 naphtolsulfosäure andererseits enthalten, sich vorzüglich zum Färben der gemischten Faser eignen. Die animalische Faser wird im Gegensatz zur stark angefärbten   BaumwoUfaeer   fast ungefärbt gelassen. 
 EMI1.2 
 färbt in halbwollenen und halbseidenen Geweben die vegetabilische Faser blau an, während die animalische Faser fast farblos bleibt. Ersetzt man in diesem Beispiel die zweite

   IV. Das Zwischenprodukt aus   24     kg Dlanisidin-R-Salz wird   mit einer   sodaalkalischen   Auflösung von 35 kg   Azet-1.     5.   7-aminonaphtolsulfosäure vereinigt, so dass nach 24stündigem   Rühren   der Ansatz noch deutlich alkalisch bleibt. Der Farbstoff wird wie üblich verarbeitet. Er färbt in den gemachten Geweben die Baumwolle blau an und   lässt   die animalische Faser fast rein.

  Method for the representation of semi-wool or. Half-ColorestWn.
 EMI1.1
 On the other hand, contain naphthol sulfonic acid, are excellent for dyeing the mixed fiber. In contrast to the heavily colored BaumwoUfaeer, the animal fiber is left almost undyed.
 EMI1.2
 stains the vegetable fiber blue in half-wool and half-silk fabrics, while the animal fiber remains almost colorless. If you replace the second in this example
 EMI1.3
 -2.5.7-aminonaphthol sulfonic acid entered. After the batch, which has been kept alkaline with soda, has been stirred for 24 hours, the dyes have ended. The dye is sown, pressed and dried. It stains the cotton in the mixed fiber blue.
 EMI1.4
 



   IV. The intermediate product from 24 kg Dlanisidin-R-Salt is with a soda-alkaline dissolution of 35 kg Acet-1. 5. 7-aminonaphthol sulfonic acid combined, so that after stirring for 24 hours the batch still remains clearly alkaline. The dye is processed as usual. He stains the cotton in the made fabrics blue and leaves the animal fibers almost pure.
