[0038] figure 1 For the flow chart of the indigo dye preparation method that the first embodiment of the present invention provides, please refer to figure 1 .

[0039] The present embodiment provides a kind of indigo dye preparation method, and described indigo dye preparation method comprises the following steps:

[0040] S11: To generate blue juice slurry, soak the indigo grass in water, add cowhide tree bark and lime to decompose indigo, then remove the residue, and the remaining aqueous solution is the blue juice slurry.

[0041] In the step of generating the blue juice slurry, the weight relationship of each component is: 50 parts of indigo, 2.5 parts of cowhide bark, 1.5 parts of lime, and 75 parts of water. Preferably, the time for soaking the indigo grass in water is 10 to 25 days.

[0042] S12: To strengthen the decomposition of indigo, add lime to the blue juice slurry, and beat until foaming, to strengthen the decomposition of indigo.

Abstract

The invention provides a method for preparing indigo dye and a cloth dyeing method, and relates to the technical field of cloth dyeing. The preparation method of the blue indigo dye comprises the following steps: generating blue juice slurry, soaking the blue indigo grass in water, adding cowhide tree bark and lime to decompose the indigo, then removing the residue, and the remaining aqueous solution is the blue juice slurry; Decompose indigo, add lime to the blue juice slurry, and beat until foaming, strengthen the decomposition of indigo; generate blue glue, let the blue juice slurry stand still, make the indigo decompose and sink through the lime, and become gelatinous, and the upper layer Filter out the clear water, and the remaining jelly is blue gum; to produce indigo dye, dilute the blue gum with water, add wormwood ash water and wine and stir evenly to get indigo dye. The preparation method of the indigo dye has simple operation and low cost, and the produced indigo dye has strong adhesion and bright color.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing, in particular to a method for preparing indigo dye and a method for dyeing cloth. Background technique [0002] Indigo is a plant of the family Acanthaceae, also known as: Daye Donglan, Qinglan, Banlan, and Shanlan. Its branches and leaves can be processed into dyes, and can be used for medicine. Epistaxis, chest pain, hemoptysis, mumps and other symptoms. [0003] In many parts of China, especially in minority areas, there is a tradition of using indigo dyes to dye cloth and sew clothes. The Miao people in Yunnan, in particular, are typical representatives of indigo-dyed cloth for sewing clothes. People use indigo grass to make indigo dye and use it as raw material for dyeing cloth. After boiling, they put it into a dyeing vat, and then dry the dyed cloth and hammer it with a wooden stick to become a self-made bright cloth. Clothes made of the fabric have good warmth retention and wear-re...
