How to Atmospherically Dye Polyester Using Orcocilacron™ Dyes

Atmospheric dyeing of polyester calls for low-to-medium energy Orcocilacron disperse dyes with the addition of a carrier to further swell the fiber allowing increased penetration of the dye into the polyester fiber.

  • Prepare and pre-scour polyester.
  • Enter goods in bath at 120°F(49°C) containing:
  • Circulate for 10 minutes and add
  • Raise temperature to 205°F(96°C) and run for 50-120 minutes for maximum penetration.
  • Cool back to 180°F(82°C) and rinse well at this temperature.
  • Cool back to 120°F(49°C) while rinsing.
  • After-scour(after-clear) with:
      • 2 – 4% owg Reducing Agent such as Sodium Hydrosulphite
        at a temperature of 140°F(60°C) and run for 15 -20 minutes.
      • Drop bath and rinse well.
