I have ordered a Brother Drum Carder for myself for Christmas. (mom is getting a set of stacking boxes with clear doors for her yarn stash, shhhh don’t tell her). The Drum carder I have ordered will have 90 tpi, suitable for carding finer wools without damaging them yet coarse enough that I can card almost anything else I desire. In an effort to get into the carding spirit I also ordered a pound of undyed wool. I have played with Kool-Aid Dye in the past, causing the co-president of my guild to think I only like primary pinks and blues, but I have been hearing a lot about dying wool with Wilton and Rit Dyes. Due to this desire to experiment, I am doing some research about other peoples experiments with this dye.
The first mentioned Rit dye and a few ‘glugs’ of vinegar. Her experiment went well!
Love Knitting has an article about Wilton Food Dyes; Start by soaking the fiber in a vinegar bath, 1/4 cup to about 4 oz of fiber, for at least 20 minutes. Pour the fiber, vinegar, another 1/4 cup of vinegar into a pot. Add the color a tiny bit at a time and agitate to disperse the dye. Start on low and heat up your pot of fiber, when it is at a simmer just before boiling take it off of the stove and let it cool down. Rinse with lukewarm water until the water runs clear, then hang up to dry. There are also some tips about painting yarn, I particularly find it interesting that sponges (along with a vinegar dye mix) can be used to paint the yarn/fiber to create gradients and variations. Heat is still needed to set the fiber, so the author steamed the yarn for about 40 minutes in a steamer basket. Though they mentioned that it is possible to microwave for 1-2 minute bursts for about 5 minutes to set the yarn.
Both the RIT Dye site and Wilton Food Site have information on how to use their dyes for coloring different materials. I cannot wait to begin experimentation!
