To Dye Cotton Dark Brown
Prepare a
mordant bath of 10 pounds of catechu, 2 pounds of logwood extract, and ¼
pound magenta (roseine), and bring to a boil; work the goods therein for 3
hours at that temperature; then put into a fresh dye bath made up of 3
pounds of bichromate of potash and 2 pounds of sal soda, and dye to shade.
These proportions are for a dye bath to dye 100 pounds of cotton goods at a
time. |
