How to Beck Dye Cellulosics using Orcolitefast™ and Orcomine™ Dyes

- Prepare and pre-scour goods as necessary.
- Enter goods into dyebath set at 110°-115F(43-46°C) with:
  - X % Orcolitefast™ or Orcomine™ dyes on weight of goods(owg)
  - 1-10 g/L Gauber’s Salt dependent on depth of shade.
- Slowly raise temperature to 205°F(96°C) and run for one hour.
- Add 1-10 g/L Gauber’s Salt 20 minutes after reaching 205°F. Add more Glauber’s Salt after another 20 minutes for exhaustion of the dye as follows:
  - Light pastel shades 5-10 g/L
  - Medium shade 10-25 g/L
  - Heavy dark shades 25-40 g/L
- More salt additions might be necessary for darker shades. If levelness is a problem, the number of salt additions may be increased with the proportional decreased amount of salt.
- Cool back to 120°F(49°C).
- A cold “salt-rinse” might be necessary to help minimize dye wash-off/migration.
- Rinse cold until clear.
- After-fix if necessary using Orcofix F-NF™, or Orcofix DS™ depending on your requirements.
