Abstract

The invention belongs to the field of dyes, and specifically relates to a method for preparing perspiration-resistant and chlorine-resistant indigo dye water by utilizing an indigo paste. The method comprises the following specific steps: S1, adding water into the indigo paste to obtain a water solution of the indigo paste; S2, adding fatty alcohol-polyoxyethylene ether, polyoxyethylene benzene alkyl phenolic ether, nekal and a flourescent brightener VBL into water in sequence, and stirring uniformly; S3, adding the water solution of the indigo paste into the solution obtained in the step S2, then adding sodium hydrogen sulfate, sodium chloride and vinasse, and stirring uniformly; and S4, putting the solution obtained in the step S3 into a dyeing pool, sealing, standing for fermentation until the solution is light yellow, using a whiteware container for sampling vibration observation, and stopping fermentation when a light blue flowing cloud appears in the solution. The indigo dye water prepared in the invention is high in perspiration-resistant color fastness and chlorine-resistant color fastness; and meanwhile, the indigo dye water prepared with the method is high in sunshine-resistant color fastness, washing-resistant color fastness and rub-resistant color fastness, and is also high in dye-uptake.

Description

technical field [0001] The invention belongs to the field of dyes, and in particular relates to a method for preparing perspiration-resistant and chlorine-resistant indigo dyeing water with indigo paste. Background technique [0002] Indigo is the powder or agglomerate obtained by processing the leaves of the Acanthaceae plant Malan, and the leaves of the Cruciferous plants Isatis indigo, Grass Daqing, and the leguminous plant Indigo can also be produced. [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 pr...
