 EMI1.1 
 



   Es wurde die überraschende und technisch ausserordentlich wichtige Beobachtung   gemacht,   dass das Dibenzoyl-1,5- und 1,8-diaminoanthrachinon die Eigenschaft haben, die pflanzliche Faser nach der Küpenfärbemethode in ganz hervorragend schönen und echten goldgelben Nuancen anzufärben. 



   Beispiel. 



   Färbevorschrift für 100 kg Baumwollgarn. 
 EMI1.2 
   170 Bé. Man geht nun   mit dem Garn ein und zieht zirka eine Stunde bei gewöhnlicher Temperatur unter der Flotte um. Hierauf wird das Garn herausgenommen, abgewunden, kurze Zeit an der Luft verhängt, gewaschen, abgesäuert, wieder gewaschen   und   warm oder kochend geseift, sodann gespült und getrocknet. Man   erhält 80   sehr lebhafte,   echte,   goldgelbe NUancen. Sehr ähnliche NUancen erhält man bei Verwendung des isomeren 1 8-Derivats. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

 EMI1.1
 



   The surprising and technically extremely important observation was made that the dibenzoyl-1,5- and 1,8-diaminoanthraquinone have the property of coloring the vegetable fibers by the vat dyeing method in extremely beautiful and genuine golden-yellow shades.



   Example.



   Dyeing instructions for 100 kg cotton yarn.
 EMI1.2
   170 Bé. You now go in with the yarn and move under the liquor for about an hour at normal temperature. The yarn is then taken out, unwound, hung in the air for a short time, washed, acidified, washed again and soaped warm or at the boil, then rinsed and dried. You get 80 very lively, real, golden yellow shades. Very similar nuances are obtained when using the isomeric 18 derivative.
