preparation example Construction

[0018] The preparation method of the tea tree stem ash is as follows: drying the tea tree stem of green tea until the water content is below 5%, and then fully burning the tea tree stem to obtain the tea tree stem ash.

[0019] The production method of the indigo of the present invention is as follows: after cutting the branches and leaves of the indigo, soak them in water for 5-7 days in a soaking tank, ferment the branches and leaves of the indigo, rub the stems and leaves of the indigo, rub the epidermis and leaves on the branches and put them into the soaking tank , pull out the remaining residue and wring it out, stir in the soaking tank for 10-15min, then filter the liquid in the soaking tank with gauze to obtain indigo liquid, stir and mix 100 parts by weight of indigo liquid with 3-5 parts by weight of tea tree stem ash for 10 After -15min, filter again with gauze, and the filtrate is left to settle to obtain indigo.

Embodiment 1

[0021] A kind of manufacture craft of indigo-dyed floral cloth, the steps are as follows:

[0022] (1) Preparation of staining solution:

[0023] According to the formula: 20% indigo, 16% sodium carbonate aqueous solution with a mass concentration of 35%, 5% quicklime, 7% rice wine, 6% fresh pig blood, 5% tea tree stem ash, and the rest of water. Mix all the components evenly to obtain the dyeing solution.

[0024] (2) Dyeing: Soak the pure cotton cloth in 20°C clear water for 5 minutes, then soak the pure cotton cloth in the dyeing solution for 4 minutes, take it out and oxidize it in the air for 4 minutes, repeat this process 5 times.

[0025] (3) Color fixation: After dyeing, wring out the pure cotton cloth and dry it in the shade without sunlight. After rinsing the pure cotton cloth in the shade solution for 3 times, dry it in the air. The components of the color-fixing solution are composed of 10% salt, 3% citric acid, 1% tea tree stem ash, and the balance of water.

Embodiment 2

[0027] A kind of manufacture craft of indigo-dyed floral cloth, the steps are as follows:

[0028] (1) Preparation of staining solution:

[0029] According to the formula: 25% indigo, 18% sodium carbonate aqueous solution with a mass concentration of 30%, 3% quicklime, 8% rice wine, 5% fresh pig blood, 6% tea tree stem ash, and the rest of water. Mix all the components evenly to obtain the dyeing solution.

[0030] (2) Dyeing: Soak the pure cotton cloth in 25°C clear water for 3 minutes, then soak the pure cotton cloth in the dyeing solution for 6 minutes, take it out and oxidize it in the air for 6 minutes, repeat this process 3 times.

[0031] (3) Color fixation: After dyeing, wring out the pure cotton cloth and dry it in the shade without sunlight. After rinsing the pure cotton cloth in the shade solution for 4 times, dry it in the air. The components of the color-fixing solution are composed of 15% salt, 5% citric acid, 2% tea tree stem ash, and the balance of water.

Abstract

The invention discloses a manufacturing process for an indigo dye and a blue-dyed printed fabric. The indigo dye is manufactured by the following components in percentage by weight: 20 to 25 percent of indigo, 16 to 18 percent of sodium carbonate aqueous solution, 3 to 5 percent of quick lime, 7 to 8 percent of rice wine, 5 to 6 percent of fresh pig blood, 5 to 6 percent of tea tree stem ash, and the balance of water. According to the manufacturing process, the ash which is manufactured by adopting tea tree stems which specifically exist in the Jiangnan area replaces the conventional ash manufactured by fern leaves or artemisia vulgaris, so that the colour fastness of a dyed fabric is high; the colour is bright; the process flow is short; the operation is convenient; the cost is low. The manufacturing process has the advantages that the dyed colour is bright; the colour fastness is high; the colour does not fade; the fabric can be washed together with white clothes; the process is simple; the cost is low; the operation is convenient; the dye can be reutilized; emission is avoided; the environment is not polluted. The manufacturing process has particularly outstanding effects when the manufacturing process is used in the conventional blue-dyeing technologies, such as tie-dyeing, wax-dyeing and clamp-dyeing.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a manufacturing process of indigo dye and indigo dyed cloth. Background technique [0002] In ancient times, people used to wear yiyi clothes. Since the invention of weaving, people began to wear cotton, linen and silk clothes. At first, everyone wore white clothes. In order to distinguish the noble from the humble by the color of the clothes, an emperor stipulated that the emperor should wear yellow robes, ministers should wear red robes, and ordinary people should wear blue shirts.
