Disperse Gray FAQ
What makes Disperse Gray different from conventional dyes?
Disperse Gray offers superior dispersion properties that ensure even color distribution and excellent penetration into synthetic fibers. Its advanced molecular structure provides better fastness properties compared to traditional dyes, resulting in longer-lasting coloration with minimal fading even after multiple wash cycles or exposure to harsh environmental conditions.
Can Disperse Gray be used with natural fibers?
While Disperse Gray is primarily formulated for synthetic fibers like polyester, it can be used in combination with certain natural fibers in blended fabrics. However, for optimal results, we recommend conducting small-scale tests before full production runs to verify color consistency and fastness properties specific to your fiber blend.
What safety precautions should be taken when handling Disperse Gray?
Always wear appropriate personal protective equipment including gloves, safety goggles, and dust masks when handling Disperse Gray. Ensure proper ventilation in working areas and avoid creating dust clouds. In case of skin contact, wash immediately with plenty of water. For detailed safety information, refer to the Material Safety Data Sheet provided with each shipment of Disperse Gray.

Disperse Gray FAQ (Continued)
What is the recommended dyeing temperature for Disperse Gray?
For optimal results with polyester fibers, we recommend dyeing temperatures between 125-130°C (257-266°F). This temperature range ensures proper dye penetration and maximum color yield. However, specific conditions may vary depending on your equipment and fabric characteristics, so we advise consulting our technical team for application-specific recommendations.
Does Disperse Gray require special after-treatment processes?
Disperse Gray generally doesn't require special after-treatments for most applications. However, for textiles requiring highest fastness standards, a reduction clearing process with 2g/l sodium hydrosulfite and 2g/l sodium carbonate at 70°C for 20 minutes is recommended. This step removes any superficial dye and improves wash fastness properties by up to 0.5-1 grade on standard scales.
What are the available packaging options for Disperse Gray?
Disperse Gray is available in multiple packaging options to suit different production scales: 25kg multi-layer paper bags with PE liner for standard orders, 500kg bulk containers for large-volume users, and custom packaging solutions for specific requirements. All packaging is designed to ensure product integrity during transportation and storage, with proper moisture barriers to maintain product quality throughout its shelf life.
Environmental Compliance
Disperse Gray meets international environmental standards and complies with the following regulations:
- REACH compliance (EU Regulation No 1907/2006)
- OEKO-TEX Standard 100 Class II certification
- ZDHC MRSL conformance
- EPA Toxic Substances Control Act compliance
Disperse Gray FAQ (Continued)
How does Disperse Gray perform in different pH conditions?
Disperse Gray maintains excellent stability across a wide pH range of 4-9, making it suitable for various dyeing conditions. Optimal dye uptake occurs at pH 5-5.5 for most polyester applications. The product contains built-in pH buffering agents that help maintain stable conditions throughout the dyeing process, but we recommend periodic pH checks for consistent results.
What is the minimum order quantity for Disperse Gray?
Our standard minimum order quantity for Disperse Gray is one full pallet (40 bags of 25kg each), totaling 1 metric ton. However, we offer flexibility for first-time customers or testing purposes with sample quantities starting from 5kg. For customized formulations or special packaging requirements, please contact our sales team to discuss specific quantity needs.
Can Disperse Gray be mixed with other colorants?
Yes, Disperse Gray can be successfully combined with other disperse dyes to create custom shades. Our technical team can provide specific mixing ratios based on desired color outcomes. When blending, we recommend preparing separate dispersions of each component before combining to ensure optimal dispersion quality. Always conduct lab-scale trials before production to verify color matching and fastness properties.
