nach Wärmebehandlung in der wSssrigen Flotte, vor Zuführung der Färbeflotte zweckmäßig bis auf einen maximalen Wassergehalt von 60%, vorzugsweise von 25 bis 50%, entwässert. Das Abkühlen des Textilgutes erfolgt zur Einsparung von Kühlleistung vorteilhaft im wesentlichen nach dem Entwässern. After heat treatment in the aqueous liquor, the textile material is before adding the dye liquor, expediently up to a maximum water content of 60%, preferably from 25 to 50%, dehydrated. The textile goods are cooled down in order to save cooling capacity, it is advantageous essentially after dewatering.

Die Zeitdauer der Wärmebehandlung des Textilgutes in der Flotte beträgt (Je nach Art des Textilgutes und angewandter Flottentemperatur) zwischen 15 Sekunden und 5 Minuten. The duration of the heat treatment of the textile material in the liquor is (Depending on the type of textile and the liquor temperature used) between 15 seconds and 5 minutes.

Der wässrigen Flotte können Detergentien zugesetzt werden, um die von der wässrigen Flotte zusätzlich ausgeübte Waschwirkung zu verstärken. Detergents can be added to the aqueous liquor in order to To reinforce the washing effect additionally exerted by the aqueous liquor.
