Before the dyeing of Nomex^®, it is very important to make sure Nomex^® is pre-scoured well and evenly to remove any residual processing oils, waxes, and general soil.

For a standard pre-scour, enter goods into a bath at 100°F(38°C) and add 2% owg Orconol CHSA Conc™.  Raise temperature to 180°F(82°C) and run for 20 minutes. Cool to 120°F(49°C) and rinse well.

If goods are very soiled, a special scour using Orco Citrisolve DL-AAS-2™ may be necessary:

1. In a lukewarm bath add:

            1% owg Orconol CHSA Conc™

            5% owg Orco Citrisolve DL-AAS-2™

            1% owg Tetrasodium Pyrophosphate(TSPP)

2. Raise temperature to 160°F(71°C) and run for 20-30 minutes.
