Application Guide
Disperse Brilliant Green is typically used in high-temperature dyeing processes (120-130°C) for polyester fabrics. The recommended dye concentration is 0.5-3% of the fabric weight, depending on the desired shade depth. For best results:
- Prepare dye bath with dispersing agent (1-2 g/L)
- Adjust pH to 4.5-5.5 using acetic acid
- Heat gradually to 130°C over 30-40 minutes
- Maintain temperature for 30-60 minutes
- Cool and rinse thoroughly
FAQs About Disperse Brilliant Green
Q: What fabrics can Disperse Brilliant Green dye?
A: Disperse Brilliant Green is primarily used for dyeing polyester fibers, including PET, PTT, and other synthetic fabrics. It can also be used for dyeing acetate and nylon, though the color fastness may vary.
Q: How to improve the color yield of Disperse Brilliant Green?
A: To enhance color yield, ensure proper dye bath preparation with sufficient dispersing agent (1-2 g/L), maintain precise temperature control during dyeing, and use appropriate auxiliaries like leveling agents. Post-dyeing reduction clearing can also improve color brightness.
Q: Is Disperse Brilliant Green safe for textile workers?
A: When handled properly with standard protective equipment (gloves, masks, and goggles), Disperse Brilliant Green is safe for industrial use. However, avoid inhalation of dye powder and ensure adequate ventilation in working areas.
