BASEL, SWITZERLAND, ASSIGNORS TO THE FIRM SOCIETY OF CHEMICAL INDUSTRY IN BASLE, OF BASEL, SWITZERLAND .PBQDUGTION OF FAST TIN No Drawing. Original application filed November 3, 12, 1924. Divided and this application This application is divisional of application Ser. No. 66,639, filed November 3, 1925.
It is known that insoluble dyestuffs, such as for instance certain unsulfonated azodyeanthraquinone derivatives, etc., may be employed for the production of tints on acetyl cellulose. For this purpose, however, the products in question have to be brought into a fine state of subdivision.
0 This may be done, either by boiling the dyestufl paste with soap solutions in presence of sodium carbonate and of an insoluble organic solvent, as for exampletetraline of the formula H H H Mill -IN are obtained by mixing amino-anthraquin ones having aifim'ty for acetyl cellulose with waste sulfite liquor, are well adapted to produce tints on acetyl cellulose, yielding, especially in presence of soaps or sulfonatedsoaps, as Turkey red oil, dyebaths which dye acetyl cellulose or acetyl cellulose silkvery uniform tints fast to rubbing, water, washing and, in some cases, to light.
Example 500 grams of a paste from 20 parts of 1 4- diaminoanthraquinone and 80 parts of waste sulfite liquor of 50 per cent strength are mixed intimately with 10 liters of water of 50 C. and as many liters of concentrated soap solu- TS 0N ACETYL CELLULOSE 1925, filed tions as are necessary to obtain afterwards a dyebath containing 2 parts per thousand of soap. The mixture is then diluted with cold water to about 300 liters. 10 kilograms of acetyl cellulose silk yarn are introduced into the dyebath thus obtained, worked, the dyebath brought to 75 C. within of an hour, and the goods dyed further for 15 minutes at this temperature. The yarn is then rinsed and brightened as usual. There are thus obtained bright pure violet tints. Red to orange tints are obtained with 1 5- or 1: 8-diaminoanthraquinone, 1 4-hydroxyaminoanthraquinone, 1-methoxy-4-aminoanthraquinone, etc.; blue shades with 1-aminoaryl-4- aminoanthraquinone derivatives or anthraquinone derivatives which contain more than two u-flllllllO groups.'
The process described in the example above is adapted to fabrics from cotton-acetyl cellulose sllk or viscose-acetyl cellulose silk; for union fabrics, however, containing besides acetyl cellulose animal fibers, such as wool or natural silk, it is preferable not to add any soap while preparing the dyebath. In this case it may be dyed in an acid bath, if the constitution of the dyestuffs agrees with it, without impairing the colloidal state and the 03%2VLfilty of dyeing.
at we claim is z-- The herein described process for the production of tints on acetyl cellulose, which comprises treating the acetyl cellulose with a colloidal preparation from an intermixture of aminoanthraquinones having an afiinity for acetyl cellulose with waste sulfite liquor.
In witness whereof, we have hereunto signed our names this 16th day of A ril, 1930.
