Because it is polyester, it won't take dye well.  Natural fibers (like cotton) take dye better than synthetics.  In my experience, they turn blotchy, the dye is uneven, lighter in some places and darker in others.  Bleach won't work really well either because it damages some synthetic fibers and you cannot control the color change.
