Embodiment 1

[0019] A kind of indigo dyeing method, comprises the following steps:

[0020] (1) Preparation of dyeing solution: Soak Radix isatidis leaves in water for 3 days, the weight ratio of Radix isatidis leaves to water is 5:7, then add lime water for purification treatment for 1 day, remove the residue, and separate the water from the sediment to obtain The sediment is blue indigo mud. Put the blue indigo mud into the dye vat, and add water, white wine and soil alkali to the dye vat. The weight ratio of blue indigo mud, water, white wine and soil alkali is 1500:20:800:800, soak at room temperature After 3 days, the staining solution was obtained;

[0021] (2) Dyeing and color fixation: Stir the dyeing solution until the bubbles produced by the agitation do not break for 5 minutes and the color is dark blue, the dyeing solution is active. Put the fabric in the dyeing solution for 1 hour and then take out the hanging dripping water, every 10 square meters Use 2600g dyeing liquid for...

[0027] A kind of indigo dyeing method, comprises the following steps:

[0028] (1) Preparation of dyeing solution: Soak Radix isatidis leaves in water for 5 days, the weight ratio of Radix isatidis leaves to water is 5:8, then add lime water for purification treatment for 3 days, remove the residue, and separate the water from the sediment to obtain The sediment is blue indigo mud. Put the blue indigo mud into the dye vat, and add water, white wine and soil alkali to the dye vat. The weight ratio of blue indigo mud, water, white wine and soil alkali is 1500:30):1200:1200, at room temperature Soak for 5 days to get the dyeing solution;

[0029] (2) Dyeing and color fixation: Stir the dyeing solution until the bubbles produced by the agitation do not break for 10 minutes and its color is dark blue, the dyeing solution is active. Put the fabric into the dyeing solution and soak it for 5 hours, then take out the hanging dripping water, every 10 square meters Use 4000g of dyeing s...

Embodiment 3

[0035] A kind of indigo dyeing method, comprises the following steps:

[0036] (1) Preparation of dyeing solution: Soak Radix isatidis leaves in water for 4 days, the weight ratio of Radix isatidis leaves to water is 5:7.5, then add lime water for purification treatment for 2 days, remove the residue, and separate the water from the sediment to obtain The sediment is blue indigo mud. Put the blue indigo mud into the dye vat, and add water, white wine and soil alkali to the dye vat. The weight ratio of blue indigo mud, water, white wine and soil alkali is 1500:25:1000:1000, soak at room temperature After 4 days, the staining solution was obtained;

[0037] (2) Dyeing and color fixation: Stir the dyeing solution until the bubbles produced by the agitation do not break for 8 minutes and its color is dark blue, the dyeing solution is active. Put the fabric into the dyeing solution for 3 hours and then take out the hanging dripping water, every 10 square meters Use 3200g of dyeing...

Abstract

The invention belongs to the technical field of textiles, and in particular relates to an indigo cloth dyeing method. The indigo cloth dyeing method comprises the following steps: after immersing isatis roots and leaves for a period of time, adding lime water and carrying out purification treatment; fishing out residues, and separating water and sediment; adding water, Baijiu and soil alkali; immersing at room temperature for a period of time to obtain a dyeing solution; activating the dyeing solution; after putting cloth into the dyeing solution and immersing for a period of time; then taking out the cloth and suspending to drop water; repeating for 3 to 5 times every day; after continually dyeing for 3 to 5 days, washing the dyed cloth and airing; spraying the cloth to be wet by utilizing the Baijiu and steaming by utilizing boiled water, so as to prepare a product. The cloth dyed by the indigo cloth dyeing method has better color fastness and more bright color; a technological process is short, and the operation is convenient; the cost is lower, and the product does not fade.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for dyeing cloth with indigo. Background technique [0002] Natural dyes are traditional dyes that have been developed and used by humans since ancient times. It has a long history of use and is closely related to the development of human culture. It is a traditional material with distinctive national and regional characteristics. It includes mineral dyes , animal dyes and vegetable dyes, among which vegetable dyes have the most types and the widest range of applications, so natural dyeing is often simplified as plant dyeing. Dyeing cloth with plant pigments is called plant dyeing. Generally, plant dyeing refers to the process of using heat to cook plant pigments as a dye solution. Different plants will have different colors. [0003] In many places in our country, especially the places where ethnic minorities live together, the dyes made of indigo are used to dye clot...
