Weaving

Dark blue dyed with the indigo plant

The leaves of this plant contain a blue dye

It is called Tade-Ai

Fermented leaves called SUKUMO

The blue dye in this product is not soluble in water as it is

Therefore, we make the lye, which is a strongly alkaline water

Putting SUKUMO into the lye to make dyeing solution

Blue dye is dissolved in the lye with the help of microorganisms called reducing bacteria

Wheat bran, shellfish ash, etc. are added as needed to energize the reducing bacteria

Temperature control is also important because they are living creatures

Dyeing solution will be ready after about 10 days

In the water, the cloth is dyed orange, but when it comes into contact with air, it begins to oxidize

At first it turns yellow, and finally a beautiful blue

We dye in the yarn state

Repeat a number of times from lighter to darker colors.

About linen

Flax that grows only in the rain and soil has benefited mankind throughout its long history. It has enabled us to live comfortably on this planet through its natural water absorbency, quick-drying, breathability, and heat retention properties without human intervention.

The flax plant is a versatile plant, from the seeds of which linseed oil can be extracted, and from the stalks of which fiber for weaving can be obtained. Because of these characteristics, it is considered an excellent agricultural crop, and its cultivation seems to have flourished even in ancient Egypt. Today, Europe is the main producer of flax for textiles, with France, Belgium, and the Netherlands accounting for 85% of total production.

The fiber is extracted from the inner part of the stem, which has hollow pores. These hollow pores allow water and perspiration to soak in easily, enhancing water absorbency, while at the same time allowing it to dissipate and dry quickly, keeping the skin feeling dry and smooth without being sticky. On the other hand, when you feel cold, air warmed by your body heat enters the hollow pores to keep your body warm. In other words, linen can be used comfortably throughout the year.

In addition, linen can be washed repeatedly. Each time you wash it, the texture will soften, feeling even better.

Linen is a pleasure to use.

About Indigo-dyeing

Tenjin-factory's indigo dyeing process is based on the traditional Japanese method of lye fermentation), which is carried out by skilled indigo dyeing masters. The process of making the dye solution used for indigo dyeing is called "akuhakkodate" in japanese. It means lye fermentation.  Indigo dyeing is a process in which the dye solution is made using only natural ingredients. They raise a bacterium called "reduction bacterium" as if it were their own child, and change indigo, the source of blue color which is normally insoluble in water, into water-soluble. To energize the bacteria, several sources of nutrients are provided. They too will be all natural. The dye solution made in this way is so safe that it can be spread on fields as fertilizer after it has served its purpose. Linen yarns dyed by carefully repeating the process of dyeing => washing => drying over and over again with such safe dyeing solution are woven into sheets. The indigo dyeing process, which is carefully carried out using traditional dyeing methods, does not cause color migration, so there is no need to worry about staining other clothes when washing.

About Tenjin-factory's fabrics

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.

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 the 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. In addition, as with antique linen, the selvedge itself is part of the design of Tenjin-factory's selvedge linen. This comforter case is made from fabrics that will be antique in 100 years.

How to care indigo-dyed products

1.Avoid light

Do not leave indigo-dyed products exposed to sunlight or electric lights for long periods of time.

When drying, hang it in the shade.

When storing, choose a place where it will not be exposed to light, or wrap the product in a cloth.

　　

2. Dealing with scum

If not washed for a long period of time, the fabric may take on a slightly yellowish tinge. If this happens, rinse with water to remove the yellow tinge. Leaving it as it is may cause the color to fade.

　　　

3. Washing

Please wash in a way that is less likely to cause friction. Hand washing is recommended, but if using a washing machine, be sure to put the garment in a net and wash it alone. For the first 3 months or so, the blue color will appear in the water and may stain other items. After that, the indigo dye will set in and the blue color will no longer appear.

　　

4. Detergent

Please use a neutral detergent. Please avoid using detergents containing bleach or optical brighteners. And also please avoid using fabric softener. Since indigo easily dissolves in alkaline solution, please avoid soap as much as possible. If you have no other choice but to use it, please keep the soaking time as short as possible.

　　

5.Water temperature

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

　　　

6.Color Migration

For the first 3 months or so, the blue color will appear in the water, so please wash the product alone. If color migration occurs, it can be removed by washing immediately with soap or other alkaline detergent and then rinsing in water.

　　

7. Ironing

Please avoid creasing the fabric, as this may cause the corners to fade. To avoid color transfer to the ironing board, we recommend placing a cloth between the product and the ironing board when ironing.

　　

8. Dryer

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