Fustic Powder Extract

Fustic Powder Extract, derived from Chlorophora tinctoria (commonly known as yellowwood or dyer's mulberry), is a natural, tannin-rich dye widely valued for its versatile and vibrant coloration on various fibers. This dye has long been a preferred choice for textile applications, particularly on natural fibers such as cotton, silk, and wool, due to its robust colorfastness and ability to produce luminous shades ranging from bright gold to olive greens. Historically significant, Fustic Powder was notably employed to dye khaki military uniforms during World War I, exemplifying its durability and rich tones.

Alfa Chemistry proudly offers a high-quality Fustic Powder Extract, ensuring consistent results for artisans, dye houses, and manufacturers seeking natural and sustainable textile dye options.

Achieving Golds and Beyond with Mordants

Gold Tones

When paired with an alum mordant, Fustic yields a bright, clear yellow on both cellulose and protein fibers. This traditional mordanting method emphasizes the dye's brightness and long-lasting qualities.

Extended Palette with Overdyeing

Fustic serves as an excellent base for creating secondary colors when overdyed or combined with other natural dyes:

• Khaki Green - Achieved by layering indigo over Fustic for textiles that require earthy, muted tones.
• Oranges and Olive Greens - By combining with madder, cochineal, or logwood, Fustic produces a range of warm, earthy hues that are particularly valuable for natural dyeing practices.

Dye Concentrations and Variations

To achieve optimal results with Fustic Powder Extract, we recommend using it at 10% on the weight of fiber (WOF) to obtain deep, rich gold. For paler, lemon-yellow tones, lower concentrations can be utilized. Additionally, Fustic exhibits an exhaust dyeing capability, allowing for efficient multiple-dye baths from a single solution, enhancing sustainability.

Advantages of Using Alfa Chemistry's Fustic Powder Extract

• High Tannin Content for Optimal Results: The elevated tannin concentration in our Fustic Extract allows for enhanced color uptake and longevity, especially on cotton.
• Consistency and Quality Assurance: Alfa Chemistry's stringent quality control guarantees that each batch of Fustic Powder Extract meets exacting standards, providing reliable and repeatable outcomes.

Application Guide for Fustic Powder Extract

To achieve consistent and vibrant results:

A. Preparation: Pre-wash the textile fibers to remove any residues that may interfere with dye uptake.

B. Mordanting: Apply an alum mordant to the fiber, especially for cotton, to enhance the brilliance and fastness of the yellow shade.

C. Dyeing Process: Dissolve Fustic Powder Extract in warm water and immerse the fiber, maintaining the dye bath at a stable temperature to optimize color intensity. Monitor the fiber until the desired shade is reached.

D. Exhaust Dyeing: After the primary dye bath, use the remaining bath for additional fibers or overdyeing to maximize resource efficiency.
