Indigo dyed fabric manufacturing process and washing method, etc.

Koshibu's indigo dyeing fabric

The fabric used in our shop does not use chemical dyes, etc.

The process of dyeing , washing , and laying down is repeated many times until the inner part ( core ) of the thread becomes deep indigo.

Discoloration and dye transfer will always occur when washing or if there is friction.

However, basically, if you wash the person with the color transfer several times, it will return to its original state.

However, please note that rubber and leather products will not come off if the color is transferred.

Indigo dyeing does not change color by washing, but it oxidizes and gradually changes when it comes in contact with the air.

Therefore, it is different for each person depending on how to wear it and how to handle it ( preservation method ) .

By all means, please enjoy the changes as clothes that you can grow yourself.

Basically, I don't use a lock sewing machine, and even when washing, I use a method that involves the seam allowance so that I can wash it.

I finish it as strong as possible. ( Sometimes I use a lock sewing machine because of the design )

You can wash it in the washing machine using water below 30 ° C and a neutral detergent (bleach is not allowed).
(If you have a laundry net, please use it.)
For soaking, use water mixed with a neutral detergent and do not soak for more than 10 minutes.
(In the case of powder detergent and solid detergent, please be careful to dissolve it properly in water so that no lumps remain.)
