Versatile Application MethodsBi Functional ME Series Reactive Dyes adapt easily to multiple textile processes, including exhaust, cold pad-batch, continuous, and semi-continuous dyeing. Their compatibility with both exhaust and pad dyeing methods allows manufacturers flexibility while achieving consistent shade and superior penetration for cellulosic fabrics.
Reliable Performance and FastnessThese dyes are engineered for high wash, light, perspiration, and rubbing fastness, preserving vibrant colors even under rigorous conditions. Their standardized strength and high solubility mean they deliver predictable, uniform results, reducing reprocessing and ensuring quality textiles every time.
Safe Storage and HandlingSupplied as odorless, solid powder or granules, Bi Functional ME Reactive Dyes should be stored in a cool, dry place away from direct sunlight. Under recommended conditions, their potency remains stable for up to two years. Custom packaging supports bulk supply, meeting the needs of dealers, exporters, and manufacturers.
FAQ's of Bi Functional ME Series Reactive Dyes:
Q: How are Bi Functional ME Series Reactive Dyes applied in textile processing?
A: These dyes are compatible with exhaust, cold pad-batch, continuous, and semi-continuous dyeing methods. Apply them to cellulosic fibers such as cotton, viscose, or linen, ensuring the use of required salt and alkali for effective fixation at recommended temperatures (60C - 80C).
Q: What benefits do bifunctional reactive groups offer to these dyes?
A: The presence of both vinylsulphone and monochlorotriazine groups enables strong chemical bonding with fibres, resulting in brighter shades, improved fixation, and excellent resistance to washing, light, and rubbing.
Q: When should salt and alkali be added during the dyeing process?
A: Salt and alkali should be introduced during the dyeing stage as they facilitate dye fixation onto the fiber. Proper timing and quantity optimize color yield and ensure high fastness properties.
Q: Where should Bi Functional ME Reactive Dyes be stored for maximum shelf life?
A: Keep the dyes in a cool, dry environment away from sunlight. When stored under these recommended conditions, the dyes maintain their performance and potency for up to two years.
Q: What makes these dyes suitable for industrial bulk use?
A: The dyes are stable, offered in large custom packaging (25 kg/50 kg), and standardized for consistent quality, making them ideal for bulk textile dyeing applications by dealers, exporters, and manufacturers.
Q: How does the solubility of these dyes affect the dyeing process?
A: Their complete solubility in water ensures uniform dispersion and penetration into fibers, resulting in even, vibrant coloring without patchiness or residue.
