Scissor Queen is correct. You do *not* want to use Retayne at this point, as it will permanently set any bleeds. You want to use Synthrapol with lots of hot water. Domestic front loading washing machines do not have any water for this process to work. It may take several washings with Synthrapol to remove all the bleeds.
Retayne permanently sets dye. Synthrapol suspends unset dye particles in water so they can be rinsed away instead of settling into fabric.
I never rely only on color catchers for a first wash. Washing in Synthrapol with lots of water would likely have prevented this problem in the first place.
