To fix natural plant dye, especially on plant-based textiles like cotton and linen, you need a fixative to prevent the color from fading quickly. Salt is a commonly used fixative.
Using Salt as a Fixative
Here's how to use salt to fix natural plant dye:
- Fabric Type: Salt works best on cotton fabrics, threads, and yarns.
- Ratio: The ideal ratio is 1 part salt to 16 parts water.
- Process:
- After dyeing, prepare the salt solution using the correct ratio.
- Submerge the dyed fabric in the salt solution.
- Allow the fabric to soak for a period of time. The exact time may vary depending on the specific dye and fabric, but typically 30 minutes to an hour is adequate.
- Remove the fabric and rinse thoroughly with cool water.
- Dry the fabric as usual.
Why Salt Works as a Fixative
Salt helps the dye molecules to bond more effectively with the fabric fibers. This process increases the colorfastness of the dyed material, preventing the dye from easily washing out.
| Fixative | Fabric Type | Ratio | Method |
|---|---|---|---|
| Salt | Cotton, Linen | 1:16 | Soak and Rinse |
By following these simple steps, you can effectively fix natural plant dyes and ensure your creations retain their color for longer.
