Natural Dye the colors from nature

Although clothing dyed using natural, vegetable dyes have been drawing attention for many years, there have been many issues associated with it, such as it being vulnerable to sweat and light, changing in color when washed, and the inability to industrialize it - manufacturing only one piece at a time by hand.

Chori, in cooperation with our subsidiary Chori MODA Co., Ltd. which undertakes product planning, and CIHON TEX CO.,LTD a dye processing venture company, have improved vegetable dyeing to create Natural Dye, a new natural dyeing method that achieves superb fastness. This has allowed us to industrialize natural vegetable dyeing.

This is a new hybrid dyeing technology that takes natural colorings from plants, vegetables, fruits, and residues (used coffee grounds, etc.) and colors textiles by fixing the dyes to textiles using naturally derived substances. Approximately 3,000 types of colors can currently be expressed and a significant characteristic of this technology is the ability to dye not only natural materials but also synthetic textiles as well. In addition, this is an eco-friendly dyeing method that contributes to preventing water and soil pollution due to the fact there is only an extremely minute amount of leftover pigments in the wastewater.

In 2009, Chori introduced the Vegetable Natural Dye series, which utilized imperfect vegetables. Clothing and yarn dyed using natural pigments extracted from various vegetables such as tomatoes, carrots, onions, and others attracted attention in the market as ecological products.

In 2012, through a collaboration with Shikibo Ltd, a cotton-spinning company, Chori announced the Natural Dye COOL, made using contact cooling sensation materials, and the TOP Natural dye, with characteristic unique mixed colors, which are dyed while still in its cotton form.

In addition to sales to apparel brands and corporate uniforms, Chori currently engages in the sales of event and campaign sales promotion items such as t-shirts and towels, as well as products for corporate novelty items. Furthermore, we are currently considering expanding our sales outside the domestic market to countries such as the United States, with high environmental awareness.
