4. Biofabricating Dyes and Materials#




Assignment of the week#

This week could be divided in three big topic:

Natural dyes#

The first topic we explored is Natural dyes. Here in the TextileLab Amsterdam there’s so many examples from the archive from witch we could get inspiration. We started working on the natural dyes on Wednesday morring. This is how we procced:

The process for Natural dyes#

Weigh dry material#

The first thing to do is to weigh, when they’re still dry, the material we’re going to use.

Wash and scour the fibers#

We must distinguish the preparation for plant and animal fibers:


A mordant is a substance used to set and dyes on fabrics.

We have used three different mordants: alum, copper and iron. For some dye bath the mordant change the final color on the fibers.

More about mordant


In this photos you can se how the different mordant change the color of the fabric and the yarns as soons as they are soak in the solution.

Dye bath#

For this week join us also three other girls: Julia, Lara and Scarlett. Each of us dyed with a different ingredient. I choose the Hibiscus.




Natural dyes’ archive#

I’ve started my archive. The differtent samples of the same dye are divided into iron, copper and alum.

I’m totally in love with dyed velvet.

Cecilia’s recepies and instructions.#

Here you can find the recepies we’ve followed.

In future I would like to work more on natural dyeing with; I would like to dry to dyeing whit:

Bacteria dyeing#

Janthinobacterium lividum#

These mutualistic bacteria can be found on the skin of the salamander and produce the antifungal compound violacein. The fungal pathogen’s growth will be hindered or it might even be killed by this compound. This way, the purple Janthinobacterium aids the salamander’s immune system.

The dark purple appearance of Janthinobacterium lividum is caused by the substance violacein, produced by the bacterium itself. This pigment is an antioxidant, and also has anti-fungal and anti-bacterial effects.

Inoculate the petri dish#

Cecilia shows us how how to proceed for the dyeing through bacteria. Here the instructions:

Kill the bacteria!#

Monday 22-10-18

We killed the bacteria, this also mean sterilize the fabric. We used the pressure cooker and than we’ve washed our textile with water and soap.


The result has been this..
