Reactive Orange FAQ
What is the recommended dyeing temperature for Reactive Orange?
The optimal dyeing temperature for Reactive Orange is 60-80°C (140-176°F). For best results, maintain this temperature range for 30-45 minutes during the dyeing process to ensure proper fixation. Lower temperatures may result in incomplete exhaustion, while higher temperatures can cause hydrolysis of the reactive group.
How does Reactive Orange perform in terms of color fastness?
Reactive Orange demonstrates excellent fastness properties: Wash fastness: 4-5 (ISO 105-C06), Light fastness: 5-6 (ISO 105-B02), Rubbing fastness: 4 (dry), 3-4 (wet). These ratings make it suitable for high-quality textile applications where color retention is critical.
Dyeing Parameters
| Parameter | Exhaust Dyeing | Pad-Batch |
|---|---|---|
| Dye Concentration | 0.1-5% owf | 10-50 g/L |
| Salt Concentration | 20-80 g/L | Not required |
| Soda Ash | 10-20 g/L | 15-30 g/L |
| Time | 30-60 minutes | 12-24 hours |
What is the shelf life of Reactive Orange and how should it be stored?
Reactive Orange has a shelf life of 24 months when stored properly in its original packaging. Store in a cool, dry place away from direct sunlight at temperatures below 30°C (86°F). Keep containers tightly closed when not in use to prevent moisture absorption, which can affect dye performance.
Application Guidelines
- Prepare dye bath with required amount of water
- Add dissolved salt and mix thoroughly
- Add pre-dissolved Reactive Orange dye solution
- Raise temperature to 40°C and run for 10 minutes
- Add alkali (soda ash) in portions
- Raise temperature to 60-80°C and maintain for 30-45 minutes
- Rinse thoroughly with cold water
- Soap at 95°C for 15 minutes (optional for better fastness)
- Final rinse and dry
