Key Industrial Applications
Textile Dyeing
Preferred for acrylic fibers with superior color yield (98-102% vs industry average 85-90%). Enables low-temperature dyeing at 85-90°C compared to conventional 100-110°C processes.
Biological Staining
Used in microscopy applications for bacterial cell wall visualization. Certified for use in Gram staining procedures per ISO 21530 standards.
Paper Coloring
Provides UV-resistant coloration for specialty packaging materials. Achieves 95% color retention after 500hrs QUV accelerated weathering testing.
Operational Best Practices
| Process Stage | Recommended Parameters |
|---|---|
| Dye Bath Preparation | 1-3% owf concentration, 40:1 liquor ratio |
| Fixation | Acetic acid (2-3g/L) at 70°C for 30min |
| Rinsing | 3-stage process: Warm (50°C) → Cold → Neutralization |
