Reactive Red FAQ Section
Q: What fabrics work best with Reactive Red dye?
A: Reactive Red performs exceptionally well on cellulose fibers like cotton, linen, rayon and hemp. It bonds chemically with these fibers, resulting in superior color fastness. For synthetic fibers, we recommend using our specialized polyester dyes instead.
Q: How does Reactive Red compare to other red dyes in the market?
A: Reactive Red offers several advantages over conventional dyes: 1) Higher color yield requiring less dye per kg of fabric 2) Better environmental profile with lower COD/BOD levels in effluent 3) Excellent reproducibility batch-to-batch 4) Superior wash and light fastness properties meeting international standards.
Application Guidelines
For optimal results with Reactive Red, follow these application parameters:
- Salt Concentration: 50-80 g/L depending on depth of shade
- Soda Ash Concentration: 10-20 g/L
- Liquor Ratio: 1:10 to 1:20
- Dyeing Time: 30-60 minutes at fixation temperature
- Wash-off Procedure: Cold rinse → hot wash (80°C) → soap wash → final rinse
| Shade Depth (%) | Dye Quantity (g/kg fabric) | Salt (g/L) |
|---|---|---|
| 0.1-0.5 | 1-5 | 50 |
| 0.5-2.0 | 5-20 | 60 |
| 2.0-4.0 | 20-40 | 70 |
| 4.0+ | 40+ | 80 |
Additional Reactive Red FAQ
