I recently purchased some merino/viscose roving, and it's GORGEOUS, but I just realized that I don't know anything about dyeing viscose.  All I have are acid dyes, will those work?  At worst, the dyes will just dye the wool and leave the viscose white, right?

Any info is appreciated!

The viscose is a plant fiber so it should just stay white if you use an acid dye.. I don't know for sure though. Take a little piece and dye it to see what happens!

You are going to need reactive dyes to dye the viscose.  I've never tried it, but Pro Chem claims that the Pro Mx dyes with dye wool as well as cellulose fibers.  Take a look here...

While I personally do believe that fiber reactive dyes are so much better than direct dyes and normally suggest that people use the former instead of the latter, this time I feel I should do the opposite. Fiber reactive dyes need a high ph to work on cotton and it would most likely damage the wool. If you use the mx dye to dye the wool, you'd have to lower the ph by adding vinegar and it will work just like an acid dye: it won't dye the cellulose in an acidic state.

Direct dyes dye cellulose and just need salt and heat to work and won't damage the wool but they're not very washfast. A union or all purpose dye like RIT contains both an acid dye and a direct dye. The acid dye in a union dye is usually a levelling dye though, and levelling dyes aren't very washfast either.

If you just use acid dye on the roving, the viscose part should remain white.
Some acid dyes stain cellulose while others don't, so there is a chance that the viscose may be stained then fade to white after a few washings.
Either way, neither the acid dye or the vinegar will damage the viscose.

I've dyed merino/bamboo mill end roving before, and the acid dyes dye the wool but leave the cellulose white. It's a nice effect, and I spun some really pretty yarns from it! It should be the same for any wool/cellulose fiber blend. Here is one of the batches of fiber I dyed:

If you want to try a blend that WILL dye with acid dyes, try merino/soysilk - that one just took my breath away! Here is one of the yarns I spun from it:

Oooo thanks for sharing, those are lovely! I do really like the effect of the viscose staying white amongst the rest of the dyed fibers. Very nice!
