Default Dyeing a polyester/rayon mix

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?

Thanks,

Partner (who knows about these things) used the word 'disastrous'.

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.

Partner would not attempt it - just a waste of money on the dye.

If you are nonetheless desperate to try, a dye from a specialist
supplier (rather than the usual high street Dylon) might be a better choice.

E.g. (a good supplier but without knowing anything about the specific
dyes listed on this page):

But let us know what results you achieve if you do go ahead.

about zero. You might look at vinyl dyes, those can dye plastics - how
they perform on your plastics I dont know, just something to look
into.

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.

That works.

The polyester-rayon issue is a bit irrelevant, because the granularity
is very small.

I've dine a BIT of this with nylon and dylon years ago, and, provided
you leave the fabric in there and keep stirring for a long time, results
are not bad.


use a lot of dye and not too much water.
