We here at ten-i muhou intend to use naturally derived dyes and mordant as much as possible for dyeing cotton and yarn products so you can also enjoy selecting colors.
There are two typical dyeing methods: natural dyeing and red iron oxide dyeing.
In natural dyeing, color varies from batch to batch even using the same plant variety.
On the same principle that every naturally ripened apple has a unique color, the variation in dyed color is proof of non-chemical processing. The color will fade over time, developing a distinctive beauty.
The natural dyes we usually use are: Gardenia jasminoides, Rubia akane, Myrica rubra, pomegranate, scale insect, logwood, and Rhus javanica.
Red iron oxide dyeing
We also use red iron oxide dyeing. Red iron oxide is the main component of the earthfs crust. It has long been used throughout history, even in the decoration of Jomon and Yayoi pottery, and as the red of the evil-repelling red charm in Takamatsuzuka Tomb, and in older times, it was used in the Paleolithic cave paintings in Lascaux, France, and Altamira, Spain. It is one of the oldest and the most familiar non-toxic dye materials, which made the development of mankindfs color painting culture possible, and can be collected from soil anywhere in the world.
Early modern period in Japan, in the middle of the Edo era, there were many jobs available helping carpenters in the Minamikawachi region (southern Osaka), and one of such job was painting with red iron oxide. In this area, it was called "bengarah "(gk), which was used as a dye for clothes and a textile called Kawachi cotton as well as in architecture, and it soon spread throughout the area.
Red iron oxide dyeing at ten-i muhou is a collaboration with dyeing specialist, Tomehiko Nakajima, a magician with color who reproduced the beauty of the old Minamikawachi dyeing method colors in the textile industry using modern pigment grinding process techniques.
Other natural dyeing methods include Hanizome dyeing by Taishoboseki Industries (using soil), Rakuyozome dyeing (plant dye), and reactive dyeing, which meets the strict requirements for environment and safety standards by GOTS.
