, PROCESS OF DYEING AND PRODUCT THEREOF.
No Drawing.
To all whom it may concern:
Be it: known that I, Josnrn Dl-ZINE'L, citizen of the German Empire, residing at Elberfeld, Germany, have invented new and useful l mprovements in Processes of Dyeing and Products Thereof, of which the tel- 'sulfite solution 20 Be. and 6 liters caustic lowing is a specification.
I have made the surprising discovery that the dibenzoyl1.5-diaminoanthraquinone can be used as a valuable Vtlt dye. It yields with alkalinereducing agents .a vat which dyes the textile .tiber a yellow shade of excellent fastness.
In order to illustrate my new process more fully the following example is given, the parts being by weight: Stir up 20 kilos. of dibenzoyl-l.ii-diaminoanthraquinone (10 per cent. paste) -with liters of warm water, add. to this mixture 40 liters of a hydrosoda lye 30 136. After a short time the color is completely dissolved.
. Prepare a dye bath which should contain 2000 liters *ateir, one-half liter caustic soda lye 30 1%. and 2' liters hydrosul tite solution and 80 parts of common salt and add to this cold bath the dye solution prepared as above indicated, through a sieve. Stir the loath well, let stand during some minutes, enter 100 kilos well wetted out cotton and work for 1 hour in the cold bath. After dyeing, squeeze out well, rinse, and acidulate the goods in a hath containing 2 ccm. sult'urie acid of 66 136. per liter, rinse and finally soap. A very fast clear yellow shade is thus obtained. a
lVool is dyed in an analogous way: Stir up 10 kilos dibenzoyl-l.fi-diaminoanthraqninone (10 per cent.) with 9-10 kilos causti soda lye 30" PM. and 30 liters of a hydrosultite solution 17 Be. lVhcn all the color is thormighly dissolved, add this solution to the dye bath which consists of 1200-1500 liters of water of 30 1., to which liter caustic soda lye 30 He. and 2 liters of a hydrosulfite solution 17 and 20-40 kilos Glaubers salt has previously been added. llnter 50 kilos wool, work for K; to 1 hour Specification of Letters Patent.
Application filed April 29, 1909. Serial No. 492,989.
.mersed in the liquor.
at 13p (3., the goods being continually in1 v I Patented Oct. 4, 1910.
After dyeing, squeeze out well, oxidize by exposure" to air, rinse, acidulate, wash and dry. very fast yellow shade is thus obtained.
\ Silk and charged silk is dyed in an analogous way.
I claim 1. The process of dyeing textile fiber which consists in reacting on dibcnzoyl-LS- diaminoanthraquinone with suitable reducing agents to form leuco compounds which are then applied to the fiber and finally oxidized, thus producing on the fiber a yellow shade of extreme fastness.
2. The process of dyeing textile fiber which consists in reacting on dibenzoyl ljdiaminoanthraquinone with alkaline reduc ing agents to form leuco compounds which are then applied to the fiber-and finally oxidized, thus producing on the fiber a yellow shade of extreme fastness.
3. The process of dyeing textile fiber which consists inreacting on dibenz0yl-1.5- diaminoanthraquinone with hydrosulfite and caustic soda lye to form leuco compounds which are then applied to the fiber and finally oxidized, thus producing on the fiber a yellow shade of extreme fastness.
4.. As a new article of manufacture, yellow colored textile fiber impregnated with the oxidation products of the leuco compound oft dihenzoyl-1.5diaminoanthraquinone whic treated fiber remains unchanged upon boiling with 10% inuriatic acid, and also re mains unchanged when touched with cold concentrated sulfuric acid and dilute caustic potash; and which upon being touched with a watery solution coi'itaining 0.4 of anhydrous lrydrosulfite ofsodium and ().S'/ of caustic soda changes its color of yellow to olive brown which on exposure to air assumes again its original appearance.
In testimony whereof I have hereunto set my hand in the presence oftwo subscribing witnesses.
