These would be fabrics in which the dye was never properly set in the factory.
The soak-in-hot-water technique will work to remove excess dye from fabrics if the dye was set properly in the factory. Many manufacturers over-saturate the fibers to the point where they cannot absorb more dye, and then do not rinse out all the excess dye. Soaking will get rid of excess dye, but will not set dyes that were never correctly set in the factory. If the remaining dye is not set dye, then the fabric will continue to bleed. Maybe forever......
