Description

Reactive Blue 174 is a high-performance, fiber-reactive dye belonging to the anthraquinone class, widely recognized for its brilliant blue hue and excellent fastness properties. Its primary value lies in delivering consistent, vibrant coloration with strong covalent bonds to cellulosic fibers, ensuring superior wash and light fastness. This product is essential for textile manufacturers and dye houses specializing in cotton, viscose, and other natural fiber dyeing and printing processes. We supply this critical intermediate to the global market, ensuring reliable quality and supply chain stability for industrial-scale operations.

Application

• Primary application in the exhaust dyeing of cotton and viscose yarns and fabrics.
• Used in continuous dyeing processes, such as pad-batch and pad-steam, for uniform coloration.
• Critical component in the manufacturing of reactive dye inks for digital textile printing.
• Employed in the dyeing of cellulosic blends with polyester or nylon.
• Suitable for garment dyeing applications requiring high color yield and reproducibility.
• Used in laboratory settings for research and development of new dye formulations and shades.

Quality Control

Every batch of Reactive Blue 174 is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards critical for consistent dyeing performance, with key parameters including color strength, solubility, and fixation rate rigorously controlled. Our products comply with relevant industry and ecological standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance tests is provided with each shipment.

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 to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
