I know that it's very hard to dye polyester, but what are the likely
results of attempting to dye such a mix using home dyeing kits?

o The colour will be very pale (e.g. pastel blue from a navy dye).
o The rayon will probably absorb much more than the polyester.
o The imperfect mix of polyester/rayon inherent in the fabric is likely
to make the result patchy.
o Even if it initially looks relatively OK (or at least acceptable), it
will tend to wash out fairly quickly.

Thanks.

I wonder how well it will tie-dye, using home dyes. It doesn't need to
look uniform. I could even take advantage of the different ways in which
the materials take the dye, perhaps.
