While dyeing self-Shade of Shade based on Turquoise, e.g. T Blue H2GP Glauber Salt must be used as a Electrolyte (Salt) for the Dyeing Process. T Blue H2GP and Shade based on T Blue H2GP must be dyed by grafting dyeing method Grafting dyeing Method. : After alkali addition, dye for 60 minutes at 60°C. Raise the temperature to 80°C. and Continue for 40 minutes. •   For Dyeing 3-4% Shade and above an after treatment with Non formaldehyde dye fixing agent (Camafix NFD) is recommended.   Padding with CAMEX ME Reactive Dyes   Padding Recipe:   Camex ME - 10-70 g/l Urea - 50-100 g/l Resist Salt - 10 g/l (Alkali) Soda ash - As per table Wetting agent - 1 - 3 g/l Back to Top Alkali requirement   Dyestuff g/l - Soda ash g/l 0-15 - 6 15-30 - 9 Above 30 - 12   Process : The fabric is first padded at room temperature with 70 - 80 % expression and dried. The dried material in than steamed in a continuous steamer for 7 - 10 minutes at 100 - 105°C and then washed and dried. Before steaming the fabric must be completely dry otherwise patches or unevenness may be observed.   Printing with CAMEX ME Reactive Dyes   Steaming Method   Printing paste recipe   X Parts CAMEX ME Dyestuff is mixed with 20-50 Parts Urea 200 Parts Water 500 Parts Thickening (3% Sodium Alginate) 20 Parts Sodium bi-carbonate 10 Parts Resist Salt Y Parts Water or Thickening (as per required viscosity) And bulk to 1000 Parts     Print -'Dry - Steam at 105°C for 12-15 minutes - Hot and cold Wash - Soap at boil for 15-20 min followed by rinse hot & cold Wash.

For Very heavy depth shades soaping required twice. 10 Rinse Warm   Rinse Cold until clear solution is obtained.   For Medium to heavy shades an after treatment with 1 - 2 g/l dye fixing agent is given at room temperature (40°C at acidic pH of 5 - 5.5 to improve fastness properties.)       G.
