Problems solved by technology

The existing plant dyeing is still based on the traditional dyeing process of pigment extraction, not only the dyeing time is long, the color fastness is low, but also the cloth after dip-dyeing is very heavy, and the workload of the workers is huge, and the cloth in the existing dip-dyeing method is folded with each other, and the folding marks are very Obviously seriously affect the dyeing effect, how to improve the technical level of plant dyeing has always been the object of research by those skilled in the art

Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 and figure 2 , a kind of plant dyeing method based on yam yam comprises the following steps:

[0020] 1. Mix starch, cellulose, sodium alginate, and chitosan with crushed yam to form a dye. The weight ratio of each component in the dye is 30:1:1:1:1, and then the concentration of the dye is 25%. ethanol solution for the first extraction;

[0021] 2. Filter the first extracted solution;

[0022] 3. Put the filtered solution into 25% eth...

Abstract

The invention discloses a plant dyeing method and device based on dioscorea cirrhosa. Starch and cellulose are adopted to fix, separate, and lock pigments in dioscorea cirrhosa. Sodium alginate and chitosan are taken as a biological thickening agent to increase the solution viscosity to form macromolecular hydrophilic groups so as to further peel the pigment molecules; finally ethanol is taken as an extracting agent to extract pigments by a centrifuge so as to form a liquid dye, the process is environmentally friendly and pollution-free, and the dyeing process is achieved in a dyeing tank. The dyeing method and device have the advantages that the dyeing efficiency, the pigment extraction performance, and the color fastness of dyed cloth are greatly improved.

Description

technical field [0001] The invention relates to the technical field of dyeing technology and equipment, in particular to a plant dyeing method and device based on yam yam. Background technique [0002] At present, with the improvement of people's living standards, chemical dyes are mostly used in fabric dyeing, but most of the chemical dyes are synthesized from petroleum. These products can decompose more than 20 kinds of carcinogenic or allergenic substances during production. Azo dyes and under certain conditions can also dissociate heavy metal ions harmful to human body and environment such as lead, chromium, pickaxe, diamond and mercury. Therefore, we use plant dyes as much as possible for dyeing. Plant dyes come from the plant world, grow with plants, and die with plants, which is very environmentally friendly and healthy. The existing plant dyeing is still based on the traditional dyeing process of pigment extraction, not only the dyeing time is long, the color fastne...
