SUBJ-3:
Studying all possible Fixation Modes of Reactive Printing. Evaluating CMC and Strength Report through Data Color
Chemicals:
Dye, Stock paste.
Purpose:
Purpose is to propose different fixation modes other than recommended (Steaming) with little or no compromise on yield and tone of shade.
Recipe:
Stock paste:
Mild. Oxidizing agent 10 g/Kg
Urea 100g/Kg
Sodium Bicarbonate 25 g/Kg
Alginate Thickener 25 g/Kg
Water Balance
Total 1 Kg
Dye Glass:
Dye 50 g/Kg
Stock paste Balance
Total 1 Kg
Options:
Options which are being tried are as follow.
Fixation through Curing/Heating only at strenter (Oven) without Air Flow Control.
Fixation through Curing/Heating only at strenter with Air Flow Control.
Fixation through Steaming by utilizing Saturated Steam.
In addition to these modes different other parameters like time was also varied to see the behavior of the dyes on varying fixation Modes.
Process:
Print and dry at 100-110°C.
Fixation:
Fixation Modes are
Oven 130C@15Min.
Strenter 160C@5Min.
Strenter 180C@5Min.
Strenter 200C@1Min.
Strenter 200C@5Min.
Saturated Steam 100C@1Min
Saturated Steam 100C@5Min
Saturated Steam 100C@15Min
Washing:
§ Cold rinse
§ Soap at 60oC With:
1-2 ml/l of Ladipur RSK liq.
§ Hot Rinse
§ Cold Rinse
