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...
