KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es wurde die überraschende Beobachtung gemacht, daß' die in der Imidgruppe substituierten Anthrachinonhydroazine (Indanthrene) und ihre Derivate die bemerkenswerte Eigenschaft besitzen, die Faser auch in kalter Küpe kräftig anzufärben, während die nicht substituierten Indanthrene und deren Derivate vornehmlich nur in warmer Küpe (über 500) gute Färberesultate liefern. In manchen Fällen, wie bei dem einfachsten durch Kondensation von i-Amino-2-halogenanthrachinon mit i-Methylamino-2-halogenanthrachinon erhältlichen Methylindanthren, wird die Faser in kalter Küpe sogar bedeutend kräftiger angefärbt als bei den für die nicht substituierten Indanthrenen gebräuchlichen höheren Temperaturen. Das Verfahren ist auch dadurch von hoher technischer Wichtigkeit, daß es nach ihm gelingt, die genannten Indanthrenderivate leicht mit anderen in kalter Küpe färbenden Produkten, wie z. B. Benzoylaminoänthrachinonen, zu kombinieren und so zu äußerst echten Modetönen zu gelangen.The surprising observation was made that 'the anthraquinone hydroazines (indanthrenes) substituted in the imide group and their derivatives have the remarkable property of staining the fiber vigorously even in a cold vat, while the unsubstituted indanthrenes and their derivatives mainly only in a warm vat (over 50 0 ) give good dyeing results. In some cases, such as the simplest methylindanthrene obtainable by condensation of i-amino-2-halogenanthraquinone with i-methylamino-2-halogenanthraquinone, the fiber is dyed significantly more vigorously in a cold vat than at the higher temperatures customary for the unsubstituted indanthrenes . The process is also of great technical importance that it succeeds according to it, the indanthrene derivatives mentioned easily with other products that dye in a cold vat, such as. B. Benzoylaminoanthraquinones to combine and so to arrive at extremely real fashion tones.
Vorschrift für 50 kg Baumwollgarn.Regulation for 50 kg cotton thread.
10 kg Methylindanthren (10 prozentige Paste) werden mit 40 1 Wasser von 40 ° C. angeteigt.10 kg methylindanthrene (10 percent paste) are made into a paste with 40 l of water at 40 ° C.
Dazu fügt man 3I Natronlauge 30° Be. und 20 1 Hydrosulfitlösung 17 ° Be., rührt gut um und läßt etwa 20 Minuten stehen, wobei der Farbstoff in Lösung geht. Diese Lösung gießt man durch ein Sieb in ein Färbbad, das bestellt ist mit 1000 1 kaltem Wasser, dem man 1I1 1 Natronlauge 30 ° Be., 11 Hydrosulfitlösung 17° Be. und 40 kg Kochsalz zugesetzt hat. Man rührt gut um, geht mit dem gut angefeuchteten Garn ein und färbt 3/4 bis 1 Stunde kalt. Sodann wird das Garn herausgenommen, gut abgewunden, an der Luft verhängt, gespült, mit ι bis 2 ecm Schwefelsäure 66° Be. auf ι 1 Wasser abgesäuert, gut gespült und kochend geseift. Man erhält so sehr lebhafte Blaunuancen von großer Echtheit und Egalität. 3 liters of 30 ° Be sodium hydroxide solution are added to this. and 20 1 hydrosulphite solution 17 ° Be., stir well and leave to stand for about 20 minutes, during which the dye goes into solution. This solution is poured through a sieve into a dye bath that is filled with 1000 liters of cold water, to which 1 l of 1 1 sodium hydroxide solution 30 ° Be., 11 hydrosulfite solution 17 ° Be. and added 40 kg of table salt. The mixture is stirred well to, is a well-moistened with the yarn and dyed 3/4 to 1 hour cold. The yarn is then taken out, well unwound, hung in the air, rinsed, with ι to 2 ecm sulfuric acid 66 ° Be. Acidified to ι 1 water, rinsed well and soaped at the boil. This gives you very lively shades of blue with great authenticity and equality.
Wie schon erwähnt, kann der Farbstoff nach diesem Verfahren mit einer großen Anzahl auch in der Kälte färbender Küpenfarbstoffe der Anthrachinonreihe kombiniert werden. Es werden so die mannigfaltigsten Modenuancen von einer großen Echtheit erzielt. Besonders wichtig ist die Egalität der so erhaltenen Mischnuancen. Das neue Verfahren bedeutet somit einen erheblichen technischen Fortschritt, da blaue, kalt färbende Küpenfarbstoffe von solcher Kombinationsfähigkeit bisher überhaupt nicht bekannt waren.As already mentioned, the dye can be produced in a large number by this method can also be combined in the cold-colored vat dyes of the anthraquinone series. The most diverse fashion nuances of great authenticity are achieved in this way. The evenness of the mixed shades obtained in this way is particularly important. The new procedure thus means a considerable technical advance, as blue, cold-staining vat dyes of such a combination ability were not previously known at all.
Ganz analog verhalten sich die anderen in der Imidgruppe alkylierten Indanthrene und deren Derivate.The other indanthrenes and alkylated in the imide group behave quite analogously their derivatives.
