Embodiment 1

[0023] Put Longjing tea leaves and water into a stainless steel pot and boil for 30 minutes according to the weight ratio of tea leaves and water being 1:40, and then filter to obtain tea dyeing liquor. Then the soil cloth is put into the soybean milk with a mass concentration of 5% and soaked for 30 minutes for pretreatment. Put the pretreated earthen cloth into the tea dyeing solution with a bath ratio of 1:10 and boil for 30 minutes for the first tea dyeing, stirring continuously during the boiling process. At the same time, the coal dyeing solution was prepared according to the weight ratio of alum and water of 1:100. Put the homemade cloth after the first tea dyeing into the coal dyeing solution at a bath ratio of 1:10 for coal dyeing for 20 minutes, and the coal dyeing temperature is 70°C. Take out the coal-dyed earthen cloth and wring it dry, then put it into the tea dyeing solution, the bath ratio is 1:10, then add salt according to the mass ratio of salt to tea dyein...

Embodiment 2

[0025] Put Longjing tea leaves and water into a stainless steel pot and boil for 35 minutes according to the weight ratio of tea leaves and water being 1:45, and then filter to obtain tea dyeing liquor. Then the soil cloth is put into the soybean milk with a mass concentration of 5% and soaked for 35 minutes for pretreatment. Put the pretreated earthen cloth into the tea dyeing solution with a bath ratio of 1:15 and boil for 35 minutes for the first tea dyeing, stirring continuously during the boiling process. At the same time, the coal dyeing solution was prepared according to the weight ratio of alum and water of 1:150. Put the homemade cloth after the first tea dyeing into the coal dyeing solution at a bath ratio of 1:15 for coal dyeing for 25 minutes, and the coal dyeing temperature is 75°C. Take out the coal-dyed earthen cloth and wring it dry, then put it into the tea dyeing solution, the bath ratio is 1:15, then add salt according to the mass ratio of salt to tea dyein...

Embodiment 3

[0027] Put Longjing tea leaves and water into a stainless steel pot and boil for 30 minutes according to the weight ratio of tea leaves and water being 1:40, and then filter to obtain tea dyeing liquor. Then the soil cloth is put into the soybean milk whose mass concentration is 8% and soaked for 30 minutes for pretreatment. Put the pretreated earthen cloth into the tea dyeing solution with a bath ratio of 1:10 and boil for 30 minutes for the first tea dyeing, stirring continuously during the boiling process. At the same time, the coal dyeing solution was prepared according to the weight ratio of alum and water of 1:150. Put the homemade cloth after the first tea dyeing into the coal dyeing solution at a bath ratio of 1:10 for coal dyeing for 20 minutes, and the coal dyeing temperature is 80°C. Take out the coal-dyed earthen cloth and wring it dry, then put it into the tea dyeing solution, the bath ratio is 1:10, then add salt according to the mass ratio of salt to tea dyeing...

Abstract

The invention provides a tea dyeing method of native cloth. The tea dyeing method of native cloth comprises the following steps: 1. preparing tea dyeing liquid, namely, boiling tea leaves and water in a pot for 30-40min, and filtering to obtain the tea dyeing liquid; 2. performing pretreatment, namely, soaking native cloth into soybean milk for 30-40min; 3. performing tea dyeing for the first time; 4. preparing mordanting liquid, namely, preparing mordanting liquid from white alum and water; 5. performing mordanting, namely, placing the native cloth subjected to tea dyeing for the first time into the mordanting liquid for mordanting; 6. carrying out tea dyeing for the second time, namely taking out the mordanted native cloth, squeezing out water, placing into the tea dyeing liquid, adding table salt and boiling for 30-40min; and 7. rinsing and drying in air. According to the tea dyeing method of native cloth, the native cloth is pretreated by soybean milk before being dyed, so that protein is attached to the native cloth and the native cloth is easy to color, white alum water is used as a mordanting agent for fixing color of the native cloth subjected to tea drying for the first time, table salt is added during tea dyeing for the second time for further color fixation, and the final native cloth subjected to tea dyeing has a good coloring effect and high color fastness.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing, in particular to a tea dyeing method for earthen cloth. Background technique [0002] At present, most of the dyeing of clothing fabrics uses chemical dyes, and chemical dyes need to use toxic solvents such as formaldehyde in the dyeing process, and there may be residual formaldehyde in the dyed clothing fabrics, which is not good for human health. Vegetable dyes are gradually recognized by people because of their environmental protection and health. Tea dyeing is a kind of plant dyeing process. Tea dyed textiles have a faint tea fragrance, are natural and harmless, and have good antibacterial properties. Tea dyed products are more and more popular among people. However, the current tea dyeing process is not mature enough, and the coloring effect of tea-dyed clothing or cloth is not good, the color fastness is low, and it is easy to fade. Contents of the invention [0003] The object of ...
