Ambarsperse dyes are slowly sprinkled to ten / fifteen limes or us weigni in warm soft water at 40-50°c under slow stirring. The dye dispersion is than sieved and added to the dye bath. The container should always be properly re-sealed after the dye has been taken out.
Proper pre-treatment of the substrate is necessary before dyeing or printing. Otherwise, problems such as uneven dyeing, patchy dyeing, moire effect, dulling of shade, poor colour yield can be noticed.
Guideline Recipe
Set the dye bath at 60°C. add Ambarsperse dyes and raise the temperature to 130-135°C. Heating rate should be 1°C per minute, dye at 130-135°C for 20 - 60 minutes depending on the dye and depth of the shade. Cool the dye bath to 90°C and then drain, rinse and reduction clear.
| X% | AMBARSPERSE DISPERSE DYES |
| 0.5-1 g/l | DISPERSING AGENT |
| 0.5-1 g/l | LEVELING AGENT |
| 0.5 g/l | EDTA |
| Y g/l | ACETIC ACID FOR PH 4.5 - 5.5 |
Reduction Clearing Procedure
The material after dyeing is given reduction clearing treatment to remove loosely held unfixed dye particles. It also increases brilliancy and improves fastness properties.
| 2-3 g/l | Caustic Soda |
| 2 g/l | Sodium Hydrosulphite |
| 0.5 g/l | Leveling Agent |
Treat at 70°C (or 20 - 30 minutes. Then rinse and neutralise with acetic acid, soaping, followed by final rinsing.
