Description

Reactive Blue 177 is a high-performance, water-soluble anthraquinone-based reactive dye designed for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant, wash-fast blue shades with excellent reproducibility and good all-around fastness properties. This dye is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, and other cellulose-based materials, where consistent color yield and process reliability are critical.

Application

• Exhaust dyeing and continuous dyeing of cotton and viscose fibers and fabrics.
• Pad-batch and pad-steam dyeing processes for woven and knitted cellulosic textiles.
• Used in the formulation of dyeing recipes for achieving a wide range of navy, royal, and turquoise blue shades.
• Applicable in the dyeing of cellulosic blends with polyester or other synthetics under appropriate conditions.
• Suitable for use in industrial textile printing applications.
• Employed in research and development for new textile dyeing formulations and process optimization.

Quality Control

Our production of Reactive Blue 177 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance. Every lot is tested against key parameters including color strength, shade, solubility, and fixation properties. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and application test results is provided with each shipment to guarantee it meets your specific technical requirements.

Storage

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