IV. BIOCHROMES¶
About Biochromes¶
This week we are exploring Biochromes which are substances produced by living organisms that have a color resulting from selective color absorption. Biological pigments or biochromes include plant pigments, flower pigments and animal pigments. We´ll be experimenting with plants, flowers, fruits and vegetables as well as a bacteria strain called Janthinobacterium Lividum.
Let´s continue by establishing the two categories of fibers we´ll be working with and how to prep them for mordanting/dyeing. First of all, as you see in the chart below, there’s Natural fibres and Manmade ones. We will only be working with natural fibres because natural dyes or inks are best absorbed by natural ones. This also applies for the bacteria.
SCOURING RATIO - Cleaning the fibres¶
Animal Fibres: 250 gr WOF (weight of dry fibre) 3L of water + 1 tsp Soda Ash + 1 tsp neutral ph baby soap. Vegetable Fibres: 450 gr WOF (weight of dry fibre) 5L of water + 2 tsps Soda Ash.
MORDANTING RATIO - Prepping the fibres for pigment absorption¶
Animal Fibres: 100 gr WOF (weight of dry fibre) 10-20%Alum of WOF + 8%Tartaric Acid of WOF. Vegetable Fibres: 100 gr WOF (weight of dry fibre) 10-15%Alum of WOF.
NOTE: These are the measurements for the amount of fabric I used, you must calculate de percentages based on the weight of your fabric (dry).

about your images..delete the tip!!
-
Remember to credit/reference all your images to their authors. Open source helps us create change faster together, but we all deserve recognition for what we make, design, think, develop.
-
remember to resize and optimize all your images. You will run out of space and the more data, the more servers, the more cooling systems and energy wasted :) make a choice at every image :)
This image is optimised in size with resolution 72 and passed through tinypng for final optimisation. Remove tips when you don't need them anymore!
get inspired!

Documenting experiments¶
example from the documentation of Petra Garaiová FabTextiles Barcelona 2021-22
TEST 01 - SILK¶
Material name | Fabric composition | Breathability | Moisture-wicking abilities | Heat retention abilities | Stretchability | Washing temperatures |
---|---|---|---|---|---|---|
Silk | Animal fibers - silkworm insect | Highly breathable | High | Low | Low | Cool or warm |
RESULTS¶
Two ways of showcasing and comparing results with images below
On the left an image of a sample made by xxx with xxx. The dye is more xxx. On the right, an image of a sample made by xxx with xxx and xxx. Here the dye is more xxx.
