Thank you! With turmeric, I don't think mordant will help it be colorfast over the long term, but I do think using mordant will help the color last longer than it would without it. And yes, aluminum acetate can be added to the turmeric dye, but it ( as well as bi-carb) has the potential to change the color of the dye to red or something similar. Pre-mordanting might be better. Also, if you have access to fresh turmeric root to experiment with, you might find that the color lasts longer than what's achieved with powder. Thank you for watching and commenting!

Thanks for the question! Salt can be used but it does not help dye permanently bond to the fabric. It's useful for pulling the dye out of the dye bath and onto the fabric. The most common mordant is alum (aluminum potassium sulfate). It can be used to help the dye bind to the fabric and not just superficially stick to it like salt. You can also use aluminum acetate. I posted a video on how to make it: kzfaq.info/get/bejne/hNClZ9CC3pmxpoE.htmlsi=uRS7A3y0h_ezR0H8. If you're dyeing cellulose fibers like cotton or linen, an even better process is to first soak the fabric in a tannin solution before applying the mordant. I've found that this can help form an even better bond.

With natural dyes like this one, it's best to use cellulose fabrics (cotton, linen, bamboo, etc) or protein (silk, wool). With synthetic fabrics like polyester, the dye won't penetrate. Now, if you mean woven or knit, then either works. I've used both with success.

Oh, wow! That's so cool and unexpected! Thanks for letting me know. I'll be prepared to answer any questions that might come up.☺

Turmeric is one of those dyes considered to be fugitive--it eventually fades. However, the color can last a long time before it does ( especially if not exposed to direct sun or washed excessively). When I dye clothing/textiles with turmeric, I typically just redye it once it fades.
