Highly efficient blue-white fluorescence for superior brightness enhancement in polyester and polyester/cotton blends.
Excellent thermal stability suitable for high-temperature dyeing and thermofixation processes up to 200 °C.
Good solubility in common organic solvents and compatibility with standard disperse dye formulations.
Low volatility and minimal sublimation loss during heat treatment, ensuring consistent whiteness retention.
Reproducible performance with low batch-to-batch variation, supporting stringent quality control in industrial production.
Whitening of polyester fibers and fabrics in continuous dyeing and thermofixation systems.
Brightening of polyester/cotton blended textiles during high-temperature exhaust or pad-dry-cure processes.
Enhancement of whiteness in synthetic filament yarns for apparel and home textile applications.
Use in masterbatches for whitening polyester-based packaging films and engineering plastics.
Optimization of optical brightness in nonwovens used in hygiene and medical products.
