Batiks....colors running

Prewashing with Retayne is a great idea, but it's more complicated than just soaking a bunch of fabric. It takes very hot water and 20 minutes of agitation, either by hand or machine, for it to work properly. Here's the instructions.

How to make sure fabrics are colorfast:
I just came across a very good article written by a woman who dyes a lot of her own fabrics. She did some research and found the best way to prevent the dyes in ANY fabric from running is to let them sit in a lot of water for at least 12 hours. You can read her article here:

It depends a lot on the batiks. I don't normally prewash batiks, but I do test suspicious colors. First I rub a small piece against some white cloth to see if any color "crocks". Then I let a piece sit in a glass of water will to see if dye particles bleed into the water. Finally, I rub the damp batik against white fabric to see if any color transfers.
Most batiks I do not bother to test, and most of those I test do not bleed. A bleeder gets a Retayne treatment. (A few batiks require two Retayne treatments. If the dye isn't stable after 2 Retayne treatments, it doesn't go into a quilt.)
Another precaution I take is with the first washing of a quilt. I use Synthrapol and a *lot* of hot water for the first wash, along with several color catchers, so if there is any slight bleeding the excess dye goes out with the rinse water. I also am careful not to let damp fabrics sit next to each other; right after the washing machine, the quilt goes into the dryer.
Maybe it's the brands of batiks I buy, but I have not found them to bleed any more than other fabrics. I know that home-dyed batiks can bleed a lot, though.
