indigoblue

The indigo plant, known as Indigofera tinctoria, is cultivated in Oaxaca, Mexico, where it is used to extract the blue dye called añil. This traditional dyeing process involves fermenting the leaves to produce a rich, vibrant blue color, which is highly valued in textile arts. Indigo dyeing has a long history in the region, contributing to the local culture and economy through artisanal crafts. The unique techniques and deep cultural significance of indigo dyeing continue to be celebrated in Oaxaca today.

Process and workflow

mordant

  1. How to use mordants to fix dyes to fabrics:

Alum: Dissolve in hot water, soak the damp fabric in the solution, and let it sit for a while to ensure the mordant adheres. Rinse before dyeing.

Iron (Ferrous Sulfate): Prepare a solution and soak the fabric, repeating the process to achieve the desired color intensity. Rinse well afterward.

Tannic Acid: Apply directly or dilute in water, soak the fabric, and allow it to dry before dyeing.

Each mordant will influence the final color tone.

Brown dyed with avocado

To dye with avocado, follow these steps:

Collect Avocado Pits and Skins: Use about 1-2 pits or skins from several avocados, 100 grs per 500 ml of water.

Prepare the Dye: Boil the pits and skins in water for 30-60 minutes until the water turns pinkish.

Strain the Dye: Remove the solid parts to get a clear dye solution.

Prepare the Fabric: Pre-soak the fabric in a mordant solution (like alum) to help the dye adhere.

Dye the Fabric: Soak the fabric in the dye bath for 30 minutes to an hour, stirring occasionally.

Rinse and Dry: Rinse the fabric in cool water and let it dry.

Yellow dyed with turmeric

Documenting experiments

When sodium hydroxide (NaOH) or hydrochloric acid (HCl) is applied to pH-neutral dyed fabrics, it can significantly affect the color.

Sodium Hydroxide: Increases the pH, often resulting in a color change to reddish-brown for dyes like turmeric due to the alteration of the dye's molecular structure.

Hydrochloric Acid: Decreases the pH, which can intensify the yellow color of turmeric by stabilizing its structure.

Both substances can shift the color properties of natural dyes, leading to different shades based on pH changes.

  • Hibiscus experiment

hibiscus experiment

When sodium hydroxide (NaOH) or hydrochloric acid (HCl) is applied to an acidic hibiscus dye solution, it alters the pH and thus changes the color:

Sodium Hydroxide (NaOH): Raises the pH, shifting the color from its natural pinkish-red (acidic) to a greenish or bluish tone (alkaline). Hibiscus is pH-sensitive, and alkaline environments produce significant color shifts.

Hydrochloric Acid (HCl): Lowers the pH further, often intensifying the reddish tones. The increased acidity deepens the red color, enhancing the natural hue of hibiscus.

Test

Material name Fabric composition Breathability Moisture-wicking abilities Heat retention abilities Stretchability Washing temperatures
Wool Animal fibers - sheep Highly breathable High Excellent Moderate Cool or warm
Cotton Plant fibers - cotton plant Highly breathable Moderate Low Low Warm

Results

wool cotton

Both wool and cotton can be dyed with muicle, but wool retains the color more effectively, resulting in a darker hue.
