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.
