Advantages of indigo dyeing for yarn dyeing

The dozens of indigo-dyed fabrics of Bingo-Fushiori are all dyed by looping threads called "KASE". The dyeing process is still the same as it was in the past, and it is still done by hand by craftsmen.

Indigo dyeing is a very delicate process, and the dye must be brought to the best condition each time depending on the temperature and humidity.
Craftsmen check the condition of the indigo every day and repeatedly fine-tune the solution so that the same color can be dyed at any time.


The indigo dyeing process of Bingo-Fushiori is roughly in the following order.

  1. Refine (boil) the yarn
  2. Drying the refined yarn
  3. Dip a piece of string into an indigo bottle
  4. squeeze the thread
  5. Let it air.
  6. Adjust the density according to the number of times the process 3 to 5 is repeated (in the case of dark blue, the process 3 to 5 is repeated a whopping 6 times).
  7. sun dry


The advantages of yarn dyeing instead of post-dyeing (product dyeing) are

  • Dyeing deep into the fabric
  • The color is hard to fade.
  • Enjoy changes asing


Personally, one of the interesting points about the indigo dyeing process is that the yarn looks dark blue when it is soaked in the indigo pot, but the moment it is lifted out of the bottle and exposed to air, it turns green.
This is due to the oxidation caused by the reaction between indigo and air, which is in an oxygen-free state in the dye.

When I see this phenomenon, I am reminded that indigo is a living thing.

One of the characteristics of this fabric is its warmth and sense of security, which mass-produced products do not have.
In this day and age, why don't you try to live a "life with indigo"?
