DYEING or WOOL AND /OR SILK.
N Drawing. Application filed November 7, 1927, Serial No. 231,776, and in Great Britain November 26,
Theinvention relates to the dyeing of wool and/or silk, in the course of experiments in which we have found that certain Watersoluble hydroxy-halogen benzoquinones have a strong affinity for such fibres, both when mordanted and unmordanted, and are capable of being fixed to give very fast shades.
The invention consists in the employment, as dyestuffs for W001 and/or silk, of 1-4 di hydroxy 2-5 dichlor benzoquinone or 1-4 di hydroXy 2-5 dibrom benzoquinone, such dyestuffs being applied from an ordinary acid dyebath and fixed by afterchromingor by immersion in a boiling solution of a suitable metallic salt. The structural formulas for the hydroxy-halogen benzoquinones specified are as follows:
01 OH 1-4 di hydroxy 2- 5 di chlor Ho 01 benzo quinone 0 ll Br 1-4 di hydroxy 2-5 di brom HO- Br benzo quinone As an example, 1 -4 di hydroxy 2-5 dichlor qumone dyes wool from an ordinary acid dyebath giving red brown shades which, if
afterchromed in the usual Way, are very fast.
- ters Patent is 1. In the dyeing of Wool and/or silk, the employment as dyestuffs of water-soluble 1 -4 di hydroxy 2 5 di halogen-benzoquinones applied from an acid dye bath.
2. The dyeing of wool and/or silk by means of 1-4 di hydroxy 2-5 dichlor bezo quinone applied from an acid dye bath.
In testimony whereof I aflix my signature.
