Is there any method to dye Turquoise Blue shades to dye at 60°C or less?

Yes you may dye Reactive Turquoise Blue G and H2GP combinations with VS or Bifunctional dyes at a lower temperature using the preconditioning method of dyeing.

In fact this method of dyeing yields unprectable higher depth and fastness proeperties. You will surly get at least 20% extra yield in dyeing depth.

Please see the table below for procedure and recipe: (Let us consider that the total combination % is more tha 4% o.w.f.)

Fabric (Knit/woven) or yarn preparation: (Unmercerised)

Process	Recipe	conditions	Remarks
Pretreatment: Demineralization:	Lufibrol MSD -0.5 g/l Kierlon JET B con - 0.5 g/l	For 20 minutes @ 50°C
Hot Wash		For 10 minutes @ 50°C
Scouring & Bleaching	Soda Ash = 3.0 g/l Stabilizer = 0.5 g/l Soap (Anionic) = 0.5 g/l Hydrogen Peroxide = 2.0 g/l	For 45 minutes @ 85°C
Hot Wash		For 10 minutes @ 50°C
Residual Peroxide Removal:	Peroxide Killer(enzyme) = 0.25 g/l Acetic Acid = 1.5 g/l	For 10 minutes @ 50°C	Check pH = 6
Cold Wash
Dye Bath Setup: First 1/2 Salt Addition	Resist Salt = 1 g/l Sod.Hexametaphosphate = 1 g/l Glauber's Salt = 40 grams/liter	For 10 minutes room temperature.
Second 1/2 Salt add.	Glauber's Salt = 40 grams/liter	For 10 minutes room temperature.
First 1/2 Soda add.	Soda Ash = 5 grams/liter	For 10 minutes room temperature.
Second 1/2 soda add	Soda Ash = 5 grams/liter	For 10 minutes room temperature.
First 1/4 caustic add	Caustic Soda = 1.5 grams/liter	For 10 minutes room temperature.
Second 1/4 caustic add	Caustic Soda = 1.5 grams/liter	For 10 minutes room temperature.
1st 1/2 dyestuff	Add 1/2 of total dissolved dye	Run for 10 minutes at room temperature	For dissolving use 1:15 LR @ 70°C
2nd 1/2 dyestuff	Add 1/2 of balance dissolved dyestuff.	Run for 10 minutes at room tempetature.
Temperaure setting		Raise temperature to 40°C if the combination contain any VS or Bifunctional dye else raise the temperature to 60°C . Run for 10 minutes
Third 1/4 caustic add	Caustic Soda = 1.5 grams/liter	Run 10 minutes at the above temp.
Fourth 1/4 caustic add	Caustic Soda = 1.5 grams/liter	Run 10 minutes at the above temp.
1st dyeing Time	Temperature 40°C	If your combination contain VS or Bifunctional dyestuffs, then continue dyeing for 30 minutes.	This is for allowing VS and Bifuntional dyes to get fixed to the fiber.
2nd dyeing time	Temperature 60°C	Continue dyeing for 60 to 90 minutes at this temperaue.
Drain - overflow cold wash
Neutralization	Acetic Acid = 1 g/l	at cold for 10 minutes
Hot Wash		at 75°C for 2 cycles
1st Soaping	Lissopol D paste or Dekol SN or Sandopur RSK liquid = 2 g/l	at 95°C for 20 minutes	Drain
2nd Soaping	Lissopol D paste or Dekol SN or Sandopur RSK liquid = 1 g/l	at 95°C for 20 minutes	Drain
Hot Wash		at 50°C for 10 minutes
Cold Wash		overflow
Final pH setup	Acetic Acid = 1 g/l	at cold for 10 minutes	drain and unload.
