Technology for color matching dyeing with vegetable dyes

Abstract

The invention belongs to the technical field of vegetable dye dyeing and particularly relates to a technology for color matching dyeing with vegetable dyes. A special auxiliary is added, the dyeing environment (the pH of a dyeing solution) is controlled, and then vegetable dyes are matched and then used for dyeing fabric, so that the influences of sugar and pectin remaining in the natural plant dyes on diffusion of different dyes and the nonuniform dyeing generated after color matching of the dyes are avoided. By using the technology for dying, the color of the fabric is very pure, a good dyeing rate and excellent fastness are achieved, and the damage of organic chemical dyes to the skin of the human body is avoided.

Description

Technical field [0001] The invention belongs to the technical field of dyeing with vegetable dyes, and particularly relates to a process of using several vegetable dyes for color matching and dyeing. Background technique [0002] The basic colors that can no longer be decomposed are called primary colors. The primary colors can be combined with other colors. Generally speaking, the three primary colors, namely red, green, and blue, can mix all colors. [0003] In recent years, as people's awareness of environmental protection has increased, they have gradually realized that chemically synthesized dyes have caused serious damage and destruction to human health and the environment. Plant dyes refer to the use of natural flowers, grasses, trees, stems, leaves, fruits, seeds, barks, and roots to extract pigments as dyes. Plant dyes are non-toxic and harmless, and will not cause any harm to human health; the dyed fabrics are natural in color and durable; they have anti-insect and antib...

Problems solved by technology

[0006] However, due to the special source of plant dyes, the prepared dyes contain a certain amount of sugar and pectin. Even through the purification operation, some sugar and pectin will remain in the dye product. This is why plant dyes are different from conventional dyes. A big difference between chemical dyes, sugar and pectin will affect the diffusion of dyes in the dyeing process, and the degree of influence on different types of plant dyes is different, so when using several plant dyes to match the color of the fabric When dyeing, the diffusion of each primary color dye will be affected by sugar and pectin, resulting in different effects of each primary color on the fabric, thus failing to achieve the expected dyeing effect
