Description

Reactive Orange 16 is a highly reactive, water-soluble azo dye belonging to the vinyl sulfone class of reactive dyes. It is valued for its excellent wash and light fastness properties, forming a strong covalent bond with cellulose fibers during the dyeing process. This product is essential for textile manufacturers and dye houses seeking vibrant, durable orange to red-orange shades on cotton, viscose, and other cellulosic materials. Its reliable performance makes it a staple in exhaust, pad-batch, and continuous dyeing applications.

Application

• Textile Dyeing: Primary application for dyeing cotton, rayon, linen, and other cellulosic fibers to achieve bright orange hues.
• Exhaust Dyeing: Used in batch-wise dyeing processes in jiggers, winches, and jet dyeing machines.
• Continuous Dyeing: Applied in pad-dry-chemical pad-steam processes for high-volume fabric production.
• Cold Pad-Batch Dyeing: Ideal for energy-efficient dyeing at room temperature, suitable for knit and woven fabrics.
• Yarn Dyeing: Employed for dyeing cellulosic yarns in package or hank form.
• Union Dyeing: Can be used in combination with other dyes for coloring blended fabrics containing cellulose.
• Ink Formulation: Potential use as a colorant in specialized ink formulations for non-textile applications.

Quality Control

Our Reactive Orange 16 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 properties. A Certificate of Analysis (COA) detailing purity, physical properties, and application test results is provided with every shipment to guarantee it meets the specifications required for industrial textile dyeing.

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