Embodiment 1

[0032] (1) Wash and dry the Avalokitesvara at first, and crush it to 70 meshes;

[0033] (2) Add the pulverized Avalokitesvara powder obtained in step (1) into a three-necked flask, and inject a mixed solvent of ethanol and water into the three-necked flask, and then place the three-necked flask in a water bath at 50°C Preheat and soak for 40min,

[0034] Wherein, in the mixed solvent of ethanol and water, the volume ratio of ethanol and water is 7:3,

[0035] The mass ratio of Avalokitesvara powder added to the three-necked flask to the mixed solvent of ethanol and water is 1:15;

[0036] (3) Put the three-neck flask preheated in step (2) into a microwave oven for enhanced microwave extraction, the microwave power is set to 600W, and the microwave extraction time is set to 120s to obtain the extract;

[0037] (4) Centrifuge the extract obtained in step (3) (4000r / min, 10min), and take the supernatant as the dye solution;

[0038] (5) Concentrating the dye solution obtained...

Embodiment 2

[0044] The Avalokitesvara extract prepared by the method in Example 1 is used as a vegetable dye to prepare digital printing ink, and the weight percentage and process of each component are as follows:

[0045]

[0046]

[0047] The rest is deionized water.

[0048] According to the weight percentage of each component in the above formula, each component is mixed, and the following preparation procedure is the same as that of Example 1.

Embodiment 3

[0050] The Avalokitesvara extract prepared by the method in Example 1 is used as a vegetable dye to prepare digital printing ink, and the weight percentage and process of each component are as follows:

[0051]

[0052] The rest is deionized water.

[0053] According to the weight percentage of each component in the above formula, each component is mixed, and the following preparation procedure is the same as that of Example 1.

Abstract

The invention belongs to the field of the development of natural vegetable dye, and particularly relates to a preparation method for extracting natural dye from gynura bicolor and an application. All components, namely, a gynura bicolor extract, a penetrant, an acrylic emulsion, a surfactant, diethylenetriamine, a bactericide and chitosan are added to deionized water in percentage by weight and evenly mixed at the normal temperature, a pH regulator is added to regulate the system to be alkaline, the solution is heated to the temperature of 60-70 DEG and continuously stirred for 1-3 h, the solution is cured for 2-5 h at the temperature and then cooled to the normal temperature, the solution is sequentially filtered by membranes with pore diameters of 0.55 mu m and 0.22 mu m, and a digital printing ink product is obtained finally. Pretreatment procedures such as sizing and the like are not required to be performed on a fabric before digital printing jet printing is performed on the fabric with the ink, jet printing procedures are reduced, and the dyed fabric is good in water vapor permeability and comfortable.

Description

technical field [0001] The invention belongs to the development field of natural plant dyes, and in particular relates to a preparation method and application of natural dyes extracted from Avalokitesvara. Background technique [0002] The so-called digital inkjet printing is to use scanners, digital cameras and other input means to input the pattern into the computer in digital form. After image software processing, the digital inkjet printing machine controlled by the computer directly sprays the printing ink to various Various input patterns are printed on the fiber fabric to obtain various printed fabrics. As one of the main consumables of digital inkjet printing, printing ink is also a key factor determining the success of inkjet printing technology. [0003] In the prior art, commonly used printing inks are generally small molecule dyes, which are mainly prepared from dyes, dispersion media, antibacterial agents, pH regulators, moisturizers, etc., and have a complete ...
