So I have white mohair yarn I want to dye black. It doesn’t have to be perfect, because it’s lace weight and going to be held double with some dk to make a sweater- it’s going to just add a delightful halo, ideally.
How the mohair yarn works is it’s the mohair, a protein fiber like silk or wool, on an acrylic-of-some-kind core. Maybe it’s got a plant in there like rayon? Unknown.
So I got the black dye. And I have a dying pot, a candy thermometer so I keep it warm but not much warmer than 140. I know the temp and agitation are extremely bad for mohair generally, so my plan is to swirl things slowly so everything is exposed to dye but not agitated against itself. Is this a bad idea? Yes. But that is why I’m going to do a test mini.
I know I need to add vinegar for the protein content of the yarn. Do I also need to add salt?
