Q1: What types of substrates is Duasyn Acid Blue AE liquid pigment typically used for?
A: This pigment is primarily designed for dyeing and coloring acid dyeable substrates such as wool, nylon, silk, and polyamide-based fibers and textiles. It may also be applied in certain acid-compatible leather and paper systems where high tinctorial strength and level dyeing are required.
Q2: Is Duasyn Acid Blue AE liquid pigment suitable for food-contact or pharmaceutical applications?
A: No — this product is not certified for direct food contact, pharmaceutical use, or cosmetic applications. It is intended for industrial textile and specialty dyeing applications only. Regulatory compliance must be verified separately for each end-use scenario.
Q3: How should the liquid pigment be stored to maintain stability and performance?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and freezing conditions. Avoid prolonged exposure to elevated temperatures or humidity, which may affect viscosity and dispersion consistency over time.
Q4: Can Duasyn Acid Blue AE liquid pigment be mixed with other acid dyes or auxiliaries?
A: Yes — it is generally compatible with common acid dyes and standard dyeing auxiliaries (e.g., leveling agents, acetic acid, ammonium sulfate) under typical textile dyeing pH and temperature conditions. However, compatibility testing is recommended when formulating new combinations to ensure color reproducibility and stability.
Q5: What is the typical dosage range for achieving strong, uniform shades on nylon fabric?
A: Dosage depends on the desired shade depth and substrate characteristics, but typical usage ranges from 0.1% to 2% owf (on weight of fiber) for medium-to-dark blue tones on nylon. Lighter shades can often be achieved at lower concentrations, while deeper shades may require careful optimization with pH and temperature control.
