Google Patents CN102604419B - Method for preparing taro stem leaf vegetable dye and dyeing natural silk or wool by using taro stem leaf vegetable dye Overall, I sort of like how the sumac dye has a variegated purplish pink hue.CN102604419B - Method for preparing taro stem leaf vegetable dye and dyeing natural silk or wool by using taro stem leaf vegetable dye I don’t think the yellow shade interfered with the end dye result but the blotches did. It left the material splotchy and tinted yellow. That is due to the second step in my mordant that included tannic acid. This photo is linen napkins dyed in sumac berries with a three step mordant. ![]() I loved some of the colors and others….not so much. Line Dry.īelow are the photos of what happened when I dyed with sumac berries. Let the material cool to room temperature and then you can rinse them out until the water runs clear. Remove the material from the pot and place in a bowl or tub. Do not leave the material in the iron mordant more than 10-15 minutes. I placed the materials directly from the dye pot into the iron mordant and brought it to a simmer for 10 minutes. This photo is before the mixture has set for a few days. ![]() After removing from the dye bath I prepared a pot of water and added a dash of iron mordant which I made from rusty nails.ġ glass jar, handful of rusty nails, 1 part white vinegar, 2 parts water. Rinse the material well until the water runs clear. You don’t want the temperature of the material to be different from the temperature of the water you are using otherwise it “shocks” the fiber and can felt or shrink it. Then I put it in a plastic tub and rinse in room temperature water. When you are ready to remove the material I found it best to lift gently with a spoon and let the dye drain off. You can leave it another day at room temperature in the pot. At this point I check to see if the material has absorbed the dye as I would like. Turn off heat and let the material stay in the dye bath overnight. I also set a metal strainer at the top of the pot to keep the material submerged in the dye. I use a wooden chopstick to push the fabric around. If the skeins or fabric are crammed in the pot the dye won’t set evenly. Be sure there is plenty of room for the material to float around. Gently squeeze the water out and place into the room temperature dye pot. Let it sit in a bowl or bucket for about 20 minutes to ensure that all the material has absorbed water. To begin the dye process wet your material in cool water. I will follow up with the mordant process for both protein and cellulose fibers in another blog. For the cotton and linen items, I up-cycle from garage sales and second hand stores. I use my own wool and alpaca yarn grown on my farm. Depending on what type of material you are using the process will be different. ![]() I usually have my items already scoured and a pre-mordant on them. I recommend preparing your wool or other material ahead of time.
