Abstract

The invention discloses a method for preparing a plant dye with lonicera edulis. The method comprises the following steps: lonicera edulis is placed in water and is prepared into lonicera edulis pulp; the lonicera edulis pulp is subjected to first filtration, and a filter residue A and a filtrate A are collected; the filter residue A is placed into an extraction device; anhydrous ethanol is added, and the mixture is stirred; after stirring, second filtration is carried out, and a filtrate B is collected; the filtrate A is mixed with anhydrous ethanol, such that a mixed liquid 1 is obtained; the mixed liquid 1 is heated and well mixed by stirring, and is allowed to stand for 8-24h; the mixed liquid 1 is subjected to third filtration, and a filtrate C is collected; the filtrate B is mixed with the filtrate C, such that a mixed liquid 2 is obtained; ethanol in the mixed liquid 2 is removed by evaporation, and a mixture is collected after evaporation; and the mixture is dissolved, such that a dye concentrate liquid is prepared. With the preparation method, the obtained lonicera edulis plant dye is safe and nontoxic, and has bright color and a special fruit scent.

Description

technical field [0001] The invention relates to a method for preparing vegetable dyes from indigo fruit, which belongs to the technical field of printing and dyeing. Background technique [0002] The raw materials of synthetic dyes commonly used in the printing and dyeing industry are aromatic hydrocarbon chemical products, so most of the synthetic dyes have varying degrees of impact and harm on the human body. These products can decompose more than 20 kinds of carcinogenic or allergic substances during the production process. The banned azo compounds can dissociate heavy metals such as lead (Pb), chromium (Cr), cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni) and mercury (Hg) under certain conditions ion. Even the synthetic dyes currently allowed to be used are not necessarily safe dyes, which more or less have certain effects and hazards on the human body, especially children's clothing and intimate textiles. At this stage, the so-called environmentally friendly synth...
