Article: HOW TO DYE


Here we will explain the actual dyeing process for STUDY MADE backpacks.

Here's what you need to prepare:

  1. Dye ( 2 coal dyes )
  2. Color fixing agent ( Mikanol )
  3. Pot (size pot inner diameter 36cm)
  4. ball
  5. Salt (120g)
  6. neutral detergent
  7. cassette stove
  8. rubber gloves
  9. chopsticks

The bigger the pot, the better, but here I bought a sundou pot. Since it is expensive, you can purchase it cheaply from auction sites.

The amount of dye used varies depending on the manufacturer, but 20g of the dye used here can dye a total of 250g, so if the weight of the backpack is 530g, I decided to use 2 dyes.

This is the dye maker I used this time.

Dyeing procedure

1 Wash with water

Open your backpack, remove the bag hanging inside, and wash it with water.

2 Dissolve the dye

Add 40g of dye to 1 liter of boiling water and dissolve thoroughly.

3 Make the dye solution

Pour water into a 12 liter pot and heat it on the stove (we used water at around 40 degrees Celsius, close to the temperature of a bath). Add the previously dissolved dye and 120g of salt into it and stir.

4 Dyeing

Place the washed backpack into the dye solution you made. At this time, unevenness can be controlled by adjusting the amount of stirring. If you want to dye it evenly and evenly, stir it thoroughly. (about 30 minutes)

5 Wash with water

Take out your backpack and rinse it with water.

6 Wash with detergent

Wash with lukewarm water using a neutral detergent

7 Rinse

Rinse until there are no bubbles left

8 Perform color fixing

Fill a pot with about 10 liters of water, add 5 capfuls of Mikanol, stir, then put your backpack in and soak for about 40 minutes.

9 Rinse

rinse with water

10 Dry in the shade

Dry thoroughly

*This is a dyeing video from the dye manufacturer used this time. The above process was performed almost the same as in the video.

It took about 2 to 3 hours, excluding drying time. Other than the size of the pot, I think it was easy to dye, and it turned out better than I imagined. You can also tumble dry it by turning it inside out and putting it in a laundry net. Those who want to create wrinkles and areas may want to try it. Please come and complete your own authentic bag!

The larger the pot, the easier it is to dye, and the better the finish will be. It's a bit of a hurdle, but I'd appreciate it if you could prepare a large pot.

・Not only dyes, but coloring materials are sensitive to sunlight fastness (this is more noticeable when used at home because unlike industrial dyeing, strong chemicals are not used) . We recommend re-dying when the color fades.
