What is natural dyeing
We use natural dyestuff extracted from plants and animals like trees, flowers, and etc. We’ve been developing optimum recipe to minimize the consumption of chemicals and energy. The colors of natural dyeing look like nature, so they are very beautiful and comfortable.
What is natural dyeing
• A chemical dye, as a substance of the refined dye, or as a mixture, it can make sharp, intense colors, and maintain the colors as well.
• On the other hand, the majority of the natural dyes contain various components because this is natural material. Therefore it is difficult to maintain a vivid and leveling color. And most are represented by 'earthy color tone‘. (But, Indigo and gardenia are exceptional, they can be relatively bright colors.)
• The ingredients of the natural dyes have effects on the plantations and the climates. This means that even if the dye stuff are the same, the color differences can occur.
