Research

Biochromes, AI image

In the quest for sustainable and eco-friendly alternatives, biochromes have emerged as a revolutionary solution in the textile industry. Biochromes, natural pigments derived from biological sources such as plants, algae, and microorganisms, offer a vibrant and diverse palette of colors. Unlike synthetic dyes, which often rely on harmful chemicals and extensive water usage, biochromes present a more environmentally friendly option. Their production and application processes are typically less polluting, reducing the ecological footprint of textile manufacturing. This essay explores the significance of biochromes, highlighting their environmental benefits and their potential to transform the textile industry into a more sustainable and aesthetically pleasing domain.

Oaxaca’s natural dyed textiles are a testament to the region’s rich cultural heritage and artistic ingenuity. These textiles, created using traditional methods passed down through generations, are dyed with natural pigments extracted from local plants, insects, and minerals. The result is a stunning array of colors that are both vibrant and harmonious, reflecting the natural beauty of Oaxaca’s landscapes. The use of natural dyes not only enhances the aesthetic appeal of these textiles but also underscores a commitment to sustainable and eco-friendly practices, making them a cherished and environmentally conscious choice for artisans and consumers alike.

Natural fibers: cotton fabric, woollen cloth

Process and workflow

First

We worked together on friday. First we cut the fabrics in 10 by 10 cm squares. We decided to use cotton fiber "manta" fabric for plant based fabric and woollen cloth for animal origin fiber fabrics. The video was uploaded by Raúl.

To cut this materials with laser I used the following parameters: Max POWER: 35 Min POWER: 25 Work SPEED mm/s: 60

The first important data that we had was the Weight of Fiber (WOF). Its importance is that every calculation we made is based on this numbers.

WOF of 10 by 10 samples of cotton fabric is 1.6 gr

WOF of 10 by 10 cm samples whoolen cloth is 2.6 gr

Second Step


Fiber scouring with baking soda

The second step was the scouring of fibers with baking soda.

The materials

* 4 lt of water
* Sodium carbonate, at 2% of WOF

Recipe:

1. Weigh of fabric (WOF). Cotton, linen...
2. Heat the water in a pot.
3. Add 2% WOF of the carbonated soda to the water and stir.
4. Add the fibers (pre-cut shapes on the laser cutter).
5. It simmer for an hour.
6. Remove the fibers and wash them.

Third Step: Mordant

A mordant is a substance that helps dyes stick to fabrics or tissues. It works by forming a coordination complex with the dye, which then attaches to the fabric. Mordants can be applied before, during, or after dyeing wikipedia

Materials: - Water: 4-5 l - Alum: 15 % WOF for the cotton fabric - Aluminium Sulfate for the wool cloth

Recipe: 1. Weigh of fabric(WOF). Cotton, linen... 2. Heat the water in a pot. 3. Add 15% WOF of alum to the water and stir. 4. It simmer for an 45 minutes. 5. Remove the fibers and wash them.
