MAITO dyes its products using "natural dye". We generally call it "Kusaki Zome" because it is easier to understand, but it is sometimes called "vezitable dyeing", "eco-dyeing", or "plant dyeing". As the name implies, in the case of "natural dyeing," the dyes are extracted from plants and trees. Some dyes are derived from insects, such as cochineal and lac bug. What they all have in common is that they are not artificial and chemically synthesized dyes, but dyes extracted from natural sources.
Since herbal dyeing uses boiled and roasted plants, it is unlikely to cause environmental damage unless the hot water is discharged into a river, etc. Synthetic dyes are considered a cause of environmental pollution, and in Japan, the establishment of water purification facilities has recently become a regulation. Since dyeing with plants and trees does not discharge harmful dyeing wastewater containing chemical substances, i
t can be said to be a dyeing method with less environmental impact.
