Abstract

The invention discloses a preparation method of antimicrobial and preservative lonicera caerulea dye. The method comprises the following steps of firstly, putting lonicera caeruleas into water to be prepared into lonicera caerulea pulp; then, performing first filtering on the lonicera caerulea pulp, and collecting filter residues A and filter liquid A; putting the filter residues A into an extraction device, performing stirring after absolute ethyl alcohol is added, and performing second filtering after the stirring to collect filter liquid B; mixing the filter liquid A and the absolute ethyl alcohol; heating and stirring first mixed liquid obtained after the mixing; then, performing still standing for 8 to 24 hours; performing third filtering on the first mixed liquid to collect filter liquid C; mixing the filter liquid B and the filter liquid C to prepare second mixed liquid; performing evaporation to remove ethyl alcohol in the second mixed liquid; collecting an evaporated mixture; dissolving the mixture to be prepared into dye concentrated liquid; finally, adding origanum oil into the dye concentrated liquid. The lonicera caerulea plant dye prepared by the method has the advantages that the concentrated liquid is amaranthine; the color and the luster are vivid; safety and no toxicity are realized; preservative and antimicrobial effects are achieved; the use and the storage are convenient.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and antiseptic indigo dye, 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 fri...
