This refers to the dyeing agents in use for what we call the Clean Clothes project; exclusively using dyes obtained directly from naturally occurring and replenishable plants, minerals, or resins.
These are dyes which can be fixed to fabric through entirely non-toxic binding processes and are biodegrade in the local ecosystem. Color gradation and intensity are the result of the number of times the garment is dipped into the dye solution. Remember to follow the care instructions for your naturally dyed clothes.
See a product's page to learn more about its dyeing process.
