1. Choose the correct dye for your fabric. Use, of course, 30 number Viktoria Fabric Dyes for a jet black fabric.
2. Choose the boiling method. Our dyes love hot water. It relieves the fabric and fabric absorbs the dye. This dyeing method allows you to maintain a very hot water dye liquor during your painting process, therefore you reach the darkest color possible.
3. Double the standard dye amount. More dye creates a darker color.
4. Prewashing article. This helps to remove all surfaces which may prevent dye absorption.
5. Add salt and vinegar (cotton, linen, silk, wool, nylon, rayon and ramie dyeing). To boost the color: (1) add a glass of salt while dyeing fabrics containing cotton, rayon, ramie and linen; (2) add a glass of vinegar while dyeing fabrics containing nylon, silk or wool.
6. Allow the item to stay in the dye liquor for 30 to 60 minutes by continuously stirring. The product seems darker when wet and its color lightens as long as drying.
7. And lastly use Fiske Fabric Dye Stabilizer. This is a secret formula. After dyeing (yet before washing), steeping the dyed item in a flicked water boosts the color of the product and reduce the bleeding.
