Product Details
This dye is chiefly employed for coloring acrylic fabrics and acrylic-blend textiles, delivering vivid red tones with outstanding resistance to light and washing. Its applicability extends to modified polyester (such as cationic-dyeable polyester) and paper, broadening its utility across diverse industrial sectors.
Recognized for its adaptability, the dye supports one-bath dyeing processes—particularly for modified polyester blends—offering reductions in water and energy usage relative to conventional multi-step approaches. This positions it as an environmentally conscious choice in both textile and paper manufacturing.
When stored under refrigerated, inert-atmosphere conditions, the dye remains stable and retains its performance integrity. Its well-established CAS and HS codes facilitate regulatory compliance, streamlining international trade and supply chain logistics.
