Compared with cotton, silk fabric can be trickier to dye, for silk is a protein-based fiber. In order to add long-lasting color, you have to open the cuticle of the silk fiber, thus dye can reach the shaft. Cooling is also important. You must gradually change the temperature. Note: temperature should not be overheated. Otherwise, fiber will get damaged.
Things you need to do
- Wet silk fabric to saturate it, helping color more easily adhered to the fiber.
- Mix dye solution in a dye pot and then add the fabric. Slowly raise the temperature to 120 degrees, and stir the fabric frequently.
- Add vinegar to the pot. Maintain the temperature for at least five minutes, depending on the instructions on the dye box. Continue to stir the fabric.
- Raise the temperature to a full simmer, and let it simmer for at least five minutes with stirring frequently. Turn off the heat to let it cool completely.
- Remove the fabric. Dry flat.
If you don’t want to hand stained, you should use some tools to dye.
