on the original blank and carry out bleaching and dyeing treatment the proportion of bleaching agent adopted during bleaching is 27 vt hydrogen peroxide 6 g l naoh 2 g l refining agent 1 5 g l hydrogen peroxide stabilizer 1 g l chelating agent 1 g l treat at 98 u00b0 c for 55 min then carry out polishing treatment and finally carry out dyeing then carry out dyeing treatment on towels after processing the adopted process is a conventional process during dyeing the specific dosages of the adopted dyeing agents are as below reactive dyes dystar rgb red 0 001 10 dystar rgb yellow 0 001 10 and dystar rgb blue 0 001 10 for the adopted process it can also refer to the following method inject the reactive dye at room temperature 10 min u2192 circulate for 10 min u2192 add anhydrous sodium sulfate 10 min u2192 circulate for 10 min u2192 add sodium carbonate 10 min u2192 temperature rises to 60 degrees 2 degrees min u2192 color fixing time is determined by color depth u2192 wash in water for 5 min u2192 carry out thermal washing for 15 min u2192 carry out soaping for 15 min depend on color depth u2192 wash in water u2192 soften in addition to this it can adopt other conventional processes and reactive dye formulas in the above process the adopted desizing agent is aqueous solution.
