Kakishibu dyed linen yarn comforter case



Kakisibu (Persimmon tannin) dyeing is done by fermenting persimmon(kaki) juice before it ripens


A textile of natural origin


Linen meets kakishibu dyeing(persimmon tannin dyeing).

Linen, a yarn from flax grown in Europe, and kakishibu dyeing, a traditional Japanese process of fermentation, meet at Tenjin-factory and become a woven fabric.

Linen made from flax, which grows only with rain and soil, has benefited mankind throughout its long history. It has enabled us to live comfortably on this earth through its natural water absorbency, quick-drying, breathability, and heat retention properties without human intervention.

On the other hand, traditional Japanese persimmon tannin dyeing, so-called kakishibu zome, is a natural dye made by fermenting the juice of astringent persimmons. Because of its film-forming properties, it has long been applied to clothing, paper, wood, and other materials to strengthen them and make them last longer. It is the fruit of the wisdom of our ancestors, who wished to use this finite natural resource with care and longevity.

Kakishibu dyeing comes from a plant called kaki fruit and linen also comes from  a plant called flax. Both are plant-derived materials and they harmonize well with each other to create a unique texture and color. It can be said that this is truly a one-of-a-kind linen fabric.

First of all, the texture has a moderate firmness that feels smooth to the touch, and even when sweaty, it does not become sticky in a strange way. It is a reliable ally that supports comfortable sleep.

Its color is also attractive. At first they are a beautiful persimmon color, but as they are washed and dried outside in daily life, the color deepens or, conversely, fades, revealing a mysterious world of colors. We who have become accustomed to chemical dyes are at first bewildered by this, but it reminds us that this is the nature of naturally occurring materials. Nevertheless, since color migration does not occur, this product will not stain other clothing, etc., so you can use it with peace of mind.

In general, we have the impression that natural fibers are weak against friction, but kakishibu-dyed linen is so strong that it overturns this common sense. This is one of the charms of kakishibu dyeing.

Please try such an attractive kakishibu dyeing comforter case and see for yourself.

Enjoy color changes of Kakishibu dyeing

Traditional Japanese persimmon tannin dyeing ( kakishibu-dyeing ) is a natural dye made by fermenting the juice of astringent persimmons. The yarn is soaked in this solution, dyed, washed, and dried, and then carefully repeated over and over again to achieve the beautiful persimmon color. The main ingredient of the color is persimmon tannin. This persimmon tannin reacts with various components to produce a darker color. On the other hand, it is also decomposed by light and heat, resulting in a lighter color. In other words, when persimmon tannin is washed for the first time in daily life, it reacts with water and detergents, resulting in a darkening of the color. After repeated washing and drying, at some point, the color begins to fade (lightening). The Japanese have long enjoyed this transition of color. The fading and changing of colors is quite natural and is a proof of the use of natural materials.

Kakishibu dyeing, with these characteristics, does not cause color migration, and there is no need to worry about staining other clothes when washing. It is also  durable against friction. Kakishibu dyeing is attracting attention as an environmentally friendly dyeing method.





Fading begins with increased washing frequency and color fades.


   Colors dyed with great care will not migrate


Selvedge, a sign of good quality


 We started weaving on old-fashioned analog shuttle looms with the aim of returning to the humanistic approach to manufacturing that has been lost due to mass production and mass consumption. Shuttle looms are like hand looms powered by electricity. It still requires human hands to make cloth. The advent of the latest looms, which require as little human labor as possible in the name of labor saving, has certainly realized mass production, but on the other hand, the cloth-making site where the warmth of hands still remains has disappeared. Tenjin-factory was born as a textile factory where people make cloth and the loom is only a tool.

The shuttle loom is characterized by its ability to weave without putting a load on the threads, making it possible to create soft, nostalgic, and warm fabrics. Its charm also lies in the fact that it produces a linen fabric with a selvedge, just like antique linen. In the process of weaving the cloth, parts called selvedge are formed at both ends.  Traditionally, selvedges have been marked with colored threads so that people can tell who made them. This has somehow become a part of the design. Tenjin-factory also weaves original selvedges into various linen fabrics.

Selvedge is a sign of good quality.






The part seen at the edge is called selvedge  



Selvedge is a marker of  Tenjin-factory's textiles


The tool used to weave without loading the yarn is called a shuttle


What is the comforter case made of selvedge fabric?


In order to accommodate various sizes from different countries, Tenjin-factory's bed linens are joined together at this selvedge. The thickness of this part is half that of the main part so that it does not become thicker when overlapped. So the overlapping areas will not cause you discomfort.

   To make your own comforter case


This product is made to order.

Please allow for up to 90 DAYS to make the comforter case for you.

We dye your yarn with persimmon tannin after receiving your order. First, the weaver himself dyes, washes, and dries the linen threads several times until they reach a deep and beautiful persimmon color. The process takes about a month and a half, depending on the weather. Next, the beautifully dyed threads are hung on an old-fashioned shuttle loom, and skilled weavers weave them into cloth. The woven cloth is then cut and sewn by hand. Finally, the cloth is inspected and ironed by our veteran staff before finally being completed. Kakishibu dyeing is a natural process, so the color of the finished product is a once-in-a-lifetime occurrence. In this way, your own comforter cover will be created. Please look forward to its arrival.





Dyeing over a number of times will gradually darken the color.

How to care persimmon tannin-dyed products


1. Avoid light.

Do not leave the product exposed to sunlight or electric lights for long periods of time.
When drying, dry in the shade.
When storing, choose a place where light does not penetrate, or wrap the product in a cloth.



Wash it in a way that reduces friction. If using a washing machine, please put it in a net and wash it alone.



Use a mild alkaline detergent. Do not use detergents containing bleach or optical brighteners. Also, please avoid using fabric softener.


4.Water temperature

We recommend room temperature water for washing. The higher the temperature, the more easily the color will dissolve in the water.


5. Ironing

Avoid creasing the fabric, as this may cause the corners to fade.



Please use delicate mode. Otherwise, it may cause shrinkage.
