Purity 98%: Disperse Blue 291:1 with purity 98% is used in polyester fabric dyeing, where high color yield and consistent shade reproduction are achieved. Particle size D50 2 μm: Disperse Blue 291:1 with particle size D50 2 μm is used in high-speed dyeing machines, where rapid dispersion and minimal agglomeration result in uniform coloring. Stability temperature 130°C: Disperse Blue 291:1 with stability temperature 130°C is used in thermosol dyeing processes, where color fastness and dye integrity are maintained under heat. Molecular weight 450 g/mol: Disperse Blue 291:1 with molecular weight 450 g/mol is used in synthetic fiber finishing, where penetration depth and wash resistance are enhanced. Melting point 170°C: Disperse Blue 291:1 with melting point 170°C is used in automotive textile coating, where thermal stability prevents dye migration during lamination. Lightfastness grade 5: Disperse Blue 291:1 with lightfastness grade 5 is used in sportswear manufacturing, where prolonged exposure to sunlight does not diminish vibrancy. Viscosity 25 mPa·s: Disperse Blue 291:1 with viscosity 25 mPa·s is used in inkjet textile printing, where stable flow properties ensure sharp image quality and minimal nozzle clogging. pH stability 4.5–7: Disperse Blue 291:1 with pH stability 4.5–7 is used in alkaline dye bath applications, where chemical resistance ensures retention of initial shade and uniform dyeing. Fastness to washing 4/5: Disperse Blue 291:1 with fastness to washing 4/5 is used in home textile production, where repeated laundering does not compromise color retention. Solubility in water <0.01 g/L: Disperse Blue 291:1 with solubility in water <0.01 g/L is used in nonaqueous printing pastes, where minimal dye bleeding ensures crisp patterns. |
