Embodiment Construction

[0024] Example:

[0025] Take 13800kg of clean water and heat it in groups to 90°C-100°C, add plant ash with 30% of the clean water mass, precipitate after stirring, and filter out the dregs; when the soft water is cooled to about 25°C, add 200kg of indigo paste and 150kg of rice wine with a mass fraction of 35%, Stir evenly to prepare an aqueous solution of blue indigo paste; add the prepared blue indigo paste solution into the thermal insulation dyeing pool, cover with a plastic film to seal, and let it stand for fermentation for 10 days; after 72 hours, it is regularly unpacked every day to observe the fermentation of the dyed water and make a good preparation Record. If the solution is blue-brown, it needs to continue to ferment; if the solution is light yellow, you can take a sample and shake it in a white pottery container for observation, and there will be light blue flowing "clouds" in the solution, indicating that the dyed water is fully fermented and active, and beco...

Abstract

The invention discloses a method for preparing high dye-uptake anti-decolorization indigo dyeing water from indigo paste, comprising steps of: (1) soft water preparation: taking and heating clear water until the temperature of the water closes the boiling point, adding plant ash, depositing after stirring, filtering off dregs and to obtain soft water; (2) solution preparation: adding indigo paste and rice wine after the soft water cools, stirring well and to obtain an indigo paste aqueous solution; (3) sealed fermentation: adding the indigo paste aqueous solution into a thermal insulation dyeing pool, sealing by capping a plastic foil, still standing to fermentation for a fermentation time determined by season and the temperature of the dyeing pool; (4) observation: after 72 hours of fermentation, sealing off, observing, and recoding the status of fermentation every day at regular time; and taking samples by a white pottery and observing with shaking after the solution becomes light yellow, dyeing water with dyeing activity being the solution presenting light blue flowing "cloud"; (5) preservation and standby application: canning the dyeing water and placing the dyeing water in a shade place for preservation and standby application. The method solves the problem of activity of indigo paste, provides dyes for batik, and lays down a foundation for developing batik products.

Description

technical field [0001] The present invention relates to dyes, specifically, to the raw materials of dyes, and further to indigo dyes. technical background [0002] Indigo is a plant of the acanthaceae Ma blue ( Baphicacanthus cusia Brem ) powder or agglomerates obtained by processing the leaves, and the leaves of cruciferous plants Isatis indica, Grass Daqing, and leguminous plants indigo can also be obtained from blue indigo. [0003] Historically, the dyeing technology of natural plant dyes has spread throughout the East, and the tradition of using plant dyeing is still preserved in many villages and ethnic minority areas in my country. Among them, the plant dye indigo is a special plant vat dyeing material used in Chinese blue calico. Collecting bluegrass to make indigo has long been recorded in ancient Chinese books. However, indigo dye also has its own defects: one is that the processing and production of the dye is cumbersome, and many processes are required from co...
