STATES PATENT OFFI E.
ARTHUR WEINBERG, OF FRANKFORT-ON-THE-MAIN, GERMANY, ASSIGNOR TO LEOPOLD OASSELLA & 00., OF SAME PLACE.
PROCESS OF DYEING BY THE AID OF PARAMI DODIPHENYLAMIN.
SPECIFICATION forming part of Letters Patent No. 517,533, dated April 3, 1894.
Application filed November 29,1893i Serial No. 492/1 04. (No specimens.) Patented in England March 2,1893, No. 4,612, and in France March 4,1898,No.228,395.
T at whom it may concern.-
Be it known that I, ARTHUR WEINBERG, a subject of the King of Prussia, Emperor of Germany, and a resident of Fraukfort-on-the- Main, Germany, have invented new and useful Improvements in the Production on the Fiber, by the Aid of Paramidodiphenylamin, of Dye-Stuffs Fast to Light and Washing, (for which patents have beenobtained in Great IO Britain, No. 4,612, dated March 2, 1893, and
in France, No. 228,395, dated March 4, 1893,)
of which the following is a specification.
The object of this invention is a new method of the production on the fiber, by the aid of 1 5 para-amidodiphenylamin, of dye-stuffs fast to light and washing. The para-amidodiphenylamin cannot be combined withdiazo bodies to form normal azo-dye-stuffs. If the two bodies are brought together no diazoamido compounds result, but nitrogen is generated, and colorless or weakly colored substances are formed, the constitution of which has not yet been ascertained. In quite a difierent and unforeseen manner the para-amidodiphenylamin reacts on diazo compounds produced on the fiber from dyestufis which contain diazotizableamido-groups. In these cases intense and exceedingly fast dyeings are produced. For this purpose the most useful 0 among the diazotizable dye-stuffs on the one hand, are the diazo dye-stuffs in general deriving from paradiamins, such as benzidin and its analogous bodies, and on the other hand, amidonaphtholsulfo acids, alphanaph- 3 5 thylarnin, alpha naphthylaminsulfo acids alpha beta or alpha betaalpha beta amidonaphtholether, alpha beta amidonaphtholethersulfo acid. Of such dye-stuffs are of special value the products from gamma amidonaphtholsulfo acid, namely diamin black R and B, diamin blue black E, diamin black B H, diamin brown V, the products from amidonaphtholdisulfonic acid H, as diamin blue BX, 213,313, the naphthylene violet described in theUnited States Letters PatentNo.4.64,566, the brown dye stuffs mentioned in the German Patent No. 58,617 as well as other substitutes recommended for the same purposes, which are brought into the market under different denominations as diazurin, diazoblack, 5o diazobrown, benzoblue, Nyanza black, Tabora black, Zambezi blue, &c.
The process is explained by the following example: One hundred kilos cotton are dyed in an alkaline bath with five kilos diamin blue 5 black E, for-one hour at the boil. It is rinsed and then entered into a cold bath, in which are dissolved 0.5 kilos nitrite and which is acidulated with two kilos muriatic acid. After about five minutes the diazotation is terminated. Then the cotton is entered after being rinsed into a third bath, containing a solution of 1.5 kilos chlorh yd rate of para-amidodiphenylamin. At once a dark blue dyeing appears, which is fast to light and washing. In an analogous way the other colors are developed.
Having now particularly'described and ascertained the nature of my said invention and in what manner the same is to be performed, what I claim, and desire to secure by Letters Patent, is
The method of producing fast colors on the fiber dyed with a diazotizable dye-stuff by treating such dyeings in a first bath with free nitrous acid and developing the color in a second bath containing para-amidodiphenyl amin substantially as herein described.
In testimony that Iclaim the foregoing as my invention I have signed my name,in pres- 8o ence of two witnesses, this 11th day of November, 1893.
ARTHUR WEINBERG.
