Description

Reactive Blue 184 is a high-purity, reactive dye belonging to the anthraquinone class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering excellent wash and light fastness properties, ensuring vibrant and durable coloration in demanding textile applications. This product is essential for manufacturers in the textile industry seeking reliable and consistent blue shades for cotton, viscose, and other cellulose-based materials. Reactive Blue 184 CAS NO 91254-17-0 is a key component for achieving deep, stable blues in exhaust, pad-batch, and continuous dyeing processes.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing yarns, knits, and woven fabrics in jet, overflow, and beam dyeing machines.
• Pad-Batch Dyeing: Ideal for cold pad-batch processes on woven fabrics, offering high fixation and reproducibility.
• Continuous Dyeing: Used in pad-steam and pad-dry-chemical pad-steam ranges for efficient, high-volume production.
• Viscose and Lyocell Dyeing: Provides excellent dye uptake and color yield on regenerated cellulose fibers.
• Union Dyeing: Suitable for dyeing cotton in blends with polyester or other synthetic fibers.
• Garment Dyeing: Applied for achieving fashionable, wash-down effects on finished denim and apparel.

Quality Control

Every batch of Reactive Blue 184 is subjected to rigorous analytical testing to ensure it meets stringent industry specifications for reactive dye performance. Our quality assurance protocol includes verification of key parameters such as color strength, fixation rate, and solubility. Certificates of Analysis (COA) detailing purity, shade, and application performance are available upon request to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can affect performance.
