4 DYESTUFFS.
Specificationof Letters Patent.
Application filed December 11, 1911. Serial No. 664,923.
Patented June 11, 1912.
To all whom it may concern:
Be it known that I, ADOLF Kmg'rnsz, a
subject of the Kingdom of Hungary, and
a resident of Bismarckstrasse .5, Mainkur,
Germany, have invented certainnew" and useful Improvements 1n Processes oI Dyeing Vegetable. Fibers with Halogenated f Indi 0 and Indigoid Dyestuffs, of which presence of sodium sulfid, whereas with the ollowing is afull description.
It is known that the vat dyestufls de rived from thioindigo not only dye in the presence of hydrosulfite, but also in--. the
other indigo derivatives this is not the, case so far as'regards sodium sulfid. q
I have now discovered that, in contradistinction' to indigo, halogenated indigodyestuffs such as di-, trior tetrabromo indigo, tetrachloro indigo,' or indigoid dyestufls having a halogenated indigo nucle s, dye
cotton, linen, etc, exceedingly we I with sodium sulfid, the dyeing being carried out in a manner similar to that with sulfid. colors, except that'caustic soda lye'is added to the bath.
I The employment of sodium sulfidhas the great advantage of being much cheaper than hydrosulfite and .of allowing the dyeing to be carriedout at a higher temperature. The dyestufl is also completely reduced.
'77. Tw., 20% Glauber salt.
in addition sodium agent.
Some hydrosulfite may be added. if desired toward the end of the operation,
Example: The dye bath is charged with 20% indigo MLB/ tB (tetrabromo indigo), 12% sodium sulfid, 10% caustic soda lye Havmgnow particularly described and ascertained the nature of my said invention,
and in what manner the same is to be'performed, I declare that What I claim is 1. The process of dyeing vegetable fibers.
with halogenated indigo and indigoid dyestufi's by treating the material 1n a hot,
alkaline liquorcontaining the dyestuif and 2. Thedprocess of dyeingvegetable fibers with halogenated indigo'and indigoiddyestufls by treating the material in a hot alkaline liquor containin the dyestufi' and in addition sodium sul d as a reducing agent, hydrosulfite being added only toward the end of the operation, I
In witness whereof I have hereunto signed my name this 25th day of November, 1911', in the presence of two subscribing witnesses.
