As an accredited Direct Dyes factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging for Direct Dyes consists of a sealed 25 kg fiber drum with inner polyethylene lining, clearly labeled for safe handling. |
| Shipping | Direct dyes are shipped in tightly sealed, moisture-proof bags or drums to prevent contamination and moisture absorption. Packaging complies with safety regulations, clearly labeled with product and hazard information. Containers are handled with care to avoid spills, transported in covered vehicles, and stored in cool, dry conditions during transit. |
| Storage | Direct dyes should be stored in tightly sealed containers, away from moisture, direct sunlight, and sources of heat. The storage area should be cool, dry, well-ventilated, and free from incompatible substances such as strong oxidizers. Proper labeling and safe handling are essential to prevent contamination and accidental exposure. Personal protective equipment should be readily available near the storage site. |

Purity 98%: Direct Dyes with purity 98% is used in paper coloring operations, where high chromatic consistency and reproducibility are achieved. Solubility (g/L at 25°C): Direct Dyes with solubility 100 g/L at 25°C is used in textile dip-dyeing, where rapid and uniform dye uptake is ensured. Molecular weight 650 Da: Direct Dyes of molecular weight 650 Da is used in viscose rayon dyeing, where deep penetration and vivid shades result. pH stability 4–8: Direct Dyes stable at pH 4–8 are used in cotton fabric processing, where color integrity is maintained throughout various finishing conditions. Light fastness grade 5: Direct Dyes with light fastness grade 5 is used in drapery manufacturing, where colors remain vibrant after prolonged light exposure. Particle size <10 µm: Direct Dyes with particle size below 10 µm is used in inkjet textile printing, where enhanced dispersion and sharp image resolution occur. Melting point 210°C: Direct Dyes with melting point 210°C is used in heat-set printing applications, where dye performance remains reliable under thermal conditions. Stability temperature 90°C: Direct Dyes with stability up to 90°C is used in hot-water dye baths, where color retention is preserved during high-temperature processes. Viscosity grade low: Direct Dyes with low viscosity grade is used in continuous dyeing machines, where efficient pumpability and even fabric coverage are realized. Wash fastness grade 4: Direct Dyes with wash fastness grade 4 is used in institutional uniform production, where repeated laundering does not diminish color intensity. |
