I went through a period, about a year and half ago, when I was really excited about the possibilities of this new fiber soy silk. I thought, since it wasn't widely available in a lot of colorways, and certainly not as handpainted or space dyed (except for a one or two websites here and there), that I could do some dye experiments, see what happened, and perhaps start selling handpainted soy silk in the same way that I sell handpainted tencel and other cellulose fibers.
However.
Soy silk is a protein fiber. And needs acid dyes. Or at least fiber reactive dyes set with heat and acid instead of alkaline fixer. I bought a few acid dyes. I tried Gaywool, because it was available at my local fiber shop and you need to support your local fiber shops! It is very expensive, and I only bought three colors.
Also, at that time I was going through a crockpot dyeing phase. A lot of crockpot dyeing. Trying to get a system going, because I like systems, and you need systems for repeatable results. So I was dyeing 16/2 soy silk in 1 oz. batches in the crockpot. I tried solid colors, and I tried rainbow dyeing. The colors were ok, but nothing great. Solid colors never would level completely. Then I discovered that this is called "Kettle Dyeing". Yeah, that's it....
Anyway, the strongest colors in my experiments came when I used my old faithful fiber reactive dyes. I soaked a tiny skein in full strength white vinegar for (maybe) a half hour. Then I took it out, painted it with my fiber reactive dyes, wrapped it in plastic, and put it in the microwave to heat set. I was pretty tentative with the timing. I didn't want to burn it. And this experiment was the best of all!
Now I've got umpteen balls of kettle dyed, rainbow dyed, and microwave dyed 16/2 soy silk, a 12 harness table loom that is sadly under-used, and a blog. The perfect storm.
Photos to come.
