Q1: What is the primary application field for Duasyn Acid Yellow XX-SF liquid pigment?
A: This liquid acid dye pigment is primarily formulated for use in acidic dyeing processes of polyamide (nylon) and wool fibers, especially in high-speed jet dyeing, beam dyeing, and exhaust dyeing systems where excellent levelness, reproducibility, and wet fastness are required.
Q2: Is Duasyn Acid Yellow XX-SF compatible with common auxiliaries used in acid dyeing baths?
A: Yes — it demonstrates good compatibility with standard acid dyeing auxiliaries such as leveling agents, acetic acid or sulfuric acid for pH control, and dispersing agents. However, compatibility should always be verified under actual process conditions, particularly when using cationic or strongly reactive additives.
Q3: How stable is the liquid formulation during storage and handling?
A: The liquid pigment exhibits good colloidal stability and shelf life when stored in its original sealed container at temperatures between 5 °C and 30 °C, protected from freezing and prolonged exposure to direct sunlight. Sedimentation is minimal under recommended storage conditions, and gentle agitation before use ensures uniform dispersion.
Q4: Can this pigment be used in combination with other Duasyn acid dyes for shade matching?
A: Yes — Duasyn Acid Yellow XX-SF is designed for compatibility within the broader Duasyn Acid dye range, enabling predictable and reproducible shade development when mixed with complementary acid dyes such as reds, blues, and blacks. Cross-compatibility testing is still recommended for critical applications.
Q5: What is the typical dosage range for achieving medium to deep shades on nylon?
A: Dosage depends on the desired shade depth, fiber type, and process conditions, but it is generally applied at low concentrations — typically ranging from 0.1% to 2% on weight of fiber (owf) for most commercial dyeing applications.
