natural dye

Natural dyeing is a technique that has been used for thousands of years but nowadays is used very little on a commercial scale. Most of the made clothes are dyed synthetically. They require vast amounts of water and many chemicals in production, which often end up in nature. Being one of the many ways fast fashion negatively impacts the environment. Natural dye is a step towards more sustainable clothing production to counteract these wasteful practices.​ I made a collection of natural dye experiments. All the pigments used are produced by hand, using fruits, veggies, and nuts that one can find from the grocery store or grow oneself. The fabrics used in these experiments are from a drift shop in Winterthur, Switzerland. The textiles used are all made out of natural fibers.​ My project includes a carbon footprint calculator. That I created to help people easily keep track of the carbon footprint caused by coloring their garments.

MY CARBON FOOTPRINT (CO2e) CALCULATOR:

About CO2e and how it differs from Co2: CO2e (also written as carbon dioxide equivalent, CO2 equivalent, or CO2eq) is a metric measure for comparing emissions of various greenhouse gases by converting amounts of other gases to the equivalent amount of CO2. If we calculate emissions based on CO2 only, we’re then ignoring the impact of other gases and, as a result, have an inaccurate picture overall. CO2e combines everything in one and attempts to convert the warming impact of the range of different gases into one single metric.Source: Cooler Future blog written by Olga Rabo. Nov 18, 2020.

This is why it is very important to look upon the bigger picture where the CO2e measurement system is created for when producing something new.  
I created this easy-to-use calculator for people who are interested in natural dyeing. It gives an idea of the amount of CO2e that natural dyeing produces with the ingredients I used in my project. This calculator can be easily modified by just adding for example new ingredients and colors to the code. I hope that this calculator helps people with their natural dye projects. The calculator gives the number of ingredients needed for the desired color and calculates the estimated carbon footprint of the coloring.

Pigments

Here you can find more information on pigments created with natural ingredients. I have showcased the ones that that I found to work best on fabrics from the ingredients that I tested out during this project.

Turmeric

Turmeric works as a natural dye with a solid pigment that keeps the color even when the fabric is dried.​

Ingredients used for pigment:

-vinegar
-fresh turmeric
-shopped boiled water
-salt 

Method: 

Start the process by soaking the fabric in boiled water mixed with vinegar. Chop the turmeric into pieces and place it into a blender accompanied by boiled water. Get rid of extra pieces by filtering them out. Add one teaspoon of salt. Mix well.

Spinach

Spinach works as a natural dye and appears as a light pigment. If the desired pigment is darker green you can try to use more spinach and soak the fabric longer in the pigment.

​Ingredients used for pigment:

-vinegar
-fresh spinach
-boiled water
-salt​

Method: 

Start the process by soaking the fabric in boiled water mixed with 1 cup of vinegar. Place the spinach into a blender accompanied with boiled water. Get rid of extra pieces by filtering them out. Add one teaspoon of salt. Mix well.

Nutmeg

Nutmeg works as a natural dye and appears as a light khaki pigment. It was hard to make the nutmeg color stable. 

​Ingredients used for pigment:

-vinegar
-fresh nutmeg
-boiled water
-salt​

Method: 

Start the process by soaking the fabric in boiled water mixed with vinegar. Place the nutmeg into a blender accompanied with boiled water. Get rid of extra pieces by filtering them out. Add salt. Mix well.

Red Cabbage

Reg Cabbage works as a natural dye and appears as a purple color. You can add baking soda to the ready-made pigment and see how the color changes to cyan. 

​Ingredients used for pigment:

-vinegar
-fresh Red Cabbage
-boiled water
-salt
-baking soda optional

​Method: 

Start the process by soaking the fabric in boiled water mixed with vinegar. Place the chopped red cabbage into a blender accompanied with boiled water. Get rid of extra pieces by filtering them out. Add salt. Mix well. If you want the color to be more blue add some baking soda into the ready-made pigment.
