Vat Blue FAQ
What is the recommended storage condition for Vat Blue?
Vat Blue should be stored in a cool, dry place away from direct sunlight. Keep containers tightly closed when not in use. The ideal storage temperature is between 5°C and 30°C. Under proper storage conditions, Vat Blue maintains its quality for at least 24 months from the date of manufacture.
How does Vat Blue compare to other vat dyes in terms of environmental impact?
Vat Blue is formulated with environmental considerations in mind. It contains no heavy metals or restricted amines, and our production process follows strict environmental protection standards. The dye has excellent exhaustion rates (typically 90-95%), minimizing waste water contamination. Furthermore, Vat Blue achieves high fastness properties, reducing the need for after-treatments that might generate additional waste.
Can Vat Blue be used for continuous dyeing processes?
Yes, Vat Blue is suitable for both batch and continuous dyeing processes. For continuous dyeing, we recommend using the pad-steam method with proper reduction conditions. The typical padding liquor contains 10-50 g/L of Vat Blue (depending on shade depth), along with the appropriate amount of reducing agent and alkali. Steaming should be done at 102-105°C for 45-60 seconds to ensure complete penetration and fixation.
