4. Biofabricating Dyes and Materials#
This week I worked on natural dyes and bioplastics :D
For the natural dyes i used Achiote, Bugambilia flowers and Chile Mulato.
Procedure: For Achiote: Boil some distilled water and then pour it into a glass and then put some achiote seed on the hot water, mix it and let it for 2 days
For bugambilia: Boil some distilled water and then put 30%of hot water and 70% of ethanol on a glass, then add the flowers and mix, let for 2 days. For Chile: Boil some distilled water and then put 30%of hot water and 70% of ethanol on a glass, then add the Dried chillies and mix, let for 2 days. For this assigmnet i used coarse cloth
In order to obtain different coloures i used 3 different treatments for each dye source: Vinegar, baking soda and the control, as pH can change the scale of colours Vinegar and baking soda were used to change the pH of the solution Achiote Bugambilia flower Chillli
I meassured the pH , to see haw the pH change the tone
Results After i let the cloth for 3 days soaking on the solutions:
Other dyes: Jamaica:
Turmeric
Second Phase experimentation#
I tried different solvents such as water, ethanol and acetone , and natural pigments such as curcuma, hibiscus, algae, chilli and paprika Every source was soaked with one solvent and then i set a piece of fabric on the mixture.
i let the piece of fabric soaking for 24 hours, after that i let them dry:
BIOPLASTICS#
SCOBY/Kombucha I tried black tea with honey and boiled oranges skins with sugar as substrate for SCOBY
Obtaining after 9 days: Here i did the comparison with water and with sugar
Coconut fiber I did a bioplastic using cornstarch (Maizena), glycerin and coconut fiber
Procedure i added 3 grams of each ingredient and adding 15 ml of distilled water, then i mixed them heated them a bit
Finally
Fruit leather#
I have tried fruit leather using oranges skins and heat at different temperatures in order to get different color tones
Cristalization#
i tried with sugar and salt crystals
With sugar
