Aniline Violet and Purple
Acidulate
the bath by sulphuric acid, or use sulphate of soda; both these substances
render the shade bluish. Dye at 212° F. to give a fair middle shade 10
pounds of wool, a quantity of solution equal to ½ to ¾ ounces of the solid
dye will be required. The color of the dyed fabric is improved by washing in
soap and water and then passing through a bath soured by sulphuric acid. |
