Overview
Reactive Black is a high-performance reactive dye extensively used in the textile industry. It is specifically designed for dyeing cellulosic fibers, forming strong covalent bonds with the fabric. This ensures long-lasting color retention even after repeated washing and exposure to sunlight. The dye is available in powder or granular form and is known for its excellent solubility in water. Its popularity stems from its ability to produce deep, vibrant shades with minimal environmental impact compared to traditional dyes.
Physical and Chemical Properties
Reactive Black is characterized by its dark powder or granular appearance and high solubility in water. It has a density of approximately 1.2-1.5 g/cm³ and exhibits excellent reactivity under alkaline conditions, which is essential for the dyeing process. The dye's chemical structure allows it to form covalent bonds with hydroxyl groups in cellulosic fibers, ensuring superior wash and light fastness. Its leveling properties help achieve uniform dyeing, making it a preferred choice for textile manufacturers.
Main Applications
Reactive Black is primarily used for dyeing cellulosic fibers such as cotton, rayon, and linen. Its ability to form covalent bonds with these fibers ensures long-lasting color retention, making it ideal for high-quality textiles. Beyond textiles, Reactive Black is also employed in paper dyeing and ink production. Its versatility and environmental benefits, such as reduced water pollution compared to other dyes, contribute to its widespread adoption in sustainable manufacturing practices.
Safety and Storage
Handling Reactive Black requires caution to avoid inhalation or skin contact. Protective equipment, including gloves and masks, should be used during handling. The dye should be stored in a cool, dry place away from direct sunlight and moisture to maintain its stability. In case of accidental exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Proper storage and handling ensure the dye's longevity and effectiveness in industrial applications.
B2B Procurement Guide
When procuring Reactive Black, B2B buyers should verify the dye's strength, solubility, and compatibility with other chemicals used in their processes. Reputable suppliers should provide technical data sheets and samples for testing before bulk purchase. Price varies based on purity and supplier, with a typical range of $5-$15 per kg. Buyers should also consider environmental certifications and compliance with international safety standards to ensure sustainable and safe usage.
