Strictly speaking, the dyes that can meet the above requirements should be called environmental friendly dyes. In addition to meeting the above requirements, the real environmental protection dyes should be environmentally friendly in the production process, and do not produce "three wastes". Even if a small amount of "three wastes" are generated, they can be treated by conventional methods to meet the national and local environmental and ecological requirements.
