Glad to know the Dawn worked!
Regarding dyes bleeding these days, some of that is due to regulations regarding the chemicals that can be used. Some of the older chemicals were very harmful to workers' health and to the environment and have been banned in the U.S. However, some of the chemicals no longer used in fabric dyes were also responsible for early deterioration of fabric. So, there are advantages and disadvantages to the chemicals used in today's fabrics. I, for one, am willing to trade some additional bleeding for a better environment and better health for workers. Plus, the extra bleeding is manageable simply by using Synthrapol or Dawn and sufficient water to dilute the dye bleeds.
