MARIA S GHOLZ, OF LEICHLINGEN, GERMANY.
PROCESS FOR DYEING TEXTILE AND LIKE MATERIALS.
No Drawing. Original application filed June 25, 1923, Serial No. 647,759. Divided and this application filed January 17, 1925.
To (ZZZ whom it may concern:
. Be it known that I, MARIA ScrroLz, citizen of Germany, residing at Leichlingen, Germany, have invented certain new and useful Improvements in Processes for Dyeing Te: tile and like Material, of which the following is a specification.
This application is divisional of my copending application, Serial No. 647 ,7 59, filed June 25, 1923.
My invention has reference to an improvement in the art of dyeing textile and other mate ial, and it relates more particularly to an improvement in the step of fixing the color on the dyed material, and the object of the invention is to materially shorten and cheapen the color fixing operation and improve at the same time the color fastness of the goods.
In the prior art the dyestuffs are commonly fixed by subjecting the dyed material to the action of steam within a closed chamber or treating it by the Mather-Flatt process. These procedures are time-consuming, expensive, and do not yield an evenly dyed-- through material.
My invention broadly consists in subjecting the dyed material for a relatively very short period, generally not over one minute, to the action 01 a boiling hot saline solution, such as common salt (sodium chloride) or Glaubers salt (sodium sulfate), to which has been added about 10% of acetic acid; or similar salts, which even in strong solution will not affect the dyestull deposited on the material.
Since the dyeing of porous material is, by general acceptance, based upon the phenomenon that the dye migrates into the fibre, since the latter shows a stronger attraction to the dye than does the dye solution, the astonishing effect of my new procedure undoubtedly is due to the fact that the hot saline bath takes up more or less water from Serial No. 3,049.
the dye solution absorbed by the material, and since the fixing material itself does not react dissolvingly on the dyestufi', the latter is forced to migrate into the fibre and settle therein.
The material is passed into the hot saline bathe preferably immediately or soon after coming from the dye bath, when itis still in more or less Wet state, and is left therein normally not over one minute. The new process can also be used to advantage for improving goods previously dyed and finished by other processes, to render them still more color-fast. This is of great importance since it permits the use of cheaper grades of dyestufl's With perfect results in the finished products. 7
The goods are finally Washed and aftertreated in suitable manner. Goods treated according to my invention are color-fast to all tests to the highest degree.
lVhat I claim is:-
1. In. the art of dyeing, the described color fixing step, which consists in relatively quickly passing the dyed material through a hot aqueous saline solution.
2. In the art of dyeing, the described color fixing step, which consists in relatively quickly passing the dyed material through a hot aqueous saline solution in. the presence of a relatively small percentage of acetic acid 3. In the art of dyeing, the described color fixing step, which consists in relatively quickly passing the dyed material through a hot sodium chloride and acetic acid solution.
4. In the art of dyeing, the described color fixing step, which consists in relatively quickly passing the dyed material through a boiling hot saline solution having an admixture of around 10 percent of acetic acid.
