Procedures
Exhaust
- Pre-disperse Orco Sunguard N-2™ in warm water. Use 1.0-2.5% Orco Sunguard N-2™ on weight of fabric (owf)depending on dye & lightfastness requirements and on the amount of nylon present.
- In a bath at 75-90°F(24-32°C) add one of the following buffering systems:
- pH < 6 Ammonium Acetate and acetic acid
- pH 6-8 MSP and DSP
- pH >8 TSPP and acetic acid
- Add X% Orco Sunguard N-2™
- Circulate for 5 minutes and add dyes.
- Raise to 212°F(100°C) over one hour to promote levelness.
- Run for one hour and cool to 140°F(60°C).
- Rinse, extract, and dry.
After-treatment
- Set fresh bath to 75-90°F(24-32°C) and add 1-2% owf Orco Sunguard N-2™.
- Raise temperature to 160-180°F(71-82°C) over one hour. Hold for 20 minutes at this temperature.
- Rinse, extract, and dry.
