Disperse Violet FAQ
Q: What is the recommended dyeing temperature for Disperse Violet?
A: The optimal dyeing temperature for Disperse Violet is between 120-130°C (248-266°F) for polyester fibers. For nylon, the temperature range is typically 90-100°C (194-212°F). It's important to maintain precise temperature control during the dyeing process to achieve consistent color results.
Q: How should Disperse Violet be stored?
A: Disperse Violet should be stored in a cool, dry place away from direct sunlight and moisture. The storage temperature should be maintained between 5-30°C (41-86°F).
