What is eri silk?

Silk has been prized since ancient times. It is said that the beautiful Silk City was popular among the Roman women of 2000 years ago.

So how is silk produced? The answer is the production of the "Yamamayu moth," which uses mulberry as its staple food.

We focused on another type of silk. I was fascinated by the new texture of silk, which is different from the traditional silk.
Although it is silk, it has a bulge, is soft and light, and does not scratch. That is "Erisilk".
This time, we have succeeded in commercial development for clothing.

Silk, which is familiar to everyone, is created by the "silkworm moth" that uses mulberry leaves as its staple food, and is also called mulberry or domestic silkworm. However, there are more than 100,000 types of insects that make silk (silk thread insects) in the world. Among them, the ones that human beings use as fabrics other than mulberry silk are called “Wild Silk”.
We are promoting the incorporation of "Eri silkworm cocoon", which is a type of wild silk. We are making clothes by linking three production bases (Bang Methot or Bangkok, Vietnam), spinning (Bangkok), and weaving (Japan).
Why did you choose Eri silkworm in the first place?
Of course, its texture is outstanding, but Eri silkworm has various characteristics that traditional mulberry silkworms do not have.
I would like to explain below.

Eri silk cocoon
Compared to Mulberry cocoons, they are larger and have a fluffier surface. The shape of the mulberry cocoon is a bale or an ellipse, but the Eri silkworm has a long thin tip.
