| titleOfInvention | Indigo dyeing method and manufacturing method of indigo dyeing product |
| abstract | Provided is an indigo dyeing method capable of obtaining a desired dyeing density, hue or color using natural indigo or synthetic indigo and simple procedures. (1) A procedure for dissolving a dye containing natural indigo, hydrosulfite and caustic soda in hot water to prepare a concentrated dyeing solution having a redox potential of -1,000 to -800 mV and a pH of 13.0 to 14.5, (2) A procedure for preparing a diluted staining solution containing the concentrated staining solution, hydrosulfite and caustic soda and having an oxidation-reduction potential of −700 to −600 mV and a pH of 10.5 to 11.5, (3) an object to be dyed in the diluted staining solution (4) a procedure for supplying water until the oxidation-reduction potential becomes −550 to −450 mV, (5) after the procedure (4), the acid and There is provided an indigo dyeing method comprising a step of immersing an object to be dyed in a treatment liquid containing hydrogen peroxide, and (6) a step of immersing the object to be dyed in a treatment liquid containing a soaping agent after the procedure (5). |
