Next! For this puppet I had to try something new: dyeing fur. Well, actually, I've done that before. For
Boober,
Sidebottom, and
Sage I dyed gray fur blue to get a blue-gray. I only nudged the color over a little, which is all you can do with my usual dye. Rit dye works great on feathers and Antron fleece, but faux fur is made of acetate and turns up its nose at the stuff, as I found out while making
Shonky Fraggle.
So, I bought a few samples of disperse dye, which is made for acetate, from
Aljo Dyes. And this past weekend I finally gave em a try. They're much more hardcore than Rit Dye, as they sink into the material they dye rather than sitting on top, and they require a longer time sitting in a much hotter bath. And the dye packages have scarier warnings on 'em.
My chemistry lab. I bought a stainless steel boiler just for use with dyeing, as I can't see me using dye-stained pots for stew or steaming veggies. The thermometer is also dedicated to this task. The dye bath has to be heated to 180-200 degrees F and kept there a while, then allowed to cool over time to ensure dye exhaustion (meaning that all the dye seeps into the material).
(For comparison, with Rit dye I just run hot tap water into a big plastic bucket, put the salt and dye solution in, mix well, and dip the fabric in and out and in and out until it's the right color. It's all done in the sink.)
The result:
The triangle-shaped piece at the top is the original orange fur. The four bits on either side of it are swatches I test-dyed in the Aljo dye for different amounts of time. Those on the left started out white, those on the right were originally orange. Those proved that the fur would take the dye, but to get a good dark reddish orange I'd have to let it soak in.
So, I cut out the fur, cooked up a strong dye solution, and soaked that stuff good. I let it go twice the normal time. The result is the completed tail. At first I thought I'd overshot the color, but when I put it against his orange skin it looked just right. So, yay, A+ in Chemistry 101.
As ever, I had to try the dye out on other materials while I was at it. The three small bits on the right are Antron fleece. The first two stayed in as long as the fur swatches did, and look how they slurped that color up! I chucked the third one into the dye bath after taking the fur (the puppet fur, not the swatches) out. After most of the dye had been soaked up by the fur, the fleece still turned that color, and I'd left it in only 10 minutes or so. So, yeah, it works on Antron. The results on ostrich feathers were less impressive. I guess I'll stick with Rit dye for those.
So, now I have Gobo's pelt. As soon as it dries I'll cover up his naked, reticulated shame.
