It's a good idea to test the fabric after using Retayne. Drop a small swatch into water and let it sit for several hours; there should be no transfer of dye into the water. After that, rub the damp swatch against a light fabric you might use in the quilt to see if any dye transfers from rubbing. It's rare, but there is an occasional fabric whose dye may not be completely set by Retayne. At that point you can either Retayne it again and test again, or just use the fabric for something else.
Retayne would not affect the way the fabric is washed later. If dye is unset, the dye might bleed more in hot water than in cold water. However, if Retayne has succeeded in setting the dye permanently, it should not bleed under any conditions (just like fabric that comes from the store and does not bleed).
IMO, it's still a good idea to use Synthrapol the first time a quilt is washed. Synthrapol does not set dye; it suspends unset dye particles in water so they do not settle into other fabrics. Some people use both Synthrapol and several color catchers.
