The dye is Malachite green specifically.
I understand that tannic acid has many hydrogen bonds making it very polar, but i don't understand how it is a mordant between a fibre and the dye.
Any help is much appreciated.
I just gave. Give what you can, even a dollar one time it's a single meal. Do what you can when you can, there is no obligation. It's just a one time gift.
Please help if you can, if you cant, tell others.
