Our Biomass Materials

GREENWEAR currently processes/refines 10 kinds of biomass dyes to enable high-quality biomass dyeing.

Biomass Dyestuffs We Use

GREENWEAR uses only 10 of its many natural materials as biomass dyes.

Each dye has been a traditional dyestuff used by humans to make colors since ancient times

and has long been used as a natural medicine in East and Central Asia.

History of Natural Dyes

Natural dyes are traditional dyeing materials from the past. Until synthetic dyes appeared, humans used natural materials such as flowers, leaves, and pericarp to color their clothes.

It is not known when people began dyeing their clothes, depending on their origin and definition, but it is generally estimated that dyeing culture began naturally around B.C. 5000 around the world. In India, it is said to have started dyeing from indigo plants to blue, from madder roots to red, and from Lac in Arabia.


Advantages of Natural Dye

ZERO Synthetic Material

Because it does not use artificial synthetic chemicals, the effects on nature are minimal.

Eye-Friendly Color

Natural dyes contain a variety of pigments and organic substances in one dye. This creates a soft-colored wavelength curve to create a more comfortable and friendly color for our eyes.


Natural dyes are the most natural substances that humans have adapted for a long time. With little resistance to the human body, many materials were used as natural remedies in oriental medicine and folk remedies.

Limitations of Past Methods

Low Productivity

Traditional natural dyeing was not efficient because of low dyeing quality, such as fastness, and low production volume.

Color Limitations

Compared to synthetic dyes, the natural dyeing colors that can be realized were limited.

Water and Energy Usage

In traditional natural dyeing, dyeing/drying/cleaning processes were repeated many times to achieve the desired concentration and color.
