How to handle Natural Dye Thread & fabric

The soft color from the natural dyes is significantly different from the vivid color with chemical dyes. We enjoy the color of Natural Dye Sashiko thread, especially in a process of making “Boro” so that both fabric and thread can age – change color – together with overtime. We repeatedly tested the color stability, either if the color fades out by washing, before introducing them online. However, the Natural Dyed & Hand Dyed Sashiko thread & fabric require some attention and understanding of how to handle. The color will not be washed away by regular care for the natural dye. However, we do not recommend to throw them to the washing machine with detergent (which may have kind of “bleach” in it). Here, we introduce how to handle Natural Dye Thread and Fabric.


“Don’t” do list | Handle Natural Dye Thread with care.

First of all, please never use “Bleach” in washing and to handle Natural Dye thread. One wash with bleach may (and most likely “will”) completely wash away the natural color and make it bright white. The bleach is strong enough to do its job – to make it bright white.

The point we have to pay attention here is that some of “regular detergent” may contain the same chemical as the bleach in it. For example, if a detergent say “stain removal”, then the detergent may be too strong for the Natural Dye color.

Also, putting the Natural Dye thread and fabric in the water with detergent for a long time is not a good idea. The more time the color touches the detergent, the more color may be washed away.


Do list | How to well Handle Natural Dye Thread

Generally speaking, the natural dye doesn’t go well with the chemical detergent. In need of using the detergent, please choose the “Neutral Detergent”. Although it is quite easy to find them in Japan, I do not find the neutral detergent easily in the US (we can find them but quite expensive). In that case, please try to find the “gentle” or “soft” detergent and make sure to test the thread and fabric if the color will be washed out or not. In my experience, most of the color will stay on unless the detergent is “gentle” and washed gently. However, as a baseline, please handle Natural Dye thread with maximum Care.


Super beautiful color from nature. Although the core enjoyment of natural dye is to enjoy the color change, it is so sad to lose the color.

Summary of Do and Don’t

Do:

  • Hand-wash with no detergent. Or gentle wash with Neutral Detergent.

Don’t:

  • Using Bleach, or strong detergent which may contain Bleach.
  • Machine wash with long-cycle (or extra wash cycle).
  • Leave the thread or fabric in water (with detergent) for a long time.


Understand the reaction process

It is probably difficult to find a “Natural Dye” items in the mass-produced market. It is because the process of natural-dye requires a lot of attention and care. The color from nature will not stay on the thread or fabric by dipping them into a vat. It isn’t like a watercolor, putting paint on the paper.

The natural color stays on the thread and fabric by chemical reaction with a catalyst. We usually use the metal, such as iron or copper, to make the reaction happen. In another example, the Authentic Japanese Indigo Dye (Hon-Aizome), they use the oxidation process to create such a beautiful blue. The fabric and thread right after dipped in the vat looks somewhat “gray” or “brown”. In a process of oxidation (touching the air that contains oxygen), the beautiful Japanese blue comes out.

The chemical reaction doesn’t mean using chemical materials. Here, chemical reaction equals to Oxidation and Reduction. Vinegar will make the liquid more acidic and ash (such as wood ash) make the water more alkalinity. Either of acidic and alkalinity affects the balance of Natural Dye and could end up with washing out the color or changing the color.

Therefore, we strongly recommend using natural detergent, or just water.


The natural dye before the Industrial Revolution

One of the big reasons we use the Natural Dye thread is to recreate the beauty of Japan in hundreds of years ago – before the industrial revolution. Back then, in Japan, they did not have the chemical (artificial) detergent or bleach to wash the fabric. They did not have a washing machine either.

Instead, they washed the fabric and thread by hands with care (attention). I hope you would do the same when you handle Natural Dye thread and fabric.

By the way, this is my personal endnote (which may contradict what I had written so far). Anyhow, I DO wash my Sashiko Stitched Denim with the gentle detergent in a washing machine… I had washed probably more than 100 times over 1~2 years, but I can still see the thread color. The yellow from mountain peach looks more like white, but it still has yellowish color (I believe). I always wash it separately, with a gentle cycle of the washing machine, with a small amount of detergent as I feel. I sometimes do not add the detergent, but at some point, the jeans get smelly that we need some detergent… I hope you can find your own way to handle Natural Dye thread and fabric.

A sheet of carbon paper is necessary to prepare the pattern on the fabric before Sashiko stitching. One side is coated with a colored chalk and you can transfer the pattern by using a ballpoint pen or a dressmaker’s tracing wheel.


【Update】

Starting Feb.2020, we started carrying another brand Carbon Paper (Cosmo). In our experience, the quality is even higher than previous brand, and we enjoy the results. Please read the direction at the end of this page (It is the translation of Japanese instruction on the package).


Cosmo Carbon Paper:

3 sheets of about 35 cm x 26cm. It is more costly per sheet, but the result is more satisfactory in my experience.


Clover Carbon Paper:

5 sheets of 30cm x 25cm Chakopee papers are in one package. (The size of one sheet is about 12-inch x 10-inch). There is a great color variation.


How to use the Chalk Paper

  1. Place the fabric (usually backside facing up).
  2. Place the shinning side of Carbon Paper facing to the back of the fabric.
  3. Layer the Mylar Paper (Cello Paper)
  4. Put the pattern paper (any paper is fine).


Please check the online tutorial for the whole process.

+++++ Notes on using the carbon paper +++++
Please read it before you use it (Disclaimer).
  • - Please try to use a small piece of fabric (which you plan to use) and the corner of this paper to test if the pattern washed off as you wish. Please wait until the pattern gets dried thoroughly, and test it.
  • - When you erase the pattern, please avoid using the Oil-based solvent such as Benzine.
  • - If you iron the fabric before erasing the pattern, the pattern may stay stronger and get more difficult to be washed away. Please be careful with that. (For Cosmo, please do not iron until you wash away the pattern completely).
  • - If the pattern does not get washed away by just water washing, please try to wash with neutral detergent by hand. You may use a small brush (like a tooth brush) to scrub it off. Please avoid dry clearning.
  • - You may experience the difficulty of transferring the pattern onto the thick and bouncy fabric such as felt. (The thick and bouncy fabric isn't ideal for Sashiko.)
  • - After usage, please keep the paper in the bag, and avoid the high-temperature &high-humid condition and direct sunlight. Please reach out from children's reach.
  • Too much pressure may penetrate the ink to the deeper fabric and make it difficult to wash it away. Please try & practice with small piece. (When you use Mylar paper, you may not need to worry about the pressure since Mylar paper is quite thick).
