Description
Verfahren zum Schwarzfärben von Textilien aus Polyamiden oder Polyolefinen Bei Textilien aus Polyamiden oder Polyolefinen ist das Problem der Schwarzfärbung noch nicht ausreichend gelöst. Auch wenn es gelingt, Fäden oder Textilien mit schwarzen Farbstoffen anzufärben, so haben diese Färbungen im allgemeinen keine ausreichenden Licht- und Reibechtheiten, so daß man nach wie vor gezwungen ist, schwarzgefärbte Fäden durch Zusatz von Ruß vor dem Spinnprozeß, d. h. durch Spinnfärbung, herzustellen.Process for dyeing textiles made of polyamides or polyolefins black The problem with textiles made of polyamides or polyolefins is that they are blackened not yet adequately resolved. Even if it is possible to use threads or textiles with black To color dyes, these colorations are generally insufficient Fastness to light and rubbing, so that one is still forced to use black-colored ones Threads by adding carbon black before the spinning process, d. H. by spin dyeing.
Zu den an sich bekannten Farbstoffen gehören unter anderem die Umsetzungsprodukte des Tetracyanoäthylens. Durch Reaktion des Tetracyanoäthylens mit stickstoffhaltigen Verbindungen, wie Methyl-und Dimethylanilin, erhält man Farbstoffe der Formeln: die zum Anfärben von Polyesterfasern brauchbar sind. Man erreicht mit diesen Farbstoffen pastellfarbene Töne mit guten Lichtechtheiten.The dyes known per se include the reaction products of tetracyanoethylene. The reaction of tetracyanoethylene with nitrogen-containing compounds, such as methyl and dimethyl aniline, gives dyes of the formulas: which are useful for dyeing polyester fibers. With these dyes, pastel-colored tones with good lightfastness can be achieved.
Es wurde nun überraschenderweise gefunden, daß man Schwarzfärbungen auf Textilien aus Polyamiden und Polyoleiinen erhält, wenn man die Textilien in benzolischen Lösungen färbt, welche die Verbindung, die bei der Umsetzung von Tetracyanoäthylen mit Pyrrol in Gegenwart von Schwefel oder Schwefel enthaltenden Verbindungen und Benzol entsteht, enthalten und anschließend einer Behandlung mit Sattdampf unterwirft. It has now been found, surprisingly, that black colorations are possible on textiles made of polyamides and polyoleiines, if you put the textiles in benzene solutions, which stains the compound that is involved in the implementation of tetracyanoethylene with pyrrole in the presence of sulfur or sulfur-containing compounds and Benzene is formed, contained and then subjected to a treatment with saturated steam.
Zweckmäßig verwendet man als Farbflotte die Reaktionsmischung, die man bei der Herstellung des Farbstoffs, für die hier kein Schutz beansprucht wird, erhält. Die auf diese Weise bei Polyamid- und Polyolefinfäden bzw. aus diesen hergestellten Textilien erzielbaren Schwarzfärbungen zeichnen sich durch gute Licht- und Reibechtheiten aus. The reaction mixture is expediently used as the dye liquor one in the manufacture of the dye, for which no protection is claimed here, receives. Those produced in this way in the case of polyamide and polyolefin threads or from them Black dyeings that can be achieved with textiles are characterized by good lightfastness and rubbing fastness the end.
Beispiel 1 10 g Tetracyanoäthylen werden unter Bildung eines gelb gefärbten Additionskomplexes in 1 1 wasserfreien Benzols gelöst. Dieser Lösung werden 10 g Schwefelpulver zugesetzt und durch Erhitzen auf 800 C in Lösung gebracht. Anschließend fügt man 4 g Pyrrol zu, wobei sich die Lösung dunkelbraun färbt. In dieser Reaktionslösung wird ein Gewirk aus Polypropylenfäden ohne weitere Vorbehandlung 30 Minuten lang auf 800 C erhitzt. Nach dieser Zeit hat das Gewirk eine dunkelolive Farbe angenommen. Durch eine etwa 30 Minuten währende Behandlung mit Sattdampf von 1250 C tritt eine intensive Schwarzfärbung ein. Man wäscht das Gewirk mit Seife und Aceton. Die weiter unten beschriebenen Echtheitsprüfungen ergeben eine Lichtechtheitsnote von 7 und Reibechtheitsnoten von 3 bis 4 (trocken) und 3 bis 4 (naß). Example 1 10 g of tetracyanoethylene turn yellow with the formation of a yellow colored addition complex dissolved in 1 1 anhydrous benzene. This solution will be 10 g of sulfur powder were added and dissolved by heating to 800.degree. Afterward 4 g of pyrrole are added, the solution turning dark brown. In this reaction solution becomes a knitted fabric made of polypropylene threads for 30 minutes without further pretreatment heated to 800 C. After this time the knitted fabric has taken on a dark olive color. A treatment with saturated steam at 1250 C for about 30 minutes causes a intense blackening. The knitted fabric is washed with soap and acetone. The next Fastness tests described below result in a light fastness rating of 7 and Rubbing fastness grades from 3 to 4 (dry) and 3 to 4 (wet).
Beispiel 2 In einer entsprechend dem Beispiel 1 hergestellten Farbflotte wird ein aus Polyamidfäden bestehendes Gewirk gefärbt und anschließend einer Sattdampfbehandlung unterworfen. Echtheitsprüfungen, die nach dem Waschen durchgeführt werden, ergeben eine Lichtechtheitsnote von 6 und Reibechtheiten von 4 (trocken) und 3 (naß). Example 2 In a dye liquor prepared according to Example 1 a knitted fabric made of polyamide threads is dyed and then subjected to saturated steam treatment subject. Authenticity tests carried out after washing reveal a light fastness rating of 6 and rub fastnesses of 4 (dry) and 3 (wet).
Die Licht- und Reibechtheitsprüfungen wurden durchgeführt entsprechend den Angaben der DIN-Normen 54003 bzw. 54021. The light and rub fastness tests were carried out accordingly the information in DIN standards 54003 and 54021.
