Reactive Violet FAQ
Q: What makes Reactive Violet different from other violet dyes?
A: Reactive Violet stands out due to its superior chemical bonding with cellulose fibers, resulting in exceptional wash fastness and vibrant color retention. Unlike direct dyes that merely coat fibers, Reactive Violet forms covalent bonds that resist fading from washing, sunlight, and perspiration.
Q: How should I store Reactive Violet for maximum shelf life?
A: Store Reactive Violet in its original packaging in a cool, dry place away from direct sunlight. Maintain temperatures between 5-30°C with relative humidity below 65%. Properly stored, Reactive Violet maintains its potency for 24 months from production date.
Q: Can Reactive Violet be used for tie-dye or other special effects?
A: Absolutely. Reactive Violet is excellent for tie-dye, ombre, and shibori techniques. For tie-dye applications, premix the dye with urea solution (100g/L) to improve solubility, then apply to presoaked (in soda ash solution) fabric. The vibrant violet shades create stunning patterns with excellent definition.
