Description

Reactive Blue 24 is a high-purity, anthraquinone-based reactive dye widely used in industrial textile coloration. Its primary value lies in its ability to form covalent bonds with cellulose fibers, resulting in exceptional wash and light fastness properties. This dye is essential for manufacturers in the textile industry requiring brilliant and durable blue shades on cotton, viscose, and other cellulosic materials. Consistent quality and batch-to-batch uniformity ensure reliable performance in demanding dyeing processes.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, rayon, linen, and other cellulosic fabrics.
• Yarn Dyeing: Used for coloring cellulosic yarns to achieve deep, uniform blue shades with excellent fastness.
• Garment Dyeing: Suitable for dyeing finished cotton garments, providing vibrant and durable color.
• Printing Pastes: Formulated into printing pastes for textile printing applications on cellulosic substrates.
• Industrial Applications: Potential use in coloring paper and leather where reactive dye properties are beneficial.
• Research & Development: Serves as a standard or intermediate in chemical research and dye synthesis laboratories.

Quality Control

Our Reactive Blue 24 is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including spectrophotometric analysis for strength and shade, HPLC for purity and impurity profiling, and tests for solubility and reactivity. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to ensure compliance with your technical requirements and to guarantee batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and incompatible materials. The product is light-sensitive; prolonged exposure to direct light should be avoided to maintain color stability.
