====== Bio dyes ====== For bio dyes, I used animal, protein fibre (80% wool, 20% silk) and vegetable, cellulose fibre (100% cotton) bases. The mordant that I used was Tartaric Acid with hibiscus die, and acidic apple vinegar modifier, with time as a variable as well. * It is important to label each fibre. I used a waterproof plasticized labeler * Important to weight the fibres, and take an average to later measure the amount od mordant to put in ====== ====== FOR COTTON: ====== ====== - Boil the 8 fibre strips for an hour in the wash with 1 spoon of baking soda. - I separated half to put in a boiling water with 6% of the net weight (0.135g of Tartaric Acid in 500mL of water) - Due to transport, I added the dye after 2 days. I boiled water and then letter it simmer on the hibiscus (around 100mL in half a cup of hibiscus flowers) for 30 minutes. Then I added the fibres and let them simmer for 45 minutes and afterwards left them overnight. - After 14 hours I removed half - After 20 hours I removed the other half - I got half of those, and simmered them in 4 spoons of apple vinegar for 5 minutes, with the hibiscus liquid. ====== ====== FOR WOOL/SILK: ====== ====== - I washed the fibres gently with lukewarm water from the tap, and a little bit of detergent. - I separated half to put in a boiling water with 6% of the net weight (0.105g of Tartaric Acid in 500mL of water) - Due to transport, I added the dye after 2 days. I boiled water and then letter it simmer on the hibiscus (around 100mL in half a cup of hibiscus flowers) for 30 minutes. Then I added the fibres and let them simmer for 45 minutes and afterwards left them overnight. - After 14 hours I removed half - After 20 hours I removed the other half - I got half of those, and simmered them in 4 spoons of apple vinegar for 5 minutes, with the hibiscus liquid. -when putting in the dyes, all the fibres were in the same boiling container ====== Results for Bio Dyes ====== 14 (14 hours), 20 (20 hours), V (vinegar as modifier), M: (mordant added).
