First, to adress some of the comments:
When I first used the Retayne, I put the fabric in a large stock pot and measured the temperature of the water with a thermometer. It was way in excess of the required temp, up around 180 degrees. I soaked it for even longer than the required time.
I got Synthrapol and have now washed the fabric at least five more times. (I've lost count.) The water was still a bright blue the last time. Is this reasonable? Is there anyone out there that has used Hoffman's Marlin batik and washed it? I would be interested to see what your experience has been.
I've used all of the Synthrapol and I don't want to waste any more if the fact it is still bleeding significantly after so many washings indicates the fabric is defective. However, if this is reasonable, I'll go get more and keep going.
Thanks.
