Problems solved by technology

[0002] The traditional printing paste is composed of paint (dye) and printing paste. Since these two raw materials are currently made of chemical raw materials, they are polluting to a certain extent. Even if the pigment is extracted from natural plants on the market, it will Adding chemical substances cannot be pure natural and harmless, and the traditional printing paste is made of industrial starch or seaweed glue. To prevent starch fermentation from deteriorating, a certain amount of formaldehyde and other preservatives will be added to prevent the printing paste from deteriorating.

Embodiment 1

[0023] A method for coloring plant and edible starch mixed pigment printing, comprising the steps of:

[0024] 1) Extraction of pigment

[0025] Choose 200 grams of Pu’er tea, add 1 liter of water to boil, keep it warm at 95°C for 10 minutes to extract, filter it with gauze after cooling, and use the dyeing solution for later use;

[0026] 2) Preparation of slurry

[0027] Weigh 60 grams of edible starch, slowly add it to the 940ml dye solution prepared in step 1), stir, put it in a water bath and heat it to 95°C, replenish evaporated water in the middle, keep stirring for 1 hour, filter it with a nylon bag after cooling, Prepare printing paste;

[0028] 3) printing

[0029] The printing paste in step 2) is manually screen-printed, and overheated at 110° C. to ensure color fastness.

[0030] Pu'er tealeaves and starch mixed pigment printing in embodiment 1 are compared with traditional craft printing. (The comparison of the two printing methods is based on the premise tha...

Embodiment 2

[0037] A method for coloring plant and edible starch mixed pigment printing, comprising the steps of:

Abstract

The invention discloses a method for printing by using a colorable plant and edible starch mixed pigment, and belongs to the field of textile printing and dyeing. In the method, pure natural plant pigments replace the conventional chemical raw materials such as coatings (dyes) and the like, and edible starch replaces industrial starch to prepare a printing sizing agent, so zero pollution to environment and zero harm to human bodies are realized under the condition of keeping the effect of clothing design patterns.

Description

technical field [0001] The invention relates to a printing method, in particular to a printing method of coloring plants and edible starch mixed with pigments. Background technique [0002] The traditional printing paste is composed of paint (dye) and printing paste. Since these two raw materials are currently made of chemical raw materials, they are polluting to a certain extent. Even if the pigment is extracted from natural plants on the market, it will Adding chemical substances cannot be pure natural and harmless, and the traditional printing paste is made of industrial starch or seaweed glue. To prevent starch from deteriorating from fermentation, a certain amount of formaldehyde and other preservatives are added to prevent the printing paste from deteriorating. These substances that are harmful to the body and pollute the environment have brought a certain impact on our living environment, which is currently the biggest problem plaguing the textile printing and dyeing ...
