UNITED STATES- PATENT OFFICE.
OSCAR JAEOK, OF ELBERFELD, GERMANY, ASSIGNOR TO FARBENFABRIKEN OF ELBERFELD 00., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
PROCESS OF DYEING.
SPECIFICATION forming part of Letters Patent No. 717,749, dated January 6, 1903. Application filed October 2, 1902. Serial No. 125,696. (No specimens.)
To aZZ whom it may concern:
Be it known that I, OSCAR J AEGK, doctor of philosophy, chemist, (assignor to the FARBEN- FABRIKEN or ELBERFELD 00., of New York,) residing at Elberfeld, Germany, have invented a new and useful Improvement in Processes of Dyeing; and I hereby declare the following to be a clear and exact description of my invention.
As is known, cotton goods dyed with sulfurized substantive coloring-matters are often subjected to an after-treatment for the pur pose of rendering the shades faster or brighter. The steaming operation and the treatment with hydrogen peroxid, with chromates, with sulfate of copper, with zinc salts, or the like are well-known operations. Another process of after-treatment was described in the United States Letters Patent No. 688,999, dated December 17, 1901. treating cotton dyed with sulfurized dyestuffs with alkylating agents.
I have now found a new and valuable process of after-treatment, consisting in treating the goods dyed with sulfurized dyestufis with neutral sulfites, after which treatment it is suitable to expose them to the influence of the air. The results are remarkable, especially when usingthosedyestuffs which by theknown process of after-treatment give a still more valuable shadesuch, for instance, as immedial blue 0 R, katigen-indigov B extra and R extra, immedial black V extra, katigen blueblack R, or'the like. The action of the sulfites takes place with great facility. It is genorally completed in a short time on working at a temperature of from to 80 centigrade. The resulting shades are mostly distinguished for great brightness and fastness. They have generally a certain resemblance to the shades obtained bysteaming the dyed cotton in the presence of alkalies. The low price of the sulfites and the simple management are of great technical value for the new process of after-treatment.
In carrying out my process practicallyI can This process consists in proceed as follows: The cotton, dyed with ten per cent. of immedial blue O R, rinsed, and exposed to the air for a short while, is placed in a bath containing two grams per liter of neutral sodium sulfite. It is handled in the dye-bath for half an hour, (the temperature thereof being kept at about 80 centigrade,) rinsed, and dried. By means of this treatment the greenish-black shade of the cotton turns into a bright navy-blue.
The process of after-treatment can also be carried out in the following manner: The dyed goods are rinsed and passed two or three times through a bath containing from one to two per cent. of sodium sulfite, (Na SO The cotton is then squeezed and dried without further rinsing. By means of this operation the shade is changed in a manner similar to that above described.
It may, however, be pointed out that the temperature, the duration of after-treatment, and'the quantities of sulfites can be varied within wide limits. On using higher temperatures and larger quantities of sulfites the after-treatment iseffected in a shorter time.
The process of after-treatment is the same when other sulfurized colors are used.
