KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
In der Patentschrift Nr. 65651 ist gezeigt, dafs gewisse Amidonaphtolsulfosäuren im Stande sind, sich mit zwei Molecülen eines Diazokörpers zu verbinden.In patent specification No. 65651 it is shown that certain amidonaphthol sulfonic acids are able to interact with two molecules of a diazo body connect to.
Es hat sich nun ergeben, dafs auch die Amidonaphtole selbst in analoger Weise primäre Disazofarbstoffe liefern und dafs letztere tiefe, meist schwarze Nuancen zeigen. Ausgehend von dieser Beobachtung wurde ein Verfahren gefunden, um unlösliche schwarze bis braunschwarze Azofarben auf der Faser zu entwickeln. Dasselbe besteht darin, dafs die Faser mit der Lösung des Amidonaphtols in Aetznatron imprägnirt und dann in ein Bad gebracht wird, das einen Ueberschufs einer Diazoverbindung in essigsaurer oder alkalischer Lösung enthält.It has now been found that the amidonaphthols themselves are also primary in an analogous manner Provide disazo dyes and that the latter show deep, mostly black nuances. Outgoing from this observation a process was found to develop insoluble black to brownish black azo colors on the fiber. The same thing consists in the fact that the fiber is mixed with the solution of amidonaphthol in caustic soda impregnated and then placed in a bath containing an excess of a diazo compound contains in acetic acid or alkaline solution.
Zum Beispiel: 1,6 kg Jr-Amidonaphtol des Patentes Nr. 69458 werden mit 0,85 kg Natronlauge (400 B.) in 100 1 Wasser gelöst. Man giebt 5 kg Türkischrothöl hinzu und imprägnirt mit dieser Mischung die zu färbende Baumwolle. Diese wird getrocknet und dann in ein Bad gebracht, das nach folgender Vorschrift bereitet ist.For example: Jr Amidonaphtol 1.6 kg of Patent No. 69458 are dissolved with 0.85 kg of sodium hydroxide (40 0 B.) in 100 1 of water.. 5 kg of Turkish red oil are added and the cotton to be dyed is impregnated with this mixture. This is dried and then placed in a bath that has been prepared according to the following instructions.
2,8 kg p-Nitranilin werden mit 8 1 heifsem Wasser verrührt und dann 5 1 Salzsäure (220 B.) hinzugegeben. Man fügt 20 1 kaltes Wasser hinzu und läfst auf 200 C. abkühlen. Dann werden 1,4 kg Nitrit eingetragen unter gleichzeitigem Zusatz von ca. 20 kg Eis. Nach beendeter Diazotirung neutralisirt man die freie Mineralsäure mit ι ο kg essigsaurem Natron oder 7 kg Soda und bringt das Ganze auf ca. 400 1.2.8 kg of p-nitroaniline are stirred with 8 1 hot water, and then added 5 1 hydrochloric acid (22 0 B.). It adds 20 1 cold water and läfst to 20 0 C. cool. 1.4 kg of nitrite are then introduced with the simultaneous addition of approx. 20 kg of ice. When the diazotization is complete, the free mineral acid is neutralized with ο kg of acetic acid soda or 7 kg of soda, and the whole is brought to about 400 liters.
Wird die mit Amidonaphtol imprägnirte Faser in dieses Bad gebracht, so färbt sie sich nach kurzer Zeit tiefschwarz. Die Färbung ist vollständig waschecht und säurebeständig.Will the fiber impregnated with amidonaphtol brought into this bath, it turns deep black after a short time. The coloring is complete washable and acid-resistant.
Wenn an Stelle des £■- Amidonaphtols das Ct1 ß3-Amidonaphtol verwendet wird, so entsteht eine braunschwarze Färbung. If the Ct 1 ß 3 -amidonaphtol is used in place of the £ ■ - amidonaphtol, a brownish-black color is produced.
Das Verfahren läfst sich auch zum Drucken von Baumwollstoffen verwenden. In diesem Falle wird die Diazolösung unter Zusatz eines Verdickungsmittels aufgedruckt.The process can also be used to print cotton fabrics. In this In the case, the diazo solution is printed on with the addition of a thickener.
