Most are of plant origin and extracted from roots, wood, bark, berries, lichens, leaves, flowers, nuts, and seeds. Others come from insects, shellfish, and mineral compounds. Natural dyes were the only source of color for textiles, leather, basketry, and other materials until synthetic dyes were developed in the latter half of the nineteenth century. Of the thousands of natural color substances, very few became significant commercially.
Dyestuff refers to the plant or other material from which the dye is extracted. Complete palettes are achieved by dyeing in one bath and sequential dyeing in two or more baths.
Adjective or additive dyes such as madder must use a mordant (a chemical that fixes a dye) to bond with fibers. These are the most common type and have been used for at least 2,000 years.
Dyeing with Natural Dyes

Natural dyes are most often processed in this way. The dyestuff is harvested or collected, soaked in water for several hours, and heated to a low simmer for approximately an hour or more to extract the dye. The extract is poured into another pot and water is added to achieve the desired dyebath volume. Wet, pre-mordanted textile is added to the dyebath, which is heated to a low simmer for approximately an hour. After the dyebath is cool, the textile is removed. Some dyers rinse before letting the textile dry. Other dyers prefer to dry the textile for several days before rinsing.
Historic Natural Dyes

Evidence of well-developed dye works exists in many parts of the world. Ex. Ancient Egyptians, Phoenicians, and Peruvians were known for their excellent dyeing. Italian dyers were among the best from Roman times through the sixteenth century. Dyers from India were supreme in dyeing cotton. Dyers in China specialized in dyeing silk.
Natural dyes were major trade items throughout history until the development of synthetic dyes. By the early years of the twentieth century, natural dyes had been replaced in most applications. However, most of these dyes remain important for artists, craftspeople, and niche producers.
Current Use

Natural dyes are used in small quantities by artists and craftspeople. Some commercial use of natural dyes is a response to concerns about synthetic dyes and environmental pollution. Natural dyes are a renewable resource and contribute to rural economic development. However, in most commercial applications, natural dyes do not compete with synthetic dyes that are available in more colors. Contrary to common assumptions, some natural dyes have excellent fastness to light, cleaning agents, water, and perspiration. Commercially available natural dye extracts facilitate color matching and make the dyeing process less involved.
Contact dyeing is an alternate method in which the dyestuff, a tiny volume of water or other liquid, sodium chloride or mordant, and found materials like rusty nails or copper wire are placed in and around the textile that is sealed in a plastic bag or glass jar for several days, weeks, or months. Contact dyed textiles have unusual, one-ofa-kind patterns.

Interventions


1. Making natural ingredients into powder (dry in a food dryer or bake in an oven, grind, and dye)

2. Filtering raw materials

3. Using natural pigments

4. Change to 100% natural fabric and applied the coating material in the same way as the previous intervention.

5. Applying dye and baking it instead of boiling it?

6. Making a pattern frame and putting a fabric in it and dyeing it?
