Mimosa Hostilis Root Bark Powder (MHRB) – Natural Textile Dye

About Mimosa Hostilis Root Bark Powder (MHRB) – Natural Textile Dye

Mimosa Hostilis inner root bark powder (MHRB) is finely milled Brazilian botanical material from Mimosa tenuiflora, widely known as Mimosa Hostilis. This inner root bark powder is offered for natural textile dyeing, fiber arts and botanical craft applications. It can produce earthy reds, reddish browns and burgundy-inspired tones, with results varying according to fiber preparation, concentration, water chemistry, mordant and dyeing method.

Which fabrics can I dye with Mimosa root bark powder?

Our Brazilian Mimosa Hostilis inner root bark is supplied as a convenient powder for makers working with cotton, linen, silk, wool and other natural fibers. Because botanical color varies naturally, testing a small swatch before a larger project is recommended. Thorough scouring helps prepare the fiber, while alum can be used as a mordant when appropriate for the chosen material and process.

Mimosa tenuiflora is the botanical name associated with the material also widely known as Mimosa Hostilis root bark. Keeping notes on fiber weight, powder quantity, preparation, temperature and processing time can make later dye sessions easier to compare and reproduce.

What colors can Mimosa root bark produce?

Mimosa Hostilis inner root bark powder can develop earthy red, reddish-brown and burgundy-inspired color on suitable natural fibers. Lighter or deeper results can be explored by adjusting the amount of Mimosa Hostilis inner root bark powder relative to the dry fiber weight and by changing preparation and processing conditions. The product is intended for traditional and experimental textile dyeing and botanical craft projects.

What sizes are available?

Choose 50 g, 100 g, 250 g, 500 g or 1 kg of Brazilian inner root bark powder for sampling, individual projects or larger dye sessions.

How to plan a natural-dye project

1. Choose a complete method. Match the botanical material to your fiber and intended color.
2. Prepare and test. Clean the textile and use the fiber-specific preparation, tannin or mordant process where required by that method.
3. Prepare the dye bath. Follow the method for extraction, filtering, quantities and temperature; not every botanical material uses the same sequence.
4. Dye a sample. Record the dry fiber weight, preparation, material quantity and processing conditions.
5. Finish and evaluate. Follow the selected method for rinsing and washing. Compare the dry sample before dyeing a larger piece.
