Problems solved by technology

[0005] Chinese invention patent CN101775234A discloses a method for extracting natural dyes from gorgon husks and its application in pure cotton dyeing, but this method needs to use a large amount of ethanol in the preparation process, and ethanol is a very volatile organic compound. The loss is very large, so the cost of this method is high, the process is long, and needs to be improved

Embodiment 1

[0020] Embodiment 1: a kind of extraction method of Gorgon husk natural dye is carried out according to the following steps:

[0021] Step 1: pretreatment of raw materials, rinse the gorgon shell with clean water, crush it repeatedly with a pulverizer, pass through a 250-mesh sieve, and take the under-sieve;

[0022] Step 2: Add a small amount of dispersant and lubricating oil to the crushed gorgon shell powder, and enter it into a 4000rpm high-speed ball mill to obtain an ultra-fine gorgon shell powder dispersion;

[0023] Step 3: Concentrate the superfine gorgon shell powder dispersion by vacuum distillation, and dry at low temperature to obtain the natural dye of gorgon shell.

[0024] Described dispersant is ethylene glycol.

[0025] Described lubricating oil is lard.

Embodiment 2

[0027] A method for extracting natural dyes from gorgon husks, carried out according to the following steps:

[0028] Step 1: pretreatment of raw materials, rinse the gorgon shell with clean water, crush it repeatedly with a pulverizer, pass through a 250-mesh sieve, and take the under-sieve;

[0029] Step 2: Add a small amount of dispersant and lubricating oil to the crushed gorgon shell powder, and enter it into a high-speed ball mill to obtain an ultra-fine gorgon shell powder dispersion;

[0030] Step 3: concentrating the superfine gorgon shell powder dispersion by vacuum distillation to obtain the natural dye extract of gorgon shell.

[0031] Described dispersant is ethylene glycol.

[0032] Described lubricating oil is lard.

Embodiment 3

[0034] A method for extracting natural dyes from gorgon husks, carried out according to the following steps:

[0035] Step 1: pretreatment of raw materials, rinse the gorgon shell with clean water, crush it repeatedly with a pulverizer, pass through a 250-mesh sieve, and take the under-sieve;

[0036] Step 2: Add a small amount of dispersant and lubricating oil to the crushed gorgon shell powder, and enter it into a 5000rpm high-speed ball mill to obtain an ultra-fine gorgon shell powder dispersion;

[0037] Step 3: Concentrate the superfine gorgon shell powder dispersion by vacuum distillation, and dry at low temperature to obtain the natural dye of gorgon shell.

[0038] Described dispersant is ethylene glycol.

[0039] Described lubricating oil is lard.

Abstract

The invention relates to a purification method of euryale ferox shell natural dye. According to the method, natural dye components in euryale ferox shells can be effectively extracted, the extracted natural dye components not only have good dyeing property, but also have a drug healthcare function which is not possessed by other synthetic dye, and better drug healthcare function can be obtained through a suitable purification method.

Description

technical field [0001] The invention relates to the technical field of textile dyes, in particular to a method for purifying natural dyes from gorgon husks. Background technique [0002] In human history, natural fuels have made indelible contributions to beautifying people's lives. Since the end of the 19th century, due to the rapid development of synthetic dyes, natural fuels have basically withdrawn from the field of fabric dyeing. With the increasing awareness of human environmental protection and the increasing concern for their own health, the harm of some synthetic dyes to human health and the ecological environment has become more and more noticeable. With the improvement of modern technology level, especially the improvement of modern manufacturing level, people have higher and higher requirements for the safety and health care of the clothing industry, and natural dyes have begun to be valued by people again. Animal and vegetable dyes in natural dyes are extracte...
