High lightfastness and washfastness on polyamide substrates, meeting stringent textile performance requirements.
Excellent levelness and reproducibility in both batch and continuous dyeing processes.
Good compatibility with common anionic auxiliaries and pH-stable across typical acid dyeing ranges (pH 4.5–6.0).
Low metal migration risk due to stable palladium-based metal complex structure.
Optimized for high-yield dyeing with minimal unfixed dye, reducing wastewater load and improving effluent quality.
Dyeing of nylon 6 and nylon 6,6 apparel fabrics (e.g., sportswear, hosiery, and intimate apparel).
Coloration of technical textiles including automotive seat covers and airbag fabrics.
Batch dyeing of nylon carpet yarns requiring deep navy shades with high fastness.
Exhaust dyeing of nylon-based engineered fibers used in filtration and industrial belts.
