Problems solved by technology

[0003] At present gallic plant antibacterial dyes are natural antibacterial agents, which have poor heat resistance and short antibacterial properties. Most of the textiles dyed and woven with gallic plant antibacterial dyes lose their antibacterial properties after being used for a period of time.

Embodiment 1

[0020] Embodiment 1: a kind of plant antibacterial dye derived from gallnut, comprising the following distribution ratio composition: 50 parts of gallnut raw material, 5-8 parts of chitin, 5-10 parts of benzophenone and 2-5 parts of dispersant.

[0021] A plant antibacterial dye derived from Galla japonica and an extraction method thereof, comprising the following steps:

[0022] S1: Clean and dry the gall raw material, and then place it in a traditional Chinese medicine pulverizer to pulverize it into powder;

[0023] S2: The powder is then placed in the extraction container, and 50 parts of ethanol and 70 parts of water are added, and mixed by mixing equipment, then heated to 50°C, and the gall dye is taken out and sent to the heat preservation device for heat preservation. The temperature is 50°C, then the filtered residue is put into the residue extruder for solid-liquid separation, the separated liquid is mixed with the original liquid, the mixing time of the mixing equip...

Abstract

The invention relates to the technical field of galla chinensis dyes, in particular to a galla chinensis-derived plant antibacterial dye and an extraction method thereof. The galla chinensis-derived plant antibacterial dye is prepared from the following components: 50 parts of a galla chinensis raw material, 5 to 8 parts of chitin, 5 to 10 parts of benzophenone and 2 to 5 parts of a dispersant. The galla chinensis raw material is cleaned and air-dried; and then the galla chinensis raw material is placed into a traditional Chinese medicine crusher so as to be crushed into powder. According to the galla chinensis-derived plant antibacterial dye and the extraction method thereof provided by the invention, the chitin and the benzophenone are added on the basis of the galla chinensis raw material; through the chitin, the antibacterial variety is enhanced, and the antibacterial range of the dye is expanded; through the benzophenone, the stability of the antibacterial agent is increased, and the antibacterial period is prolonged; the dispersing agent is added, so that the chitin and the benzophenone can be uniformly dispersed, meanwhile, sedimentation and condensation of particles can be prevented, and the antibacterial stability is further enhanced; and solid-liquid separation is carried out on residues through a crushing and extruding machine, so that raw materials are saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gallnut dyes, in particular to a plant antibacterial dye derived from gallnut and an extraction method thereof. Background technique [0002] Galla japonica is a unique aphid parasite gall on the salt skin wood. It is used in traditional Chinese medicine with the effect of moisturizing and inhibiting bacteria. After picking from the tree every summer, boil it in boiling water until it changes color and then dry it. Galla japonica is one of the main plants for dyeing black in ancient dyeing. It can be used to dye different shades of black and gray. When gall is dyed, you can get gray and black with almost no color cast, and the same is true for general primary color linen. Gallop dyed. [0003] At present, gall plant antibacterial dyes are natural antibacterial agents, which have poor heat resistance and short antibacterial properties. Most of the textiles dyed and woven with gall plant antibacterial dye...
