How to Scour Polyester/Nylon Blends
Polyester/Nylon may require scouring before dyeing or bleaching to remove any residual processing oils, waxes, or general soil. The scouring procedure would be similar to that of 100% nylon.
One common procedure is to scour goods for 30-45 minutes in a bath at 180°F(82°C) containing:
- 1-1.5% owg Orconol CHSA Conc™
- .07-0.1 oz/gal(0.5-.75 g/L) Tetrasodium Pyrophosphate(TSPP)
Drop Bath and rinse goods well.
Another procedure is to run goods for 30 minutes in a bath at 180°F(82°C) containing 1-2% owg Anionic Wetting Agent.
After scouring, drop bath and rinse well.
