Application of nano-biocolorants in Yao nationality patterns

Nanobiodyeing refers to an innovative process of dyeing by extracting pigments from various pigment-containing organisms in nature and processing them with nanotechnology. No or very few chemical additives are used in the dyeing process. The excellent color culture of natural biological dyeing should be given new meaning so as not to cause a break in traditional skills. Natural biological dyes are non-toxic and harmless, non-allergenic and non-carcinogenic to the skin. They have good biodegradability and environmental compatibility. Their colors are soft, natural and distinctive. At the molecular level, the application of nano-bio-pigments can involve the molecular structure and interaction of the dyes used in Yao patterns. Through biomolecular design, we can develop nano-pigments with specific colors and stability. These pigments can better integrate with the natural fibers in Yao patterns, providing more vivid and lasting colors.
