Exploring Biochromes: Natural Dyes for Textiles

This week, we dove into the fascinating world of biochromes, exploring the possibilities of dyeing and painting fabrics using natural materials.

References & Inspiration

One of the most iconic references in the history of dyeing is the tie-dye movement of the 1960s, when vibrant colors and psychedelic patterns became an artistic and cultural expression. This technique defined an era but also inspires us to seek more sustainable and environmentally friendly methods today.

Tools

Pots: For boiling materials and preparing dyes.

Measuring cups: To measure precise amounts of water and other liquids.

Spoons: For stirring and mixing ingredients.

Silicone spatula: Ideal for mixing without damaging surfaces.

Scale: To weigh materials accurately.

Bowls: To hold dyes or materials before and after the process.

Containers: For storing dyes and pigments.

Tape: Useful for labeling or protecting specific areas of fabrics.

Marker: To label or identify colors and materials.

Gloves: To protect your hands from stains or heat.

Fine mesh strainer: To strain pigments and remove solid residues.

Heat source: Such as a stove, portable burner, or electric heater.

Drying rack: For drying dyed fabrics.

pH strips: To measure and adjust the pH of the dyes.

Plastic sheeting or newspaper: To protect your workspace.

Mortar and pestle: For crushing plant materials and extracting pigments.

Brushes: If you prefer painting instead of immersion dyeing.

Spray bottles: For evenly applying dyes.

Thermometer: To monitor the dye's temperature while boiling.

Clothespins or clips: To hold fabrics while drying or during dyeing.

Plastic dropper or pipette: For adding dyes or adjusting pH in small amounts.

Protective apron: To keep your clothes stain-free.

Process and workflow

There are many ways to create pigments and dye fabrics naturally. In our case, we collected various peels and vegetable scraps, such as beetroot, onion skins, and avocado peels, among others. These materials are not only easy to find but also help repurpose organic waste, contributing to an eco-friendly approach.

To extract the colors, most materials need to be boiled for at least two hours. This process allows the water to absorb the pigments intensely, achieving the strong hues required for dyeing.

It also depends on how long you leave the textile immersed in the pigment, as this determines whether the color turns out stronger or lighter.

One of the most fascinating discoveries was learning how the pH of the dye can influence the final color. Depending on the ingredients used, adjusting the pH (for example, by adding an acid or alkali) can completely transform the shade. This chemical interplay opens endless creative possibilities for customizing designs.

For example, here we can see how the same pigment, when its pH is modified, can produce 4 or 5 different shades of color. In some cases, the color even changes completelly
