Abstract

1. Process for after-treating fibres which consist of cellulose or contain cellulose and have been dyed or printed with reactive dyestuffs, characterised in that the after-treatment process consists of a sequence of in each case 2-8 alternating aqueous rinsing and liquor-free hot-treatment steps.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Nachbehandeln von mit Reaktivfarbstoffen gefärbten oder bedruckten aus Cellulose bestehenden oder Cellulose enthaltenden Fasern.The present invention relates to a process for the aftertreatment of fibers dyed or printed with reactive dyes consisting of or containing cellulose.

Das neue Verfahren ist dadurch gekennzeichnet, daß der Nachbehandlungsprozeß aus einer Folge abwechselnder Spül-und flottenfreier Heißbehandlungsvorgänge besteht.The new process is characterized in that the aftertreatment process consists of a sequence of alternating rinsing and liquor-free heat treatment processes.

Diese flottenfreie Heißbehandlung der Faser wird vorzugsweise durch Einwirkung von Heißluft und/oder Dampf und/ oder Kontakthitze und/oder Strahlungswärme und/oder Hochfrequenzerhitzung bewirkt.This liquor-free heat treatment of the fiber is preferably brought about by the action of hot air and / or steam and / or contact heat and / or radiant heat and / or high-frequency heating.

Die Faser wird bei dieser flottenfreien Heißbehandlung vorzugsweise Temperaturen von 80 bis 200°C und insbesondere von 90 bis 100°C, während vorzugsweise 0,2 bis 10 Minuten, insbesondere 0,5 bis 2 Minuten, ausgesetzt.In this liquor-free heat treatment, the fiber is preferably exposed to temperatures of 80 to 200 ° C. and in particular of 90 to 100 ° C., preferably for 0.2 to 10 minutes, in particular 0.5 to 2 minutes.

Das Fasermaterial wird im erfindungsgemäßen Verfahren vorzugsweise als textiles Gewebe eingesetzt, es ist jedoch die Faser als solche, z.B. in Form eines Spulgarnes erfindungsgemäß behandelbar. Die Spül- sowie die flottenfreien Heißbehandlungsvorgänge erfolgen vorzugsweise von der Innenseite nach der Außenseite der Faser bzw. des Gewebes.The fiber material is preferably used as a textile fabric in the process according to the invention, but it is the fiber as such, for example in the form of a spool yarn, can be treated according to the invention. The rinsing and the liquor-free heat treatment processes are preferably carried out from the inside to the outside of the fiber or the fabric.

Das Verfahren eignet sich sowohl zum Nachwaschen von Aüsziehfärbungen als auch zum Nachwaschen von Kontinuefärbungen und Drucken.The process is suitable both for washing out stain dyeings and for washing continuous dyeings and prints.

Durch das neue Verfahren ist es überraschenderweise möglich, den zeit- und energieaufwendigen Auswaschprozeß des Farbstoffhydrolysates nach dem Färben oder Bedrucken _unter gleichzeitiger Einsparung von Wasser und Energie wesentlich zu verkürzen.The new process surprisingly makes it possible to significantly shorten the time-consuming and energy-intensive washing-out process of the dye hydrolyzate after dyeing or printing, while at the same time saving water and energy.

Die für die Durchführung des neuen Verfahrens notwendigen technischen Einrichtungen sind hinreichend bekannt und können in bestehende konventionelle Anlagen zum Färben und/oder Nachwaschen leicht eingebaut werden. Es handelt sich um Apparate, die Heißluft und/oder Heißdampf und/ oder Kontakthitze und/oder Infrarotstrahlung und/oder Hochfrequenzstrahlung erzeugen.The technical facilities necessary for the implementation of the new method are well known and can be easily installed in existing conventional dyeing and / or washing facilities. These are devices which generate hot air and / or superheated steam and / or contact heat and / or infrared radiation and / or high-frequency radiation.

Als Cellulose enthaltende Mischfasern kommen beispielsweise in Frage: Cellulose/Polyester-Mischfasern, Cellulose/Polyamid-Mischfasern.Examples of suitable mixed fibers containing cellulose are: cellulose / polyester mixed fibers, cellulose / polyamide mixed fibers.

Vorzugsweise werden jeweils 2 bis 8 spül- und flottenfreie Heißbehandlungsgänge durchgeführt.Preferably 2 to 8 rinse and liquor-free heat treatment cycles are carried out.

Als für das erfindungsgemäße Verfahren geeignete Reaktivfärbungen sind vorzugsweise solche zu nennen, die mindestens einen Halogenchinoxalinyl-, Halogentriazinyl- Halogenpyrimidinyl- und/oder Vinylsulfonylrest aufweisen. Als Reaktivfarbstoffe kommen beispielsweise sulfogruppenhaltige, wasserlösliche, organische Farbstoffe aus der Reihe der Anthrachinon-, Azo-, Azometallkomplex-, Formazan-, Oxazin- und Phthalocyaninreihe in Betracht. Beispielhaft seien die in den Anwendungsbeispielen bezeichneten Reaktivfarbstoffe aufgeführt.The reactive dyeings suitable for the process according to the invention are preferably those which have at least one haloquinoxalinyl, halotriazinyl, halopyrimidinyl and / or vinylsulfonyl radical. Suitable reactive dyes are, for example, sulfo-containing, water-soluble, organic dyes from the series of the anthraquinone, azo, azo metal complex, formazane, oxazine and phthalocyanine series. The reactive dyes specified in the application examples are listed as examples.

Das erfindungsgemäße Verfahren wird im allgemeinen wie folgt durchgeführt:

  • 1. Nachbehandlung von Ausziehfärbungen:
    • Nach Beendigung des Reaktivfärbeprozesses wird die erschöpfte Flotte abgelassen und ein- bis drei l mit frischem Betriebswasser bei Raumtemperatur gespült. Anschließend erfolgt eine abwechselnde direkte Aufheizung des Färbegutes mittels Heißluft, Heißdampf, Kontakthitze, Infrarotstrahlung und/ oder Hochfrequenzstrahlung und jeweils ein Spülstoß mit kaltem oder angewärmten Betriebswasser. Nach jeweils 1 bis 5 derartigen Extraktionsstößen ist die Extraktion des Farbstoffhydrolysates beendet und die gewünschte Echtheit erreicht.
  • 2. Nachbehandlung von gefärbten und/oder bedruckten Warenbahnen:
    • Die gefärbte und/oder bedruckte Warenbahn durchläuft kontinuierlich eine aus mehreren Waschabteilen bestehende Waschstraße, bei welcher zwischen den gegebenenfalls mit Quetschwerken und/oder Siebtrommeln und/oder Spritzrohren versehenen Naßbehandlungskästen Abteile zur Einwirkung von Dampf und/oder Heißluft und/oder IR-Strahlung und/oder Hochfrequenzstrahlung angeordnet sind, die eine rasche Aufheizung der Warenbahn im Einwirkungsbereich ermöglichen, wobei die zur Extraktion des herausdiffundierten Hydrolysates verwendete Waschflotte bevorzugt nach dem Gegenstromprinzip arbeitet. Die Waschflotte kann die zum Nachwaschen von Reaktivfärbungen üblichen Zusätze enthalten. Als solche Zusätze seien beispielsweise aufgeführt:
    • Alkylnaphthalinsulfonate, Mineralölsulfonate, Alkylsulfonate, Fettalkoholsulfate, sulfatierte oxyäthylierte Verbindungen, Fettsäureester von Polyalkoholen, oxyäthylierte Fettalkohole, oxyäthylierte Alkylphenole, oxyäthylierte Alkylnaphthole.
The process according to the invention is generally carried out as follows:
  • 1. Post-treatment of pull-out dyeings:
    • After the reactive dyeing process has ended, the exhausted liquor is drained off and rinsed with fresh process water at room temperature for one to three liters. This is followed by an alternating direct heating of the material to be dyed using hot air, superheated steam, contact heat, infrared radiation and / or high-frequency radiation and a rinse pulse with cold or heated process water. After 1 to 5 such bursts of extraction, the extraction of the dye hydrolyzate is complete and the desired fastness is achieved.
  • 2. Post-treatment of colored and / or printed webs:
    • The dyed and / or printed web continuously runs through a washing line consisting of several washing compartments, in which compartments between the wet treatment boxes, optionally equipped with squeeze mechanisms and / or sieve drums and / or spray pipes, for exposure to steam and / or hot air and / or IR radiation and / or or high-frequency radiation are arranged, which allow rapid heating of the material web in the area of influence, the washing liquor used to extract the hydrolyzate diffused out preferably working according to the countercurrent principle. The wash liquor can contain the additives which are customary for washing reactive dyes. Examples of such additives are:
    • A lkylnaphthalinsulfonate, mineral oil sulfonates, alkyl sulfonates, fatty alcohol sulfates, sulfated oxyethylated compounds, fatty acid esters of polyalcohols, oxyethylated fatty alcohols, oxyethylated alkylphenols, oxyethylated alkylnaphthols.

Die nach dem erfindungsgemäßen Verfahren nachbehandelte Ware zeigt insbesondere bei empfindlichen Qualitäten durch Materialschonung ein verbessertes Warenbild.The product aftertreated by the method according to the invention shows an improved product appearance, particularly in the case of sensitive qualities, by protecting the material.

Der Feuchtegehalt des nachbehandelnden Fasermaterials beträgt während der Nachbehandlung vorzugsweise 30 bis 180 Prozent, bezogen auf das Trockengewicht der Faser. Bei den in den folgenden Beispielen bezeichneten Teilen handelt es sich in allen Fällen um Gewichtsteile.The moisture content of the aftertreatment fiber material during the aftertreatment is preferably 30 to 180 percent, based on the dry weight of the fiber. The parts designated in the following examples are parts by weight in all cases.
