Description

C.I. Reactive Red 32 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. This compound is specifically engineered for covalent bonding with cellulosic fibers, delivering excellent wash and light fastness properties. It is a critical component for textile manufacturers and dye houses seeking vibrant, durable red shades on cotton, viscose, and other natural fabrics. Its reliable performance makes it suitable for both exhaust and continuous dyeing processes in industrial settings.

Application

• Textile Dyeing: Primary application for dyeing cotton, rayon, linen, and other cellulosic fibers to achieve bright red hues.
• Exhaust Dyeing Processes: Used in batch dyeing methods such as jet, beck, and beam dyeing for uniform color penetration.
• Continuous Dyeing: Applied in pad-batch and pad-steam continuous dyeing ranges for high-volume production efficiency.
• Garment Dyeing: Suitable for dyeing finished knitted or woven garments to meet specific color demands.
• Yarn Dyeing: Employed for coloring yarns in hank or package form for subsequent weaving or knitting.
• Technical Textiles: Can be used for coloring textiles where color consistency and fastness are critical.

Quality Control

Our C.I. Reactive Red 32 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including color strength, shade, solubility, and fixation rate. Certificates of Analysis (COA) detailing purity, physical properties, and application performance are provided with every shipment to support your quality assurance protocols.

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. The product is hygroscopic (moisture-sensitive); ensure the original packaging is sealed after use to prevent moisture absorption and caking.
