[0002] With the rapid development of economy, people have higher and higher requirements for things other than food and clothing. In the field of textiles, consumers begin to pursue green, natural and harmless textile fabrics, which puts forward new requirements for the preparation of dyes. In recent years, plant dyes are popular among consumers because of their green and environmental protection. However, the preparation process and coloring method of existing plant dyes are immature, the exhaustion rate of dyed cloth is low, the color fastness is poor, and the concentration of wastewater dyes in the dyeing vat is extremely high, which is a huge burden for both enterprise processing and direct discharge to the environment. In addition, when plant dyes are used for coloring in the prior art, acrylic, nylon, wool, silk, modal and other fabrics all need a dyeing temperature of 135°C or even higher. How to prepare plant dyes and processes that can be used at low temperatures and have high color fastness, high exhaustion rate and low pollution is a problem that enterprises should break through now.
