Problems solved by technology

In the printing and dyeing process, a lot of synthetic dyes are needed. Using natural dyes to dye textiles requires multiple use of modifiers and dyeing auxiliaries. The process is complicated and the cost is high. Most of the modifiers contain heavy metals, which are harmful to the environment and The harm to the human body is relatively large, and the dyeing effect is not good, and there is often fading and uneven dyeing

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and specifically refers to a green and efficient ecological printing and dyeing method. Background technique [0002] Printing and dyeing is a combination of physical and chemical treatment of textiles, such as adding patterns and patterns to textiles, changing the color of textiles and related pre-treatment processes, etc., through physical or chemical changes between dyes and fibers , will make the textile have a certain color and gloss. According to the different printing and dyeing objects, the printing and dyeing process can be divided into cotton textile printing and dyeing, linen textile printing and dyeing, wool textile dyeing and finishing, silk printing and dyeing, etc. China's printing and dyeing industry is developing rapidly, processing The capacity ranks first in the world, and it is already a major textile printing and dyeing country. In the printing and dyeing process...
