Leveling Agent for Dyeing

DESCRIPTION:

ARO - LAD is an effective leveling agent in dying of synthetics. It also works as dispersing Agent with increase in dye bath stability.

PROPERTIES:

• 
  
• Appearance : Yellowish Viscous Liquid - Slightly turbid.
• Chemical Character : Non-ionic Ethylene Oxide Condensate.
• Miscibility in Water : Good in all proportions in hot water.
• Solubility : Good to Dilute Acids / Dilute Alkalies / Hard Water & Salt Solution.
• Compatibility : Good with Anionic  Cationic or Non-ionic compounds.

APPLICATIONS:

• ARO -LAD liquid can be used in all operations for Polyester dyeing namely exhaust dyeing & high temperature beam dyeing as under:

• Exhaust Dyeing:-

Use of 0.5 to 1 gpl of ARO-LAD Liquid (2 to 4 gpl in Jigger dyeing) to the dye bath gives level dyeing. This is particularly suitable for light shades, textures polyester & where the liqur circulation is less effective.

ARO-LAD also works as a dispersing agent & addition of separate Dispersing Agent is not necessary.

In high temperature beam dyeing ARO-LAD Liquid : 0.5 to 1 gpl

Carrier - TCI : 1 to 2 gpl

Ammonium Sulphate : 2 gpl

Formic Acid 85% : as per requirement.

Dye bath is set at 85°c with above material. The liqur is circulated for 10 minutes, dyestuff dispersion added, temperature raised to 130°c in 45 minutes & dyeing continued at this temperature for 30-90 minutes, depending upon depth of the shade.
